Abstract :
The transient performance of 3-phase 4-wire self-excited induction generator (SEIG) feeding various types of linear and non-linear loads is analyzed in detail. The reactive power of SEIG and the load are being controlled by a 3-phase 4-wire configuration of static compensator (STATCOM). The STATCOM is an insulated gate bipolar transistor (IGBT) based, pulse width modulation (PWM) operated, four-leg voltage source inverter (VSI) with suitable self supporting DC link capacitor. The study is carried out for static R-L load, a motor load and non-linear rectifier fed load. Various problems of 3-phase 4-wire isolated generating system such as voltage regulation, unbalancing of loads, harmonics currents and neutral current are compensated by the STATCOM.
