Abstract
Since it is difficult to construct the accurate equipment model due to the complex operation condition of the heat-engine plant's primary air fan and the strong coupling property of its multi-state variable,the intelligent data mining method is applied to the warning and diagnosis of the air fan equipment. The typical operation characteristic of the air fan is analyzed to propose the primary air fan vibration state estimation and fault warning method based on least-square support vector machine(LS-SVM). In combination with the historical operation data of the first unit's 1# primary air fan in Shanxi Hequ Power Plant,the Matlab is used to verify and analyze the method. The study results indicate that the method has high estimation accuracy,can timely identify the abnormal vibration of the operating primary air fan,is suitable for the fault diagnosis of the heat-engine plant's auxiliary equipment,and has a certain engineering application value.关键词
