Wicket Gate Closure Control Law to Improve the Transient of a Water Turbine

Abstract:

The increase in speed and system hydraulic pressure may cause major accidents during the transient of load rejection, especially in high-water head hydropower plants. The current study presents a wicket gate step-by-step closure control law, where two guide vanes will be closed asynchronously to reduce the increase in pressure and improve the transient quality of a waterturbine. Compared with the calculated data in the routine closure law, the control law obviously improved the dynamic qualities of the transient in load rejection and decreased the rising hydraulic pressure from the water diversion system of the plant. The proposed control law can replace the role of a surge tank under certain conditions.
