Abstract

A novel real-time damping control method of a yaw system of a wind generating set comprises receiving wind direction data and wind speed data in current state by using a wind indicator if yaw movement is needed in a normal operation process of the wind generating set; and sending the wind direction data to the yaw system after obtaining the yaw system, calculating needed yaw angles by a system according to the wind direction data and conditions of the wind generating set at current, then calculating best yaw speed in the current condition through the system by using the yaw angles according to a relationship between the yaw angles and the yaw speed.

Description

technical field

[0001] The invention relates to a control method for a wind power generating set, in particular to a novel real-time damping control method for a yaw system of a wind generating set. Background technique

[0002] The yaw brake assembly is an important part of the yaw system of the wind turbine, which consists of a brake disc, a hydraulic brake caliper, a friction brake pad and a hydraulic station. During the yaw process of the generator set, the damping force provided by the brake components should remain stable, and abnormal vibration and noise are not allowed during the braking process, so as to ensure the normal service life of the brake friction lining. The pressure value provided by the hydraulic system during the yaw braking of the existing large-scale wind turbine is a set constant value, and the yaw speed is also a constant value. When the yaw system receives a yaw command, the yaw drive starts with a constant power The action drives the large gear o...
