The wind power generation part uses the wind turbine to convert wind energy into mechanical energy, and then converts the mechanical energy into electrical energy through the wind turbine, then charges the battery through the controller, and supplies power to the load through the inverter;
The photovoltaic power generation part uses the photovoltaic effect of solar panels to convert light energy into electrical energy, then charges the battery, and then converts direct current into alternating current through the inverter to supply power to the load;
The inverter system is composed of multiple inverters, which convert the DC power in the battery into a standard 220V AC power to ensure the normal use of AC load equipment. At the same time, it also has the function of automatic voltage stabilization, which can improve the power supply quality of the wind-solar hybrid power supply system;
The control part continuously switches and adjusts the working state of the battery pack according to the changes in sunlight intensity, wind force and load: on the one hand, the adjusted electric energy is directly sent to the DC or AC load. On the other hand, excess electrical energy is sent to the battery pack for storage. When the power generation cannot meet the load demand, the controller will send the electric energy of the battery to the load to ensure the continuity and stability of the entire system;
The battery part is composed of multiple batteries, which play two roles of energy regulation and load balancing in the system at the same time. It converts the electrical energy output by the wind power generation system and the photovoltaic power generation system into chemical energy, and stores it for use when the power supply is insufficient.
According to the change of wind and solar radiation, the wind and solar hybrid power supply system can operate in the following three modes: the wind turbine alone supplies power to the load; the photovoltaic power generation system supplies power to the load alone; the wind turbine and photovoltaic power generation system jointly supply power to the load.
