Modelling of hydraulic turbine for dynamic studies and performance analysis

Abstract: Classical ideal lossless representation of the hydraulic turbine has been used widely in the past for governor stability studies. This model is suitable for small perturbations around the initial operating condition, and approximates to the practical turbine characteristics at low frequencies only. For satisfactory fast response and stable operation of governor studies, this classical model may not be adequate, rather a more accurate modelling of the turbine-penstock characteristics is desired to capture and d… Show more

“…But, because of analytic expressions of transfer coefficients can not be derived in long time, calculation of transfer coefficients dependent on hydro turbine model performance curves which is the steady performance of hydro turbine, which means dynamic process is studied with steady performances for hydro turbine. The dynamic model with high order of hydro turbine is built in [10], but its transfer coefficients are constant. Transfer coefficients defined in [11] can reflect the change in transient, but they are not explicit expressions.…”

“…The governing of GVs plays a significant role in the stable and smooth operation of the turbine unit [5]. The smooth operation of the GV control system is required to protect the turbine from instabilities like transient frequency deviation, ultra-low frequency oscillation in the power system, water hammer effect in the penstock, vortex formation, and flow separation [6,7].…”
