中文摘要: 针对普通的三相锁相环在三相电压不对称时不易消除二次谐波的缺点，提出了基于双d-q旋转轴的三相锁相环模型，对所提出的模型进行建模与仿真.仿真结果表明，在三相电网电压平衡和不平衡两种情况下，双d-q旋转轴三相锁相环都能准确锁相.

中文关键词: 双d-q旋转轴三相电压不对称锁相环

Abstract:The model of three-phase phase-locked loop based on double d-q rotating shaft is proposed in view of the shortcomings that common three-phase phase-locked ring is not easy to eliminate the second harmonic under asymmetrical three-phase voltages,and the modeling and simulation of the proposed model is carried out.The simulation results show that double d-q rotating shaft three-phase phase-locked loop can lock phase accurately in the conditions of balanced and unbalanced voltage of the three-phase power grid.

keywords: double d-q rotating shaft three-phase voltage asymmetry phase-locked loop
