Research on Three Phase Photovoltaic Grid-connected Inverter

This paper presents the structure of three phase photovoltaic grid-connected system.A simulation model for photovoltaic array simulator under Matlab environment based on the mathematical modules of PV arrays is built up.The simulation model of photovoltaic array simulator is used in three phase photovoltaic grid-connected system.The system includes the function of maximum power point tracking(MPPT).It can make photovoltaic grid-connected inverter woke in the best point.The feasibility and rightness of the method are verified through this simulative analysis.
