Numeričke simulacije hidrauličkih tranzijenata u crpnoj hidroelektrani Fužine (Numerical simulations of hydraulic transients in PHPP Fužine)

Hydraulic transients in pumping hydroelectric power plant (PHPP) Fužine were simulated with 1D unsteady pipe flow model. High accuracy of the model was accomplished with the use of nonconservative formulation of unsteady pipe flow model incorporating unsteady friction model and second order flux limited numerical scheme. Simulation results show very good agreement between the computed and measured piezometric heads, both in amplitude and frequency of the oscillation.
