摘　　要：文章深入探讨了引起水轮发电机组振动的机理 ,在分析水力、机械、电气三个因素对机组系统振动影响的基础上 ,应用d’Alembert原理的直接平衡法和赖柴陀螺原理建立了考虑上述三个因素的机组系统振动的动力学控制方程。首次对上述三个因素进行了离散和解耦 ,清楚地揭示了上述三个因素对机组振动的独立贡献及相应的耦合关系。The paper makes a thorough study on the hydro generator unit vibration mechanism. Based on the analysis of the hydraulic, mechanic and electric factors that have effects on the power generating unit system vibration, the paper has established a dynamic control equation by applying both the d'Alembert principle's direct balanced method and the gyro principle. The paper makes for the first time the discrete and decoupling analysis of the three factors, which clearly reveals the independent contributions of the above-mentioned factors and their corresponding coupling relations. The power generating unit shutdown and maintenance cases in the past proved that the above conclusions are correct.
