| description | This paper presents an analytical method for the calculation of currents and power losses in the damper winding of large salient-pole synchronous machines at various steady-state operational conditions. The algorithm is based on a damper winding network containing all damper bars of a repetitive section of the machine. The self and mutual inductances as well as the induced voltages are computed taking into account the air-gap permeance function. The presented algorithm is used to compute currents in the damper winding at open-and short-circuit test conditions. The obtained analytical results are compared with the results of transient finite element studies. |
