Intelligent analysis and control method and system for main distribution network scheduling power failure plan

Abstract

The invention discloses an intelligent analysis and control method and system for a main distribution network dispatching power failure plan. The method comprises the steps of obtaining an overhaul plan and a power grid operation data section to realize system information integration; obtaining maintenance equipment based on the maintenance plan, and completing matching of the maintenance equipment and the system model; based on a power grid operation data section and a system model, performing main distribution integrated topology analysis, determining a power failure area influenced by equipment maintenance, forming a transfer strategy, and realizing intelligent arrangement of an operation mode; performing risk assessment on the generated transfer strategy to realize maintenance plan risk assessment; and managing and controlling the maintenance plans and proposing rearrangement suggestions for the maintenance plans with risks based on a risk assessment result, thereby realizing comprehensive management and control of the maintenance plans. According to the invention, information integration, operation mode intelligent arrangement, maintenance risk collaborative evaluation and maintenance plan comprehensive management and control of the main distribution network maintenance plan are realized, the effectiveness of the maintenance plan and the system reliability are ensured, andthe practical level of a service module is improved.

Description

technical field [0001] The invention belongs to the technical fields of dispatching automation and power distribution automation, and in particular relates to an intelligent analysis and control method and system for a dispatching outage plan of a main distribution network. Background technique [0002] With the rapid construction and development of large urban power grids, the interdependent operating characteristics of the main distribution networks have become increasingly prominent. First, the improvement in the demand for power supply reliability urgently requires the integration of major distribution and transportation plan adjustments. The main grid is in the process of formulating power outage plans Pay more attention to the impact on important users on the distribution side. When adjusting the operation mode of the distribution network, it is necessary to further consider the impact on the security and stability of the main network. Analyze the power outage plan and...

AI Technical Summary

Problems solved by technology

[0003] At present, dispatching outage plans are mostly filled in and circulated in the dispatching information management (OMS) system. Due to the lack of real-time operation status information of the power grid, untimely model updates, and the lack of effective verification methods, the generated maintenance plan may not be available during the dispatching execution stage. Applicable to the current mode of operation, and there are certain operational risks and poor usability

In the existing dispatch automation system, the analysis and optimization of the maintenance plan is independently implemented for the main distribution network, and the relevant research mainly focuses on the main network side, which is mostly an offline analysis mode. The consideration of important users on the distribution network side may lead to the risk of reduced power supply reliability of important users or repeated power outages for users, and the relevant business software system has not yet been seen on the distribution network side
