Study on AC-Excited Generator Stator Flux Orientation Vector Control

The AC-excited generator stator flux orientation control principle was expounded, the relationship between active power, reactive power and rotor excitation current was derived for generators. The fundamental structure of AC-excited generator current loop and power loop of dual closed-loop control model was established, the determination of magnetic field amplitude of stator location was discussed. Study on AC-excited generator using dual loop PID regulator excitation control simulation was conducted. It was shown by simulation that stator flux orientation control principle can de-couple active power and reactive power control with high speed.
