摘要
以工矿企业35 kV/6 kV变电站为研究应用背景,提出一种应用于大功率STATCOM的谐波与无功综合电流补偿控制策略。在治理谐波方面,采用了一种基于多个n次谐波同步旋转变换的谐波低频补偿技术,能够对低次谐波进行补偿控制;在基波无功的动态补偿方面,采用前馈闭环解耦控制,能够精确、动态地补偿基波无功电流。从而实现了谐波和无功的综合补偿。
This paper develops high-power STATCOM devices which can make reactive power and harmonic comprehensive current compensation for 35 kV/6 kV substation in industrial and mining enterprises. In harmonic management aspects, harmonic compensation technology based on low frequency control is proposed. This technology based on multiple n time harmonic synchronous rotating transformations can make key compensation of lower harmonic. In dynamic reactive compensation, closed-loop decoupling control of fundamental reactive and active current is prorposed,which can compensate reactive power accurately, dynamically. So reactive power and harmonic current comprehensive compensation is realized.
