In this paper, the research and design of solar photovoltaic power generation control system . First introduced solar power technology at home and abroad , and the development of the status quo . Followed by analysis of the working principle of the photovoltaic cells and compare several maximum power point tracking algorithm , Boost type DC / DC converter suitable method to achieve the maximum power tracker design , the experimental data show that the controller can not only adapt to the light intensity characteristics of rapid change , and can quickly and accurately track the maximum power point . Then -depth study of the three-phase voltage -type active inverter , a detailed analysis of the basic principle of SVPWM control technology and its control algorithm , inverter and photovoltaic power generation control system design , experimental results prove that the system the control method is feasible .
