A FIELD EXCITATION SYSTEM AND METHOD FOR A WOUND ROTOR SYNCHRONOUS GENERATOR

摘要

The present invention relates to a system and method for driving a winding-type rotor synchronous generator. The present invention, as a winding-type rotor synchronous generator drive system, controls the winding-type rotor synchronous generator, a converter for receiving the generated power, field winding power supply means for supplying power to the field winding of the rotor of the generator Contains; The field winding power supply means is connected to the converter, and receives power from the converter to supply power to the field winding, but a winding type rotor characterized in that the power received from the converter is electrically insulated and supplied to the field winding. A synchronous generator driving system is provided. According to the present invention, as a field winding power supply means for supplying power to a rotor field winding of a large-capacity winding-type rotor synchronous generator, avoiding the conventional method of using slip rings and brushes requiring continuous maintenance, and rotating transformers By adopting a method of supplying power to the field winding through a rotating rectifying part such as a rotor of a transformer, it is possible to provide a power generation system that is simple to maintain, semi-permanent and highly reliable.
