Surge Voltage Distribution Test for the Insulation Design at Kihoku Converter Station

Abstract

This paper presents the results of the surge voltage distribution test at Kihokuconverter station to verify the EMTP simulation modeling. The test voltage applied at the DC or AC transmission line entrance of the station. We calculated the voltage distribution of the converter station by EMTP taking the test conditionsinto consideration in addition to that of prior analyses. The simulated voltage distributions of either side of voltage application case agree very well withthose of test results. The accordance shows that the EMTP modeling used in the study was appropriate.
