Abstract


With the development of world economic and shortage of energy, Research on solar photovoltaic power generation system is of great theoretical and practical significance in alleviating energy and environmental problems, improving the energy consumption structure and the performance of distributed generation systems. Under this background, this paper focus on the three-phase grid-connected photovoltaic power generation system, in the terms of hardware system design, control algorithm and system simulation. In this paper, module of three-phase grid-connected photovoltaic power generation system is established. A variable step-size maximum power point tracking control strategy is proposed. And a control algorithm named double d-q axis phase-locked loop is proposed. Simulation is verified in the form of hardware.
