Full-scale investigations of ejection in combined hydroelectric plants with pressure spillways
Conclusions 1. The utilization of ejection in combined plants, with spillways discharging under pressure, may have a positive effect on energy, by increasing, under conditions of average floods, the power available from the units by a sizable percentage, and the annual output of the plants by 0.3–0.7%. 2. The analysis of the pressures prevailing under the jet of the issuing spillway flows, according to the formulas proposed by Professor S. M. Slisskii [3], gave generally good agreement with the results of the measurements, in those cases in which the test was performed under conditions close to those of a two-dimensional problem (XXII CPSU Congress plant, and Uch-Kurganskaya plant). With the spillway flows being utilized in a single section, the effect of ejection decreases substantially as a result of lateral action of the discharge of adjacent sections with spillways closed (Dubossarskaya plant). 3. The uniform distribution of the spillway flows among the ejectors of all sections with operating units assures for the plant, on the whole, the highest total effect of ejection on energy.
