Summary:According to the present invention, a defect diagnosing method of a rotating machine comprises the following steps of: determining a defect level based on data obtained by diagnosing a state of a rotating machine, wherein the data for diagnosing the state of the rotating machine includes at least one of a feature vector related to a vibration signal of the rotating machine, a frequency associated with a defect of the rotating machine, or a total vibration value of the rotating machine; applying a weight to the defect level based on at least one of information related to a defect in state history data of the rotating machine or whether an alarm related to operation information of the rotating machine is generated; and determining a defect severity degree of the rotating machine based on the defect level to which the weight is applied. 본 개시에 따른 회전기계의 결함 진단 방법은 회전기계의 상태를 진단한 데이터에 기반하여 결함 레벨을 결정하되, 상기 회전기계의 상태를 진단한 데이터는, 상기 회전기계의 진동신호와 관련된 특징벡터, 상기 회전기계의 결함과 연계된 주파수 또는 상기 회전기계의 전체 진동 값 중 적어도 하나를 포함하는 단계 및 상기 회전기계의 상태 이력 데이터 상의 결함과 관련된 정보 또는 상기 회전기계의 운전 정보와 관련된 알람의 발생 여부 중 적어도 하나에 기반하여, 상기 결함 레벨에 가중치를 적용하는 단계 및 상기 가중치가 적용된 결함 레벨에 기반하여 상기 회전기계의 결함 심각도를 결정하는 단계를 포함할 수 있다.
