Zusammenfassung:To reduce communication delay of data even if the situation of a communication path of the data changes, and perform a stable system operation.SOLUTION: A system monitoring device of the present invention includes: a reception unit that receives data transmitted from an external terminal provided in a power system via one of a plurality of communication paths and including transmission time at the terminal; a calculation unit that calculates difference between the transmission time included in the data and reception time of the data; and a transmission unit that transmits, to the terminal, a command indicating a change of a communication path used when the terminal transmits the data depending on the calculated difference.SELECTED DRAWING: Figure 1 【課題】 データの通信経路の状況が変化しても、データの通信遅延を軽減し、安定した系統運用を行う。【解決手段】 本発明の系統監視装置は、電力系統に設けられた外部の端末から複数の通信経路のうちの一つを介して送信され且つ当該端末での送信時刻を含むデータを受信する受信部と、データに含まれる送信時刻とデータの受信時刻との差を算出する演算部と、算出された差に応じて、端末からデータを送信する際に使用する通信経路を変更する旨の指令を端末に送信する送信部と、を備える。【選択図】 図1
