Wind-driven rotating device and driving method thereof

Abstract

The invention provides a wind power drive rotating device and a drive method thereof. The wind power drive rotating device comprises a rotating component with a spindle, a rotary actuator connected with the spindle of the rotating component and capable of driving the rotating component to rotate, and a drive device used for driving the rotary actuator and including a controller, wherein the controller is used for obtaining the self-rotation stop signal of the rotating component and responds to the self-rotation stop signal of the rotating component, the rotary actuator is controlled to be switched to the work state from the stop state, and the aims that under the condition without wind, the rotary actuator drives the spindle of the rotating component in the rotating device to rotate, and the icing of the wind power drive rotating device can be prevented are achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind-driven rotating device and a driving method thereof. Background technique [0002] At present, wind power technology is developing rapidly. Many wind power stations are installed in alpine regions and inland alpine areas. However, the weather conditions in alpine regions and inland alpine areas are often harsh. Wind turbines and their components are often exposed to low temperature and humidity Therefore, wind turbines and their components are facing the problem of icing, especially in winter, the problem of icing is more serious. [0003] In wind turbines, anemometers and wind vanes are the most important sensors for wind condition detection. Wind speed etc. The wind vane is an indispensable device in the yaw system of the wind turbine. The wind vane is used as an induction element to transmit the electrical signal of the change of the wind direction to th...

Problems solved by technology

[0004] However, in a harsh meteorological environment, when liquid water enters the gap between the main shaft of the anemometer or wind vane and the matching installation part, if the wind speed in the operating environment of the anemometer or wind vane is very small (close to or reaches calm wind) and When the ambient temperature drops below zero, keep the main shaft of the anemometer or wind vane in a static state for a period of time, and the liquid water will freeze, making the main shaft and the matching installation part frozen together and unable to rotate

After the anemometer is frozen, the wind turbine will not be able to detect the wind speed value, and it will not start normally after the wind blows.

After the wind vane freezes, the wind vane will not be able to detect the change of wind direction, and then the wind turbine will not be able to accurately yaw against the wind, which will also affect the power generation

And once the anemometer or wind vane freezes, it usually takes a long time to melt the ice, which will seriously affect the power generation of the wind turbine

Although in the prior art there has been a heating method to de-ice the anemometer or wind vane, but due to the low temperature of the environment where the wind turbine is located, the heat provided by the heating device will be quickly dissipated, so the de-icing effect is relatively poor
