Research on Evaluation Index System and Evaluation Method of Distribution Network Fault Outage Risk Under the Background of Big Data

The current distribution network fault failure evaluation method has the problem of too fuzzy reactive compensation capacity, which leads to a high line loss rate. It designs a distribution grid failure evaluation method based on big data of the evaluation system and evaluation method. Get the line loss index, refine the structure planning of the network frame, adopt the combination of high voltage compensation and low voltage compensation, clarify the reactive power compensation capacity, evaluation system and evaluation method Big data to calculate the line loss rate of the distribution network, measure the power difference of the power meter, adjust the failure evaluation mode, and shorten the distance between power supply and load. Experimental results: The mean fault power failure evaluation method and the other two failure power failure assessment methods are 2.398%, 3.461% and 3.516% respectively, indicating that the distribution network optimization method integrating the evaluation system and evaluation method big data, which is more suitable for application to the distribution network operation planning.
