To provide an accident cause classification device that updates an accident classification model for classifying accident causes according to change of electric power system facilities and ambient environment of electric power system facilities.SOLUTION: An accident cause classification device according to an embodiment has a model storage part, a measurement information acquisition part, an accident information acquisition part, a cause information acquisition part, a result information acquisition part, an accident history information storage part, a tendency determination part, an object information storage part, an object accident information storage part, and an update model generation part. The measurement information acquisition part acquires measurement information representing a result of measurement. The accident information acquisition part acquires accident information representing whether an accident takes place. The cause information acquisition part inputs the measurement information acquired by the measurement information acquisition part in the timing of the acquisition of the accident information to the accident classification model to acquire cause information. The tendency determination part determines whether object facilities change in state based upon the measurement information. The update model generation part generates an after-update accident classification model to be used instead of the accident classification model, and stores it in the model storage part.SELECTED DRAWING: Figure 1 【課題】電力系統設備及び電力系統設備の周辺の環境が変化に応じて、事故原因を分類する事故分類モデルを更新する事故原因分類装置を提供する。【解決手段】実施形態の事故原因分類装置は、モデル記憶部と計測情報取得部と事故情報取得部と原因情報取得部と結果情報取得部と事故履歴情報記憶部と傾向判定部と対象情報記憶部と対象事故情報記憶部と更新モデル生成部とを持つ。計測情報取得部は、計測を行った結果を示す計測情報を取得する。事故情報取得部は、事故が発生しているか否かを示す事故情報を取得する。原因情報取得部は、事故情報が取得されたタイミングで計測情報取得部により取得された計測情報を事故分類モデルに入力し原因情報を取得する。傾向判定部は、計測情報に基づいて、対象設備の状態が変化しているかを判定する。更新モデル生成部は、事故分類モデルに代えて用いられる更新後事故分類モデルを生成しモデル記憶部に記憶させる。【選択図】図１
