摘要
针对风电机组偏航控制系统在实际应用中自适应水平差、控制精度低等问题,首先利用某风电场的实际运行数据,分析了当前该风场风电机组偏航系统的控制性能;其次根据对风误差随风速的变化特点,提出了分风速段的偏航控制策略优化方案;最后选择相关性最好的两台机组进行了实验验证。实验结果表明,优化后的偏航控制策略能够在不增加机组偏航次数的前提下有效降低机组的对风误差,提升机组的出力性能。
The wind turbine yaw control system currently used encounters the problem of low-level adaptability to the environment and low control accuracy. The paper first analyze the control performance of the current yaw control system based on the running data of the wind turbines located at the target wind farm. The wind speed dependent yaw error has been identified, then a segmented yaw control optimization scheme is proposed. Two wind turbines have the best correlation have been selected to validate the proposed method. It has been shown that, the optimized yaw control scheme can reduce the yaw error effectively while do not increase yaw times, hence to increase the power production of the wind turbine.
