摘要
为了降低同煤电网损耗,提高经济效益,使整个供电电网运行在经济、合理的状态中,节约电能,降低电力成本,利用PSASP电力系统综合仿真程序对同煤电网进行潮流分析,根据同煤电网实际运行中的典型负荷曲线与电容投切、变压器分接头调节情况进行了网损耗分析计算,给出了变电站高损耗变压器的改造方案及电网的改造方案。分析结果表明,电网优化后电网总网损降低了4.01%,证明了改造方案的可行性。
In order to reduce grid loss of Datong Colliery,improve economic efficiency,and enable the whole power grid to operate in the economic,rational state to save electric energy and reduce electric power cost,PSASP electric power system integrated simulation program is used to analyze power flow of Datong Colliery,grid loss is calculated according to the typical load curve and capacitor switching in actual operation of coal power grid,and the adjustment of transformer tap,then modification scheme of transformer loss and grid is given.The analysis results show that grid loss reduces 4.01% after its optimization and prove the feasibility of modification scheme
