摘　　要：针对水轮发电机组振动故障原因复杂、特征参数多的特点,将模糊层次分析法和灰关联相结合,并引入模糊合成运算,较好地解决了寻找样本中各故障原因困难的问题。实例分析结果表明,该方法可有效诊断出水轮发电机组振动故障的原因,具有一定的适用性。Focusing on the characteristics of complex fault cause and many eigen parameters of the vibration of hydro turbine generating unit, combined fuzzy analytic hierarchy process with grey relation analysis and integrated fuzzy com- pound arithmetic, the difficulty of finding fault cause in samples was solved. The practical example results show that the method can effectively diagnose the vibration fault cause of hydro-turbine generating unit and it has applicability.
