<P>PROBLEM TO BE SOLVED: To provide a method for easily determining an output capacity of a generator on the basis of a short-circuit current irrespective of distribution states of distributed power supplies. <P>SOLUTION: The distributed power supplies are connected to a power cable at equal intervals so as to be along the cable. A power distribution factor is defined as a primary factor that indicates a node on a transverse axis and the output capacity of the distributed power supply at the node on a longitudinal axis. The unit reactance of the distributed power supply 2 with the own output capacity as a reference is equal in all the distributed power supplies. The unit reactance is converted into impedance in each of the power distributed power supplies 2 on the basis of the output capacity of each distributed power supply 2 that is defined by the power distribution factor, and admittance viewed from a prescribed point is calculated. Then, the short-circuit current that flows on the calculated admittance is calculated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
