Research on electromagnetic compatibility test port model of smart high voltage equipment

Smart high voltage equipment (SHVE) is a core device for constructing the smart grid and the intelligent electronic device (IED) is a basic unit of SHVE, so the electromagnetic compatibility (EMC) of IED reveals the SHVE-EMC. From this point, this paper defines IED-EMC test models based on test ports concept. Four factors are put forward in order to ensure the validity of the IED-EMC test, and a discussion about conditions between carrying out the type test and the site test is provided. Finally, a suggestion for perfecting the test items is given to guarantee the integrity of the IED-EMC test based on a comparison between the IED-EMC test model and company standard of state grid corporation of China.
