Ten-year experience in the operation of the Plyavinyas hydroelectric station
- 11 Downloads
A complex of national economic problems was solved successfully during construction at the Plyavinyas station.
The hydraulic structures and power equipment generally are operating reliably. The seepage characteristics in the majority of structures have not reached the design values. The stresses in the reinforcement of most structural elements have not reached the design values. Settlements and displacements of the powerhouse have decreased considerably, but have not yet stabilized.
Problems of the repair of flowing vertical drain wells were not solved when designing the station, which creates operational difficulties.
At sharp-peaking hydroelectric stations periodic piezometric observations are insufficient for evaluating the seepage state in the zone of influence of the lower pool level fluctuations.
It is necessary to increase the reliability and wear resistance of the electrical and hydraulic equipment intended for sharp-peaking stations.
