<P>PROBLEM TO BE SOLVED: To provide a method for recovery from an accident in a distribution line system, wherein a distribution line will not be overloaded during recovery from an accident. <P>SOLUTION: The method for recovery from an accident is for a distribution line system, in which any one of multiple sections of a distribution line partitioned by multiple section switches can be linked with a distributed power supply. Each load on multiple sections of a distribution line and the allocable capacity of the distribution line, with respect to a substation for power distribution, are determined in advance. After a distributed power supply is paralleled off and multiple section switches are opened at an accident in the distribution line, each of the multiple section switches is instructed to turn on, in a predetermined order of turn-on by a power distribution control device that monitors and controls the section switches and the distributed power supply. At this time, the total of the loads in the sections of the distribution line in which one section switch is turned on and to which power is supplied from the substation for power distribution is compared with the allowable capacity of the distribution line. When the total of the loads does not exceed the allowable capacity, the relevant section switch is instructed to be turned on. When the total of the loads exceeds the allowable capacity, the relevant section switch will not be instruct to be turned on. <P>COPYRIGHT: (C)2007,JPO&INPIT |
