Abstract :
In this paper, the simulation models of hydraulic turbine regulating system were developed in a MATLAB/Simulink-based software environment. These nonlinear characteristics of hydraulic turbine and the no-elastic water hammer effect of pressure water supply conduit were considered in the modeling. Some simulation tests have been performed, such as step speed disturbance test on no-load operation and step load disturbance test on isolated operation, which will cause small hydraulic transients in turbine hydraulic system. The digital simulation results manifest the accuracy and effectiveness of the MATLAB/Simulink-based hydropower plants hydraulic transients simulation system
