Abstract :
In this paper different finite-element (FE) techniques are effectively combined to obtain the standstill frequency response of synchronous machines. As a result, actual risky and high cost tests can be largely avoided. Lagrange multipliers are employed to joint two FE meshes of different densities at the air gap region. Explicit consideration of the external circuitry connected to the machine is performed through a simultaneous and effective solving of the field and circuit equations
