摘　　要：湖南省500 kV某变电站在2017年上半年完成两台总容量为120 Mvar (正常运行容量为100 Mvar)的直流融冰型静止同步补偿器安装。其投运后将成为湖南电网首台静止同步补偿方式的大容量无功补偿设备。本文采用Matlab/Simulink对H桥级联型STATCOM进行建模,对其无功补偿特性、系统组成等方面进行分析,对其补偿效果进行了研究和验证。其对湘潭换流站的建设以及特高压入湘后的稳定性研究有重要意义。In the first half of 2017,two DC ice-melting static synchronous compensators with a total capacity of 120 Mvar(a normal operating capacity of 100 Mvar)are completed in a 500 kV substation in Hunan.After it is put into operation,it will become the first static synchronous compensation equipment of Hunan power network.In this paper,the H bridge cascade STATCOM is modeled by Matlab/Simulink,and its reactive power compensation characteristics and system composition are analyzed,and its compensation effect is studied and verified.It is of great significance to the construction of Xiangtan converter station and the study of the stability of Xiangtan converter station after entering Hunan under UHV.
