Prime-mover response and system dynamic performance

Prime-mover response characteristics are influenced by the dynamics of turbines, boilers, and hydraulic systems, as well as by such control devices as speed governors and boiler-turbine controls. Some of the common types of prime-mover systems considered are the conventional single and double reheat systems, once-through units, and hydraulic turbine units. The pertinent phenomena are discussed, as are the implications of prime-mover response in the light of normal and emergency load-change duty.
