Abstract

This paper presents a comparative study of long-shunt and short-shunt configurations on dynamic performance of an isolated self-excited induction generator (SEIG) feeding an induction motor (IM) load. The studied IM is suddenly connected to the output terminals of the studied configurations of the SEIG. Both simulated results and experimental results based on laboratory 1.1 kW induction machines are clearly compared to examine the effects of both connections on voltage variation of the studied SEIG. The analyzed results show that the long-shunt configuration may lead to unwanted oscillations while the short-shunt connection provides better voltage variation. The eigenvalue technique is also employed to examine the possible voltage collapse and unstable conditions in the studied SEIG-IM system
