Summary: | To provide an abnormality diagnostic technique which early detects abnormality of a rotating machine by using plant operation data so as to conduct causal diagnosis.SOLUTION: An abnormality diagnostic method of a rotating machine, which diagnoses abnormality of the rotating machine, includes: an operation data acquisition step of acquiring operation data of the rotating machine; a change rate calculation step of calculating a change rate of the operation data; and an abnormality determination step of determining the abnormality when the change rate exceeds or underruns an abnormality determination value J.SELECTED DRAWING: Figure 1
【課題】 本発明の目的は、プラント運転データを用いて、回転機械の異常を早期に検知し、原因診断を行う異常診断手法を提供することにある。【解決手段】 上記課題を解決するために、回転機械の異常を診断する異常診断方法であって、前記回転機械の運転データを取得する運転データ取得ステップと、前記運転データの変化率を算出する変化率算出ステップと、前記変化率が異常判定値Jを上回ったとき、または、下回ったときに、異常と判定する異常判定ステップと、を有する回転機械の異常診断方法とした。【選択図】 図1 |
