Self-description realization method of IEC61850 standard

Abstract

The invention relates to a self-description realization method of an IEC61850 standard, belonging to the application field of the international substation communication network and system standard (IEC61850) to a substation automation system and solving the defects of ambiguous description, heavy workload, and the like existing in the prior art. The method comprises the steps: (1) obtaining capability self-description files of various devices from the devices of the substation; (2) systematically configuring, treating various signal descriptions of the substation according to the capability self-description files of the devices and a system scale description file and generating a substation configuration description file uniform in the whole substation; and (3) downloading the uniform substation configuration description file to the devices. The invention unifies the signal description of the devices, can definitely identify all signals, lightens the workload and facilitates the practical application of the IEC61850 standard.

Description

【Technical field】 [0001] The invention relates to the application field of the international standard "Substation Communication Network and System" (IEC61850) in the substation automation system, in particular to a model self-describing method of the IEC61850 standard in engineering implementation. 【Background technique】 [0002] The IEC61850 standard is the latest series of standards of "Substation Communication Network and System" formulated by the International Electrotechnical Commission TC57 working group to solve the interoperability problems faced by the substation automation system. This standard is supported by most mainstream manufacturers at home and abroad, and has become the only unified standard in the field of substation automation in the world. The IEC61850 standard defines a self-describing model, and the client can automatically obtain the signal name according to the model and its self-description without having to check the communication protocol signal p...

Problems solved by technology

However, the primary equipment in the current substation, such as circuit breakers, isolating switches, transformers and other digital intelligent equipment is still immature, and many signals can only be transferred and mapped into signal models through the measurement and control device, but it is difficult for the measurement and control device to determine the site connection of each project. For signal description, only the general input and output model (GG...
