摘要:

叶片结冰是影响冬季我国部分高海拔高湿度地区风电机组安全运行的因素之一。及早检测出叶片结冰能够及时调整机组运行方式,保证机组安全。分析了叶片结冰对风电机组运行性能和运行参数的影响,将功率、叶轮转速和环境温度作为监测叶片结冰的变量。采用自适应增强(AdaBoost)算法分别建立功率模型和叶轮转速,引入指数加权移动平均(EWMA)方法分析功率和叶轮转速模型的预测残差,从而对叶片结冰时2个参数的异常变化进行监测,当风电机组输出功率和叶轮转速2个参数同时出现异常且环境温度低于0 ℃时发出叶片结冰预警。利用昆明某风场风电机组实际叶片结冰数据验证了该方法的有效性。

Abstract:

Blade ice accretion is a factor that affects the safe operation of wind turbines in high-altitude and high-humidity areas of China in winter. Early detection of ice accretion and making adjustment on operation mode timely can guarantee the safety of wind turbines. The effects of ice accretion on the operation performance and parameters were analyzed thoroughly, and power, rotor blade speed and ambient temperature were taken as variables to monitor blade icing. Models of power and rotor blade speed were constructed by AdaBoost algorithm, and the prediction residuals of the two models were made by exponentially weighted moving average (EWMA), in order to detect the abnormalities of power and rotor speed. If both abnormal power and rotor speed are detected and ambient temperature drops below 0 ℃ simultaneously, the blade icing alarm will be triggered. The effectiveness of the method has been proved by the icing data of a wind farm in Kunming.
