Stationary excitation system using spatial voltage vector method

摘要

The present invention relates to a stationary excitation system using a space voltage vector method, wherein the generator field power is controlled using a PWM boost converter and a PWM inverter, and the PWM boost converter includes a PWM boost converter control unit using a space voltage vector modulation method. The power factor control and the magnitude of the DC output voltage are controlled, and the inverter measures the generator output voltage and current, compares the generator voltage with a set value commanding the generator, and uses a signal compared with a triangular wave through proportional integration control. It is characterized in that it is configured to switch control of the PWM inverter. The present invention also provides a circuit for supplying excitation power to a field through an AC / DC converter, an AC / DC converter for converting a three-phase power source controlled by a resonant voltage vector modulation method into a DC power source, and the AC / DC converter. It is characterized in that the circuit for supplying the output voltage of the converter to the field through the boost converter is connected in parallel and duplicated.
