Problems solved by technology

At present, the regular lubrication of yaw bearings mainly adopts the method of stopping first and then lubricating. It takes tens of minutes to perform each lubrication operation, and the interval between two adjacent lubrication operations takes about one week. However, this regular lubrication method It will lead to frequent shutdown of wind turbines, which will not only reduce the power generation of wind turbines, but also be detrimental to the stable operation of wind turbines

Abstract

The invention discloses a yawing greasing method and device and a computer readable storage medium. The yawing greasing method comprises the steps that if it is detected that a yawing bearing of a wind generating set has the greasing demand, greasing operation is conducted on the yawing bearing in the first-time yawing process of the wind generating set; and if a difference value between a maximumangle value and a minimum angle value of the greased zone of the yawing bearing is smaller than a preset greasing angle after first-time yawing is finished, greasing operation is conducted on the yawing bearing according to the actual cabin position in the next-time yawing process, the greased zone obtained after first-time yawing is finished and the preset greasing angle. By adopting the technical scheme in the embodiment, the yawing bearing can be lubricated in the set yawing process, and frequent halting of the wind generating set is avoided.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to a yaw greasing method and device, and a computer-readable storage medium. Background technique [0002] In order to ensure that the yaw bearing of the wind turbine can operate in a well-lubricated state, the yaw bearing needs to be lubricated regularly. The lubrication of the yaw bearing mainly includes rolling element and raceway lubrication and outer ring tooth surface lubrication. Among them, the lubrication of the tooth surface of the outer ring requires the yaw system to work at the same time to evenly lubricate the tooth surface. At present, the regular lubrication of yaw bearings mainly adopts the method of stopping first and then lubricating. It takes tens of minutes to perform each lubrication operation, and the interval between two adjacent lubrication operations takes about one week. However, this regular lubrication method It will lead to frequ...
