The HYDROTUR-HydroSim project provides a set of new tools useful for the
dynamic numerical simulation of hydraulic power units
driven by FRANCIS, KAPLAN, or PELTON (1 to 6 needles) turbines. It includes
detailed and robust models of speed control for rotating machines.
These programs are characterized by fully non-linear modeling across the entire
operating range of the machines.
They can thus be used to simulate all start-up sequences, connection to the
electrical grid in an interconnected or isolated network,
partial or 100% load shedding, normal shutdown of the unit, on electrical or
mechanical faults of the turbine.
HydroSim takes into account models with machine hills when available.
The project allows simulations of wave or mass water hammer depending on the
case study, and calculates the approximate pressure losses in the hydraulic
conduits.
HydroSim integrates the simulation of the elements of a hydraulic turbine, in
the form of XCOS diagrams :
- The turbine
- The hydraulic network supplying the turbine (water supply)
- The electrical network
- The speed governor and its system copying the servomotor(s)
HydroSim complies with international standards IEC 60308 and 61362 in the
calculated results.
HYDROTUR is therefore particularly well suited for technicians and engineers
involved in design, specific projects, or commissioning,
in order to obtain reliable preliminary calculations regarding the stability of
control loops.
