Maintenance plan optimization method and system containing key maintenance

Abstract

The invention provides a maintenance plan optimization method containing key maintenance. The method comprises the steps of obtaining a current maintenance plan, maintenance increment risk data and a fault set which are correspondingly generated based on a maintenance influence domain; screening out anticipated faults meeting preset conditions from the maintenance increment risk data, and further receiving tide sensitivity formed by all anticipated fault elements in a fault set during maintenance operation of each anticipated fault based on the condition that the power grid is recovered to a full-wiring operation mode; and sorting all the received power flow sensitivities according to a predetermined rule, determining the maintenance of a corresponding expected fault as key maintenance according to a sorting result, and further adjusting the current maintenance plan according to the key maintenance to form a new maintenance plan. The invention also provides a maintenance plan optimization system containing key maintenance. By implementing the method, the problems that in the prior art, data are numerous, the making time is too long, and the fault equipment maintenance plan arrangement is unreasonable can be solved.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a maintenance plan optimization method and system including critical maintenance. Background technique [0002] The purpose of electrical equipment maintenance is to ensure the high reliability of equipment operation, which is an important task in the daily operation of the power grid. When electrical equipment is overhauled, along with changes in the power grid topology and operation mode, the operational risks of the system also change. Especially during the overhaul period, the redundancy of power grid equipment decreases significantly, which brings more severe challenges to the stable operation of the system. [0003] In view of the short maintenance time, the high real-time requirements for risk assessment of regional power grid operation, and the need to combine online risk assessment functions, it is urgent to arrange scientific and reasonable maintenanc...
