Abstract: With the increasing reduction of fossil energy and the serious environmental pollution, the core technology of high-power solar power has become one of the new focuses of energy research. This article mainly aims at introducing the MW-class photovoltaic power generation system and putting forward a feasible design plan. The scheme adopted the monitoring device of RS485 communication mode, monitoring the working environment, operational status and operating parameters in real time, to effectively avoid islanding effect, abnormal voltage and frequency, and other potential risks. In order to verify the feasibility of high-power photovoltaic grid-connected power system, analogue simulation was done using MATLAB/SIMULINK; the simulation and experimental results showed that the MW-class photovoltaic power generation system is not only enlighten and validate the construction of MW-class photovoltaic power station, but also promote the development of photovoltaic power generation system. This paper has studied in detail using MATLAB simulation based on the existing data; the simulation results are of guiding significance for engineering practice.
