An automatic analysis method for power supply capacity of distribution network

Abstract

The invention provides an automatic analysis method for the power supply capability of a distribution network, comprising the following steps: basic data acquisition: acquiring relevant data information by establishing data interfaces with major related systems; data processing and analysis: processing the ring network information through distribution network lines Analyze and establish the connection relationship between the distribution network lines powered by substations or 10kV busbars in the area and the distribution network lines powered by substations or 10kV busbars outside the area; at the same time, combine the load data information of substations, 10kV busbars and distribution network lines to analyze the dependence of distribution network lines Analysis of ring network connection relationship will cause overload after power supply transfer; combined with the number of users of 10kV distribution network lines and ring network connection relationship, analyze the number of users transferred to power supply; comprehensive display of data: After entering the site and settings in the relevant area on the interface, The system automatically analyzes and processes the data and presents the results to the user.

Description

technical field [0001] The invention relates to the field of distribution network management methods, and more specifically, to an automatic analysis method for power supply capacity of a distribution network. Background technique [0002] Due to the grid structure of the main grid, it often occurs that multiple substations or 10kV busbars in a certain area need to limit the load. For the reliability of power supply for users, it is necessary to transfer part of the load to other substations outside the area through distribution lines. And 10kV bus for power supply. When the distribution network dispatcher executes the power supply transfer, it is necessary to manually check the connection relationship between the distribution network lines and the distribution network lines supplied by the substation or 10kV bus outside the area one by one, and also need to consider whether the opposite substation or the main transformer will be overloaded after the power transfer And othe...

AI Technical Summary

Problems solved by technology

The above traditional methods are difficult to quickly provide a power transfer plan for the distribution network lines in the area when the power grid needs to limit power in an emergency, resulting in untimely load control and potential safety hazards for the operation of power grid equipment.
