基于电力系统运行模拟的江苏输电网规划方案网损实证分析

Empirical Analysis on Transmission Loss of Jiangsu Power Grid Planning Based on Power System Operation Simulation

网损计算与分析是电网运行分析的一项重要工作,在江苏电网规划和发展的过程中,对其网损进行实证分析,具有十分重要的现实意义。文中基于直流潮流的网损计算方法,运用电力系统运行模拟软件系统(GOPT),对江苏输电网规划方案网损进行了实证分析,以2012年和2015年为水平年,并针对不同的特高压建成方案,对江苏电网不同区域、不同线路类型进行了网损统计和对比分析。

The calculation and analysis of transmission loss is an important part of the analysis of power grid operation.And it is of great significance to make an empirical analysis on transmission loss of Jiangsu power grid during the process of its planning and development.According to the transmission loss calculation methods using DC power flow,this paper uses the power system operation simulation software platform (GOPT),and presents an empirical analysis of the transmission loss of Jiangsu power grid.The years of 2012 and 201 5 are taken as level years.Considering different schemes of high voltage transmission planning,this paper carries out the network loss satatistics and empirical analysis based on different regions and different line types of Jiangsu power grid.
