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500 kV 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。

Abstract: Because of seasons, there will be some problems in Suzhou Southern grid, such as limited transfer capacities of power imported channels, unbalanced power flow distributions and so on, which explains the necessity to install the 500 kV unified power flow controller (UPFC) in Suzhou Southern grid. Introduction was made to the application status of UPFC. This paper carried out analysis and calculation for Suzhou Southern 500 kV grid and discussed the functions of UPFC device in power flow control and voltage support. The results show that after the UPFC device was added, the transmission bottleneck of this grid is effectively solved, as well as a large area of limited load problem after direct current twin pole shutting.
Key words: unified power flow controller (UPFC); Suzhou Southern grid; power flow control; voltage support
