| 摘 要： | 风电机组历史功率数据是进行风电研究的重要基础,而风电机组实际采集到的数据中存在大量的异常数据,这给风电功率预测研究带来许多不利影响。对历史数据的风速-功率对应关系进行研究,识别并剔除异常数据。分析风速升降变化对功率的影响,建立SVM数据重构模型。根据风速升降特性及强相关风电机组的出力特性对数据重构模型加以改进。以风电机组的实测数据为例进行仿真计算,结果表明所述方法能够对异常数据进行有效地识别和重构。

| Abstract: | The historical power data of wind turbine is the important foundation for the study of wind power. However, amounts of data collected from wind farms usually contain abnormal data, which has adverse effects on the wind power prediction. First, the wind speed-power correspondence of historical data is studied, and the abnormal data is identified and eliminated. The influence of RISE-FALL-feature of the wind speed on the power is analyzed, and the SVM data reconstruction model is established. A data reconstruction model is improved based on the RISE-FALL-feature of the wind speed and the output characteristics of the correlation wind turbine. Taking the measured data of wind turbine as an example, the simulation results show that the method described in this paper can effectively identify and reconstruct the abnormal data. This work is supported by National Key Research and Development project of China (No. 2018YFB0904200). |
