Factory-like intelligent maintenance system for secondary equipment of intelligent substation

Abstract

The invention provides an intelligent substation secondary equipment factory intelligent maintenance system comprising a virtual simulation module which is used for providing SCD visualization, virtual-to-real simulation test, virtual-to-virtual simulation test, configuration file management and control, protection information monitoring and auxiliary safety measure functions; the automatic test module is used for automatic test report generation, automatic test result output, automatic test data display, experimental process control, test template generation and engineering parameter generation; the full-station simulation module is used for generating a simulation test report, outputting a simulation test result, carrying out experiment control, carrying out simulation operation, setting test parameters and carrying out substation modeling; the communication analysis module is used for abnormal alarm, parameter setting, MMSClient, MMSServer, message analysis and communication monitoring; and the public service part is used for realizing data sharing and high integration of the system. Operation and maintenance efficiency can be improved, power grid operation efficiency and reliability are improved, debugging and testing efficiency is improved, and remote synchronous visualization of field testing is achieved.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a factory-like intelligent maintenance system for secondary equipment of intelligent substations. Background technique [0002] With the wide application of information technology and the continuous deepening of smart grid-related technology research, the construction of smart substations has entered a period of rapid development. Since 2012, almost all the substations newly constructed by the State Grid Corporation of China have adopted the smart substation mode. After a period of trial operation, the substations newly put into operation in the early stage are gradually handed over to the operation and maintenance department to enter the normal maintenance and management stage. With the completion of the operation and maintenance handover work of the substation of the power grid company, the maintenance and repair work of the smart substation will eventually be carried out ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned tester can also test the protection function, the test lacks systematicness and integrity, cannot simulate the on-site test environment, and cannot directly reflect the external interconnection of the equipment under test or the interval, and cannot meet the requirements of the system in the process of operation and maintenance, reconstruction and expansion. The testing process is limited to functional and performance testing, and lacks consideration of the entire process of operation, maintenance, renovation and expansion, and cannot effectively improve the efficiency of on-site testing.
