摘要
针对大型供、配电站需要在滤除谐波的同时进行无功功率补偿的工程要求,改进了目前常用的并联混合型有源电力滤波器的拓扑结构,提出一种新颖的谐波注入式电路,进一步减小了有源滤波部分的容量,达到了工程应用的目的。详细介绍了该系统的滤波原理、控制器结构和大功率逆变器的实现。该装置已在 220KV 变电站挂网试运行,运行结果表明该装置滤波效果较好、可靠性高。而且这种 HAPF 的性能价格比较高,因而具有良好的工程推广应用价值。
Compared with hybrid power filter with a loplogical structure and widely used at present, a novel high capacity hybrid power filter based on injection circuit is proposed to meet the requirements of harmonic elimination and reactive power compensation in substation. Principally, controller and high power converter are discussed. The operation results with this new filter installed in a 220kV substation prove that it is good in performances and in harmonics elimination, reactive power compensation and reliability. In addition, this facility is in favor of application due to its good cost performance.
