Analysis of Aerospace Electric Power System Dynamics with a Digital Computer

A mathematical representation of a typical aerospace electric generation system is developed for solution using a digital rather than analog computer. The system consists of a gas turbine driving an electric generator and hydraulic pump. The representation of the speed, voltage, and temperature control loops is detailed. Of importance is the development of a format necessary for digital solution, and of a representation for transient power flow between the exciter and generator field in a brushless generator.
