               There are some problems in power grid, such as harmonic, reactive power, voltage flicker and negative sequence current, which seriously affect power quality and endanger power equipment. It is necessary to build an on-line power quality monitoring system. Power quality monitoring system is a kind of equipment for on-line power quality monitoring, which needs to be used in many scenarios.

                The hardware system of the power quality online monitoring system is used to collect the data information of the power quality monitoring device, wherein the data information includes normal data and abnormal data. The data acquisition and storage system of the power quality online monitoring system is used to transmit the collected data to the central database for storage. The central database is used to collect the data information of the power quality monitoring device collected by the hardware system of the power quality monitoring system.

                The monitored data is collected through the data acquisition and storage system of the power quality online monitoring system, and the obtained data information is transmitted to the central database. The operating system of the power quality monitoring system analyzes the data by retrieving the data in the central database.

                The power quality online monitoring system provides real-time monitoring, data statistics and storage functions, timely finds the power quality events or index out of limit events at each monitoring point, gives alarm prompt, automatically calculates the index qualification rate, and saves the event information and index statistical results to the database as the basis for power quality analysis.
