<P>PROBLEM TO BE SOLVED: To provide a node group classifier for power system which enables the user to perform the planning and the maintenance of power system operation, by classifying the power system into groups, in units of nodes strong in correlation, based on the impedance information between nodes, from the viewpoint of voltage maintenability. <P>SOLUTION: This node group classifier is equipped with a means 11 which computes the equivalent impedance between each node and the next, by using system data, a means 12 which makes a simple model 17 by deleting connection where equivalent impedance is not less than some threshold in an equivalent model 16 having connected all nodes with one another; a means 13 which classifies each node into a monitoring site which becomes the monitoring object in voltage reactive power control; a control equipment installation site where a transformer; a phase modifier and a synchronous phase modifier are installed, and other groups, a means 14 which makes an internode matrix 19A that shows the existence of connection, referring to the simple model 17; and a means 15A which computes the logical sum with the group of monitoring sites at the nodes belonging to other groups, referring to the internode matrix. <P>COPYRIGHT: (C)2007,JPO&INPIT |
