Networked power telecontrol communication method

Abstract

The invention discloses a networked power telecontrol communication method, which is used for solving the problems of the one-transmission multi-reception and information forwarding of power telecontrol information. The method adopts a technical scheme that: models of an IEC 61850 standard, such as common data models, data models, dataset models, selection control-prior-to-report-and-operation models and the like, are taken as bases, functional requirements of the power telecontrol communication are combined and then an IEC 61850-based power telecontrol communication model is established so that communications in a substation and between the substation and a control centre adopt IEC 61850, an MMS and Ethernet as a unique communication standard, a unique communication protocol and a unique communication platform so as to realize interoperations among different firm IEDs. The networked power telecontrol communication method radically solves the problems of the one-transmission multi-reception and information forwarding of the telecontrol information puzzling the field of power telecontrol for a plurality of years, and realizes the interoperations among the different firm IEDs and the unified configuration and management on equipment.

Description

technical field [0001] The invention relates to a power telecontrol communication method, in particular to a networked power telecontrol communication method based on IEC 61850 and MMS, and belongs to the technical field of communication. Background technique [0002] The power telecontrol system is an important part of the power dispatching automation system. It is an important means to realize the remote operation monitoring of the power system, implement frequency regulation, voltage regulation, power generation and load control, and dispatchers to control and adjust under accident conditions. Since the 1960s, the medium-term electric telecontrol technology represented by the "four remote" function has been developed until today. With the rapid development of semiconductor chip technology, computer technology and communication technology, telecontrol technology has been integrated into plant automation technology, and telecontrol has undergone essential changes in concept...

AI Technical Summary

Problems solved by technology

[0008] (1) Only considering the unification of the data format of specific equipment, its data transmission efficiency is not high, the amount of information released is small, and there is a lack of organic connection between subsystems;

[0009] (2) The data exchange capability between the factory station and the dispatcher is poor, only predefined data can be transmitted, and it is difficult to realize the new type of data exchange, and there is no information exchange capability between the factories and stations;

[0010] (3) There is no modeling and description of various actual objects inside SAS, and each manufacturer designs according to their own different understandings, which is the root cause of poor interoperability between different systems

[0011] (4) Adopt point-oriented data description method, lack of effective configuration tools and management methods, resulting in difficulties in equipment maintenance

[0012] (5) In the process of development and implementation, since it is a character-oriented protocol, not only the maintenance of the network connection needs to be considered, each layer of data packets must be defined in detail, but also the specific message format, high and low bytes must be dealt with, Its scalability and readability are far inferior to object-oriented protocols

[0013] (6) In the actual application process, the traditional communication mode and communication structure are still used. The main method is to improve the RTU, which only solves the problem of RTU network access, and does not fundamentally solve the telecontrol that has plagued the field of electric power telecontrol for many years. The problem of sending and receiving multiple messages and forwarding messages
