Meyer, Raymond A. DeCarlo, Steve Pekarek, Chris Doktorcik School of Electrical and Computer Engineering, Purdue University, West Lafayette, IN 47907-1288, USA Abstract This paper develops and validates a power flow behavioral model of a gas tur- bine engine with a gas generator and free power turbine. “Simple” mathematical expressions to describe the engine’s power flow are derived from an understand- ing of basic thermodynamic and mechanical interactions taking place within the engine. The engine behavioral model presented is suitable for developing a supervisory level controller of an electrical power system that contains th
