Abstract:
In view of the adverse effects of data quality problems caused by outliers on power applications,the characteristics of power sensor data are analyzed. Based on the temporal characteristics of power sensor data and the usability of anomaly detection technology,an electric power sensor data oriented outlier detection solution isproposed,which consistsofan anomaly detection service framework and an outlier detection method. The anomaly detection service framework refers to the idea of Web service,and based on big data technology it can support the storage and calculation? of power sensing data,and provide anomaly detection capability of power sensing data in the form of service. The outlier detection method is accomplished on the basis of clustering algorithm and a temporal characteristics related data segmentation method to detect outlier anomalies in power perception data. The feasibility and effectiveness of the proposed method are verified by experiment. The results show that this method can effectively identify outliers in power sensing data which are time-related and time-continuous,and has great parallelism and scalability when the data scale increases.
