摘要
准确获得电网电压的相位角,在电力电子装置设计中有重要的意义。文中提出了一种在dq坐标下用DSP实现的三相软件锁相环,采用滞后控制器使其具有很强的抗干扰能力,和传统的锁相环相比,软件锁相环在实际应用中有更好的效果。
To obtain phase accurately is important in a design of power electronic equipments. Three phases Software Phase-Locked Loop(SPLL) based on DSP in the dq reference frame is proposed in this paper. Time-lag controller makes SPLL more robust. The performance of SPLL is more satisfactory compared with the tradition ones.
