Abstract
PURPOSE: To provide the subject device wherein at the time of normal running of the DC transmission system a current set value at the usual driving is imparted to the system and at the time of trouble a current set value on which the DC becomes within the interrupting capacity is imparted thereto, thereby facilitating cutting off of the inverter in trouble.
CONSTITUTION: Taking notice of a fact that even the conventional DC interrupter can interrupt a DC if it is suitable, the set current for each of the inverters is lowered so that the current becomes an interruptable current, thereby to suppress to interrupt the current flowing into the troubled inverter. That is, in a multiterminal DC transmission system in which a plurality of AC-DC inverters are connected to the DC line through respective DC interrupters, a set value Idf at the trouble is provided, in addition to a set value Idp of a constant-current control circuit ACR and a current margin necessary for power inverting time, and if any inverter is in trouble, the unit receives the signal which has detected the trouble, thereby to change over to the set value Idf
