Abstract:The effects of structural parameter disturbances on the dynamic characteristics of an actual hydropower station powerhouse were analysed.The power flow analysis method considering complex disturbances and parameterrelated disturbances were focused.On the basis of single disturbance analysis,the stochastic perturbation method was expanded and integratedly used with the dual disturbances analysis,power flow analysis,Kronecker algebra and Hadamard product.The correctness and feasibility of the method were validated by an example of analyzing the vibration model of the hydropower station powerhouse.The results indicate that the method proposed can efficiently reduce the disturbance range and can accurately analyze the transfer paths of vertical vibration in hydropower stations.
