摘　　要：本文根据普通的三相锁相环在电压突然跌落、谐波产生时不易消除影响的缺点,提出了基于双MAF的三相锁相环模型,对所提出的模型进行建模与仿真.仿真结果表明,在三相电网电压突然跌落和出现谐波时,文中所提三相锁相环均具有较好的性能。In this paper,a three-phase phase-locked loop model based on double MAF is proposed,which is not easy to eliminate the influence when the voltage falls suddenly and the harmonic generation is produced.The model is modeled and simulated.The simulation results show that the three-phase phase locked loop has good performance,when the grid voltage falls suddenly and the harmonics appear.

关 键 词：电压跌落 MAF 锁相环
