Improving method and system for lean management of multi-cycle integrated outage plan of large power grid

Abstract

The invention relates to an improving method and an improving system for lean management of a multi-cycle integrated outage plan of a large power grid. The method comprises the steps of determining a positive and negative correlation of main equipment in the power grid by analyzing a power grid topological structure, thus ensuring achieving one-outage and multi-availability of the main equipment and avoiding the occurrence of related outages; predicting a coupling relation between data and outwards transmission channels, a power grid safe operation rule and historical trend data information by analyzing contribution of a clean energy base, and determining the best outage time slot range to ensure a clean energy accommodation capacity; determining equipment groups by analyzing an incidence relation between power grid tie-line data and tie-lines and by one-ticket type circulation processing, and finding a reasonable outage time slot; and reminding of repeated outage requests caused by continuous conventional overhauling by analyzing and comparing historical outage plans, thus reducing unnecessary requests. According to the method and the system provided by the invention, a management model of the multi-cycle integrated outage plan of the large power grid which is based on the power topological structure and meets requirements of the safe operation rule and requirements of accommodation of clean energy is built, so that a lean management level of the outage plan is effectively enhanced.

Description

technical field [0001] The invention relates to a power grid operation management method, in particular to a method and system for improving the lean management of a multi-period integrated power outage plan for a large power grid. Background technique [0002] The power outage plan of power equipment is one of the most important tasks in power production. Scientific and effective management of power outage plan for power generation and transmission equipment is an important measure to ensure system security and control power grid risks. The current mode of formulating power outage plans based on experience has been difficult to adapt to the company's lean requirements for equipment management under the new situation, especially under the trend of increasingly complex power grid topology, there are complex interactions between different equipment, and the original system The outage plan management model has been difficult to adapt to the new situation.
