摘要
介绍笔者开发的农村电网网损分析系统。该系统包括时变负荷处理数据库和潮流计算、网损仿真计算、运行电压分析、变压器运行状态分析、电网结构分析与改造程序等部分。由于对负荷进行了时变处理和网损仿真计算,结果更加准确。给出了确定高压配电网最佳运行电压的实用方法,并提出了配电变压器 cos■—P平面经济负荷域的新概念。
A new analysis system of power losses for rural network is presented which includes a data bank of real-time loads,power flow analysis,power loss sim- ulation,operating voltage analysis,transformer operation state analysis,and net- work configuration reformation analysis.A practical method of determining the op- timum operating voltages for high voltage distribution network is presented,and a new concept of transformer economic load region on cos(?)-P plane is proposed.
