Abstract
This work proposes a single phase software phase-locked loop (SPLL) which has a good performance under distorted grid voltage condition. It can estimate the phase angle correctly despite that the grid voltage contains DC component and it solves the problem that the FFT algorithm can´t generate the grid voltage phase angle correctly when the grid voltage frequency changes in a step manner.
