The Design Of 5kw Photovoltaic Grid-Connected Generation System And The Research On Its Control System

This article design 5kw photovoltaic grid-connected generation system. A method of islanding detection is proposed and a Simulation Study of MPPT strategy of photovoltaic grid-connected generation system based on fuzzy control is designed. A simulation study of double closed loop control with SVPWM algorithm is designed. First, the background of photovoltaic grid-connected generation system and Development Status at home and abroad are introduced. Seeking Green Energy to Instead of traditional fossil energy sources is the only solution of Energy crisis and Environmental Pollution. Under these conditions, the world's cleanest, most abundant, with great development prospects for the development of solar energy has been energetically . Second, 5kw photovoltaic grid-connected generation system is design and it is successful achieve the grid system. Research of the causes of the hot spot effect is done and the hot spot effect that may happen in the project is comprehensive analysis. Shadow testing is done at the preliminary installation place and final installation eligible place is selected. The construction program and electrical circuit is designed. Third, a simulation study of MPPT strategy of photovoltaic grid-connected generation system is designed that based on fuzzy control. Some of the existing maximum power point tracker is learned and the more important research is done on MPPT strategy of photovoltaic grid-connected generation system based on fuzzy control and a simulation model is built. The Simulation diagrams show that the maximum power tracking fuzzy controller achieved good results. A simulation study of double closed loop control with SVPWM algorithm is designed. The simulation diagrams show the double closed loop control with SVPWM algorithm achieved good results.
