Regional power grid maintenance plan generation method and system

Abstract

The invention discloses a regional power grid maintenance plan generation method and a system. The method comprises the following steps: randomly generating M maintenance schedules according to a preset rule; performing transient stability simulation calculation on each of the M maintenance schedules; performing whole-process dynamic simulation calculation on each of the M maintenance schedules; calculating the fitness corresponding to each of the M maintenance schedules according to the transient stability simulation calculation result and the whole process dynamic simulation calculation result; judging whether one or more fitness meeting a preset fitness threshold value exists in the fitness corresponding to the M overhaul plans, and if yes, outputting the overhaul plan meeting the preset fitness threshold value; the method and the system have the advantages of transient simulation and dynamic simulation, take timeliness and accuracy into consideration, and can quickly and effectively make a more complex regional power grid maintenance plan.

Description

technical field [0001] The invention relates to the field of electric power technology, and more particularly, to a method and system for generating a regional power grid maintenance plan. Background technique [0002] The formulation of monthly maintenance plans for regional power grids is relatively complex; it may be caused by excessive and unreasonable initialization operation methods, which may lead to combined explosion problems in the evaluation and verification calculation work, and more likely to encounter transient simulation distortion and other simulation calculations that are difficult to identify risks. luck situation. On the whole, the formulation of regional power grid monthly maintenance plan is a multi-constraint and multi-dimensional optimization problem. SUMMARY OF THE INVENTION [0003] In order to solve the problem that the regional power grid monthly maintenance plan is relatively complex in the background art, the present invention provides a regio...
