Though IEC 62501 has been published since 2009 to define the requirements of the electrical type testing for the Voltage Sourced Converter (VSC) valves for High Voltage Direct Current (HVDC) transmission, so far very few papers have really discussed the test methods for VSC valve nor disclosed any test results [1]. In this paper, one of the important type tests required by IEC 62501, the operational test, is discussed for Modular Multi-level Converter (MMC)-based VSC valves based upon the half-bridge topology. The test methods for both the recommended preliminary tests and the type tests are discussed and the corresponding simulating and testing results are presented.
