Summary:To provide an information processing device capable of increasing objectivity in estimation of an event occurrence time.SOLUTION: An information processing device estimates an event occurrence time when an event causing a change in a frequency of power has occurred, based on, among pieces of frequency information indicating the frequency of power at each time point at a predetermined point in an AC interconnected grid including one or more generators, frequency information in a target period including an estimated period in which the event is estimated to have occurred.SELECTED DRAWING: Figure 7 【課題】イベント発生時刻の推定についての客観性を向上させることができる情報処理装置を提供する。【解決手段】情報処理装置は、１つ以上の発電機を含む交流連系系統内の予め決められた地点における時刻毎の電力の周波数を示す周波数情報のうち、前記周波数を変化させるイベントが生じたと推定される推定期間を含む対象期間における前記周波数情報に基づいて、前記イベントが生じたイベント発生時刻を推定する。【選択図】図７
