摘要：
The presence of friction and clearance in a steam turbine governing system can cause a limiting ring oscillation of the system. The variation of the limiting ring frequency and amplitude may serve as the characteristics of fault diagnosis. The frequency spectrum features of the limiting ring in various links will change, depending on the damping characteristics of signal transfer in the system. In view of this, by using the method of frequency spectrum analysis, the authors have attained a locating diagnosis of the friction and clearance, based on the ratio of high-order amplitude spectrum and basic wave amplitude of measurable signals. The feasibility of the above-mentioned method has been verified by a simulation test.
