<p><P>PROBLEM TO BE SOLVED: To provide a device, method, and program for determining a system configuration with minimized transmission loss wherein transmission loss smaller than with a branch exchange method and the configuration of a distribution system with this transmission loss can be determined in a practical calculation time. <P>SOLUTION: A "closed" switch selecting means 12 selects a combination of n (n≥2) unselected "open" switches to be brought to a "closed" state so that mesh systems becomes one in the present system configuration. The state of the switches is changed to the "closed" state. The power flow of the mesh system generated by changing the state to the "closed" state is computed by a load-flow computing means 13. A "open" switch selecting means 14 sequentially selects "closed" switches where the value of current passed through them in the power flow of the mesh system calculated by the load-flow computing means 13 as switches to be brought to an "open" state. The state of the switches is changed to the "open" state. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
