Application aspects of generator and excitation system for process plants

This paper has been prepared to provide a better understanding of the subject matter and to serve as a guide for those involved in engineering, maintenance and operation of turbogenerators in a process plant. The paper covers all aspects of a turbogenerator and the system considerations that are required to achieve a reliable power system and minimize power outages during system disturbances. These include the following: (1) generator parameters; (2) excitation system; (3) neutral grounding; (4) protection; (5) synchronizing; (6) integration into the power system; (7) utility interface; and (8) islanding. Additional reference is provided for further investigation and clarification into the subject matter.
