This paper presents the voltage build-up process and the terminal voltage control of a stand-alone self-excited induction generator (SEIG) using direct vector control (DVC) technique under variable speeds and different types of load. Here, the three-phase SEIG is excited by a pulse-width modulated voltage source inverter (PWM-VSI) connected to a single-capacitor on the DC side with a start-up battery...
The performance of three-phase Self-Excited Induction Generator (SEIG) with Static Synchronous Series Compensator (SSSC) is investigated to feed various static loads. The employed SSSC is a three-phase, Insulated Gate Bipolar Transistor (IGBT) based, PWM operated, Current-Control Voltage source converter (CC-VSC). The reference current to generate the gating signals is obtained by employing only one...
Induction generators operating in a stand-alone mode are increasingly being used in isolated areas. Such a generator has very poor voltage regulation. This paper proposes a simple thyristor-switched capacitor (TSC) type voltage regulator for a stand-alone induction generator to maintain voltage within the upper and lower acceptable limits. The capacitor size in each TSC branch is selected very carefully...
This paper presents the analysis of dynamic and steady state performance of a self excited induction generator (SEIG) with digitally controlled electronic load controller (ELC) feeding single phase loads. The excitation capacitors, electronic load controller, 1-phase load in conjunction with the d-q model of the 3-phase induction machine taking into account the saturation effect are used to predict...
