Now mainly on intelligent technology theoretical basis, technical superiority and in electrical engineering and automation control in the process of practical application in are analyzed and discussed.
[Key words] electrical engineering; intelligent technology; application Introduction: since the reform and opening up, with China's infrastructure continues to improve and further, electric power industry has also been rapid development, the development of electrical engineering is particularly prominent. Due to early electrical automation control some more or less defects, and the introduction of intelligent technology, not only to make up the defects early automation control technology of electrical engineering and it also to a certain extent, promoted the development of electrical engineering. Intelligent technology is a kind of the artificial intelligence theory into computer technology in the new high-tech, it in electrical engineering and automatic control in the field of application is in the initial stage and great development space.
1 the theoretical basis of the application of Intelligent Technology Intelligent technology in the use of process based on the theory of covering the control, linguistics, information science, biology and medicine, and many other disciplines, it is relatively strong. Main study of this technology is how to let the machine with artificial intelligence, and have certain high risk independently, ability of the high degree of difficulty. In order to ensure the intelligent technology in the
use of in the process of practical, by combining computer technology to the operation of the experiment, the timeliness of research and development of intelligent machine and effectiveness.
Research and development of intelligent technology is the main research content of the entire electrical automation and control industry, including electrical and electronic technology, information collection and processing, its application in electrical engineering and automation control early examples that, has a strong adaptability and practicability. As high-end branches in today's computer technology, intelligent technology is gradually being applied to electrical engineering automation control, a large number of facts show that intelligent technology in electrical engineering automation control process has made certain effect. Application of intelligent technology in electrical engineering, not only improve the electrical automation control in the process of work Efficiency, but also reduce the project investment cost, reduce working pressure of the control personnel, realize the human resources rational allocation of 0.2, the intelligent characteristics of high precision and high efficiency.In electrical engineering, automation control, precision and efficiency is crucial, intelligent technology using high speed CPU chip, RISC chip, the multi CPU control system, makes the electrical engineering precision and efficiency is more and more high.
2 Process of composite and multi axis.
Intelligent technology, the main purpose is to reduce the process and auxiliary time. Application of intelligent technology in electrical engineering is a multi axis and multi system control function of the direction of development. The data and interpretation of the data, the exchange of information is no longer limited to the text and language education, there are more graphics, images, animation and other visual information.
3 intelligent technology in the use of the advantages of the process Intelligent technology in electrical automation control in the process of application, the main form is to make the controller to realize the intelligent, intelligent controller in electrical automatic control advantages than traditional controller bigger, its main
advantages are the following:
3.1 no need to set up a control model
In process automation using traditional controller to control, often because of the control object to have a more complex dynamic equation, so there is no way to accurately grasp the, this will lead to in the design of the object model appeared a lot of cannot be underestimated, cannot predict the objective factors, such as parameters change. If we cannot grasp such factors, design model is not possible to precisely and eventual automation control of the actual working efficiency in a certain extent will be reduced. Intelligent controller eliminates the need for controlled object model design, so it from the source to avoid the emergence of those uncontrollable factors The precision coefficient of the automatic controller is improved.
3.2 to facilitate the adjustment of the electrical system control
Another advantage of the intelligent controller is that it can be through changes in robustness and response time and down time of the system, the degree of control to adjust at any time, so that its own performance can be effectively improved and the automatic control of work are the basic guarantee. Thus, in any case, intelligent controller to than the mediation of the traditional automatic controller control function has more advantages, is more suitable for use in the actual work of electrical engineering and automation. In addition, intelligent controller and a good, that is in the regulation and control of the process of electrical equipment, as long as rely on the data changes It can adjust itself does not require the presence of professional and technical personnel. In a certain extent it can remote control, the realization of the project of electrical control system for an unmanned automatic control, which for the development of electrical engineering and automation control has a great influence.
3.3 to Intelligent controller has strong consistency, mainly reflected in dealing with the problem of different data, even if the input data is very strange can also obtain higher estimates, realize the automation control of the relevant requirements. Effect of different control is being controlled by the different objects to decide, although
intelligent controller in the control of some of the objects and no immediate action and its control effect is still very good, but this is not absolute, the change of control object may lead to the effect of the control is not up to the expected results. So in the design of the automatic control system, be sure to implement the specific design principles for different Object must be of a specific analysis of the specific circumstances, according to the actual situation of the object of comprehensive analysis, the requirements for the control must be strict scrutiny. If intelligent controller in poor using effect in the process, not the intelligence of controlling technology of blind to negative, we must carefully investigation and analysis to each link of the project.
4 the application of intelligent technology in electric automation control

4.2 optimization design
Required to complete the experience and knowledge in electrical engineering and automation control process, often related to electrical equipment design, and the design process is very complicated, it requires not only the design of magnetic and electrical circuit subject to have enough understanding and appropriate use to design work, and it to the design personnel work experience also has relatively high requirements. The traditional design way is the combination of manual design, the
project compliance rate is low, the modification is difficult, and now the scheme design is the use of CAD technology and computer aided software to complete, not only reduce the design time and design Out of both quality and performance is relatively good. Genetic algorithm is optimization design of intelligent application technology one of the concrete forms, it has very strong practical and advanced, its use in a certain extent of design were optimized. Optimum design. Design of electrical equipment is a complicated work it is not only to the application circuit, electromagnetic field, electrical appliances and other disciplines of knowledge, but also the use of a large number of empirical knowledge of design. The traditional product design is using simple experimental method and based on experience with manual of. Therefore difficult to obtain optimal solution. With the development of computer technology.

