Method for converting SCD (Substation Configuration Description) model into dispatching center CIM (Common Information Model)

Abstract

The invention discloses a method for converting an SCD (Substation Configuration Description) model into a dispatching center CIM (Common Information Model), which is characterized by comprising the following steps of: (1) establishing a complete SCD model; (2) deleting models which are not needed by a primary station and minimizing the SCD model; (3) realizing mapping between the SCD model and the CIM; (4) deriving a single line drawing file in an SVG (Scalable Vector Graphics) format by the CIM and meanwhile establishing an association relationship between an SVG single line drawing and the CIM; (5) after the primary station obtains the CIM and the SVG single line drawing file of a substation, testing validity; and after passing the test, splicing the models and meanwhile establishing a database by the association relationship between the SVG single line drawing and the CIM. The invention can automatically explain real-time data, reduce repetitive time-consuming work which easily causes mistakes, such as manual signal check, and the like, and meet the maintenance requirement of a source terminal directly by adopting a self-describing model established by the substation.

Description

technical field

[0001] The invention belongs to the field of power system automation, and more precisely relates to a conversion method from a substation automation system SCD (Substation Configuration Description, substation configuration description) model to a dispatch center automation system CIM (Common Information Model, public information model). Background technique

[0002] After nearly ten years of theoretical research and practical construction, the application of IEC 61850 and 61970 in digital substation automation system and master station dispatching automation system has gradually matured. However, the models and communication protocols adopted by IEC 61850 and 61970 are quite different, and IEC has not proposed the fusion method between the models, nor has it formulated the communication connection method between the substation and the main station. Since the release of IEC 61850 and 61970, issues related to the coordination of IEC 61850 and 61970 have receiv...
