Abstract

In order to increase the power generation of wind turbine generator system (WTGS) and extend the service lifespan of the yaw system, this article proposes a control strategy of power increase and lifespan extension for the yaw system based on power loss of wind turbine. Firstly, the traditional yaw system control strategy is introduced, and the relationship between wind speed, yaw angle, and wind power loss is analyzed; Secondly, based on the principle of power increase and lifespan extension control in yaw systems, the power loss of wind turbine and its delay time are taken as control parameters, then a yaw system control model based on power loss control is obtained; Thirdly, in order to simultaneously considering maximum wind turbine power generation and minimize the count of yaw system actions, a dual threshold objective function for the yaw system is constructed, then the power loss threshold and delay time threshold are obtained by using historical monitoring data of wind turbine and genetic algorithm; Finally, the example verification shows that compared with traditional yaw system control strategy and the control strategy based on wind speed interval division, the control strategy proposed in this article can achieve the transfer and allocation of yaw system action count in high, medium, and low wind speed ranges, which can reduce the total count of yaw system actions, and have important application value in improving wind turbine power generation and extending the service lifespan of yaw system.
