In this paper, the dynamic response of a hydro power plant for providing secondary regulation reserve is studied in detail. Special emphasis is given to the elastic water column effects both in the penstock and the tailrace tunnel. For this purpose, a nonlinear model based on the analogy between mass and momentum conservation equations of a water conduit and those of wave propagation in transmission lines is used. The influence of the plant configuration and design parameters on the fulfilment of the Spanish Electrical System Operator requirements is analysed.

W artykule analizowano odpowiedź dynamiczną elektrowni wodnej użytej jako wtórna rezerwa. Uwzględniono efekt elastycznej kolumny wodnej zarówno w rurociągu jak i w odpływie. W tym celu zaproponowano nieliniowy model bazujący na analogii równaniami zachowania masy i momentu a falową propagacją linii transmisyjnej.
