    摘 要:針對電廠旋轉設備的運行狀態(tài)異常檢測問題,提出一種基于參數(shù)自適應DBSCAN算法的旋轉設備健康狀態(tài)在線評估算法。該算法中為降低人工設定鄰域半徑和密度閾值對密度聚類結果的影響,選用輪廓系數(shù)作為聚類結果有效性評價指標,基于粒子群算法(PSO)確定合理的參數(shù)值。采用參數(shù)自適應DBSCAN算法定期對正常運行時的歷史數(shù)據(jù)進行離線聚類分析,基于此聚類結果分析實時采集的數(shù)據(jù),在線評估旋轉設備的健康指數(shù)。對某電廠旋轉設備的運行數(shù)據(jù)進行仿真分析,結果表明所提方法能夠有效檢測設備異常運行狀態(tài),為設備的安全可靠運行提供保障。

    Abstract: In this paper, aiming at the detection of abnormal operation status of rotating equipment in power plants, this paper proposes an online health status assessment algorithm for rotating equipment based on parameter adaptive DBSCAN algorithm. In this algorithm, in order to reduce the influence of artificially set neighborhood radius (Eps) and density threshold (MinPts) on the results of density clustering, the contour coefficient is selected as Validity evaluation index of clustering results, determine reasonable parameter values based on particle swarm optimization (PSO). The parameter adaptive DBSCAN algorithm is used to periodically perform offline clustering analysis on historical data during normal operation. Based on this clustering result, the real-time collected data is analyzed, and the health index of the rotating equipment is evaluated online. After a simulation analysis of the operating data of a rotating equipment in a power plant, the results show that the proposed method can effectively detect the abnormal operating state of the equipment and provide a guarantee for the safe and reliable operation of the equipment.
    Key words: rotation equipment; health index; parameter adaptive DBSCAN algorithm; particle swarm optimization algorithm; online evaluation
