摘　　要：基于链节H桥单元模块,将多电平调制技术应用于链式静止同步补偿器(STATCOM)系统中,并对H桥模块关键参数进行分析与设计。同时,结合反馈解耦控制理论与APF控制技术,研究一种适合于煤矿井下无功和谐波综合电流质量补偿系统,对井下电网电能质量进行优化。最后,搭建1140V链式STATCOM试验平台,实验证明STATCOM装置能够实现无功和谐波的综合补偿,补偿效果较好。Based on cascaded H-bridge unit module, the multilevel modulation technology is applied to system of STATCOM, and the key parameters of H-bridge module are analyzed and designed in this paper.Meanwhile, this pa-per puts traditional feedback decoupling control theory and APF control technology into STATCOM, and researches a kind of compensation system which is suitable for reactive power in the coal mine and harmonic compound current quality to optimize the grid power quality.Under this theory and technique, test prototype of 1140V cascaded STAT-COM is built.Test shows the STATCOM device can realize the compound compensation for reactive power and har-monics, and has a good compensation effect.
