Abstract

The invention discloses a yaw control device, an executive device and a yaw system and method. The yaw control device comprises a measuring unit, a yaw controller, an electric power conversion unit and an electric executive unit, wherein the measuring unit is used for measuring current wind power parameters and current yaw parameters of a wind generating set; the yaw controller is used for obtaining a current damping control electric power value for execution of damping action, and sending a damping control instruction used for performing damping control according to the current damping control electric power value to the electric power conversion unit and the electric executive unit; the electric power conversion unit is used for responding to the damping control instruction and converting a current electric power value into the current damping control electric power value; and the electric executive unit is used for responding to the damping control instruction and sending the damping action instruction used for executing the damping action on the wind generating set according to the current damping control electric power value. According to the yaw control device, the executivedevice and the yaw system and method provided by the embodiment of the invention, the damping torque at different time points can be flexibly and precisely controlled, the wind generating set can frequently track the wind direction, accordingly, the wind energy can be better captured, and the service life of equipment is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and in particular to a yaw control device for a wind power generating set, a yaw mechanical execution device, a yaw system for a wind power generating set, a method for controlling a yaw of a wind power generating set, a yaw mechanical execution method, and a wind power generating set Damping application method. Background technique [0002] With the improvement of human environmental awareness and demand for clean energy, wind energy has been widely valued as a renewable energy. In recent years, the development and utilization of wind energy in various countries has been continuously strengthened, and wind power technology has developed vigorously. The yaw system is an important part of large wind turbines. [0003] The yaw system has three main functions: one is to cooperate with the control system of the wind turbine to drive the nacelle to rotate around the center line...
