Study on Output Characteristics of Wind Turbine based on Real-time Power Curve

基于实时功率曲线对风电机组出力特性进行分析,主要通过采集风电机组风速、功率、可靠性状态、大气压力、环境温度等历史数据进行过滤修正,计算出能够反映风电机组真实出力情况的实时功率曲线,并与出质保检测功率曲线进行对比,最后结合功率一致性系数对风电机组出力特性进行评价。找出性能下降比较严重的风电机组并及时整改,进而提高风电机组的发电能力。该方法不仅能够在线评价风电机组的性能优劣,且适用于各类型风电机组,具有广阔的应用前景。

Based on real-time power curve analysis of wind turbine output characteristics, mainly through state acquisition wind turbines wind speed, power, reliability, and the atmospheric pressure, temperature, such as historical data filtering correction, it calculates the wind generator which can reflect the real output of real-time power curve. Compared with the quality assurance testing power curve, it finally combines the consistency coefficient to evaluate wind turbine output characteristics and find out the performance degradation on serious wind turbines with timely rectification, which enhanced the capacity of wind turbines.
