Automatic modeling method of direct current transmission project network topology

Abstract

The invention discloses an automatic modeling method of direct current transmission project network topology. The method comprises loading a direct current project module according to direct current project structure information to generate a direct current project main connection schematic diagram, extracting a sub-connection diagram template, a device model, and circuit components according to the direct current project main connection schematic diagram, and then generating a direct current project device information file; configuring parameters and a position for a lightning arrester according to the direct current project main connection schematic diagram, and then generating a lightning arrester schema configuration information file; and completing the modeling of the direct current project network topology equipped with the lightning arrester and the generation of an equivalent circuit diagram by adopting the direct current project main connection schematic diagram as a template and combining the direct current project device information file and the lightning arrester schema configuration information file. The automatic modeling method of the invention presets a typical direct current project network topology module, various device types and equivalent models, and instantiation applications of the direct current project can be completed by just selecting a device type and a parameter configuration by users. Workload amount of the direct current project network topology equivalent and modeling is greatly reduced, and direct current project modeling efficiency is improved.

Description

technical field [0001] The invention belongs to the field of high-voltage direct current transmission system analysis, and in particular relates to an automatic modeling method for network topology of a direct current transmission project. Background technique [0002] my country's power grid is in a period of rapid development, and has now entered the stage of transition from a large regional power grid to a national interconnected power grid. With the implementation of the national networking project, DC transmission technology will play a leading role in the west-to-east power transmission and national networking. At the same time, the voltage level of DC projects is gradually increasing from 500kV to 800kV, and even has a tendency to develop to a higher voltage level. The DC operation mode is gradually developing from single-circuit to double-circuit. A series of technical and safety issues, such as more complex DC system failures, more serious losses and system problems...

AI Technical Summary

Problems solved by technology

Since the two softwares only provide the most basic circuit components, to model DC engineering network topology, users first need to be particularly familiar with the system component library and DC transmission characteristics, and at the same time carry out reasonable equivalent modeling of DC engineering equipment , and secondly, it is necessary to convert the complicated engineering data into corresponding circuit component parameters, and the workload is very heavy

At the same time, the more complex the engineering wiring, the greater the workload of modeling and the more prone to errors
