Electronic products floods our daily life,what do you think of it?

Students with contemporary electronic products grew up together, to promote a new generation can not be questioned.Young people to learn and accumulate new knowledge, generating positive energy, but also to the undeniable.The lives of many of the younger generation of negative energy. Computers, mobile phones, ipad itouch,mps3, p4, p5, psp.rray of electronic products has become a new generation of young people pet.Children, synonymous with fashion family. However, more and more electronic products charging people raw red,Live serving the same time, some small risks caused quietly.

On the physical properties of the surface electronic products made : at present, the world recognized six to human health.The greatest threat to harmful elements , namely, lead Pb, Cd cd, Mercury Hg, hexavalent chromium cr6 +, and morePolybrominated diphenyl ethers PBDE, polybrominated biphenyls PBB. These types of traditional mainstream electronics products will be used.Toxic substances, they unknowingly harm our body mysteriously . Radiation protection, anti-radiation.Shot in recent years, users of the word is more and more electronic products in that it is clear.They have realized that the radiation hazards . Radiation pollution affects the body's circulatory system , immune,Reproductive and metabolic function , but also a serious cause cancer , and will accelerate the growth of human cancer.Colonization . Radiation can really do , people use these products, using a variety of the world face.Radiation of new products , new products chatter about how to magical effect , production.Manufacturers also make every effort to do , and then constantly updated with new products. However , electromagnetic waves on human.Effect is not a simple question , one can not rule out a slight radiation harmful to human health.Possibilities. And with relevant statistics, because the radiation produced by chronic diseases every yearRise.

The negative impact of electronic products is only body? No, adult Leaving aside , at On the growth of young people without a correct understanding , that would be what results ? Can not use words.Declare to the phone , for example, to talk about the growth of the students have what hazards.First, from the physical point of view, mobile phone radiation on long-term adverse physical development of students .University of London Professor Gail and the study of human brain cells, the author pointed out , so that normal rats.Accepted 4 hours of continuous frequency range of mobile phone radiation exposure to radio waves similar after the rats.Brain cells, DNA structures have been signs of damage . Studies have shown that children use mobile phones.When the brain absorbs radiation than adults to be higher than 50%. Integrative Medicine Hospital of Lanzhou.Liangxuan Mei said , there are a lot of young people are using cell phones, thought it was not much of a bodyAffected. In fact , young people 's immune systems vulnerable than adults , so more vulnerable to radiation shadowRang . Proved . Mobile phone radiation on young people with brain damage , causing headaches,Memory loss and sleep disorders. And frequently play mobile games is also possible for children to deafness, up To 85 db is likely to cause hearing loss.

Secondly, the phone in the case of improper use, the impact of the formation of good quality students.

In recent years, various types of examinations of students cheating using a mobile phone is not new. 2004 6 May my school final examination found that individual students use mobile phones to cheat; 2004 in Hubei Qianjiang entrance, stone First, the use of mobile phones have undergone Nanchangosaurus fraud thing, another example, fraud and other white power entrance. With Enhanced popularity of mobile phones with features, the growing use of mobile phones cheating. And doing more To the more subtle, such as the headset strapped sleeves, put your hands near the headset exam pretending to think, real Quality listening through the phone came the answer. Girls are more convenient, some simply wearing headphones .Long hair on the ears and then covered, the invigilator difficult to find. In addition, students have a cell phone lying.Is nothing new. Particularly, some students weariness, obviously in Internet cafes playing games, but he lied in

school homework. Some students also to make fun of teachers and students, such as a text message. Regardless Cheating, lying or send false messages are not the manifestation of good faith, if not stop Canadian Proper guidance, the students will form a good quality bring serious harm.

The digital products let us lazy

There is a scene for the students that we are too familiar with --- playing mobile phone and playing computer all the time and regardless of on class or not.In a whole day of 24 hours, we will spend at least eight hours to face with high-definition mobile phone or computer screen. Today’s people use the cell phones and other electronic equipment to complete some work even in the exercise. The most important is that it can help them to pass some time, eliminating boredom.

