Characteristics of the calculation of surge tanks of hydroelectric stations

Zakachurin, S. V.

Conclusions The presently used form of taking into account losses in a transition and velocity head correspond only to the initial conditions of the transient. It is recommended to determine the losses on the basis of experimental data with consideration of the actual ratio of discharges in the diversion conduit and surge tank.The calculations show that the refined consideration of hydraulic losses in the transition leads to a greater range of fluctuations of the level. Refinement is especially important for small lengths of the pressure conduits and small values of the additional resistance coefficient of the surge tank.
