Abstract

This work proposes a new model for dynamic behavior of hydro-electric turbines on the basis of inlet mechanical power with different loads together with reactions of wicket gates and governor during load rejection. Then, practical experiments are investigated, and their results are compared with simulated results developed in SIMULINK. The results show that proposed modeling satisfies practical behavior of real systems.

Highlights

The studied model is on the basis of power while former studies introduced models investigating torque.
In this model, the simultaneous effect of both governor and brakes has been investigated.
The presented model can be developed considering surge tanks and performance of pressure in sections of turbine for further studies.
