This paper presents a comparative study of long-shunt and short-shunt configurations on the steady-state characteristics of a three-phase self-excited parametric generator (SEPG) under different power-factor loads. The stator windings and the rotor windings of the SEPG are connected in series with different phase sequence and the slip of this machine is always equal to 2. The three-phase induction machine model is employed to derive the steady-state equations of the SEPG feeding to various power-factor loads. The load voltage versus load admittance under different power factors are examined and compared. Experimental results obtained from a laboratory 1.1 kW induction machine driven by a DC motor are also performed to confirm the feasibility and effectiveness of the analyzed results. It can be concluded from the experimental and simulated results that the long-shunt connection can provide better voltage regulation of a SEPG than the short-shunt connection under various power-factor loads.
