PURPOSE:To realize high performance power supply to a load by comparing the sum of the power of normally operating generators, at the time of the fault of the generator, with the sum of the power of generators immediately before the fault, and by interrupting a load according to an interrupting priority level on condition that the sum of the power of the generator other than faulty machines is lower than the sum of the power of the generator immediately before the fault. CONSTITUTION:A load interruption controlling signal of an OR gate 13, a storage signal of a storage section 15, a generator rated power adding signal of a rated power collecting section 17, and a load power signal of an operation load rated power computing section 18 are inputted to an interruption load capacity processing section 19, which then outputs an interruption capacity signal corresponding to a load interrupting quantity corresponding to the electric energy of a faulty generator. Operation signals of loads 2a-2n are inputted to an interrupting priority level discriminating section 20, which then judges the priority of load to be interrupted and outputs an interrupting priority signal. From an interruption load selecting section 21, the output of a break command signal is directed to the load to be interrupted. As a result, an overload can be prevented from being generated. |
