摘要
通过分析湍流强度对风电机组输出功率统计曲线的影响,提出风电机组输出功率统计曲线的湍流强度修正方法。与按IEC标准对测试机组数据统计方法所得的结果相比,采用该文所提出的修正方法比标准统计方法所得结果的不确定度更低,可更准确反映机组实际运行状态,为机组的正常维护、运行优化及风电场建设前期发电量估算提供可靠的依据。
Through analyzing the influence of turbulence intensity on statistical power curve of wind turbine, the correction method for output power curve of wind turbine was put forward according to turbulence intensity. By comparing with the measured statistic results of the same wind turbine according to IEC standard, the measurement results by using correction method has lower uncertainty than standard statistical method, which can accurately reflect actual operation situation of wind turbine, and provide reliable basis on normal maintenance, operation optimization of wind turbine, as well as preliminary power estimation of wind farm construction.
