电力信息采集的计量管理方案摘要：电力企业发展过程中最主要的任务就是建立一套完善的电力信息采集系统，并建立相应的计量管理方案，这能使电力信息采集工作的效率有所提升，进而提高电力企业的经济效益。
本文分析了电力信息采集计量管理方案方面的相关内容，以供借鉴。
关键词：电力企业；信息采集；计量管理方案社会发展进程在加快，进而推动和了电力企业体制的改革，在社会经济发展中电力企业做出了不小的贡献。
电力企业中的电力信息采集系统主要的工作内容就是对电力用户所用电力的相关信息进行采集，并进行处理，是一个实时监控用电信息的系统。
这一系统在正常运行的情况下，能对电力信息进行自动采集、进行电能质量的监测、电力信息自动采集等内容，在电力企业中发挥着重要作用。
为促进电力企业的快速发展，我们要结合电力企业目前的运行状况和用户的用电情况，有效地开展信息采集计量管理工作，推动企业经济效益的提高。
一、电力信息采集系统相关事项分析目前，网络技术、通讯技术以及信息技术被广泛应用在各个领域，促进相关行业的发展，那么在电力企业中运用这些科技技术，能有促进电力企业的发展，在其中多个工作领域都有所应用，比如抄表技术、抄表效率、管理体制等各个方面。
电力信息采集系统主要负责的工作就是对用户用电的信息进行采集，并作出有效的处理，对其进行实时监控。
在这一工作中，电能表、中心处理系统以及用电信息的采集终端都是必要的组成部分。
电力企业还能通过计算机设备以及网络技术等更专业的设备，对企业的营业收费系统进行操控，实现记录、抄表和收费一体化的管理体系。
此外，电力信息采集系统都是要连接采集通信系统来开展工作的，其中电能表和用电信息的采集终端是其通信系统下行的信道，其上行的信道则是主站系统。
电力企业在开展信息采集工作的时候，应该选择具有较高业务能力的人员来进行工作，这样能保证信息采集工作的所有环节都能顺利开展，还能保证采集到的数据信息有一定的完整性和准确性，避免有误差出现为电力企业带来不必要的影响。
基于电力信息采集的计量管理方案
基于电力信息采集的计量管理方案随着科学技术不断创新，人们工作、生活已经离不开种类繁多的电子设备，传统的电力管理模式已经不能满足人们日益增长的对优质电能的需求。
因此电力企业应该改善管理模式，用科学方式采集用户电力信息，通过数据分析精确评判用电需求，合理配给。
文章对电力信息采集系统和电力计量管理进行分析，针对电力信息采集的计量管理现状，提出精确筛选实效性数据，构建科学的自动抄表系统，建立计量数据分析管理平台等方式，希望提升电力信息管理能力。
标签：电力信息采集;计量管理;自动抄表系统前言：随着人们在生产生活中对电能使用量的增加，电力企业也不断的优化自己的营销方式，以便于更好的适应时代发展的需求。
用电信息采集系统是一种智能化的管理，对提高用户的用电质量和电力企业的服务水平都起到了积极的作用。
本文对用电信息采集系统的认识及基于电力信息采集的计量管理方案应用进行了具体阐述。
1电力信息采集系统和电力计量管理分析1.1电力信息采集系统传统的电力信息采集系统主要包含三个部分：主站、通信、执行。
主站层起到监管作用，负责收集用户用电量并监督用户规范用电;通信层在主站层和用户终端设备间搭建信息传输渠道，实时传输用电过程中的一切数据;执行层由主站控制，当用户用电过程出现故障时，通过通信层反馈到主站，主站对执行层下达命令，执行层根据命令进行处理。
通过上述的系统功能，主站设置的计算机设备接收来自通信层、执行层和用户反馈的各类电力信息数据（用电额度、电能功率、损耗情况等）。
电力企业结合自身需要，进行数据筛选并加以分析，最终根据数据了解用户对电能的需求程度，从而做出相应的调整。
综合来看，电力信息采集系统类似于销售行业的市场调研，通过分析客户的潜在消费水平和需求程度，做出针对性方案。
1.2电力计量管理分析电力计量管理主要包含电能管理和设备管理。
电能管理是电力企业针对用户用电量而设置的电能表、计量用电力互感器等设备，以及进行设备维护、配发电力缴费通知单等工作的人员配置等工作计划;设备管理是对电力企业采购并投入使用的相关电力设备（变压器、传感器、计算机等）以及其它固定资产进行跟踪管理，电能监控离不开专业工作人员，因此对人员工作状态的监督管理也隶属于设备管理。

电力大数据建设方案
