Distribution network running health status evaluation method

Abstract

The invention discloses a distribution network running health status evaluation method. The method includes: selecting indexes required for distribution network running health status evaluation; establishing scoring standards used for calculation of the selected indexes, setting corresponding index types for the indexes according to all index scores of calculation, combining scoring standard settings and the corresponding index types to construct a distribution network planned-running evaluation model, and setting weights of all the indexes in the model; inputting actual power network runningindexes of detection into the distribution network planned-running evaluation model for evaluation, and obtaining score values of all the indexes; and obtaining a total score value of the actual indexes of distribution network running according to the score values of all the indexes, and determining health status of distribution network running. According to the method, the indexes closely relatedto distribution network planned-running are selected, precise and highly efficient evaluation can be realized, a good foundation is laid for health running of a distribution network, the effective quantitative standards are provided, and various problems existing on the distribution network are accurately discovered in time.

Description

technical field [0001] The invention relates to a method for evaluating the operating health state of a distribution network, which belongs to the technical field of power system optimization. Background technique [0002] In order to accelerate the construction and transformation of distribution network, the National Energy Administration has formulated an action plan for the construction and transformation of distribution network. It is planned that by 2020, the level of intelligent construction and application in the central urban area will be greatly improved, the reliability rate of power supply will reach 99.99%, the power outage time of users will not exceed one hour, and the quality of power supply will reach the international advanced level; the power supply capacity and power supply safety level in urban areas will be significantly improved, and the power supply The reliability rate reaches over 99.88%, the average power outage time of users does not exceed 10 hour...