Many people feel this habit is normal no more. Using these electronic devices with some entertainment features to extract the boredom without any harm. However, there are some American scientists who have pointed out that these casual little habits have brought an unexpected side effect: when people make their brain too busy to accept the continuing digital information, they will lose the necessary "rest time” for their brain. "Do not underestimate the "rest time", which is an irreplaceable way that it allows people to better learn and remember information, or hold a thought of a new. In other words, the use of electronic products in a "multitasking" way is easy to damage the brain's ability to learn. Like calligraphy and typing, and now, there will be such a phenomenon - people typing faster and faster while their handwriting is getting worse. Otherwise, today’s students are not as focusing on their peers’ neat standardized font as the past years. "A lot of kids think that the chance of handwriting is very little in the future. The only thing they should notice is to write in the line and not care the wording is graceful”.“More exaggeratedly, as long as the time goes, the words we usually come in handy are “disappeared”. And just like my classmates said, "After playing for a few years computers, a lot of words they just know, but do not know how to write." As is known to all that the popularizing of computer in life has greatly improved people's working efficiency. But at the same time, due to have an excessive dependence on the "keyboard" ,many people have the phenomenon of forgetting words in pen, leaving the computer on the thinking of a short circuit, and growing poor handwriting. In "paperless" age, "handwritten” will really drift away yet?

Chinese calligraphy art has always been a proud of the cultural treasures, but this art have gradually appeared in an "aging" trend. Calligraphy, character assessment, quality word, these fun writing characters are becoming more and stranger for a new generation.

May 2011, the Ministry of Education, the State Language Commission released the 2010 Chinese Language Situation Report. The report noted that with the arrival of the information age, the Chinese student’s abilities have decreased not only in reading, but also in writing. August 2011, the Ministry of Education issued a notice that in the primary and secondary school, it will carry out calligraphy education through curriculum and related activities. The notification requires that the introduction of calligraphy education in compulsory language courses must be in accordance with the requirements of curriculum standards, the calligraphy lesson in three to sixth grade language courses a week for a lesson.

In real life, there are more people will not care about their own handwriting degradation or even does not care about they are write wrong. Because the “handwritten era” has passed, the universal keyboard makes most people completing the writing of Chinese characters by known pinyin only.But using this convenient way more frequently will lead to people use the specific wording of Chinese characters become increasingly blurred. Someone made a "symptom analysis": because of tying the words along with the computer and the phone so frequently and lacking a sense of handwriting and a sense of writing that the language center of the brain does not produce a stimulating effect and resulting in a temporary amnesia cortex.

Technological innovation in the field of communication for people to exchange information with each other, provide emotional r fast https://www.360docs.net/doc/3c3446766.html,air and simple modern means, with the popularization of 3G

mobile phones, more and more functions can be rtable completed, in which more and more electronic products for all services, all types of electronic roducts also quietly entered the classroom, students can access at any time in the classroom, information search,However, by phone QQ chat, web browsing, online fiction is increasingly becoming mainstream. Lesson.Classroom often have the phone rings, the student texting, whispering to each other to share their receipt.Interesting information, disrupt classroom order phenomenon has no chance.

Students face the dangers arising from the use of mobile phones and the presence of a variety of physical and mental health.Problem has attracted the attention of the community, relying only on the original school education with Germany.Remediation work hard to cope with the situation. In order to change the existing passive state school education, it is necessary to Canton.Pan conduct mental health advocacy and social science education, school education and family education combined,Schools should also increase mental health classes and health education classes, in order to guide students to establish the right people.Health concept, correct and reasonable use of the phone.

Digital products to harm our body

With the accelerated pace of work and the information appeared in large numbers, the first thing many people will do after their get up is to open their mobile phone’s software and glance at the daily news. Many people like sending a message when they are walking or using a mobile phone or iPad for watching movies, playing games, reading e-books on the bus. In this regard, some experts pointed out that using a mobile phone while walking is usually make people look down at the screen hardly and made the neck, the shoulders and the spine under enormous pressure and reduced the blood flow, the poor blood flow will make the neck, shoulders and spine stiffness and pain, and even inflammation. In addition, looking at the screen in unstable state is easy to cause eye dryness and fatigue and to affect vision thereby. And this behavior can lead to not hear car horns or not see stairs and the traffic accidents will happen easily.

Besides, many people have dependency to the digit products with the popularity of microblogging. Not only during the day time stop using all fragmented they will not only interstice of time in daily life to brush the microblogging ceaselessly , but also open the microblogging at bedtime to see if anyone interaction uncontrollably. This kind of update make the time difficult to be controlled down. Some people made a rough estimate microblogging dependency syndrome "patient" who has reduced the sleep time at least three hours for playing phone.

A recent study shows that most people forced out after a day of technology products, will feel severe psychological and physiological discomfort , panic, confusion and extreme loneliness after be forced out to the technology products a day. These symptoms are very familiar with the feeling ofdependent user who abandon drug habits or quit smoking unexpectedly, which is called "high tech addiction" disease.

