Abstract
The overcurrent turn-off test is one of the transient state test of voltage sourced converter based high voltage direct current transmission (VSC-HVDC) valves, which is to verify the design validity and the short circuit across state stress tolerance of valves. The test method of the overcurrent turn-off test was investigated. The stresses related to the short circuit across state were analyzed, then the equivalent test methods and test circuit were designed. At the end of this paper the contrast of the stresses waveforms between the ones in actual operating state and the ones in test circuits was shown, combined with the analysis of equivalence of key stresses, the equivalence of test methods and the test circuits was proved.
