Wavelet-Galerkin method for computations of transient behaviors of electrical machines

Sixth International Conference on Advances in Power System Control, Operation and Management - Proceedings, Hong Kong, 11-14 November 2003A wavelet-Galerkin method is proposed for the computer simulation of transient behaviors of electrical machines. To consider the interaction with the external components of the frond end of the machine such as power electronic devices, the proposed wavelet-Galerkin method is combined with a state space model to develop an integrated simulation approach. An iterative procedure is also proposed to solve simultaneously the two system equations. Numerical results of computer simulations on the transient behavior of a prototype PWM inverter-fed motor drive are used to validate the feasibility of the proposed method for transient behavior simulation of general electromagnetic devices.Department of Electrical EngineeringRefereed conference pape
