Background
The traditional small and medium-sized wind power generation system mainly comprises a tower, a cabin, a wind wheel, a generator, an energy storage system and a control system. The wind wheel drives the generator to rotate through the coupler, converts wind energy into electric energy to be stored in the energy storage system or is connected with each stage of power station through a power grid. The generators in the conventional wind power generation system are mainly of two types:
for wind power generation systems with the power of less than 50KW, the generator used by the wind power generation system is a squirrel-cage three-phase asynchronous motor. The generator has larger volume, low power density and heavy weight, so a larger platform needs to be built at the top end of the tower frame to install the squirrel-cage three-phase asynchronous generator; and the strength requirement on the tower is high, a large amount of concrete needs to be poured for foundation construction to enhance the wind resistance of the tower, the manufacturing cost is high, the construction period is long, and the operation cost is high.
For a 100KW-300KW wind power generation system, a generator used by the system is a generator set, the volume is larger, and the weight of the whole generator set is usually as high as about 1.5 tons to 5 tons. Such heavy weight generator sets are difficult to install on the platform at the top of the tower, and the early construction costs are enormous. Therefore, the wind wheel, the engine room, the energy storage system and the control system are only installed at the top end of the tower, the generator set is installed on the ground, and power is transmitted between the generator set and the wind wheel at the top end of the tower through the transmission shaft, so that the generator set rotates to generate electricity. Disadvantages of such wind power systems: the transmission shaft is as high as the tower, heavy, inconvenient to install and maintain, and needs to consume wind energy to reduce the efficiency of the wind power generation system.
In addition, because the squirrel-cage asynchronous generator forming the traditional wind power generation system has larger magnetic resistance, when the wind power is smaller, the wind wheel can not drive the generator to rotate and can not generate power, and the power generation efficiency is low.

Furthermore, a cover is additionally arranged at the end part of the planetary gear.
Further, alternating current output by the coreless disk type permanent magnet generator is transmitted to the energy storage system through rectification and filtering, or is connected with a power grid through a power line and is transmitted to each level of power distribution stations.
Further, the energy storage system is mounted within the nacelle.
