Abstract :
A self-commutated ac/dc converter composed of
controlled turn-off devices to be applied to future system interconnection
is described. The advantages of a control system for
this type of converter are:
(1) Commutation does riot fail when the system voltage is
decreased or distorted by a power system fault.
(2) It needs no equipment for reactive power supply, such as
static capacitors or synchronous rotating condensers, when
used in a low short-circuit capacity power system.
(3) It can independently control active power through dc lines
and reactive power from each terminal.
The proposed back-to-back (BTB) control system using the
voltage margin method was verified with a power system
simulator, and the results demonstrated the excellent features of
the high-performance self-commutated converter.