电力大数据建设方案随着信息技术的高速发展，大数据应用在各行各业中发挥着重要的作用，电力行业也不例外。
电力大数据的建设旨在通过采集、存储、分析和应用电力领域的大量数据，为电力生产与运营提供科学决策支持、提升能源利用效率、改进设备维护和故障预测等方面提供可靠参考。
本文将就电力大数据的建设方案展开讨论，为电力行业提供有益的参考。
一、数据采集电力大数据建设的第一步是数据采集。
数据采集可以通过各种传感器、智能表计、监测设备等手段进行，以收集电力系统各环节的数据。
采集到的数据可以包括供电质量参数、设备工作状态、用电量、电流电压等信息。
为了保证数据的准确性和完整性，可以通过多点采集、分散配置传感器等方式进行。
二、数据存储电力大数据的存储需要采用高效可靠的数据库系统。
可以建立一个分布式数据库系统，将采集到的数据进行分类、整理、存储和备份，以确保数据的安全性和可靠性。
此外，为了提高数据访问的效率，可以采用数据索引和分区等技术手段。
三、数据分析电力大数据的分析是为了从数据中提取有价值的信息和知识。
通过数据分析，可以了解电力系统的运行情况，预测设备故障，优化能源利用，提出合理的节能措施等。
数据分析可以采用机器学习、数据挖掘、统计分析等技术方法，以发现数据中的规律和异常情况。
四、数据应用电力大数据的应用包括数据可视化、智能决策支持、故障预测等方面。
通过数据可视化，可以将大数据转化为直观的图表、报表等形式，便于用户进行数据分析和决策。
智能决策支持可以根据电力大数据提供的信息，为电力系统的管理和运营提供科学的建议和决策。
故障预测则可以通过对大数据的分析，提前发现电力设备的潜在故障风险，提供及时维修和保养的方案。
五、数据安全电力大数据建设方案必须充分考虑数据的安全性。
在数据采集和存储的过程中，可以采用数据加密、用户权限管理等手段，确保数据的机密性和完整性。

电力计量系统数据采集的优化措施
电力计量系统数据采集的优化措施摘要：当前，我国正在经历着改革开放的喜人形势，很多产业都得到了飞速发展，电力行业也得到了空前的发展，并且不断地改变与拓展着。
同时人们物质生活有了很大提高，各类创新电器为更多人提供了很多方便。
特别是，国家电网的覆盖面不断扩大，电力部门是整个快速发展的社会主义市场经济的一个组成部分，覆盖了数百万地区。
基于此，电力部门最迫切的任务就是要采集用户数据并针对不同用户实际需要对电网分布进行科学规范，确保电力用户基本用电需要。
关键词：电力；信息采集系统；电力计量；运用引言：伴随着软件功能的不断增强，该系统在日常运行中变得更加多样化，既需要在有序用电过程中完成多种主站工作，又需要在正常计划检修过程中进行负荷监测，读取每月商业电表并对负控数据进行异常分析，追踪过剩电量用户负荷情况。
同时也配合附加负控制指标，这样既可以增加负荷与容量分析及终端用户控制覆盖率又可以增加系统的利用率。
1电力用电信息采集系统产生的背景伴随着我国改革开放的不断推进，社会各行各业得到了迅速的发展。
中国电网的覆盖范围也在不断扩大，中国电网的用户规模也变得非常庞大。
同时，也产生了愈来愈多在原有条件下难以克服的问题与矛盾。
电力行业与用户间的冲突及问题逐步累积，将逐步降低电力行业运行效率的同时，还将破坏电力行业自身良好的企业形象，妨碍电力企业树立良好声誉。
电力信息收集系统也是如此。
利用这些系统可对以上企业和客户间的冲突提供一个有效解决方案。
这些系统能够采集较以前更为丰富的有关为终端用户提供电力的数据，还能够更为精确地计算所需的电力。
作为这种信息收集系统的结果，中国的电网公司将开始建立一个更全面的电力信息收集系统，同时增强公司在电力行业实施新的业务结构的能力，让供电业务管理更智能、更高级，推动供电网络全面覆盖。
2电力计量系统数据采集的优化措施2.1远程操作技术、自动化抄表技术的应用科技的发展使得电力企业信息采集系统智能化程度越来越高，并加入了该系统蕴含的各项功能。

北京电力电缆公司电缆数据采集及数据管理系统方案建议书北京恒华伟业科技发展有限公司目录第一章系统概述1.1 系统建设内容本系统包括的建设内容包括：(一)电缆沟道地理位置测量本期项目测量的主要空间要素包括电缆公司管辖范围内的隧道、管、井的平面位置、高程、埋深等；同时调查相关资源的属性信息，记录电缆在隧道、管井中的敷设位置。
