Universal mathematical model of hydraulic and steam prime movers

The results of development and research of an universal (adaptable) mathematical model of hydraulic and steam prime movers of generators of electric power systems are presented in the paper. The created model allows modeling the continuous spectrum of processes in any particular type of these prime movers with the high completeness and adequacy, which is important for an adequate simulation of normal, emergency and post-emergency regimes and processes of electric power systems. The adequacy of the developed model is verified by experimental studies with the Hybrid Real-Time Power System Simulator (HRTSim).
