POWER DISTRIBUTION FACILITY MANAGEMENT DEVICE, POWER DISTRIBUTION FACILITY MANAGEMENT METHOD AND POWER DISTRIBUTION FACILITY MANAGEMENT PROGRAM

To provide a power distribution facility management device, a power distribution facility management method and a power distribution facility management program for improving the safety and reliability of a power distribution facility.SOLUTION: A weather calculation part 12 performs weather calculation for calculating weather information according to time passage at each point of a calculation region on the basis of weather information at a specific time point. A sea salt scattering calculation part 13 calculates a sea salt scattering amount according to the time passage of each point on the basis of the weather information calculated by the weather calculation part 12. A sea salt adhesion amount calculation part 15 calculates the amount of sea salt adhering to a power distribution facility at each point on the basis of the weather information and the sea salt scattering amount according to the time passage at each point. An update facility determination part 16 specifies a threshold determination reference position and a threshold determination reference time on the basis of the increasing rate of the number of damage occurrences due to sea salt rapid contamination that occurs in the calculation region in the past, and with the amount of sea salt adhering to the power distribution facility at the specified threshold determination reference position and threshold determination reference time as a threshold, specifies a power distribution facility that exceeds the threshold as a power distribution facility having a high possibility that a sea salt damage occurs.SELECTED DRAWING: Figure 1 【課題】配電設備の安全性及び信頼性を向上させる、配電設備管理装置、配電設備管理方法及び配電設備管理プログラムを提供する。【解決手段】気象計算部１２は、特定時点での気象情報を基に、計算領域の各地点での時間経過に応じた気象情報を求める気象計算を行う。海塩飛散計算部１３は、気象計算部１２により求められた気象情報を基に、各地点での時間経過に応じた海塩飛散量を算出する。海塩付着量計算部１５は、各地点での時間経過に応じた気象情報及び海塩飛散量を基に、各地点での配電設備への海塩付着量を算出する。更新設備決定部１６は、計算領域において過去に発生した海塩急速汚損による被害発生数の増加率を基に閾値決定基準位置及び閾値決定基準時刻を特定し、特定した閾値決定基準位置及び閾値決定基準時刻における配電設備への海塩付着量を閾値とし、閾値を超えた配電設備を海塩被害の発生する可能性が高い配電設備として特定する。【選択図】図１
