Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a double-fed wind power generation system with energy storage. Background technique [0002] As a clean, abundant and renewable energy, wind power has been paid more and more attention all over the world, especially in recent years, it has developed rapidly. When the wind flows through the blades of the wind turbine and drives the wind turbine to rotate, the wind energy is converted into mechanical energy, and the wind turbine drives the rotor of the generator to rotate, and the generator supplies power to the grid, and the mechanical energy is converted into electrical energy. Compared with the traditional constant speed and constant frequency wind power generation system, the variable speed and constant frequency wind power generation system using doubly-fed wound asynchronous generators has significant advantages: the wind energy utilization coefficient is high, not onl...
