<P>PROBLEM TO BE SOLVED: To utilize the capacity of a distributed power supply in the consumer of a low voltage system effectively when a high voltage system is faulty. <P>SOLUTION: A low voltage system 3 which is in system interconnection with distributed power supplies 1A and 1B and supplies power to a plurality of consumers 2A, 2B and 2C including at least one consumer 2A having a distributed power supply 1A, is isolated from its upper system, i.e. a high voltage system 4, when it is faulty, and the voltage of the low voltage system 3 is maintained by one distributed power supply which is in system interconnection with the low voltage system 3. Excess and deficiency of power are calculated for every consumer 2A, 2B, 2C, and surplus power is supplied from a consumer having excess power to a consumer for which power is insufficient. <P>COPYRIGHT: (C)2008,JPO&INPIT |
