Abstract: Grid-connected PV system is one of the technologies to use the solar energy. Grid-connected inverter is a core part of linking the grid. In order to make the output current of grid-connected inverter track the grid voltage fundamental and complete the Genlock, this paper uses 1kW single-phase photovoltaic grid-connected inverter as research platform. The paper describes the working principle of the photovoltaic grid-connected inverter and the system architecture. It analyzes the control technology of grid-connected inverter and proposes a software phase-locked loop of a dual-park phase detector based on coordinate transformation. At last it verifies the feasibility of this method by Matlab simulation.
Key words: single-phase photovoltaic grid-connected inverter, network control, software phase-locked loop, Matlab simulation