Therefore, electrical products artificial intelligence optimization design most of the use of this method and its improved method.
4.3 fault diagnosis
In the running process of the system of electrical engineering and electrical equipment occurred failures are inevitable, and before the failure will a series and fault itself there signs of connection, intelligent technology, you can the comprehensive, accurate diagnosis. By in the transformer in electrical equipment has very important role, therefore electrical equipment monitors the running status of the extra attention, often the were not timing detection, maintenance, but it is not able to completely avoid the emergence of electrical fault, in order to in a timely manner to the fault diagnosis, the electrical fault caused the losses to a minimum, the intelligent technology is undoubtedly The best choice.
In the use of intelligent technology of transformer fault diagnosis, the main
diagnostic methods is through of transformer oil leakage of gas decomposition analysis, to quickly find the approximate range of the fault of transformer, and then to gradually narrow the scope to find the specific location of the fault and its maintenance. This not only accelerates the of fault diagnosis and maintenance rate, and it also can avoid the fault of electrical equipment caused by damage, the electrical equipment operation and economic benefit in a certain extent can be improved. The application of intelligent technology in electrical automation control.
4.4 fuzzy logic and control Fuzzy set is dynamic.
The application of electrical engineering and automation control system contains a lot of fuzzy controller, which can effectively replace the ordinary controller, and can be better used in other aspects. The fuzzy controller in the initial research is mainly applied in all kinds of digital transmission system. Fuzzy logic control in the application of M and s types, including in the speed control is mainly used M type controller. Two different controllers is a rule base, has a more specific fuzzy rules M type controller is mainly composed of a fuzzy inference machine, knowledge base and anti fuzzification, which function is to achieve Quantified variables, measurement and fuzzy, in operation to be applied to very much the function form. Inference engine is fuzzy controller is the key part and can mimic human reasoning to make decisions and reasoning. Knowledge base is the main language control and data libraries, previously used in, the knowledge and experience on the control and application of the target, through this way to the construction of operation controller, to control the action at the same time. In the process of model construction, the fuzzy controller and neural network inference engine were used together, so as to better realize intelligent operation. 4.5PLC technology application. With the development of science and technology, the electric power production requirements are also getting higher and higher, some large power enterprises in the auxiliary system, the relay controller is replaced by PLC technology. With the PLC system can realize the auxiliary system a process control, and to coordinate the production of the whole enterprise. Application of PLC technology in the power supply system, the effective realization of the automatic switching and physical components is replaced
by soft relay, which greatly improves the safety and reliability of the power supply system. 4. Summary

Page1 Electrical Energy Transmission（电能输送） From reference 1 Growing populations and industrializing countries create huge needs for electrical energy. Unfortunately, electricity is not always used in the same place that it is produced, meaning long-distance transmission lines and distribution systems are necessary. But transmitting electricity over distance and via networks involves energy loss. So, with growing demand comes the need to minimize this loss to achieve two main goals: reduce resource consumption while delivering more power to users. Reducing consumption can be done in at least two ways: deliver electrical energy more efficiently and change consumer habits. Transmission and distribution of electrical energy require cables and power transformers, which create three types of energy loss: the Joule effect, where energy is lost as heat in the conductor (a copper wire, for example); magnetic losses, where energy dissipates into a magnetic field; the dielectric effect, where energy is absorbed in the insulating material. The Joule effect in transmission cables accounts for losses of about 2.5 % while the losses in transformers range between 1 % and 2 % (depending on the type and ratings of the transformer). So, saving just 1 % on the electrical energy produced by a power plant of 1 000 megawatts means transmitting 10 MW more to consumers, which is far from negligible: with the same energy we can supply 1 000 - 2 000 more homes. Changing consumer habits involves awareness-raising programmers, often undertaken by governments or activist groups. Simple things, such as turning off lights in unoccupied rooms, or switching off the television at night (not just putting it into standby mode), or setting tasks such as laundry for non-peak hours are but a few examples among the myriad of possibilities. On the energy production side, building more efficient transmission and

Programmable designed for electro-pneumatic systems controller John F.Wakerly This project deals with the study of electro-pneumatic systems and the programmable controller that provides an effective and easy way to control the sequence of the pneumatic actuators movement and the states of pneumatic system. The project of a specific controller for pneumatic applications join the study of automation design and the control processing of pneumatic systems with the electronic design based on microcontrollers to implement the resources of the controller. 1. Introduction The automation systems that use electro-pneumatic technology are formed mainly by three kinds of elements: actuators or motors, sensors or buttons and control elements like valves. Nowadays, most of the control elements used to execute the logic of the system were substituted by the Programmable Logic Controller (PLC). Sensors and switches are plugged as inputs and the direct control valves for the actuators are plugged as outputs. An internal program executes all the logic necessary to the sequence of the movements, simulates other components like counter, timer and control the status of the system. With the use of the PLC, the project wins agility, because it is possible to create and simulate the system as many times as needed. Therefore, time can be saved, risk of mistakes reduced and complexity can be increased using the same elements. A conventional PLC, that is possible to find on the market from many companies, offers many resources to control not only pneumatic systems, but all kinds of system that uses electrical components. The PLC can be very versatile and robust to be applied in many kinds of application in the industry or even security system and automation of buildings.

