一种风电机组风功率数据清洗方法
摘要：
本发明涉及一种风电机组风功率数据清洗方法，该方法包括如下步骤：(1)根据风速大小将待清洗的风功率数据划分为若干个数据区间；(2)对于每个数据区间分别采用变点分组‑四分位法进行数据清洗，剔除异常数据；(3)将清洗后的数据区间进行组合得到清洗后的风功率数据。与现有技术相比，本发明数据清洗效果好，效率高，并具有较强的通用性。
摘要（英）：

The invention relates to a cleaning method for the wind power data of a wind generating set. The method comprises the following steps that (1) the wind power data to be cleaned are divided into a plurality of data intervals according to the wind speed; (2) each data interval is subjected to data cleaning by adopting a variable-point grouping-quartile method, and abnormal data are removed; and (3)the cleaned data intervals are combined to obtain the cleaned wind power data. Compared with the prior art, the method has the advantages of being good in data cleaning effect, high in efficiency andhigh in universality.
