Abstract

PURPOSE:To contrive direct current breakers to be done without increasing the capacities, by locking the interrupting action of the direct current breakers, when an accident is generated on a transmission line in a state that the only one transmission line among a plurality of transmission lines is operated. CONSTITUTION:The branch points of direct current transmission lines 31, 32 are provided with direct current breakers DCCB1-DCCB4. States during each operation or stopping of the direct current transmission lines 31, 32 are kept stored, and when only one circuit among the direct current transmission lines 31, 32 is worked because of an accident or forced stopping or the like, then the direct current breakers are contrived not to be worked even if the accident is generated on the transmission lines.