Though digital products has brought us convenience, but also let us getting lazy, the more worse is it will bring harm to our body. A cancer research expert of UK recently reached an astonishing conclusion: the number of deaths due to use of mobile phones will surpass smoking victims. This is so far the most serious warning that the phone will probably bring harm to our health. Community mobile phone users have reached three times as much as the number of smokers. Therefore, Khurana believes that mobile phones have more serious harm than cigarettes. There are 500 million people worldwide die of smoking-caused each year currently. Today, mobile phones are no longer a simple conversation tool, but also an entertainment device including a function of MP3. According to the U.S. Centers for Disease Control and Prevention data show that 12.5 percent of children and adolescents (6-19 years old) and 17% of adults (20-69 years old), approximately 30 million people, have been caused permanent hearing damage due to excessive noise. In normal conversation, the voice is 60 decibels, 85 db may damage hearing and MP3 sound from the headphones up to 100 decibels.

The intuitionistic effect that playing computer has brought is playing games. Pros and cons of playing

electronic products have both advantages and disadvantages, but in general, there is more harm than good. The game in electronic products can enhance our practical abilities, which is favorable aspect. However, the disadvantages of playing electronic products are far greater than the benefits. The main reasons are that with the electronic products’ screen brightness and contrast always change, taking a long time on screen will have the result that a man who has long lifted his arm and makes his muscles stiff. Similarly, because irrational contrast, brightness, flashing electronic screens, people closing look at an object will make the ciliaris move frequently and cause eye fatigue. , if work over time, the ciliaris will spasm and cause pseudo-myopia. If pseudo myopia receives treatment timely in 1 to 3 months, it can restore normal vision. But it will evolve into a true myopia soon if the treatment posterior to the best period.

With the continuous development of network technology, science and technology popularization of electronic products, communications creatorNew, more and more electronic products appear in life, for people to exchange information with each other, passingEmotion provides a quick and simple modern means. To build an immeasurable level of economic developmentTaiwan; however, people enjoy electronic products has brought us a new era at the same time, is not s also to think about how to properly use to play the biggest role, and the negative impact.Minimize the impact. How to make our next generation of electronic products for the right to work, study.And entertainment, rather than indulging in online novels, online games, chat?? HowBetter use of this double-edged sword? Hope that more students to the right face, the right to make.With the hope that my article you can have alerts.

To our knowledge broaden our horizons a reasonable right to use your hands electronic products.

电子产品充斥我们的日常生活中,你有什么感想呢?

与当代学生一起成长起来的电子产品,不容质疑的推动了新一代年轻人对新知识的学习和积累,在产生正能量的同时,也不可否认给众多的新新人类的生活产生了负能量。计算机,手机,ipad itouch,ps3,p4,p5,psp。琅满目的电子产品成了新一代年轻人的宠儿,时尚一族的代名词。然而在越来越多的电子产品充赤着人们的生活,为人民服务的同时,一些微小的隐患也悄然而致。

就电子产品的物理属性面言:目前,世界公认的六类对人体健康威胁最大的有害元素,分别是铅Pb,镉cd,汞Hg,六价铬cr6+,多溴二苯醚PBDE,多溴联苯PBB。传统主流的电子产品都会用的这几类有毒物质,他们在神不知鬼不觉的危害着我们的身体。防辐射,防辐射,近年来,这个词被越来越多的电子产品的使用者在说,很明显人们已经意识到辐射的危害。辐射污染会影响人体的循环系统、免疫、生殖和代谢功能,严重的还会诱发癌症、并会加速人体的癌细胞增殖。真的能防辐射吗,人们在使用这些产品的同时,采用各种世面上防辐射的新产品,新产品也喋喋不休的讲述着如何神奇的功效,生产商也在尽一切力量在做,再不断更新新产品。然而,电磁波对人类的影响并不是一个简单的问题,人们不能排除轻微辐射对人类健康有害的可能性。并且具有关部门统计,因为辐射产生的慢性疾病每年都在上升。

电子产品的负面影响仅仅是身体吗?不是的,成人暂且不说,处于成长的青少年如果没有正确认识,那会是怎样的结果?无法用文字述说,以手机为例,谈一谈对成长中的学生会有怎样的危害。首先从身体角度出发,手机长期的辐射对学生的身体发育不利。伦敦大学研究人类脑神经及细胞的盖尔教授撰文指出,让正常的白鼠连续接受4小时频率范围与手机辐射近似的无线电波辐射后,白鼠的脑细胞,DNA结构均有被破坏的迹象。有研究表明,孩子在使用手机时,大脑中吸收的辐射比成年人要高出50%。兰州中西医结合医院的梁宣梅说,现在有很多青少年都在使用手机,以为这对身体没多大影响。其实,青少年的免疫系统比成人要脆弱,所以更容易受辐射影响。事实证明。手机辐射对青

