Title:
POWER DISTRIBUTION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2016220388
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power distribution control device capable of efficiently collecting regenerative energy even in the case where a plurality of motors are defined as controlled objects.SOLUTION: The power distribution control device comprises: an operation bus bar 2 for distributing power to motors 12 while receiving power supply from an external commercial power source 10 during normal operation of the motors 12 as controlled objects; a power storage bus bar 4 for delivering the regenerative power that is supplied from the motors 12, to an external power storage facility 11 during regeneration utilizing the regenerative energy of the motors 12; operation breakers 3 that are individually connected between the operation bus bar 2 and the motors 12; power storage breakers 5 that are individually connected between the power storage bus bar 4 and the motors 12; and a control part 6 which controls the operation breakers 3 and the power storage breakers 5. During the regeneration, the power storage breaker 5 is turned on while being linked with a breaking operation of the operation breaker 3 for the motor 12 that receives a stop command, such that regenerative power is sent out to the power storage facility 11 via the power storage bus bar 4.SELECTED DRAWING: Figure 1
