Intelligent substation and regulation and control center coordinative modeling method

Abstract

The invention discloses an intelligent substation and regulation and control center coordinative modeling method, comprising: standardizing the function of a system configuration tool of a substation automatic system; standardizing and expanding device and signal descriptions in an SCD (Substation Configuration Description) file; expanding a measurement model in a CIM / E (Common Information Model / E language) file; making mapping rules of IEC 61850 and IEC 61970 models; by reference to requirements of relay protection information standards and monitor system information standards, performing classified management on the information; automatically exporting the CIM / E file required by a regulation and control center on the side of an intelligent substation by using the system configuration tool, and performing checking; and providing the CIM / E model file for the regulation and control center in an offline or online manner and executing model splicing and storage processing. According to the method, the mapping and conversion from the 61850 model to the 61970 model are finished, the model and information sharing is realized, the model maintenance workload of the regulation and control center is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a coordination modeling method for an intelligent substation and a control center. Background technique [0002] The International Electrotechnical Commission has successively formulated the IEC61970 standard and the IEC61850 standard, which are respectively used for the internal system interconnection and system integration of the control center, as well as the communication architecture and implementation standards in the substation. The substation follows the IEC61850 standard to model the primary equipment, secondary equipment and the relationship between primary and secondary equipment in the substation. The substation configuration description (SubstationConfigurationDescription, SCD) file is used as the basis for maintenance and management of the substation model; the control center adopts The IEC61970 standard uses Common Information Model (CIM...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a coordinated modeling method between the smart substation and the control center, aiming at solving the difficulty in sharing the grid model between the substation and the control center due to the difference in modeling standards between the two heterogeneous systems existing in the current smart grid. The maintenance workload is large, and the equipment naming and signal description of the dispatching control system and the substation automation system are not unified, which restricts the level of information exchange between each other and limits the collaborative interaction between the control center and the substation application
