摘要
针对变电站需要在滤除谐波的同时进行无功补偿的工程要求,对目前常用的并联混合型有源滤波器的拓扑结构进行了改进,提出了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变电站挂网运行,运行结果表明,该装置滤波效果较好、可靠性高,而且性能价格比较高,因而具有较高的工程推广应用价值。
Compared with hybrid power filter widely used at present,a novel high capacity shunt hybrid power filter based on injection circuit is proposed to meet the requirements of harmonic elimination and reactive power compensation in substation.The principle, controller and high power converter are discussed. The operation results with this new filter installed in a 220 kV substation prove its good performances of harmonics elimination, reactive power compensation and reliability. In addition, this facility is in favor of application due to its good performance.
