Abstract

While Part 1 of the DIN EN 62751 series presents the general principles for calculating the power losses of valves in any converter topology, this Part 2 contains a detailed description of the procedure for calculating the power losses in the valves of an HVDC system based on the "modular multilevel converter", where each valve in the converter consists of a number of independent voltage sources controllable via two terminals in series connection. This standard has been prepared primarily for insulated gate bipolar transistors (IGBTs), but it also applies as a guide when other types of turn-off semiconductor devices are used. It does not apply to converter valves of line-commutated converters in HVDC systems. In addition, power losses in HVDC station equipment other than converter valves are excluded from the scope of this standard.
