Multipoint electric energy quality monitoring system for transformer station

The invention discloses a multipoint electric energy quality monitoring system for a transformer substation. Based on a plurality of electric energy quality parameter acquisition nodes and transformerstation working condition acquisition nodes, electric energy quality parameters and transformer station working condition parameters are autonomously acquired. the electric energy quality parametersand the transformer substation working condition parameters are uploaded, processed and identified through the monitoring terminal to obtain an electric energy quality event identification result anda transformer substation working condition evaluation result; and a corresponding maintenance strategy is obtained and output according to the power quality event identification result and the transformer substation working condition evaluation result. The curve graph is generated according to the preset drawing rule, and the display screen is controlled to display the curve graph, so that visualexpression and accurate classification and identification of the power quality events are realized, evaluation of the working condition of the transformer substation is realized, a maintenance strategy can be automatically provided, and stable operation of the transformer substation and power quality of the transformer substation are guaranteed.
