Modeling of Mechanical Shaft-field-circuit-network Coupled Time-step Finite Element Method for Dynamic Analysis of Large Machine and Power Network
摘要
Abstract
In order to accurately study the impact on large machine and power network of system disturbance, the mechanical shaft-field-circuit-network coupled time-step finite element model was set up. The comprehensive coupling of the multi-mass spring mechanical shaft system-2D transient electromagnetic field-circuit-power network was realized. In the model, the distortion of electromagnetic field, magnetic saturation, eddy current and parameters of power transmission system were taken into account in dynamic process, and dynamic behavior of mechanical shaft was considered in detail as well including the mechanical torque transmitted by every mass, damping torque and the speed variation of different mass. To validate the proposed model, the simulation and experimental results of faulty synchronization at 120º, performed on the dynamic simulation experimental system in State Key Laboratory of Hydropower Equipment, was compared and analyzed. The results show that the model is correct and effective.关键词
