POWER SUPPLY METHOD OF POWER DISTRIBUTION AUTOMATION SYSTEM

PROBLEM TO BE SOLVED: To solve the problem that when the elements of a power distribution system are not structured in a tree based on a graph theory, it is impossible to calculate an optimum solution for power supply to the entire tree when power fails. SOLUTION: A supply point distribution means is provided at a supply calculation processing section. When power fails, a supply point from an outside section to a power failure section is divided into a plurality of virtual supply points for configuring a power network, to be recovered in a tree. After that, the power supply operation is executed by a division processing means. In the distribution of the supply point by the supply point distribution means, the supply point is divided into k virtual supply points for connecting each side when a supply point (u) is connected to k demand points, and the amount of supply at the virtual supply point agrees with that at the supply point (u).
