In order to completely solve the problem of power quality, we must first have a comprehensive and systematic understanding and mastery of the power quality of the power grid, analyze its occurrence law, and find out the specific reasons for the decline of power quality, so as to take targeted measures for comprehensive treatment to prevent or avoid the relevant losses caused by the decline of power quality.

        Build a power quality monitoring system to monitor, analyze and process power quality parameters such as harmonics, voltage fluctuation and flicker, voltage imbalance, frequency and voltage deviation in real time.

        The power quality monitoring system realizes the comprehensive monitoring and unified management of power quality indicators. The system establishes a power quality data center by collecting the power quality data of each monitoring point of the power grid, which is the basis of power quality analysis, evaluation and comprehensive treatment. Through point to area multi-level comprehensive evaluation and analysis of power quality, it provides scientific basis and decision support for comprehensive management of power quality, power production, technical supervision and management, user supervision, power grid design and other fields.
