Though IEC 62501 was already published in 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, 2]. In this paper, all the type tests required by IEC 62501 are discussed for a Modular...
VSC technology is now well established in HVDC and is, in many respects, complementary to the older Line Commutated Converter (LCC) technology. Many advantages have been claimed for VSC technology in HVDC, including the smaller site footprint. On the other hand, VSC HVDC stations have higher power losses than LCC stations. Although the relative advantages and disadvantages are well known within the...
