ABSTRACT:
Control units are provided associative with forward and inverse converters in a multiterminal DC power transmission system, respectively. The control units set different constant voltages in the converters. Further, the minimum value of the constant voltage set values in the forward converters is set at a value larger than the maximum value of the constant voltage set values in the inverse converters.
