Abstract

The inductance parameters of the main generator of a wound-rotor synchronous starter/generator changed significantly with the variation of field current and armature current, so traditional position estimation methods based on magnetic saliency are no longer applicable. In order to improve the accuracy of estimation, a novel initial rotor position estimation method of a wound-rotor synchronous starter/generator based on multi-stage-structure characteristics is proposed in this paper. Square wave voltage signals were imposed on the stator of the main generator, and the response current signals extracted on the stator of the main exciter were used to estimate position information. This method eliminates the dependency on the magnetic saliency. Experimental results verified the feasibility and effectiveness of this method.
