EXCITATION CONTROL SYSTEM FOR MARINE DIESEL BRUSHLESS DOUBLY FED SHAFT GENERATOR AND CONTROL METHOD THEREOF

摘要

This invention publishes a type of excitation control system structure and control method for ship diesel engine brushless double feed shaft-driven generator. The excitation control structure of ship brushless double feed shaft-driven generator includes contactor, step-up transformer, rectification feed unit, DC compensation unit, inverter unit, control panel, excitation controller, AB phase voltage, CA phase voltage sensor, BC phase voltage sensor; based on the control method for control system structure, initial excitation, constant-voltage control, constant frequency control, undervoltae control and overvoltage protection for ship brushless double feed shaft-driven generator can be realized.
