The invention provides a power distribution network reliability assessment repair time parameter modeling method and equipment, and medium. The method comprises the steps of acquiring historical dataof faulted equipment of a power distribution network; according to a preset equipment repair feature dividing repair time of the faulted equipment, and building a repair time model; statically analyzing the historical data according to the repair time model and a preset fault statistical feature, and computing the duration of each repair time period in the repair time model; and computing the repair time reliability parameter of the power distribution network according to the duration of each repair time period. Through dividing and modeling the repair time of the faulted equipment, and computing the divided repair time, the repair time parameter of reliability assessment within the certain time period can be accurately computed, the accuracy of the equipment repair time parameter can be improved, and the error of the power distribution network reliability assessment can be reduced.
Description
technical field [0001] The invention relates to the technical field of distribution network reliability evaluation, in particular to a distribution network reliability evaluation repair time parameter modeling method, equipment and media. Background technique [0002] The distribution network undertakes the important task of transmitting electric energy from the power supply or transmission network to users of different voltage levels, and is directly connected to users, which has a great impact on the reliability of power supply. Statistics show that about 80% of power outages are caused by power distribution system failures. Therefore, it is very important to evaluate the reliability of distribution network accurately and quickly. The reliability parameters required for reliability evaluation are mainly divided into two categories: failure probability parameters and repair time parameters. These two types of parameters need historical fault statistical sample data to be ...
