Fundamentals of Turbine/Generator Speed Control: A Graphical Approach for Islanding Applications

To promote a better understanding of industrial turbine/generator speed control, the fundamentals of droop and isochronous turbine/generator control are discussed via graphical examples for typical industrial islanding applications with bus-connected generators. A mathematical analysis of several examples illustrates the validity of a practical graphical approximation approach. By comprehending these fundamental concepts, industrial application engineers can more thoroughly investigate advanced governor control topics, such as isochronous load sharing with communication lines between governors, manual operator control of multiple generators, and load sharing via automatic power-management systems.
