Analiza wektorowych metod przekształtnikowego sterowania autonomicznym generatorem indukcyjnym

The paper presents the problems of vector converter control of isolated self-excited induction generator. The converter systems of three-phase isolated induction generator with excitation from a three-phase PWM inverter with a single capacitor on the DC side are presented. The use of a static PWM inverter for controlling of induction generator excitation gives a good transient response and a smooth variation of excitation current. The system of PWM excitation with PWM inverter placed in series with induction generator is presented. The vector control methods of self-excited induction generator are developed and discussed. The control schemes based on generator magnetic field orientation are presented. The direct and indirect control based on rotor flux orientation and control based on direct stator flux orientation are described. Some selected results of simulation of control performance are presented.
