<P>PROBLEM TO BE SOLVED: To efficiently narrow down candidates satisfying operational constraints by using a strict solution method such as ROBDD in a power distribution network using a three-division and three-linkage power distribution method. <P>SOLUTION: This device for optimizing a distribution system configuration is composed of a distribution system information storage device 11, a node model information storage device 12 which stores information for dividing a distribution system displayed by graphics into a plurality of closed partial feeders less than three linkages by a build-up portion, a partial feeder preparation device 13 which retrieves the total number of partial feeder configurations which satisfy radial configuration constraints in the respective partial feeders, a three-division restraint and a voltage drop constraint in the partial feeders, a loss calculation device 14 for calculating losses in the partial feeders, a precision calculation device 15 for calculating all candidates which satisfy line capacity constraints at the root of the feeder by the strict solution method, and a power distribution loss minimum configuration specifying device 16 which specifies one candidate where the power distribution loss becomes the minimum among the candidates which satisfy voltage drop constraints as a power distribution loss minimum configuration. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
