摘要
电力有源滤波器是一种新型谐波抑制装置.对于不对称三相电路,可同时抑制其中的基波负序电流.为此需准确检测出谐波与基波负序电流之和.文中对一种基于三相电路瞬时无功功率理论的检测方法进行了理论分析、仿真及实验.结果表明。
Active power filter is a type of novel harmonic suppression device. When used in unbalanced three phase circuits, it can compensate harmonic and negative sequence currents simultaneously. For this puropse, the sum of harmonic and furdamental negative sequence currents should be detected precisely. A real time detecting method for harmonic and fundamental negative sequence currents in unbalanced three phase circuits was theoretically analyzed, the simulation and experiment were done. The results made it evident that harmonic and fundamental negative sequence currents could be detected precisely by using this method.
