Abstract

This paper presents steady-state performances of an isolated three-phase, self-excited induction generator (SEIG) supplying an induction motor (IM) load. An approach based on synchronously rotating reference frame d-q axis inductionmachine model is employed to derive steady-state equations of the studied machines. The branch of equilibrium point is calculated by a predictor-corrector type continuation method. Eigenvalue analyses are employed to determine the critical operating conditions and examine the stability of each equilibrium point. The required minimum excitation capacitance of the SEIG, the maximum torque of the induction motor load, the maximum operating efficiency of SEIG, etc., of the studied system can easily be investigated. The transient responses of voltage collapse due to heavy load torque are also performed. Experimental results obtained from a laboratory 1.1 kW induction machine driven by a DC motor and a 300 W induction motor with a magnetic powder brake as its shaft load are also performed to confirm the feasibility of the proposed method.
