Monitoring Mass Concrete at Hydro Station
Switzerland: Imagine the energy carried by the water rushing 1833
meters downward to the three massive turbines at Bieudron power plant.
A ring pipe at each turbine directs the water into five jet nozzles where
it exits at a velocity of 690 km/h and hits each of the turbine buckets
35 times per second with a force of 57t per jet.
The complete system was brought on line in May, 1998, doubling the capacity
of the Grande Dixence power scheme. The Bieudron power house sets a record
for the maximum net head (1844m) and the size of the turbines (three 423
MW Pelton turbines, each powering a 465 MVA generators. The total excavation
volume was 7 million cubic meters for the galleries and the underground
