Abstract
Yaw system is an important part of wind turbine control system, yaw error is an important performance index of wind turbine, which has great influence on power generation. The wind utilization and the output of the power generation have been determined by the yaw error. In order to make the wind turbine better aligned toward the wind direction, reduce the yaw error, and increase the power generated by the unit, the angle errors of yaw control of wind turbine have been analyzed, in this paper, and the method of wind test, the strategy of yaw control have been studied respectively. Based on the results of the study, the method of wind test, the restart control strategy of yaw system and the performance of control strategy of yaw system have been optimized in this paper. In this way, the three important links are optimized, it will effectively reduce the yaw error as well as significantly improve the wind turbine generating electricity.
Highlights
Energy crisis and environmental pollution are two of the most important issues which human faces, and are highly concerned by relevant research institutions and governments around the world
According to the field test the power generation data, the use of the wind program can make the wind power generation capacity increased by about 2.04%
The following is a summary of the assessment of generation growth after optimization: optimized, the common yaw error problems of the current wind turbine have been optimized, which has certain practical significance and effect to improve the power generation
Summary
Energy crisis and environmental pollution are two of the most important issues which human faces, and are highly concerned by relevant research institutions and governments around the world. The algorithm can determine the optimal yaw angle of wind turbine by finding the maximum power generation, and has good yaw control accuracy.
