N-1 outage scanning system based on cooperation between overload cutting device and self-cutting device

Abstract

The invention relates to an N-1 outage scanning system based on cooperation between an overload cutting device and a self-cutting device and belongs to the technical field of electric power. The N-1 outage scanning system comprise a processor, a storer, a data analyzer, a data interface and other main devices and further comprises a topology module, a load flow calculation module, an N-1 module, a database module, a data analysis module, a data interface module and other main components. The data interface module acquires CIM file data and E file data from an SCADA system. The data analysis module analyzes a CIM file and an E file and then stores the analyzed CIM file and the analyzed E file into the database module. The topology module generates topology data according to equipment parameters and topology connection data. The load flow calculation module calculates grid load flow according to the topology data and grid operation data. The N-1 module performs N-1 outage scanning according to the topology data and the grid load flow data. Compared with the prior art, the N-1 outage scanning system has the advantages of being high in accuracy and practicability, quick and efficient.

Description

technical field

[0001] The invention belongs to the technical field of electric power, and in particular relates to an N-1 breaking and scanning system. Background technique

[0002] N-1 is an important content in power system stability analysis and calculation, and a very important safety check method in power grid dispatching operation. However, as the level of automation and intelligence in substations is getting higher and higher, self-cutting devices in substations in regional power grids are becoming more and more popular. The application of overload continuous switching devices and automatic switching devices can improve the level of dispatching automation, but it also has a certain impact on the traditional N-1 results, especially the order of automatic switching coordination among substations of different voltage levels. In the past, N-1, which did not consider the cooperation of the overload continuous cutting device and the self-cutting device, simply transferred...
