Problems solved by technology
At present, the conventional wind power generation system has to go through two energy conversions in the process of energy transmission and distribution: electrical energy-chemical energy-electrical energy, and the utilization rate of energy is low.
And it is also prone to the situation that the energy generated by wind power generation is small and cannot meet the electric energy demanded by the load

The present invention provides an adaptive wind power generation system. The adaptive wind power generation system comprises a wind wheel, a generator, a rectification unit, a storage battery, an inversion unit and a load. The system further comprises a control unit, a first micro-control switch, a second micro-control switch, a third micro-control switch, a fourth micro-control switch, a fifth micro-control switch, a DC / DC conversion unit, a battery control unit, an energy releasing load and a mechanical brake device. According to change of a wind speed, change of a load and change of a storage battery energy storage capacity, the adaptive wind power generation system performs adaptive switching control of an energy transmission distribution process of the wind power generation system totake electric energy supplied by a wind generator as the principal thing and take discharge of the storage battery as the secondary thing, and therefore, stable operation of the wind power generationsystem is ensured, the safety working of each device in the wind power generation system is protected, wind and power conversion efficiency is improved, maximized utilization wind energy is achieved,very beneficial information is provided for research of electric energy change of the direct drive wind power generation system, and the adaptive wind power generation system has very important socialbenefit and economic benefit.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to an adaptive wind power generation system. Background technique [0002] With the development of the economy and the growth of the population, human beings' demand for energy increases, but the conventional energy sources such as coal and oil are limited, and pollute and destroy the natural environment. Wind energy is a clean and renewable energy source, which is rich in resources and does not need to be mined or transported. At present, the wind power generation system is divided into non-direct drive wind power generation system and direct drive wind power generation system. The former mainly uses the gearbox to increase the speed of the wind turbine to drive the conventional asynchronous generator; The gear box reduces the volume and weight of the wind turbine, saves maintenance, and reduces the operating noise of the wind turbine. [0003] The direct-drive wind...
