Photovoltaic water pump system is a new type of water pump system that uses solar cells to directly convert solar energy into electricity and drives motors and pumps to lift water. Since 1978, photovoltaic water pump systems have gradually become the preferred technology for countries to solve drinking water problems in remote areas. Especially in In dry areas with no electricity or lack of electricity, solar photovoltaic water pumps are a powerful tool to solve the problems of human and livestock drinking water and small farmland irrigation. The performance of the photovoltaic water pump control system is gradually improving, and the photovoltaic water pump with the maximum power point tracking (Maximum PowerPoint Tracking, MPPT) function The development of the system controller has become a hot topic in this technology. The working mode of the sun automatic tracking system is analyzed, and the energy-saving effects of various common systems are compared, and specific conclusions are given. Through the common constant voltage tracking In-depth analysis of MPPT implementation methods such as power feedback method, disturbance observation method, and incremental conductance method are carried out. Aiming at the shortcomings of the disturbance observation method and the incremental conductance method, a fast tracking method and variable step length optimization are proposed. The algorithm integrated control strategy is to find the maximum power point of the photovoltaic cell array, so that the system can track the maximum power of the photovoltaic cell under any temperature and sunshine conditions, and the MATLAB software is used for simulation. The simulation shows that the improved algorithm improves the system performance. Stability and rapidity, tracking accuracy is significantly improved. Under the premise of ensuring that the MPPT control strategy can be realized, the hardware circuit and software design such as photovoltaic array, inverter circuit, motor and water pump system, control system, data acquisition, power supply, etc. are designed Idea and design flow chart.
