配电网网损研究现状分析及网损计算
摘要配电网网损是表征供用电企业经济效益和技术管理水平的综合性技术经济指标,也是国家贯彻节能方针考核供用电部门的一项重要指标。当前,电网管理正逐步引入市场竞争机制,发电单位及电力公司公开、公平地竞争选择电源,电力用户群体已经基本固定,如何提高经济效益,降低损耗是关系到电力公司生存与发展的重要课题,因而进行配电网网损损计算与分析,既具有理论意义,又具有很大的实用价值,可为配电网经济运行提供有力的保障。
本论文基于对山西省大同县目前配电网的研究,首先介绍了国内外对于配电网网络损耗的研究现状和发展趋势,其次对现今常用的几种计算和分析配电网网损的主要方法进行了说明,阐述了几种典型电网理论线损的方法和步骤,然后通过对比各方法的优缺点和适用范围,并结合山西省大同县电网实际情况,采取适合本网的理论线损计算方法,通过对2009年截取的三个工作日的电网负荷实测记录分别采取潮流法、等值电阻法以及近似算法进行了网损计算,,并提出降损改进办法。

Loss analysis studying and Loss
Calculation for Power work
Abstract
work loss is a power supply enterprise economic benefits and technical management level of technical and economic indexes, is prehensive national energy policy implementation evaluation and utilization of the department is an important index. Current, power grid management gradually introduce the petition mechanism, generating unit and the pany open, petition, power users choose power has been basically fixed, how to improve the economic benefit and reduce loss is related to the survival and development of the electric pany, and important subject for work loss damage calculation and analysis, which has great theoretical significance and practical value, economic operation for work can provide a powerful guarantee.
This paper, based on the current distribution of shanxi, datong county first introduced at home and abroad for work loss research situation and development trend of nowadays, secondly, several calculation and analysis of the main method of work loss, expounds several work theory, methods and steps of the loss, and paring the advantages and disadvantages of each method and the applicable scope, bined with actual situation in Shanxi Province, datong county grid for this theoretical calculation method, through to the loss of the 2009 intercepted three working days of the electric load test records, equivalent to tide respectively resistance method and the approximate algorith
