Main and distribution network linkage power failure analysis method and system

Abstract

The invention discloses a main and distribution network linkage power failure analysis method and system. The method comprises the steps of obtaining a main network maintenance plan and a distributionnetwork maintenance plan; analyzing the number of first distribution network feeders which are influenced by the main network maintenance plan and need to be powered off and the number of second distribution network feeders which are influenced by the distribution network maintenance plan and need to be powered off; analyzing the number of partial feeders capable of transferring power supply in the first distribution network feeder number; and calculating a difference value between the first distribution network feeder number and the partial feeder line number, calculating a ratio of the second distribution network feeder number to the difference value, and judging whether the main distribution network adopts linkage power failure overhaul or not according to the ratio. By obtaining the main network maintenance plan and the distribution network maintenance plan, whether the main and distribution networks need linkage power failure maintenance can be automatically judged, the analysisand decision efficiency is high, the main and distribution network maintenance can be arranged as a whole, the comprehensive power failure management level is improved, the power failure time is reduced, the power consumption experience a user is improved, and the power consumption business environment is optimized.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution management, and in particular relates to a main distribution network linkage power failure analysis method and system. Background technique [0002] As my country's economy shifts from high-speed development to a new stage of high-quality development, the society's requirements for power supply reliability are getting higher and higher. Reducing power outage time, improving user experience in electricity use, and optimizing the business environment for electricity use have become a major challenge for power supply companies, and higher requirements have been placed on the management level of power supply companies. On the one hand, power supply companies must strengthen the construction of grid structures, and on the other hand, they must start with comprehensive power outages to reduce the impact of planned power outages. [0003] The "master-distribution linkage" is a nece...

Problems solved by technology

Due to the current lack of relevant tool support, the maintenance management personnel of power supply enterprises can only manually arrange and analyze the main and distribution network maintenance plans. The workload is quite large, time-consuming and labor-intensive, and it is easy to miss coordination points

The specific performance is: the main and distribution network maintenance plans of power supply enterprises are managed by different personnel, the main network maintenance management personnel do not know the situation of the distribution network lines, and the distribution network maintenance management personnel do not know which main network maintenance plans will lead to distribution network power outages , When making maintenance plans, we can only communicate through Excel tables and emails. There are often hundreds or thousands of maintenance plans, high management costs, low communication efficiency, and difficult analysis. It is difficult to make overall arrangements for main and distribution network maintenance plans. It is difficult to analyze the improvement effect of main and distribution network cooperation on power failure and how many potential cooperation points there are
