Abstract

This paper presents a novel approach based on eigenvalue and eigenvalue sensitivity analyses to predict dynamic performances of parallel operated self-excited induction generators (SEIGs) supplying an induction motor load. Numerous numerical methods based on steady-state equivalent-circuit models have been proposed to find the performances of a SEIG connected to static loads. In this paper, determination of minimum capacitance required for starting the induction motor is analyzed. Experimental results obtained from laboratory 1.1 kW induction machines confirm the feasibility and effectiveness of the proposed method
