Research on Data Quality Evaluation Model for Wide-area Distributed Power Quality Monitoring System

Affected by the reliability and the communication mode of the power quality monitoring terminal and the increasing scale of the power gird, the data quality problems of the wide-area distributed power quality monitoring system have been gradually exposed. Based on the architecture of the wide-area distributed power quality monitoring system, this paper analyses the influence factors of the data quality and puts forward a data quality evaluation model. The application of the data quality evaluation can improve the reliability of analysis and decision results based on the power quality data.
