Self-excitation systems for synchronous generator with bipolar and unipolar PWM DC-DC converter

摘要

Models of Synchronous Generators with PWM DC-DC converter and Self-Excitation Systems have been designed. Calculations have shown that the unipolar PWM DC-DC converter in some modes shortly excludes from the voltage regulation process. The bipolar PWM converter effectively affects the generator and consequently enhances the system operation speed. The bipolar PWM converter uses the energy recovery in exciter as a short-circuit protection. The unipolar DC-DC converter uses explosive fuse and dumping resistor as a short-circuit protection.
