| Summary | Based on the data of immediately application and conversion to the reliable information, the establishment of automatic detection system for abnormal data is to be necessary. In this study, six kinds of common probability density function of wind speed are discussed. We also consider the time change according to the wind speed difference at different time intervals for statistical distributions, and in five probability density function for comparison. The analysis showed that the use of wind speed direct detection of abnormal data, due to different sampling methods have different detection criteria, therefore, the effect of the abnormal data detection will be reduced. Compared to use of the wind speed varies with the time difference between the detection of abnormal data,since the sampling methods will not affect the detection criteria, and therefore, relatively good effect of detection. |