少年脑部神经造成损害,引起头痛,记忆力减退和睡眠失调。而频繁玩手机游戏也有可能使孩子耳聋,达到85分贝就有可能损害听力。

其次,手机在使用不当的情况下,影响学生良好品质的形成。

近年来各类考试学生用手机作弊已经不是什么新鲜事。2004年6月我校期末考试发现个别学生用手机作弊;2004年高考在湖北潜江,石首,南漳都发生了利用手机舞弊的事,再如电白高考舞弊案等。随着手机的普及与功能的增强,利用手机作弊现象日益增多。而且做得越来越巧妙,如将耳机绑在袖子里,考试时将手靠近耳机佯装思考,实质在听通过手机传来的答案。女生则更方便了,有的干脆将耳机戴在耳朵上再用长发遮住,监考老师很难发现。此外,学生打手机说谎也是司空见惯的事。特别是部分厌学的学生,明明在网吧玩游戏,他却谎称在学校复习功课。有的学生还以短信方式捉弄老师同学等。无论是作弊,说谎还是发虚假短信都是不诚信的表现,如不及时制止和加以正确引导,会对学生良好品质的形成带来严重危害。

数码产品让我们懒惰

对于学生,有这样熟悉的场景——无论在不在课堂,大家都在玩手机或玩电脑。一天24小时,我们至少花了8小时来面对高清手机或电脑屏幕。现在,人们配备移动电话和一些其他的电子产品,并以此来完成一些工作甚至运动。重要的是,这些产品确实帮助了一些人熬过了无聊的时间。

很多人都觉得这种习惯再正常不过了。使用这些电子设备来进行一些娱乐活动,消除一下无聊,这不会有什么伤害的。然而,还是有些美国科学家提出了这些休闲小习惯带来了意想不到的副作用:人们持续地接受数字信息使他们的大脑太繁忙,这样他们将失去必要的大脑“休息时间”。不要小看休息时间,这是一个不可替代的,它可以让人们更好地学习和记忆的信息,或持有的一个新思路。换句话说,在一个“多任务处理”的方式使用电子产品很容易损伤大脑的学习能力。像书法和打字,现在,会有这样一个现象——人们打字更快,而他们的笔迹越来越差。否则,今天的学生是不会专注于他们的同龄人整齐规范的字体,就像过去那样。“很多孩子认为在将来手写的机会很少。他们应该注意到的唯一一件事就是写成一行但不关心的措辞优美,更夸张的是,只要随着时间的推移,我们通常会派上用场的话是“失踪”。而且就像我的同学说的:“打了几年的电脑,很多的话,他们只知道,但不知道怎么写。”众所周知,计算机在生活中的普及,极大地提高了人们的工作效率,但与此同时,由于人们有“键盘”上的过度依赖,很多人都忘了钢笔字,离开了计算机就会思维短路,同时有越来越多的人写得一手难看的字。在“无纸化”时代,“手写”真的会渐行渐远了吗?

中国书法艺术一直是一个骄傲的文化瑰宝,但这种艺术已逐渐出现了一个“老龄化”的趋势。对于年轻一代人来说,这些有趣的文字的特点和意义正在变得越来越奇怪。

2011年5月,教育部,国家语言文字工作委员会发布了2010年中国语言生活状况报告。该报告指出,随着信息时代的到来,中国学生的能力都在下降,这并不仅仅是在读书方面,也在写作这方面。2011年8月,教育部下发通知,在小学和中学将开展书法教育通过课程及相关活动。通知要求,必须按照课程标准的要求将书法教育引入义务教育三到六年级的语文课程,并且要求每周一节课。

在现实生活中,有更多的人不会在乎自己的手写能力退化,甚至不关心自己书写上的错误。因为“手写时代”已经过去,通用键盘使得大部分人仅仅用已知的拼音来完成中国文字。但频繁使用这种便捷的方式会导致人们对中国文字的具体写法越来越模糊。有人提出了“症状分析”:因为频繁地在电脑和手机上敲打文字,并且缺乏手写的感觉,这样便不会对大脑的语言中枢产生刺激作用,并导致暂时性失忆的症状。

通讯领域的科技创新,为人们相互交流信息,传递情感提供快捷而简便的现代手段,随着3G手机的普及推广,越来越多的功能可以随身完成,就在这越来越多的电子产品为大家服务的同时,各类电子产品也悄然走进了课堂,学生可以直接在教室里随时上网,查资料,但通过手机进行QQ聊天、网页浏览,网上小说也越来越成为主流。课堂上经常会有手机铃声响起,学生发短信,交头接耳地交流各自收到的有趣信息,打乱课堂秩序的现象已不偶然。

