The safety protection of the wind turbine is not good, and when it comes to strong winds, the impeller will rotate faster and faster, ultimately leading to the burning of the generator. Once the generator is burned, the impeller will stop rotating. Our company has independently developed and launched a variable pitch wind turbine system, which has been in safe operation in the market for many years and has operated well without any burning accidents. At the rated speed of the wind turbine, once the rated speed is exceeded during operation, the pitch will passively force the wind turbine blades to pitch (in the forward pitch mode), adjust the speed, and achieve stable output power of the generator. At present, our company has launched a series of horizontal axis variable pitch wind turbines, including 3kw, 5kw, 10kw, 15kw, 20kw, 30kw, 50kw, 60kw, 100kw, 200kw, 300kw, and other products. Two of the 5kw models are upwind with tail rudder. Other specifications are: downwind without tail rudder.
4.3 System advantages:
1. Adopting direct drive permanent magnet generator, high-efficiency rare earth material, and shell made of carbon steel.
2. The wind turbine has a simple structure, and the hub adopts a mature variable pitch structure without complex moving mechanical components, resulting in an extremely low failure rate.
3. Adopting six high-end transmission slip rings for conductivity, without cable twisting phenomenon.
4. The vertical shaft of the rotating body has no rigid driving mechanism, and only conventional bearings are used. This structure can easily eliminate the shaking and vibration caused by unstable airflow, which is beneficial for improving the lifespan of wind turbines.
5. The generator efficiency is above 90%, and the wind energy utilization coefficient is 42%.
6. The unique and simple control method, automatically facing the wind, effectively improves the working efficiency of the wind turbine; Fully utilize the torque of the permanent magnet generator to control the blade pitch, achieving the optimal power generation state, and increasing the annual power generation by more than 30%.
7. Equipped with automatic electromagnetic unloading function.
8. Adopting a unique sealing structure, achieving thorough moisture and dust prevention.
