| 摘 要： | 在电网电压频率波动或者三相不平衡的情况下,硬件锁相很难准确检测到基波正序的相位。在结合PWM整流器空间矢量解耦控制算法的基础上,将软件锁相环技术应用在PWM整流器控制系统中,并用仿真和实验验证了该方案的可行性。实验结果表明,该方案解决了电网电压频率波动及三相不平衡时的相位同步等问题,并在工程上具有一定参考价值。

| Abstract: | It is difficult to accurate detect the phase of positive sequence fundamental component of voltage while the power network frequency is varied and three-phase is unbalanced.Based on SVPWM rectifier decoupled control,a novel soft phase locked loop is used in PWM rectifier control system,the simulative and experimental results proves the scheme is feasible.The experimental result indicated that this scheme is the solution for power network frequency variations and three-phase unbalance and so on. It has certain reference value in the project. |
