Problems solved by technology

[0002] At present, the early warning scheme for the voltage and reactive power operation of the distribution network is generally evaluated by evaluating the AVC operation mode of the regional voltage and reactive power control, and for the operation records of the AVC system, the distribution network operation data collected by the data acquisition and monitoring control SCADA system Carry out reactive voltage safety analysis, area analysis and AVC command analysis, and timely conduct calibration and early warning analysis. Through early warning analysis of important index data such as relevant voltage, current, power factor and input records, multi-dimensional data analysis and judgment are carried out through AVC On the one hand, due to the constraints of technical means and other constraints, there are still information bottlenecks, the early warning method is single, and the early warning methods are relatively backward.
