Double-engine-driving-based universal processing method and system for international electrotechnical commission (IEC) 103-based master station/substation protocols

Abstract

The invention discloses a universal processing method for unified object oriented process (OOP) for dozens of kinds of international electrotechnical commission (IEC) 103-based failure information system master station / substation transmission protocols at present, and is applied to the substation equipment of a power grid failure information system. Because the failure information system develops unevenly in China and construction of power communication networks throughout the country starts inconsistently, the conventional failure information system master station / substation protocols in China are expanded and reduced in a plurality of ways on application layers adopting IEC103, a connection-based link mode and a connectionless link mode are adopted, and various combinations of application and links further cause the great number of actually online master station / substation protocols. The invention provides a link processing method for unifying the two link modes and a universal application layer processing method for the IEC103-based failure information system master station / substation protocols. On such a basis, data interaction is organized by constructing the link and the dual-drive engine interface of the application layer, a high-efficiency algorithm and a data structure are provided, and the problem about the unification of the IEC103-based master station / substation transmission protocols of substations is finally solved. On such a basis, universal server software for IEC 103-based master station / substation transmission can be developed, the data interaction of IEC103-based failure information systems can be finished by the universal software and various master stations in China, and the universality and maintenance stability of the substation products can be enhanced.

Description

technical field [0001] The present invention is applied in the field of electric power system dispatching automation, abstracts the current domestic mainstream protocols of various fault information systems based on IEC103, proposes a general implementation method that can be processed in a unified manner, and solves the protocol processing barrier of domestic application of fault information substations. Background technique [0002] Due to the unbalanced development of fault information systems in China, there has been no unified master-substation protocol specification. As a transitional solution before the implementation of IEC61850, all localities use the IEC103 protocol as the application layer specification for the transmission of master and substations, and various extensions or reductions have been made according to the understanding of the fault information system and the local construction level of the fault information system. In addition, due to the different st...

Problems solved by technology

Due to the expansion of these different application layers and the collocation of the link layer, there are currently dozens of master-substation protocols in China, and even the local survey, intermediate survey, and network survey of the same province are completely different protocols. Unified substation product creates a big hurdle

Simultaneously developing and maintaining different software products, training engineers who are familiar with local protocols is a great burden for enterprises
