| Abstract |
Coupled simulation environment is presented,
where electrical machines are modeled by the finite element
method (FEM) with circuit equations and coupled to
converter models in a system simulator. The method is
based on weak coupling, providing possibility for multiple
time step levels in the system model. Examples concerning
the analysis of current and voltage harmonics, additional
losses and tooth forces, are presented for 2 MW cage
induction motor, 9 MW and 12.5 MW synchronous motors
and 1.5 MW permanent magnet synchronous motor
supplied by frequency converters. Also the future outlook of
coupled FEM-system simulation is discussed in terms of the
actual need for coupled models and the research interests on
the coupling method development. |
