A hybrid hydropower power plant is a conventional Hydro-Power Plant (HPP) augmented with Battery Energy Storage System (BESS) to decrease the wear of sensitive mechanical components and improve reliability regulation performance plant. central task controlling HPP determining how total setpoint split between BESS hydraulic turbine (power splitting). This paper describes Model Predictive Control...

When designing a hydropower plant with long pressure penstock, special attention must be paid to the conditions in especially during emergency flow shutdown. In this paper, main principles of calculation static rise pipeline rapid shutdown are presented. The results obtained by analytical methods (calculation direct and indirect water hammer) numerical (mathematical modelling Matlab software en...

Mathematical and simulation models enable hydroelectric power unit dynamic behavior analysis using computers. In this paper, nonlinear mathematical of all elements in hydroelectrical plant are detailed described. Basic water supply tunnel, surge tank, penstock, turbine synchronous generator. If we want more credible simulations calculation results, have to use differential equations. Using thes...

One-dimensional stability analysis of a hydraulic system composed of a penstock, a runner, and a draft tube was carried out to determine the cause of the full load draft tube surge. It is assumed that the cavity volume at the runner exit is a function of the pressure at the vortex core evaluated from the instantaneous local pressure at the runner exit and an additional pressure decrease due to ...

The paper presents an approach to calculate the static pressure rise upstream of a valve in penstock hydropower plant (HPP), i.e. turbine, during emergency closure flow. calculated value is applied for design appropriate time HPP and sizing various parts (structural mechanical). basic theoretical background problem, calculation relations, range validity used relations are explained then procedu...
