Method and device for intelligent substation auxiliary system modeling

Abstract

The invention provides a method for intelligent substation auxiliary system modeling. The method for intelligent substation auxiliary system modeling comprises the steps that S1, a physical device of an auxiliary control system is arranged to be a logic device; S2, a plurality of logic nodes are set for the logic device and each logic node comprises a public contact; S3, in the auxiliary control system, modeling is conducted on each unit of each logic node of the physical device so that a logic node object can be formed, data belonging to the same unit object are stored in different logic node objects, logic node object type extension can be conducted or logic node object types can be newly established; S4, a dataset can be established according to the data of the logic nodes of the auxiliary control system. The invention further discloses a device for intelligent substation auxiliary system modeling. According to the method and device for intelligent substation auxiliary system modeling, modeling is conducted in a unified mode, extension is facilitated and management is simplified.

Description

technical field [0001] The invention relates to the field of system modeling, in particular to a method and device for modeling an auxiliary system of an intelligent substation. Background technique [0002] The International Electrotechnical Commission TC57 formulated the IEC61850 communication standard on the basis of summarizing the previous communication protocols. The communication standard unifies the modeling of the objects in the substation automation system, adopts object-oriented technology and the abstract communication service interface (ACSI) independent of the network structure, enhances the interoperability between devices, and can be used between devices of different manufacturers seamless connection between. This standard has the characteristics of flexible configuration, high reliability, and strong security, and represents the future development direction of substation automation technology. [0003] The core of the IEC61850 communication standard is "mo...

AI Technical Summary

Problems solved by technology

Since the implementation of IEC61850 in China, most of the substation auxiliary system model generation still has no unified modeling method, and many links require manual intervention. Due to the participation of human factors, errors are prone to occur, and the project cycle is long, which limits the IEC The large-scale promotion of 61850 functions, and the ability to edit intelligent electronic device description ICD model files also have many shortcomings

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

[0006] 2) The way of substation configuration description language SCL to describe the model is very flexible, which is not conducive to the standardization of the model;

[0007] 3) Due to the complexity of the model, the editing workload of the intelligent electronic device capability description ICD file is heavy
