摘要：
Qualitative analysis and quantitative analysis are combined to carry on hydraulic variable pitch system fault diagnosis of wind turbine. Fault tree model of hydraulic system is established by the analysis of hydraulic system fault symptoms set. Petri net model of hydraulic system fault can be obtained by fault tree using the matrix operations of Petri net to achieve the conversion from qualitative to quantitative which can make up the shortcoming of fault tree model inclining to qualitative analysis when the basic event is difficult to determine its occurrence probability. The validity of the model is verified by simulation example.
