Wind/solar hybrid generation control method and system with function of reactive self-compensation

The invention discloses a wind/solar hybrid generation control method and system with a function of reactive self-compensation. The method employs a method of reactive signal averaging, and employs the coordination of a plurality of photovoltaic power generation units at a wind/solar hybrid generation station for active/reactive control. A wind power generation unit outputs electric energy, and the quality of electric energy is solved at a high-voltage side of a draught fan box-type transformer. The photovoltaic power generation units achieve the active/reactive regulation of the whole power station. Reactive power compensated by a photovoltaic array is uniformly distributed to each unit photovoltaic power generation system. Each device of the whole power generation system is used reasonably, thereby achieving the reactive self-compensation of a wind/solar hybrid generation system, and achieve a purpose of maximizing benefits in a life cycle of the devices. The system makes the most of characteristics of two types of energy, reasonably uses each device of the system from the aspect of the whole power generation system, achieves the purpose of maximizing benefits in the life cycle of the devices, saves a dedicated reactive compensation device, reduces the initial investment, and improves the utilization rate of devices.
