Abstract
The estimation of armature reaction is of great importance in the design and operation of synchronous machines. This paper proposes a new method to reduce quadrature armature reaction in salient-pole synchronous generators. The proposed method is to reduce the quadrature axis synchronous reactance of a salient-pole synchronous generator by novel flux barrier to the rotor poles. Finite element analysis by Maxwell software was used to evaluate the nonlinearity of the synchronous reactances and to obtain the result that the quadrature axis synchronous reactance decreases when the flux barrier is introduced into the rotor pole of a salient-pole synchronous generator. As part of the study, a new flux barrier was introduced and experimented on the rotor pole of a 50 kW, 4-pole salient-pole synchronous generator without damper winding used for diesel generator.
