摘要：

Based on the investigation of Guohua Yongfa wind farm, this paper optimized the control strategy of the refined control model algorithm based on the optimal blade tip speed ratio tracking for the problems existing in 1.5MW wind turbine, including: speed and torque optimization, blade pitch angle dynamic control strategy, yaw optimization strategy, rotor pitch bearing wear and high wind operation protection, etc. Optimizing the cut-in wind speed and related parameters, and optimizing the start-stop control mode and adjust the initial angle of blade installation, at the same time, studied the wind turbines supervisory control and data acquisition(SCADA) transformation technology, solved the problem of frequency converter product upgrade and replacement and put forward the improvement strategy of improving unit safety and reliability. Through the implementation of corresponding countermeasures, the generation capacity and availability of wind power units have been significantly increased, reaching the expected effect, accumulating valuable on-site application engineering experience, and laying a solid foundation for the promotion and application of the project. © 2019 Chin.
