Abstract:
The essay evaluates the modeling, control and analysis of a doubly-fed induction machine (DFIM) using a three
level three stage voltage source inverter known as voltage source converter (VSC). VSC is utilized to control the extent and
period of the rotor voltage in a proficient way and can consequently be used to control the dynamic and receptive force of the
doubly fed induction machine. The stator circuit of the DFIM may either be supplied by a variable recurrence VSC or
straightforwardly from the a.c. system. Both cases are exhibited and analyzed. Distinctive torque and rate control strategies
could be examined with the goal of wiping out the back electromotive power (EMF), which adversely affects the rotor current
often considered as a load disturbance. Similarly, the essay will expound on the system of space vector control of doubly fed
induction machine driving a permanent magnet synchronous generator that supplies a three stage a.c. load. The control
methodology composed here is attempting to accomplish the utmost reduction of harmonic distortion in the voltage and
current generated. The findings were analyzed in Simplorer 7 to demonstrate the adequacy of the proposed strategies for
velocity and voltage control of doubly fed induction machine utilizing VSC.
