Study the adaptability test and protective measures of relay protection devices in a compound electromagnetic environment

In the new generation of smart substations, the integration of smart high-voltage equipment and the localization of smart electronic devices are the new development directions. The operating environment is also more severe and complicated, and testing with reference to the existing EMC standards cannot fully meet the requirements of the operating environment of the secondary protection equipment. Therefore, based on GIS electromagnetic transient reality platform, this paper carries out a large number of port disturbance tests and adaptability tests of local protection devices in complex electromagnetic environment, and puts forward electromagnetic protection measures in adaptability test, which provides a new method for electromagnetic compatibility performance verification of local protection devices.