英语原文 NUMERICAL CONTROL Numerical control(N/C)is a form of programmable automation in which the processing equipment is controlled by means of numbers, letters, and other symbols, The numbers, letters, and symbols are coded in an appropriate format to define a program of instructions for a particular work part or job. When the job changes, the program of instructions is changed. The capability to change the program is what makes N/C suitable for low-and medium-volume production. It is much easier to write programs than to make major alterations of the processing equipment. There are two basic types of numerically controlled machine tools：point—to—point and continuous—path(also called contouring).Point—to—point machines use unsynchronized motors, with the result that the position of the machining head Can be assured only upon completion of a movement, or while only one motor is running. Machines of this type are principally used for straight—line cuts or for drilling or boring. The N/C system consists of the following components：data input, the tape reader with the control unit, feedback devices, and the metal—cutting machine tool or other type of N/C equipment. Data input, also called “man—to—control link”,may be provided to the machine tool manually, or entirely by automatic means. Manual methods when used as the sole source of input data are restricted to a relatively small number of inputs. Examples of manually operated devices are keyboard dials, pushbuttons, switches, or thumbwheel selectors. These are located on a console near the machine. Dials ale analog devices usually connected to a syn-chro-type resolver or potentiometer. In most cases, pushbuttons, switches, and other similar types of selectors are digital input devices. Manual input requires that the operator set the controls for each operation. It is a slow and tedious process and is seldom justified except in elementary machining applications or in special cases. In practically all cases, information is automatically supplied to the control unit and the machine tool by cards, punched tapes, or by magnetic tape. Eight—channel punched paper tape is the most commonly used form of data input for conventional N/C systems. The coded instructions on the tape consist of sections of punched holes called blocks. Each block represents a machine function, a machining operation, or a combination of the two. The entire N/C program on a tape is made up of an accumulation of these successive data blocks. Programs resulting in long tapes all wound on reels like motion-picture film. Programs on relatively short tapes may be continuously repeated by joining the two ends of the tape to form a loop. Once installed, the tape is used again and again without further handling. In this case, the operator simply loads and

What is Hydraulic? A complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, no parts and hydraulic oil. The role of dynamic components of the original motive fluid into mechanical energy to the pressure that the hydraulic system of pumps, it is to power the entire hydraulic system. The structure of the form of hydraulic pump gears are generally pump, vane pump and piston pump. Implementation of components (such as hydraulic cylinders and hydraulic motors) which is the pressure of the liquid can be converted to mechanical energy to drive the load for a straight line reciprocating movement or rotational movement. Control components (that is, the various hydraulic valves) in the hydraulic system to control and regulate the pressure of liquid, flow rate and direction. According to the different control functions, hydraulic valves can be divided into the village of force control valve, flow control valves and directional control valve. Pressure control valves are divided into benefits flow valve (safety valve), pressure relief valve, sequence valve, pressure relays, etc.; flow control valves including throttle, adjusting the valves, flow diversion valve sets, etc.; directional control valve includes a one-way valve , one-way fluid control valve, shuttle valve, valve and so on. Under the control of different ways, can be divided into the hydraulic valve control switch valve, control valve and set the value of the ratio control valve. Auxiliary components, including fuel tanks, oil filters, tubing and pipe joints, seals, pressure gauge, oil level, such as oil dollars. Hydraulic oil in the hydraulic system is the work of the energy transfer medium, there are a variety of mineral oil, emulsion oil hydraulic molding Hop categories. Hydraulic principle It consists of two cylinders of different sizes and composition of fluid in the fluid full of water or oil. Water is called "hydraulic press"; the said oil-filled "hydraulic machine." Each of the two liquid a sliding piston, if the increase in the small piston on the pressure of a certain value, according to Pascal's law, small piston to the pressure of the pressure through the liquid passed to the large piston, piston top will go a long way to go. Based cross-sectional area of the small piston is S1, plus a small piston in the downward pressure on the F1. Thus, a small piston on the liquid pressure to P = F1/SI,Can be the same size in all directions to the transmission of liquid. "By the large piston is also equivalent to the inevitable pressure P. If the large piston is the cross-sectional area S2, the pressure P on the piston in the upward pressure generated F2 = PxS2 Cross-sectional area is a small multiple of the piston cross-sectional area. From the type known to add in a small piston of a smaller force, the piston will be in great force, for which the hydraulic machine used to suppress plywood, oil, extract heavy objects, such as forging steel.
