An Adaptive Modeling Method for Online Monitoring System of Secondary Equipment in Power System

Abstract

The invention discloses a CIM / E file-based self-adaptive modeling method of an online monitoring system for secondary equipment. The system comprises a CIM / E model subsystem, a communication subsystem, a real-time library and a history storage subsystem, wherein the CIM / E model subsystem is used for realizing the model analysis and conversion of an online monitoring file; the communication subsystem is used for realizing master-slave station communication functions such as request and response; the real-time library is responsible for operation data refreshing and model management; and the history storage subsystem is used for completing the history storage and query of models. According to the system, CIM / E is adopted to describe a data exchange way of a whole-network model of the online monitoring system for the secondary equipment, universal real-time communication service protocols of electric power systems are used for providing network transmission of the models, and self-adaptive modeling is carried out on the system on the basis of a model comparison rule algorithm. Through a specialized CIM / E format of the electric power systems, a template is used for realizing the self-adaptive modeling method of the online monitoring system for the secondary equipment, so that the efficiency and usability of the system are enhanced.

Description

technical field [0001] The invention relates to a modeling method of a power system model, in particular to an adaptive modeling method of a secondary equipment on-line monitoring system of a power system CIM / E file. Background technique [0002] Secondary equipment online monitoring main station (referred to as the main station) is deployed at the dispatching end, and the secondary equipment online monitoring sub-station (referred to as the sub-station) collects the operation data of the secondary equipment in real time, and uses the graphical interface to visually display the status monitoring of each secondary equipment The communication status of the secondary equipment is analyzed and processed to realize the online monitoring function of the secondary equipment information. [0003] Substations are deployed in conventional stations and intelligent stations, and there are differences in the model exchange methods between the two types and the master station. In convent...

AI Technical Summary

Problems solved by technology

Whether it is a conventional station or an intelligent station, the maintenance of the CIM / E file can be carried out at the substation. The main station uses the CIM / E file as the model exchange file, and the main station can complete the model preparation by calling the file, which solves the problem The problem of inconsistent access methods of different types of sub-stations, the modeling method is unified, and the idea of ​​source-end maintenance of the secondary equipment model is followed
