The invention discloses a wind power generation system for speed regulating by using solar energy. The wind power generation system comprises a supporting structure, a generator, a wind power impeller, a condensation system, a solar thermal collector, an air duct and an automatic control system. According to the wind power generation system, heat power is provided for air flow in a solar heating mode, airglow is led to an airflow nozzle in the far shaft end of a blade of the wind power impeller, meanwhile, the automatic control system and a three-way valve are used for controlling the spraying direction and the spraying dose of the airflow in real time, the wind power impeller is accelerated or decelerated, so that the rotating speed of the wind power impeller is stabilized to a certain degree, frequency and power output of the wind driven generator is also stabilized, the problems that an existing wind driven generator is large in power output fluctuation and unstable in frequency are solved to some extent, and therefore the wind power generation system has the advantages of being novel in structure and complete in resource utilization.
Description
technical field [0001] The present invention relates to wind power generation systems. Background technique [0002] In recent years, as a clean and renewable energy technology, wind power has been greatly developed, but it has also encountered some problems. The most prominent thing is that wind power generation is greatly affected by changes in natural conditions, and it is difficult to stabilize and adjust the speed of wind turbines, resulting in large fluctuations in power output and unstable frequencies. These disadvantages have seriously affected the ability of wind power plants to connect to the main power grid, resulting in severe wind curtailment. [0003] In my country, areas with relatively abundant wind energy generally have longer average annual sunshine hours and have a good solar energy foundation. After the solar energy is gathered, a high-temperature heat source can be obtained, which can be used as an energy source for wind turbine speed regulation. Con...
