Abstract

The invention provides a 10kV medium-voltage line automation segmentation rationality evaluation method. TheA 10kV medium-voltage line automation segment rationality evaluation method comprises the following steps: S1, for a 10kV medium-voltage line, obtaining the number of segments of the 10kV medium-voltage line, and the number of medium-voltage users, the number of low-voltage users and the load in each segment of the 10kV medium-voltage line; S; s2, respectively utilizing the number of medium-voltage users, the number of low-voltage users and the load in each segment, and calculating unbalance coefficients of the medium-voltage users, the low-voltage users and the loads; S; s3, respectively endowing the medium-voltage user, the low-voltage user and the load with weight coefficients; and S4, calculating the imbalance coefficient of the 10kV medium-voltage line as an automatic segmented reasonability evaluation parameter by using the imbalance coefficient in the step S2 and the weight coefficient in the step S3. According to the method, three factors of a medium-voltage user, a low-voltage user and a load are integrated, and quantitative comprehensive evaluation can be carried out on the automation segmentation reasonableness of the 10kV medium-voltage line.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, and more specifically, relates to a rationality evaluation method for automatic segmentation of 10kV medium-voltage lines. Background technique [0002] In distribution network planning, automatic segmentation of 10kV medium-voltage lines is an important concern, and its rationality is directly related to the amount of line loss and the number of households affected by line failures and power outages. At present, to measure the rationality of automatic segmentation of 10kV medium-voltage lines is mainly to analyze and compare whether the medium-voltage users, low-voltage users or loads in each segment are evenly distributed, but there is no parameter for quantitative evaluation. Contents of the invention [0003] In order to overcome at least one defect in the prior art, the present invention provides a rationality evaluation method for automatic segmentation of 10kV mediu...