面对学生使用手机所带来的危害性及存在的各种生理和心理健康问题,已经引起了社会各界的重视,仅仅靠学校原有的教育教学与德育工作难于应付局面。为了改变现有学校教育的被动状态,有必要广泛开展心理卫生科普宣传和社会教育、学校教育和家庭教育相结合,学校也要增加心理卫生课和

健康教育课,从而引导学生树立正确的人生观,正确合理地使用手机。

数码产品危害我们的身体

随着大量出现的工作和信息化步伐加快,很多人起床后会做的第一件事,就是打开自己手机的软件和一目了然的每日新闻。很多人喜欢在走路时发送消息,或用手机或iPad看电影,玩游戏,在线阅读电子书。对此,有专家指出,走路时使用移动电话通常会让人的视线几乎不离开屏幕,并会让脖子和肩膀承受巨大的压力,脊椎的血流量会减少,血流不佳将使颈部、肩部和脊柱僵硬和疼痛,甚至发炎。此外,看着在不稳定的状态下看屏幕很容易造成眼睛干涩和疲劳,从而影响视力。还有,这种行为可能会导致听不到汽车喇叭或看不到路,这样,交通事故会很容易地发生。

此外,很多人都因为微博的普及而依赖数字产品。不仅在白天的琐碎时间里刷微博,而且在睡觉前还要看一下是否有人在微博上与自己互动。这种更新确实难以控制下来。有些人做了一个粗略的估计,微博依赖症“患者”的睡眠时间减少了,而玩手机的时间至少有三个小时。

最近的一项研究表明,大多数人在使用科技产品一整天后,会感到严重的心理和生理上的不适,恐慌,混乱和极端的孤独。这些症状与滥用药品和戒烟意外都非常相似,这就是所谓的“高科技依赖症”疾病。

虽然数码产品给我们带来了方便,同时也让我们越来越懒,更糟糕的是它会伤害我们的健康。英国癌症研究专家近日得出了惊人的结论:因使用手机的死亡人数将超过吸烟致死的人数。这是迄今为止,手机可能会给我们带来伤害的最严重的警告。移动电话用户数已经达到烟民的数量三倍之多。因此,库拉纳认为,手机比香烟有更严重的危害。目前,每年还有500多万人死于吸烟。如今,手机已不再是简单的对话的工具,也是一种娱乐设备,其中包括MP3的功能。据美国疾病控制和预防中心的数据显示,12.5%的儿童和青少年(6-19岁)和17%的成人(20-69岁),约30万人,由于过度的噪音已有永久性听力损害。在正常的交谈中,声音为60分贝,85分贝到高达100分贝的耳机声音可能会损坏听力。

那玩电脑游戏带来的直观效果是。玩电子产品有优点也有缺点,但总的来说,弊大于利。电子游戏可以提高自己的能力,这是有利的方面。然而,玩电子产品的缺点远远大于益处。其主要原因是,随着电子产品的屏幕亮度和对比度的提升,花费很长的时间在屏幕上会让一个一直举着手臂的人肌肉僵硬。同样,由于不合理的对比度、亮度和闪烁的电子屏幕,人们近距离看一个物体将会使睫状肌频繁移动,造成眼睛疲劳。如果睫状肌处于长时间工作状态中,睫状肌就会痉挛,这便造成假性近视。如果假性近视在1~3个月内得到及时治疗,就可以恢复正常视力。但如果在最佳时期后治疗,它会发展成真性近视。

随着网络技术的不断发展,电子产品的普及,通讯领域的科技创新,电子产品越来越多的出现在生活中,为人们相互交流信息,传递情感提供了快捷而简便的现代手段。为经济建设搭建不可估量的平台;然而在人们享受电子产品给我们带来的全新时代的同时,是不是也考虑一下,如何正确的使用,才能发挥最大的作用,而把负面影响降到最低。如何让我们的下一代正确的将电子产品用于工作、学习和娱乐,而不是沉迷于网络小说,网络游戏,聊天.如何更好的使用这把双刃剑。希望更多的学生能够正确的面对,正确的使用,希望我的这篇文章能对你有所警示。

为增长我们的知识开阔我们的眼界合理正确的使用你手里的电子产品吧。

Doctors of that time knew very little about causes of sickness or ways of preventing it. Thousands of men in poor health became soldiers. Hundreds of others had never had childhood diseases. Many of these soldiers could not withstand the epidemics of measles, mumps, and whooping cough that went through the camps. Army life was hard. Soldiers got few fruits or vegetables. There was no milk unless they happened to find a cow. Neither their clothes nor their shelters protected the troops from rain, snow, and cold. Sickness and disease were spread by insects, rats, and impure drinking water. Often the men drank straight from muddy streams. Gunshot wounds were serious, as in any war,

