Problems solved by technology

Due to the hierarchical and partitioned management mechanism of the power grid, when the planner arranges the maintenance plan, the maintenance of the main distribution network equipment has a major impact on each other. Analyzing co-processing, causing repeated outages
For example, the main network equipment maintenance will affect the power loss of the distribution network. When the maintenance method is arranged, only the safety of the main network side is considered, and the transfer capacity of the distribution network cannot be considered, resulting in high-risk operation of the distribution network side. Users bring a certain risk of power outage
[0004] Since the maintenance application forms submitted by each work area are isolated, the associated and cross-effects of equipment maintenance are unpredictable, including repeated power outages in a short period of time, and high-risk operation of the power grid. At the same time, centralized maintenance at the same time also brings certain challenges to power grid operation and staffing. pressure

Embodiment Construction

[0065] A method and system for optimizing the time window of a coordinated maintenance plan for main equipment will be described in detail below with reference to the accompanying drawings.

[0066] like figure 1 As shown, a method for optimizing the time window of a main equipment collaborative maintenance plan of the present invention includes the following steps:

[0067] Step 1. Based on the data fusion technology, establish an integrated model of the main and equipment collaborative analysis, and input the current maintenance plan. Specifically, the maintenance plan includes the maintenance start time, the maintenance duration, and the human and material resources occupied by the maintenance. The integrated model of the main and auxiliary cooperative analysis of the present invention can realize the cross-system data sharing in combination with the transparent access service.

[0068] Step 2: Collect the real-time operation data, load forecast data and historical operat...

Abstract

A method and system for optimizing the time window of the main-distribution coordinated maintenance plan. Aiming at the problem of repeated power outages and affecting the safe operation of the power grid caused by the cross-correlation between multiple maintenance plans in the power grid maintenance window, a method and system that considers safety constraints, mutual exclusion characteristics, and Based on the evaluation index of various factors such as power supply reliability, the multi-objective optimization model of the maintenance time window is established with the goal of the infeasibility of mutual exclusion of maintenance and the minimum degree of violation of the resource constraints of the maintenance company, and the simplex linear programming method is used to solve it, forming Maintenance plan optimization strategy for master-partner coordination within the maintenance time window. The invention is applicable to the field of multi-constraint target optimization of electric power system maintenance plans, takes the minimum impact of multiple maintenance plans on the power grid within a time window as an index, provides a method and system for reasonable arrangement of maintenance plans, and ensures safe and reliable operation of the power grid.

Description

technical field [0001] The invention belongs to the field of power system dispatch automation, and in particular relates to a method and a system for optimizing a time window of a coordinated maintenance plan for main equipment. Background technique [0002] Equipment maintenance is a regular business in the power system, involving many professional fields such as planning, transportation, and scheduling. Each work area submits a maintenance application according to the equipment operation. The dispatching and operation departments adjust the method based on the safety of the power grid and the reliable power supply of users. The constraints and goals considered by different professionals are inconsistent, and there is a lack of a unified platform for the maintenance of each process of the maintenance business. Integrated analysis makes it impossible to optimize the maintenance business. [0003] Because the power system is a whole network structure with interconnection of ...