(二)搭建图形数据库图形数据是本系统赖以运行的基础，因此搭建图形数据库是本系统建设的一项重要工作。
数据库建库工作包括三项：1)二维矢量地图的处理和入库二维矢量数据主要包括：行政区划、道路、水系、绿地、地物等。
2)卫星影像数据处理及入库对卫星影像数据的处理工作主要是图幅的拼接，拼接完成后将其导入图形数据库。
3)电缆沟道的矢量化及入库工作本项目中，电缆沟道矢量化的方式主要包括两种，一种是实地测量，另外一种是根据已有设计图纸人工矢量化，矢量化完成后将其导入图形数据库。
(三)搭建电缆图形管理子系统需要搭建电缆图形管理系统，以实现各类电缆沟道设备及设施的矢量化绘制及管理功能、各类专题图绘制及管理功能、电缆沟道综合信息查询功能等。
需要绘制的电缆设备及设施包括：电缆、刀闸、电缆分支箱、避雷器、压力箱、接地箱、电缆接头、电力管、电力沟、沟槽、电力井、通风亭（通风孔）、变电站、终端站、电缆小间等。
需要绘制的专题图包括：沟道断面图、管道断面图、沟道纵断面图、电缆井纵断面图、沟道系统图；电缆沟道综合信息查询，主要实现电缆基本信息、沟道基本信息、沟道使用信息和沟道专题图等信息的综合展示，为电缆管理人员提供全面的信息，作为电缆管理人员制定管理决策的依据。
(四)搭建电缆WebGIS查询子系统WebGIS查询子系统依托IE运行，客户端无需安装专用软件，只要安装了Internet Explorer即可使用本系统的功能，而Internet Explorer已经内置于Windwos操作系统内，因此WebGIS查询子系统是一个完全免安装的系统。
通过Web查询子系统，可以查询到各种电缆信息、浏览电缆图及各类专题图，但是无法对图形进行修改，搭建WebGIS查询子系统的目的就是满足数据查询类用户的要求，以降低系统的维护难度和维护工作量。
(五)实现与相关系统的接口本系统需要实现与电缆生产MIS系统和光纤测温系统的接口。
开发与电缆生产MIS系统接口目的是从MIS系统中提取设备台帐信息，以避免信息的重复录入、避免形成新的信息孤岛。
与光纤测温系统接口的目的是从光纤测温系统中提取采集到的当前及历史数据，并在GIS图上展示采集到的当前数据，采集到的历史数据采用和光纤测温系统相同的展示方式，这样可以简化电缆管理人员的日常工作，无需在两个系统间频繁地切换；同时，也实现了图形化的电缆温度监控，使监控更加直观便捷。

2.2.1 系统网络结构GIS应用工作站ArcGIS Engine（若干）Web查询客户端Internet Explorer（若干）在该方案中，所有数据存储于数据服务器上，这些数据包括矢量化的GIS数据、影像数据、各种实景图片数据、所有业务数据等；所有需要发布给最终用户使用的软件都部署在Web Server上，C/S架构系统的最终发布的软件也部署在该服务器上，需要安装时从该服务器进行下载安装，软件发生更新时，只需要将最新的软件发布到该服务器上，各已安装客户端自动下载更新。
2.2.1.1 数据服务器本系统中，数据服务器上需要存放电缆GIS系统的全部数据、生产MIS系统和光纤测温系统的部分数据。
本系统中，服务器上存储着所有矢量图形（背景地图和电网图）和影像图形（卫星影像和航空影像）数据，数据量接近100GB，而客户端应用需要频繁地对这100GB的数据进行访问；因此，本系统要求服务器配备优良的磁盘I/O系统，建议在条件允许的情况下选择光纤磁盘和光纤磁盘阵列，或者尽量选择高速磁盘和高速数据总线。
其次，由于GIS 服务器系统在检索空间数据时存在大量的空间计算，因此要求服务器要配备高主频的CPU，建议配置Xeron 2.0G级别以上的CPU。
最后，为提高数据库管理软件的运行效率，需要为其准备足够的内存高速缓冲，建议内存总容量不低于4GB。
另外，该服务器上没有空间图形显示的需求，因此对显卡没有特殊要求，普通显卡即可。
本系统采用Oracle 9i作为数据库管理系统，服务器利用电缆公司现有的硬件资源即可。
2.2.1.2 Web服务器在本系统中，由于WebGIS子系统采用了B/S架构，同时由于需要运行WebGIS服务器端应用，因此需要设置Web Server和Application Server，鉴于本系统的具体情况，设计时决定将这两种类型的服务运行于相同的服务器上，这样可以在保证系统性能要求的情况下，降低系统建设成本和管理维护的复杂程度。
