Real-time simulation of hydraulic turbine governing system based on ARM

Simulation of hydraulic turbine governing system plays an important role in teaching, testing and experimental study. This paper presents the overall structure of the ARM-based real-time simulation system on the basis of a comprehensive analysis of the characteristics of hydroelectric process. For the different object to build different fineness of model, this paper uses multi-scale modeling approach and rational scheduling mechanism to realize optimal operation of simulation, as well as designing the real-time enhanced program on a LINUX system. By comparison with the off-line system simulation of SIMULINK, the results show that the system is fully capable to meet the requirement of hydraulic turbine governing system on real-time, reflecting the advantages of real-time continuous simulation.
