Modification of turbine runner blades at the chirkey hydroelectric station
Conclusions 1. Modification of the runner blades of mixed-flow turbines, as the experience of modifying the turbine runners at the Chirkey hydrostation shows, leads to an increase of the power parameters of the turbines — power and efficiency — which makes it possible to regrade the units to a higher capacity. 2. The positive effect from modifying the runner blades at the Chirkey hydrostation consists in a 10% increase of capacity of the hydrostation; in an increase of efficiency due to a shift of the operating characteristics by 0.5–4% toward larger powers (for loads of the unit of 50% of the nominal and higher); in an increase of efficiency due to an increase of its maximum values at the extremes of the operating characteristics by 0.5–3%. 3. The effect from increasing the efficiency increases with increase of the operating heads of the turbines.
