100 Flexibility in Pumped-Storage Systems: Hydraulic short circuit as additional operating mode – Simulation and validation(PPT)

摘要

1. Frequency control increasingly required or possibility to operate existing pumped storage power plants more economically (not necessarily to the pleasure of the operating team!). 2. The measurements performed prove the reliability and accuracy of the numerical simulations (both pressures, as well as loads and frequencies). 3. Through a precise analysis of the overall system, new, more efficient operating modes, such as hydraulic short-circuits, can also be implemented in existing systems.
