SYSTEM MANAGEMENT SYSTEM, SYSTEM MANAGEMENT DEVICE, AND SYSTEM MANAGEMENT METHOD

PROBLEM TO BE SOLVED: To reduce effort required for setting a switch.SOLUTION: A system management system (2) comprises: a plurality of switches (SW) that are provided to a distribution system, and in which contact points are switched into a conduction from an insulation at a time when a throwing standby time defined depending on a preset time is passed from the reception of a power supply of a preset tidal-current direction; and a system management device (3) that sets the tidal-current direction and the time. The system management device comprises: a matrix generation part (31) that generates a matrix in which an element binary indicating the presence/absence of the switch is arranged in an order of the plurality of switches; and a time calculation part (32) that integrates the element selected from the matrix in accordance with the setting target switch and calculates the time.SELECTED DRAWING: Figure 2 【課題】開閉器の設定に要する労力を低減する。【解決手段】系統管理システム（２）は、配電系統に設けられ、予め設定された潮流方向の電力供給を受けてから、予め設定された時限により定まる投入待機時間が経過した時点で接点間が絶縁から導通へ切替わる、複数の開閉器（ＳＷ）と、潮流方向および時限を設定する系統管理装置（３）と、を備え、系統管理装置は、開閉器の有無を二値的に表した要素が配電系統における複数の開閉器の並び順で配列された行列を生成する行列生成部（３１）と、設定対象の開閉器に応じて行列から選択される要素を積算して時限を算出する時限算出部（３２）と、を備える。【選択図】図２
