摘要
针对环境温度影响风电机组的输出功率及发电量计算的问题,通过分析风速的分布建立威布尔分布模型;分析温度对风电机组输出功率的影响,推导出温度归一化的功率折算公式,将功率折算到统一基准温度下,提出基于温度归一化的风电机组发电量计算模型。以新疆某风电场为算例,分别计算出4台风电机组的发电量,将温度归一化模型和传统算法计算的发电量与实测SCADA数据进行对比,验证温度归一化模型计算发电量的精确性。
Aiming at the effect of ambient temperature on output power and calculation of power generation quantity of wind turbine,the Weibull distribution model was set up through analysis of wind speed distribution.The effect of temperature on output power of wind turbine was analyzed,the power conversion formula with temperature normalized was derived,in which the power was calculated in a uniform reference temperature,the calculation model of power generation quantity of wind turbine was proposed based on temperature normalization.Taking a certain wind farm in Xinjiang as an example,the power generation quantity of four wind turbine were respectively calculated,the calculated power generation quantity based on temperature normalization model and traditional algorithm were compared with the measured SCADA data,verified the accuracy of power generation quantity calculated by temperature normalization model.
