Problems solved by technology

[0003] However, the D5000 dispatching automation system cannot be combined with the five defenses of the substation, and can only conduct security analysis based on the main network model and real-time data
There is also a model of "integrated five preventions". This model can well solve the comprehensive error prevention analysis of remote control operations from the entire network to the specific interval of the substation. It is a better remote control operation error prevention solution. In this way, it is necessary to embed the main station part of the substation five-proof system into the dispatching automation system, which requires a lot of software changes, requires a large amount of funds, and also has the problem of unclear division of maintenance rights.

Embodiment Construction

[0020] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0021] A communication method between the main station of the D5000 dispatching automation system and the five-proof system of the substation. The error prevention method of the original substation five-prevention main station system is upgraded, and the communication software interface between the D5000 dispatching automation system and the substation five-prevention master station system is added to realize the communication between the dispatching automation system and the substation five-prevention system. Information interaction, the information interaction steps are:

[0022] (1) When the remote control interface of the main station of the D5000 dispatching automation system performs the remote control preset operation of the substatio...

Abstract

The invention relates to a way of communication between a D5000 scheduling automation master station system and a substation five-prevention system. The above mentioned way is a way of realizing remote control operation of whole network comprehensive misoperation-prevention by establishing an interface between the D5000 scheduling automation master station system security constraint and the substation five-prevention system. The software interface between the D5000 system master station security constraint and the substation five-prevention system provided by the invention is used to realize the real-time interaction of the data such as switch, knife-switch, net door, earth wire, and blocking information and so on between the two systems, and therefore safe operation of mutual compensation of security checking content of a macroscopic power grid level and a concrete substation level is realized.

Description

technical field [0001] The invention belongs to the field of electric power system regulation and control automation, in particular to a communication mode between a master station of a D5000 dispatching automation system and a substation five-defense system. Background technique [0002] The dispatching automation series products represented by D5000 are widely used in the State Grid, China Southern Power Grid and power grid dispatching control centers at all levels in various industries, effectively supporting the safe and stable operation of my country's UHV large power grid and reliable power supply for enterprises. In recent years, relying on advanced and stable products, it has defeated many well-known international companies with strong strength, successfully implemented the national survey projects of Sudan, Brazil, the Philippines, and the local survey projects, and through the implementation of the China Power Investment Circular Economic Zone Demonstration Project,...
