Software and hardware simulation tools of automatic load-frequency control system

This paper proposes the modeling automatic load-frequency control system implemented in the Hybrid real time simulator of electric power system (HRTSim). HRTSim developed for different simulation tasks does not impose any restrictions on the application of mathematical models and allows reproducing spectrum of normal, emergency and post-emergency processes in the electric power systems. The results of experimental studies of steam turbine momentary and sustained fast-valving simulation for transient and steady state stability in the power system confirm the adequacy of simulation tools.
