摘要
有源电力补偿系统在动态补偿过程中需要快速、准确地检测出三相系统中的谐波电流、不对称电流以及无功电流。针对三相电源出现畸变或不对称问题,分析了三相不对称系统中的同步检测法和三相四线制系统中的i p-i q检测法,提出了以同步检测法为基础、融合i p-i q法的一种新型检测方法,仿真结果表明该方法能够准确地检测谐波、无功及不对称电流。
Active power compensation system in the process of dynamic compensation need to be fast with accurate detection of harmonic currents in three-phase system, the asymmetry current and reactive current. The synchronous detection method in unbalanced three-phase system and three-phase four-line system ip-iq detection method was introduced. A new detection method was proposed based on ip-iq detection method and three-phase power supply distortion or asymmetric. The simulation results show that the method can detect the harmonic, reactive and asymmetrical current more accurately.
