摘要
风速-功率是风电机组发电性能的重要指标，对风电场的运行管理具有重要意义。风速-功率数据是通过安装在风电场的监视控制与数据采集（SCADA）系统采集得到的，原始数据存在大量噪声，给后续应用研究带来了很大的挑战。基于风速-功率数据的空间分布特征，将风速-功率数据分为3类，并改进了数据预处理方法bin算法，提出了基于分区域（dbin）算法的异常数据识别清洗方法及流程。实验结果表明，dbin算法识别异常数据的效率比传统算法更高，具有较强的通用性。
Abstract
Wind power is an important indicator of the generating performance of wind turbines
which is of great significance to the operation and management of wind farms.The wind-speed and power data were collected through the monitoring and control (SCADA) system installed in the wind farm.There are a lot of noises in the original data
which brings great challenges to the subsequent application research.Based on the spatial distribution characteristics of wind-speed and power data
wind-speed and power data was divided into three categories
the data preprocessing method bin algorithm was improved
and the method and process of abnormal data identification and cleaning based on district bin(dbin) algorithm were proposed.The experimental results show that the dbin algorithm proposed in this paper is more efficient than the traditional algorithm in identifying abnormal data
and has strong universality.
