Abstract

PURPOSE: To make a self-exciting inverter usable through the exact detection of power receiving failure by providing a backward power detector which detects a backward power based on a regenerative power flowing at the 2nd power feed system, and a short time mock load sent to the 2nd power feed system at this detection time.
CONSTITUTION: A regenerative power (route R2) circulating into a power receiving system 50 and a transformer system 51 at the time of power receiving failure is taken notice of, and a backward power relay 21 which has connected with respectively electric current and voltage elements from the seconds of the converter 25 and transformer 26 of a high pressure power distribution system 53, is connected. And the backward power relay 21 makes the direction (route P2) to be sent to the high distribution system 53 and a load 20 from a power receiving source 50 a forward power, and moreover, makes the direction (route R2) from the high distribution system 53 to the power receiving source 50 a backward power, that is, an action direction power, and each power is set. As a result, the backward power relay 21 can detect electric power heading in the power receiving source system 50 and transformer system 51 directions from a power regeneration device system 54, which is a characteristic at the power receiving failure time. Also, the breaker 22 of a mock load 23 is thrown in at the operation time of the backward power relay 21.
