Abstract
According to the principle of phase lock loop, a software phase lock loop (SPLL) for photovoltaic (PV) grid-connected power system has been designed, which used to decrease the phase differ between PV output current signal and utility voltage signal, so to make power factor close to 1. For this kind of software phase lock loop, the implementation scheme is given in detail, and combine with the program flowchart, the realization of the scheme is explained. Under the condition of the laboratory, experiment is carried out. The results show that the proposed scheme has certain feasibility and availability.
