Operating characteristics of heavy-duty gas turbines in utility service

Abstract

With the increasing utilization of gas turbines in industrial and cogeneration applications, they are taking on a greater role in base load service. Because of their inherent responsiveness, they also offer operating characteristics that can enhance their contribution to utility systems as a generator prime mover. This paper will describe these characteristics, particularly as they relate to the interaction of the gas turbine, the governor, and the temperature control system. Additional features, such as load control, variable inlet guide vanes, peaking operation and other unique characteristics are also discussed from this point of view.
