摘　　要：苏州南部电网的电力受季节变化潮流分布影响较大,在部分方式下断面存在"卡脖子"的现象,拟通过加装500kV统一潮流控制器(UPFC)来解决该问题。介绍了UPFC的应用现状,对UPFC在苏州南部500 kV电网的需求进行了分析、计算,论证了UPFC装置在潮流控制以及电压支撑方面所起的作用,结果表明,加装UPFC后,有效解决了该电网线路的输电瓶颈及直流双极闭锁后大面积的限负荷问题。Because of seasons,there will be some problems in Suzhou Southern grid,such as limited transfer capacities of power importedchannels,unbalanced power flow distributions and so on,which explains the necessity to install the500kV unified power flow controller(UPFC)in Suzhou Southern grid.Introduction was made to the application status of UPFC.This paper carried out analysis and calculationfor Suzhou Southern500kV grid and discussed the functions of UPFC device in power flow control and voltage support.The results showthat after the UPFC device was added,the transmission bottleneck of this grid is effectively solved,as well as a large area of limited loadproblem after direct current twin pole shutting.
