Review of Power Quality Standard System

With the continuous increase of sensitive loads in the power grid, users have increasingly higher requirements for power quality. The research and practice of power quality are increasingly valued by scholars and the industry. Correspondingly, the relevant standards for power quality are also showing an increasingly rich trend. Personnel engaged in the power quality industry often have difficulty in having a comprehensive and systematic understanding of power quality standards. To solve this problem, we proposed an overview of the existing power quality standards. We firstly classify them according to organizations, such as IEEE, IEC and SAC. On this basis, various standards issued by each standardization organization are classified and discussed according to the content involved. Finally we briefly describe the content and the involved areas of the standard. This review is hoped to be helpful for related research and application.
