<P>PROBLEM TO BE SOLVED: To provide a contraction model creation method for distribution system which can contract a distribution system model, in condition that it keeps a certain accuracy in voltage analysis, and a contraction model creation system using this method. <P>SOLUTION: The contraction model creation method for a distribution system which creates a contraction model by contracting a distribution system model composed of a node and a branch divided by this node comprises a system condition setting process S20 which computes the voltage drop of a node by performing circuit computation, based on the distribution system model, a simple contraction process S40 which creates the contraction model by contracting the distribution system model, and a voltage control contraction process S50. <P>COPYRIGHT: (C)2008,JPO&INPIT |
