Mapping method for SCL model and CIM model

Abstract

The invention discloses a method for implementing lossless mapping of a 61850Ed2.0SCL model and a 61970CIM model on the basis of expanding the 61970CIM model. The method comprises the main steps of: electrical equipment container model mapping, non-electric function (sub function) model mapping, conducting equipment model mapping, universal equipment model mapping, topological relationship mapping, intelligent electronic equipment mapping, primary and secondary equipment association establishment, intelligent electronic equipment logic node mapping, and intelligent electronic equipment measurement mapping. The method implements complete mapping of the SCL model and the CIM model so as to fulfill the aim of lossless conversion of SCL and CIM. Mapping of the SCL and CIM models is implemented in a mode of expanding the CIM model, a main body structure of the CIM model is not modified and changed, and information is attached to the CIM model only in a conversion and expansion mode. Therefore, modification impact to an existing operating system based on the CIM model is also greatly reduced, and influence on system operation is reduced.

Description

technical field [0001] The invention relates to the exchange of substations, main stations, and dispatching models, in particular to a method for realizing the lossless conversion between substation SCL models, main stations, and dispatching CIM models based on an expansion method, and belongs to the technical field of electric power system automation. Background technique [0002] At present, the construction of smart substation system is based on the IEC 61850 standard. With the construction and development of smart grid and the utilization of renewable energy, IEC 61850 is no longer limited to the application in the substation. It should be expanded appropriately and consider more applications to meet the needs of current technologies. development needs. The scope of application of the 61850Ed2.0 series of standards revised based on Ed1.0 has been expanded beyond the scope of substations. The name of IEC 61850Ed2.0 was changed accordingly to power automation communicatio...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the problem that the conversion between the SCL model and the CIM model is incomplete due to the mapping difference between the existing SCL model and the CIM model, and formulates a mapping method by analyzing the structure, composition and content of the SCL and CIM
