Abstract
PURPOSE: To form to enable to operate the revolving machine continuously, without stoppage of the machine, by making breaker at sound bus bar side automatically, when the bus bar is no voltage caused by trouble or the like of one side distribution equipment.
CONSTITUTION: When any trouble is occured in distribution equipment 2 side and electric failure is occured in double bus system, underpower relay 21 is operated, breaker for receivig 7 and breakers 31, 32 for distribution are tripped, and at the same time, voltage is impressed on voltage. phase relays 43, 44 by action of the relay 21. From this, residual voltage and sound voltage at distribution equipment 3 side are compared by power generating operation of the revolving machines 5, 6, making instruction is given to switching breakers 27, 28 by the relays 43, 44 in sound voltage and phase difference of the revolving machine, and these breakers are made. From this reason, sound voltage is impressed in each revolving machine, and the machine continues continuous operation without stoppage. Characteristics of each revolving machine can be seen without receiving influence of mutual interference of each revolving machine by doing such operation independently in each distribution line.
