Fast start of hydraulic turbines is mandatory for a successful integration of renewable sources of energy. Successful handling of this issue needs to operate close to the boundary of the admissible domain while fully exploiting the knowledge of the system dynamics. This paper introduces a simplified model of hydraulic turbines including the hydraulic nonlinear hill-chart and a first order model of...
Fast response of hydraulic turbines is a key condition for the integration of renewable sources of energy. In this paper, a new start-up strategy is proposed for hydraulic turbines prone to “S” instability. This method is based on a complete nonlinear model of the turbine together with the upstream water pipe. More precisely, the control strategy is based on a gain scheduling approach that is computed...
