摘　　要：随着各类敏感型用电设备在电网中的大量投入使用,电力用户对配电系统电能质量的要求也不断提高。针对电压闪变偏移仍是电能质量优化研究的重要问题之一,提出一种基于软件锁相环为基础的正弦跟踪算法。通过运用一种新型的锁相环技术,并经仿真试验,证明该正弦跟踪算法能快速计算出电网电压的谐波和电流的幅值、相角、频率,达到跟踪正弦函数的目的。With all kinds of sensitive electrical equipment put into use in the power grid, the users＇ requirements of power quality are increase. Because the voltage flicker migration is still one of the important problems of power quality optimization research, proposes a sine tracking algorithm based on software phase-locked loop. By using a new type of phase-locked loop technology, and the simulation test proves that the sine tracking algorithm can quickly calculate the power grid voltage harmonics and current amplitude, phase, frequency, which achieves the goal of tracking sine function.
