Method for realizing fast and automatic modeling of transformer substation IEC 61850 by adopting XML information recombination

Abstract

The invention provides a method for realizing fast and automatic modeling of a transformer substation IEC 61850 by adopting XML information recombination, which is applied to IED modeling of space layers in a digital transformer substation and a traditional transformer substation by adopting IEC 61850 communication. The method comprises the following steps of: recombining the IED information by adopting XML, and providing an IED information standardization interface; editing and setting the standardized XML files; loading an embedded minimum model which accords to the IEC61850 standard; appointing an sAddr information format in advance, automatically adding sAddr information and leading out an ICD model file; analyzing the led-out ICD model file by the IED, and automatically extracting the sAddr information, and automatically mapping model leafage nodes to a real-time database according to the sAddr information; and enabling the information of the real-time database to normally communicate with station control layer equipment by the IED through adopting an IEC61850 protocol. The model collocation can be set by engineering personnel according to actual engineering. Therefore, the invention greatly shortens the time for generating the IEC61850 model, improves the efficiency of production and regulation and is convenient for 61850 engineered actualization and generalization.

Problems solved by technology

Since the implementation of IEC 61850 in China, most of the model generation still adopts manual modeling, and many links require manual intervention. Due to the participation of human factors, it is easy to make mistakes, and the project cycle is long, which limits the function of IEC 61850 At the same time, manual editing of intelligent electronic device capability description ICD model files also has the following disadvantages:

[0005] 1) It takes a lot of time to learn the substation configuration description language SCL

[0006] 2) The substation configuration description language SCL describes the model in a very flexible manner, and manual editing is not conducive to model standardization

[0007] 3) Due to the complexity of the model, the editing workload o
