Dynamic behavior of a single-phase self-excited induction generator using a three-phase machine feeding single-phase dynamic load

摘要: Abstract This paper is motivated to analyze the transient behavior of a single-phase self-excited induction generator (SEIG) using three-phase machine due switching dynamic load like motors. The consists star connected excited with three-capacitors and motor (IM) load. developed models SEIG are based on stationary reference frame d–q axes theory incorporating effect cross-saturation in magnetic circuit equations excitation capacitors described by abc model. system suffers from heavy transients during becomes unstable. These problems may be resonance caused series inductive use damping resistors across one capacitor proposed damp out starting for stable operation. can started up successfully resistor. variation resistance increase after successful maintain constant terminal voltage has been presented. eigenvalue technique also employed examine conditions studied SEIG-IM system. simulated experimental results presented both unsuccessful motor. close agreement each other, which show effectiveness approach.
