Conditions of converting a hydroelectric station with horizontal bulb units to a hydroelectric station-pumped-storage station regime

Conclusions

• 1. On-site investigations of the equipment of the Kiev HES confirmed the possibility in principle of realizing the suggestion on converting the horizontal bulb units to a HES-PSS regime in the presence of a cascade of reservoirs with impounded pools.

• 2. The most acceptable and reliable method of starting horizontal units with a submerged waterway is frequency starting from adjacent machines with power consumption with the runner blades turned not more than 0.15PP _n .

• 3. Constant operation of standard horizontal bulb units in pump regimes is difficult owing to the high level of hydrodynamic loads on their operating components.

• 4. With consideration of the acute need for mobile regulating facilities, it is necessary to recommend the accelerated reconstruction of operating bulb units for operation in the reverse regime at heads of 7–12 m and their experimental operation.

• 5. Pump regimes at hydrostations have a sanitizing effect on biological processes in reservoir.
