Embodiment 1

[0023] like figure 1 As shown, the non-intrusive relay protection system closed-loop test system involved in this embodiment includes: a test control module, a test analysis module, a network communication module and a data storage module, wherein: the test control module receives manual test instructions and outputs them to the network Communication module, data storage module and data analysis module; according to the protection system under test specified in the test instruction, call the fault report of the protection device under test in the data storage module as a test case; support the test case and test of the called data storage module The results are compared and displayed visually. The network communication module receives fault reports from manual testing and protection devices in case of power grid accidents through the MMS network, and outputs them to the data storage module as test cases for non-invasive testing. Send the test instructions from the test contro...

Abstract

The invention relates to a system and a method for testing a relay protection system in a closed loop non-invasively in the technical field of intelligent substations. The system comprises a test control module, a data analysis module, a network communication module and a data storage module. Non-invasive testing is completed under the precondition that no connecting wire of the protection system is changed through a merging unit, a protective device, an MMS (Multimedia Messaging Service) communication port and an SV communication port; meanwhile, automatic evaluation for test results and complete management for comparison files of the test results of the relay protection system to be tested can be realized, so that the testing efficiency of the relay protection system for an intelligent substation is effectively improved, the probability of equipment inactivation once due to the inspection of the protective device is reduced, and the security of the power system is improved.

Description

technical field [0001] The invention relates to a test system in the technical field of intelligent substations, in particular to a test case-based non-invasive relay protection system closed-loop test system and method. Background technique [0002] The intelligent substation automation system is based on the IEC61850 system, and the concept of the process layer is proposed. The process layer IED device (Intelligent Electronic Device, intelligent electronic device) merging unit and intelligent terminal emerge as the times require. The on-site installation of process-level IED devices close to primary host equipment (transformers, circuit breakers) reflects the development trend of future smart substation construction. However, the distributed arrangement of process-level IED devices brings a lot of inconvenience to conventional testing methods . The so-called conventional test mode is to manually build a test environment near the IED device, disconnect the connection betwe...
