Wind power generating set control method, device, controller and system

Abstract

The application provides a control method, device, controller and system for a wind power generating set. The method includes: obtaining in real time the current wind direction of each upstream wind generating set in the wind farm, and determining the current main wind direction to which the current wind direction of each upstream wind generating set belongs. According to the association relationship between the main wind directions of the plurality of upstream wind power generating sets and the downstream wind power generating sets in the main wind direction, the downstream wind power generating sets associated with the current main wind direction of each upstream wind power generating set are determined. A control instruction for each downstream wind power generating set associated with the current main wind direction is determined according to the working condition state and working condition parameters of the downstream wind power generating set associated with the current main wind direction. Each downstream wind power generating set associated with the current main wind direction is controlled according to the control instruction. According to the perception information of a wind turbine to the change of the incoming wind, the adjacent wind turbines can make yaw response to the change of the incoming wind in advance, and the corresponding speed of other wind turbines to the wind yaw can be increased.

Description

technical field [0001] The present application relates to the technical field of wind power generation, and in particular, the present application relates to a control method, device, controller and system for a wind power generating set. Background technique [0002] With the gradual expansion of the scale of wind turbines and the improvement of the safety protection of wind turbines, more and more attention has been paid to the power generation and efficiency of wind turbines. [0003] In the prior art, when the wind turbines in the whole wind field are in the shutdown state, if the wind speed starts to increase, each wind turbine will independently judge the wind speed acting on itself. If the wind speed continues to be high for a continuous period of time After setting the threshold, it will start the action of yaw against the wind and enter the standby state. [0004] When the wind turbines in the whole field are in the normal power generation state, if the wind direct...