电力系统自动化试卷及思考题答案2014年(华北电力大学)

1.那些实验是在EMS平台下进行?那些实验是在DTS平台下进行? EMS:1)电力系统有功功率分布及分析;2)电力系统无功功率分布及分析;3)电力系统综合调压措施分析;4)电力系统有功-频率分布;5)电力系统潮流控制分析;6)电力系统对称故障计算及分析;7)电力系统不对称故障及计算分析 DTS:1)电力系统继电保护动作特性分析;2)电力系统稳定性计算及分析;3)电力系统继电保护动作情况与系统稳定性关系分析 2.欲调节电压幅值,调有功P有效还是无功Q有效?为什么? 1)电压对无功变化更敏感,有功虽然对电压也有影响但是比较小 2)只考虑电压降落的纵分量:△U=(PR+QX)/U,从公式看出,电压降落跟有功P和无功Q 都有关系,只不过在高压输电系统中,电抗X>>R,这样,QX在△U的分量更大,调节电压幅值就是在调节无功。 3.重合闸有什么好处?若电气故障设为三相短路,故障分别持续t1和t2时长,则两个实验结果有什么不同? 重合闸好处:1)在线路发生暂时性故障时,迅速恢复供电,从而提高供电可靠性;2)对于有双侧电源的高压输电线路,可以提高系统并列运行的稳定性,从而提高线路的输送容量;3)可以纠正由于断路器机构不良,或继电器误动作引起的误跳闸 故障延时长的接地距离一段动作次数,相间距离一段动作次数,三相跳开次数比故障延时短的多,开关三相跳开的次数多。 4,.以实验为例,举例说明继电保护对暂态稳定的影响? 实验八中,实验项目一体现出选保护具有选择性,当其故障范围内出现故障时,有相应的断路器动作跳闸。实验项目二体现出保护是相互配合的。当本段拒动时,由上一级出口动作跳闸。实验项目三做的是自动重合闸的“前加速”和“后加速”保护。继电保护快速切除故障和自动重合闸装置就是使故障对系统的影响降到最低,尽早的将故障切除能避免故障电流对设备的冲击减小对系统的扰动,有利于暂态稳定的实现。 5.·在电力系统潮流控制分析试验中,可以通过改变发电机的无功进行潮流调整,也可以通过改变发电机所连升压变压器的分接头进行潮流调整,实验过程中这两项调整对发电机的设置有何不同?为什么? 改变发电机无功:设置发电机无功时以10MV AR增长。不能保证发电机有功功率和发电机电压恒定,他们可能会随着无功功率的改变有微小的变化。 改变变压器分接头:设置此时发电机相当于一个PV节点,即恒定的有功P和不变的电压U。原因:发电机是无功电源,也是有功电源,是电能发生元件;变压器是电能转换元件,不产生功率。 7在实验中考虑了哪些调压措施?若某节点电压(kv)/无功……电压升高3kv,则应补偿多少电容? 【实验】调节发电机端电压(调节有功,调节无功),调整变压器分接头 【百度】电力系统的调压措施主要有: 1靠调节发电机机端电压调压 2靠改变变压器分接头调压 3靠无功补偿调压 4靠线路串连电容改变线路参数调压 我的实验灵敏度系数为0.075,所以若电压升高3kv,应补偿3/0.075=40Mvar的电容 8在调频实验中。对单机单负荷系统,若发电机的额定功率……频率怎么变化?当负荷功率大于发电机功率的额定功率…… 通过K=△p/△f来判断f如何变化 9、几个实验步骤 实验九试探法求故障切除实验的实验步骤

Robot Competition From 11th to 13th October 2013, these three days are special for my teammates and me. I took part in the fifth Robot Competition of Anhui province. After continuous efforts, we got the third prize in the end. In April 2013, this competition was announced in our class by Mr He. In that moment, many students registered for the competition. After hardly training, there were only fifteen students remaining. We were divided into five teams. Each included three people. There were three teams taking part in wheel type robot competition (or named intelligent car). And the other two majored in dancing robot. My two roommates and I engaged in the designing of robot dance. We controlled the robots by program. But the program was programmed in BASIC, which is a high level programming language. The problem was that we had never touched to that language besides C or C++. So, we must learn the language before designing the action. It seemed difficult but we had never lost our courage. After seeking enough data from the Internet and the library, we spent about a few weeks to learn it. When we felt the fundamental grammar was easy, we began to design the dancing action. That was the most important and most difficult part. We spent much time on

