Multicycle and multidimensional integrated maintenance scheduling optimization and safety analysis method

Abstract

The invention belongs to the field of maintenance scheduling evaluation and optimization in the power system and relates to a multicycle and multidimensional integrated maintenance scheduling optimization and safety analysis method. The method comprises the following steps: determining the moment requiring maintenance scheduling optimization according to the safety evaluation result after computing the generating capacity loss and the load supply adequacy at all the moments; carrying out the first optimization process: analyzing the variation of the index of generating capacity loss and determining the maintenance scheduling needing to be adjusted; carrying out the second optimization process: firstly analyzing and determining the bus load insufficient in load supply adequacy in a period of time according to the determined period of time of maintenance scheduling optimization; determining the dangerous branches which reduce the load supply adequacy; computing the correlation between the maintenance and the dangerous branches and determining the maintenance scheduling needing to be adjusted according to the correlation; and giving the final optimization and adjustment suggestion after analyzing all the adjustment conditions of the maintenance scheduling at the moment to be optimized. The method solves the problems in the existing methods.

Description

technical field [0001] The invention belongs to the field of electric system maintenance plan evaluation and optimization, and relates to a multi-period and multi-dimensional integrated maintenance plan optimization and safety analysis method. Background technique [0002] With the development of the power system, the scale of the power network is getting larger and larger, and there are more and more equipment under the jurisdiction of the dispatching center. All kinds of equipment have their own life cycles and need to be regularly scheduled for maintenance. In addition, due to infrastructure and technical transformation Necessary, it is necessary to arrange power outages of certain equipment from time to time. Arranging multiple equipment maintenance or power outages will cause changes in the operation mode of the power system, and a safety analysis of the maintenance plan is required. Sometimes, although the maintenance plan can pass the safety analysis, the maintenance...

AI Technical Summary

Problems solved by technology

[0003] At present, when the dispatching center arranges maintenance, it generally judges whether the maintenance plan will cause safety problems based on experience, and the more complex the network structure, the more inaccurate the empirical judgment

For the optimization of the maintenance plan, there are many studies on the optimization of generator sets at home and abroad, but there are few applications in practice.
