A starting from zero DC voltage build-up procedure for a magnet-free synchronous reluctance generator in reduced speed operation

Abstract

This paper proposes a parametrized procedure for the voltage build-up of a synchronous reluctance generator connected to a three-phase, two-level controlled rectifier. The magnet-free synchronous reluctance generator is considered in severe conditions where it is neither connected to the grid nor to an electrical energy storage system. Moreover, a reduced speed operation is assumed. The procedure is based on an analysis of the torque generated by the interaction between the residual magnetism and the currents of the generator that maximize the reluctant torque. The choice of the procedure's parameters that improve the chances of successful voltage build-up are discussed. Experimental verifications are carried out in order to illustrate the analysis.