华北电力大学电力系统分析考研及期末考试必备

华北电力大学电力系统分析考研及期末考试必备 1、什么是动力系统、电力系统、电力网? 答:通常把发电企业的动力设施、设备和发电、输电、变电、配电、用电设备及相应的辅助系统组成的电能热能生产、输送、分配、使用的统一整体称为动力系统; 把由发电、输电、变电、配电、用电设备及相应的辅助系统组成的电能生产、输送、分配、使用的统一整体称为电力系统; 把由输电、变电、配电设备及相应的辅助系统组成的联系发电与用电的统一整体称为电力网。 2、现代电网有哪些特点? 答:1、由较强的超高压系统构成主网架。2、各电网之间联系较强,电压等级相对简化。3、具有足够的调峰、调频、调压容量,能够实现自动发电控制,有较高的供电可靠性。4、具有相应的安全稳定控制系统,高度自动化的监控系统和高度现代化的通信系统。5、具有适应电力市场运营的技术支持系统,有利于合理利用能源。 3、区域电网互联的意义与作用是什么? 答:1、可以合理利用能源,加强环境保护,有利于电力工业的可持续发展。 2、可安装大容量、高效能火电机组、水电机组和核电机组,有利于降低造价,节约能源,加快电力建设速度。 3、可以利用时差、温差,错开用电高峰,利用各地区用电的非同时性进行负荷调整,减少备用容量和装机容量。 4、可以在各地区之间互供电力、互通有无、互为备用,可减少事故备用容量,增强抵御事故能力,提高电网安全水平和供电可靠性。 5、能承受较大的冲击负荷,有利于改善电能质量。 6、可以跨流域调节水电,并在更大范围内进行水火电经济调度,取得更大的经济效益。 4、电网无功补偿的原则是什么? 答:电网无功补偿的原则是电网无功补偿应基本上按分层分区和就地平衡原则考虑,并应能随负荷或电压进行调整,保证系统各枢纽点的电压在正常和事故后均能满足规定的要求,避免经长距离线路或多级变压器传送无功功率。 5、简述电力系统电压特性与频率特性的区别是什么? 答:电力系统的频率特性取决于负荷的频率特性和发电机的频率特性(负荷随频率的变化而变化的特性叫负荷的频率特性。发电机组的出力随频率的变化而变化的特性叫发电机的频率特性),它是由系统的有功负荷平衡决定的,且与网络结构(网络阻抗)关系不大。在非振荡情况下,同一电力系统的稳态频率是相同的。因此,系统频率可以集中调整控制。 电力系统的电压特性与电力系统的频率特性则不相同。电力系统各节点的电压通常情况下是不完全相同的,主要取决于各区的有功和无功供需平衡情况,也与网络结构(网络阻抗)有较大关系。因此,电压不能全网集中统一调整,只能分区调整控制。

