It is statistical that renewable energy is consumed about 14 hundred million (wt.) oil equivalent in 2002, and will exceed 22 hundred million (wt.) oil equivalent in 2030. The wind power generation is a renewable energy power generation with the most mature technology except for hydroelectric power generation, and the installed capacity of the wind power generation accounts for the vast majority of the total installed capacity of the whole renewable energy power generation. However, due to the limitation of the performance of the power electronic device, a certain bottleneck is caused to the development and application of a large-capacity wind turbine generator. With the further development of power electronic devices and energy storage devices of large power strings, wind power generation can compete with conventional energy in terms of total investment or power generation cost, and the wind power generation technology can be developed more greatly. The wind generating set comprises a wind wheel and a generator; the wind wheel comprises blades, a hub, a reinforcing member and the like; it has the functions of wind driven blade rotation to generate electricity, generator head rotation, etc. The wind power generation power supply comprises a wind generating set, a tower frame for supporting the generating set, a storage battery charging controller, an inverter, an unloader, a grid-connected controller, a storage battery pack and the like.
