The invention provides wind-solar complementary equipment and a control method, the wind-solar complementary equipment comprises a wind power generation device, a photovoltaic thin film assembly, a photovoltaic power generation controller and a photovoltaic tracking device, the photovoltaic power generation controller and the photovoltaic tracking device are arranged on a tower drum of the wind power generation device, and the output end of the photovoltaic thin film assembly is connected with the wind power generation device. The photovoltaic power generation controller is connected with the photovoltaic tracking device, and the photovoltaic tracking device is provided with a photovoltaic thin film assembly, thereby achieving the integration of photovoltaic power generation and wind power generation. The photovoltaic power generation controller calculates the maximum photovoltaic power generation power according to the wind power output power of the wind power generation device and the real-time output power of the photovoltaic thin film assembly, and adjusts the tracking angle of the photovoltaic tracking device based on the magnitude relation between the maximum photovoltaic power generation power and the real-time output power. According to the invention, the tracking angle of the photovoltaic thin film assembly is adjusted through the photovoltaic power generation controller, so that light energy can be received to the greatest extent, the light energy utilization rate is improved, and the power generation power of the wind-solar complementary equipment is further improved.

Description

technical field [0001] The invention relates to the field of power generation, and more particularly, to a wind-solar complementary device and a control method. Background technique [0002] Wind power generation and photovoltaic power generation develop rapidly, the photovoltaic power generation system does not work at night, and the wind power generation system generates a large amount of electricity at night. The photovoltaic power generation system generates electricity normally during the day, while the wind power generation system generates less power during the day. Therefore, in order to take advantage of the complementarity of the two energy sources, wind-solar hybrid power stations came into being. [0003] At present, when the wind-solar hybrid power station is configured, the photovoltaic modules in the photovoltaic power generation system are directly fixed on the ground, and the light energy utilization rate of the photovoltaic modules is low, which in turn ma...