电力系统分析-博士入学考试习题及答案-华电

华北电力大学(北京) 2005年博士研究生入学考试试题(B) 解答下列各题(每题10分,共100分) 1、近几年我国多数地区出现了“电荒”现象,各地不得不采取拉闸限电措施,而10年前 我国的电力还是供大于求,你如何分析这种现象?对电力的规划和发展有何良策? 答案1:出现‘电荒’的原因:在“九五”期间特别是电力供应过剩之后,人们对电力工业是否应成为先行工业,有了不同的看法和不同的声音,这成为导致2002年开始出现较大范围缺电的重要原因之一。再加上多年来只高度重视电源,对电网协调发展有所忽视。即既有电源容量不足、又有电网结构薄弱问题,造成了电力短缺。 建议措施包括:建立电力安全危机管理机制,确保电网运行安全;进一步加强需求管理;深化电价改革,尽快形成分环节电价机制;完善宏观调控,深化电力项目审批制度改革,解决无序建设难题;加强协调,确保电煤供应;合理安排机组检修,提高设备健康水平;协调好水力调运与发电关系,提高水能利用率等。 答案2:产生‘电荒’的原因:(1)煤电价格冲突,凸显体制困局;(2)高耗能行业告诉增长,使电力供应对经济增长的支撑能力下降;(3)电力投资连年偏低,造成电力供应能力不足;(4)持续高温、干旱和水电不足,增加了随机性缺电;(5)省间电力壁垒困扰电力供应。 建议措施:加快电力建设同时抑制不合理需求;开发和节约并举;加大结构调整力度,租金产业升级;西电东送以资源换市场;发展循环经济,实行清洁生产;多元化开发电力资源。 2、什么是电力系统的可靠性?有哪些主要的研究内容? 答案:电力系统可靠性是对电力系统按可接受的质量标准和所需数量不间断地向电力用户供应电力和电能量之能力的度量。电力系统可靠性包括充裕度和安全性两个方面。 充裕度是指电力系统维持连续供给用户总的电力需求和总的电能量的能力,同时考虑到系统元件的计划停运及合理的期望非计划停运。充裕度又称静态可靠性,也就是在静态条件下,电力系统满足用户对电力和电能量的能力。 安全性是指电力系统承受突然发生的扰动,例如突然短路或未预料到的短路或丢失系统元件现象的能力。安全性也称动态可靠性,即在动态条件下电力系统经受住突然扰动,并不简短地向用户提供电力和电能量的能力。 电力系统规模很大,习惯上将电力系统分成若干子系统,可根据这些子系统的功能特点分别评估各子系统的可靠性。可分为: (1)发电系统可靠性:是对统一并网后的全部发电机组按可接受标准及期望数量,满足电力系统负荷电力和电能量需求之能力的度量。 (2)发输电系统可靠性:是由统一并网后运行的发电系统和输电系统综合组成的发输电系统按可接受标准和期望数量向供电点供应电力和电能量之能力。其可靠性包括充裕度和安全性两方面。 (3)输电系统可靠性:是对从电源点输送电力到供电点按可接受标准及期望数量满足供电负荷电力和电能量需求之能力的度量。其可靠性包括充裕度和安全性两方面。 (4)配电系统可靠性:是对供电点到用户,包括配电变电所、高低压配电线路及接户线在内的整个配电系统及设备按可接受标准及期望数量满足供电电力和电能量需求之能力的度量。 (5)发电厂变电所电气主接线可靠性:是对在组成主接线系统的元件(断路器、变压器、隔离开关、母线)可靠性的指标已知和可靠性准则给定的条件下,评估整个主接线系统可靠

计算机专业英语作业: 1、请将视频“什么是电脑硬件”中所述内容用英文表示。 For most people, computers are becoming a part of real life, the film will help you konw how it works. Their interior looks very complicated, but if the decomposition of parts, you will see a simple side of computers , This is《computer hardware in Plaining English 》,you see them, they are coming all shapes and sizes,but its work in some ways. In fact, if you can see their internals of computers, You will find that they all have the basic parts,the haddwares,do large part of the works in the computers.to explan,let’s look at some things you know ,like a house.what a great thing in the house is you have full space to put all the iterms.in fact ,many houses have basements.The basement is a good place to store debris.Basement, the more you can store.The same principle applies to computers.We need not boxes and bicycles, but photos, music, documents and https://www.360docs.net/doc/3c3446766.html,plete this task in the computer hard drive rather than in the basement, a computer hard drive, holds all your files will be used later, like basements, like the larger hard drive, the more things you can store. Basement is not perfect, going to the basement to take the things you need to spend much time, maybe put a cupboard on the ground floor can help you solve this problem, you can quickly get the items you want, although the cabinet can not put too many items, at least you do not always go to the basement, in the computer too, The computer can not quickly access to the data stored in the hard disk, because the computer go a long way to gain access to the hard disk data. In the computer memory (RAM) is like a cupboard, RAM's full name is called [random access memory], which allows the computer to access data more quickly and, of course, it also means that the operation of RAM to make your computer faster , but this cupboard (RAM) has a drawback, the memory will be cleared of stored data When every time you restart, of course, to make the house a variety of household appliances can operate at the appropriate time, you must have an Explorer to help you manage these appliances, if the weather is too hot , you maybe need to open the air conditioner to adjust the temperature, when it is dark, you need to turn on the lights. Computers, too, must have a bit Explorer to ensure that all other parts are functioning properly, the Explorer is the processor (CPU), small size of the processor, like a computer exclusive (in charge), it will send and receive information and to assist the software to complete the work. The faster the processor, the faster execution speed of the computer would be, so, let us revisit. Hard drive, like a basement, it can store the information you need. Memory, like a cupboard, which can increase data access speed. Processor, like the Field Explorer, always able to complete the work that we deliver, but also to ensure the normal operation of the various parts. Next time, when you use the computer, think about plain English in the host computer's computer hardware what happened, the various parts of computer hardware complement each other, to help you do all the things I Common Craft's Lee LeFever, "Computer hardware of Plaining English "The film recorded by me, if you need a higher quality video, or need to use the authorization of the film, please contact me https://www.360docs.net/doc/3c3446766.html, website. 2、请将以下英文翻译为中文。
