Method of reducing a hydraulic diagram
CALTUR proposes a calculation method for reducing the hydraulic diagram of the power plant, in order to bring it back to the study of a simple circuit comprising only one turbine, supplied by a water supply through a single conduit of length Leq and section Seq.
The HydroStab calculator uses a simplified model, deduced from a preliminary study of the hydraulic circuit.
This study determines the equivalent length and section Leq and Seq, allowing a complex hydraulic circuit to be reduced to a simple form using known methods, as shown in the figure above.
Non-exhaustive reminder of some formulas used in this study:
Of course, it is also necessary to take into account the section reductions in the circuit. For example, for a section of variable section:
