UPDATE PLAN CREATION ASSISTANCE DEVICE, UPDATE PLAN CREATION ASSISTANCE SYSTEM, AND UPDATE PLAN CREATION ASSISTANCE METHOD

摘要

Provided are an update plan creation assistance device, an update plan creation assistance system, and an update plan creation assistance method which consider a redundant configuration of equipment and can appropriately evaluate the degree of impact on a power system from a breakdown of the equipment. The update plan creation assistance device is provided with: a breakdown information storage unit that stores information indicating the ease of occurrence of a breakdown of equipment; an operation status acquisition unit that acquires information indicating the operation status of the equipment; and a redundant information storage unit that stores information indicating a redundant configuration of the equipment. A breakdown risk calculation unit calculates a breakdown occurrence probability from information indicating the ease of occurrence of a breakdown of the equipment, and calculates, on the basis of information indicating the operation status of the equipment and information indicating the redundant configuration of the equipment, a breakdown risk that indicates the magnitude of the degree of impact on a power system from a breakdown of the equipment. An update plan creation unit creates an update plan for the equipment on the basis of the calculated breakdown risk.