该服务器上需要运行Web Server软件和WebGIS Server软件，GIS数据的操作多数都在内存中进行，存在大量的空间运算；文件I/O主要体现在Web页面文件及图片文件的访问上。
因此，该服务器要求配置较高主频的CPU，建议配置Xeron 2.0G级别的CPU，服务器内存不少于1GB，磁盘采用常规的SCSI接口形式的即可，磁盘阵列也可采用SCSI 接口。
另外，该服务器上没有空间图形显示的需求，因此对显卡没有特殊要求，普通显卡即可。
该服务器利用已有硬件资源，无需重新购买，接口软件也运行于该服务器上。
另外，为降低系统建设投资，该服务器同时作为数据备份服务器。
如果要做数据的永久备份，需要购置磁带机和磁带。
Web Server软件可以采用BEA公司的Web Logic或IBM公司的Web Sphere或Apache Tomcat。
WebGIS Application Server选用ESRI的ArcIMS 9。
2.2.1.3 外部系统的接入本期项目主要考虑电缆测温系统和生产MIS系统的接入。
接口软件运行于Web服务器上，该软件具备服务器失效时不丢失数据的功能，服务器恢复正常后，可以从上一次的最后同步点上继续同步数据。
2.2.1.4 系统客户端系统客户端分为三类，图形编辑/GIS应用类客户端，图形打印类客户端，Web查询类客户端，这些客户端计算机可利用已有资源。
图形编辑/GIS应用类客户端对计算机性能的要求较高，尽量配备高主频的CPU、512M 以上的内存、中档以上显卡（128M以上缓存）。
图形打印类客户端对计算机的要求相对低一些，但最好配备512M内存、较快的CPU、中档显卡（128M缓存）。
同时需要为该类客户端配置打印机，对打印机没有特殊要求；但如果要打印大幅面图纸，如A0图纸，则需要另外配置绘图仪。
Web查询类客户端对计算机要求很低，普通商用PC机即可。
2.2.1.5 网络要求多数电力企业内部办公网络都具备了100M带宽，因此系统对网络带宽没有特殊要求。
但是要求有良好的网络安全管理措施，如统一的防病毒措施、统一的网络恶意攻击防御策略等。
2.2.2 系统逻辑结构登录控制从逻辑上讲，系统由三大体系组成：技术体系、功能体系和保障体系。
技术体系包括数据层、模型层、组件/中间件层和应用服务层；功能体系包括表示层和接口层，表示层既最终用户可使用的功能最大集合；保障体系指确保系统安全、稳定、可靠、高效运行的体系，包括技术的和管理的保障两大方面，技术保障体系包括：系统安全体系、系统维护机制和日常管理措施等，这些内容将在后续章节中陆续介绍。
数据层是管理信息系统的核心层，其它所有层都直接或间接地受该层制约。
数据层主要实现数据的管理和提供各种数据访问服务，数据层管理的数据包括：GIS矢量图形数据、影像数据、CAD文件数据和现场实景图片等。
2.2.2.2 模型层这是一个抽象层，是系统的抽象展现。
模型设计是现代软件设计的重要组成部分，是软件开发技术经过30余年发展的结果，模型驱动的软件开发是现代软件工程的最新理念。
模型层包括：设备编码模型、设备对象模型、电网模型、数据交换模型、电网分析模型、电网拓扑模型等，需要说明的是，这些模型并不是相互孤立的，模型之间只是相对独立但又相互联系。
所有这些模型的集合就是系统的整体模型，系统的实现建立在该模型上。
2.2.2.3 组件/中间件层组件层是系统开发的基础，各功能模块均直接或间接地通过组件实现。
本系统使用到的组件包括：J2EE组件、ArcGIS Engine的COM组件和ArcIMS的WebGIS组件等。
中间件层是系统后台服务的组成部分，本系统中用到的中间件包括ArcSDE（空间数据引擎）、权限控制引擎等。
2.2.2.4 应用服务层应用服务层是系统实际业务逻辑的处理层，是前端用户实际使用到的功能的后台实现。
本系统中的应用服务是WebGIS功能服务，即ArcIMS Application Server。
表示层是系统和用户间的交互层，或者说是人机交互界面层。
该层是系统具体功能的实际展现，也就是用户能够使用的具体功能。
根据实际业务逻辑构成，我们将系统划分为：电缆GIS子系统、WebGIS查询子系统以及和外部系统的接口。
