Recovery of compensation water at the Pouzin Dam
The compensation water at the le Pouzin dam on the Rhône, when initially discharged, represents energy which can be recuperated by an M.P.S. which the company put into service in 1991. The low variation of the head and the certainty of the compensation water provide production which is very reliable and stable. The original design of the siphonic water intake has enabled the investment costs to be limited by reducing the interference with existing works. The control over the compensation water has been greatly increased by the M.P.S. because the turbine is a guide vane type with fixed blades; previously the water was partially discharged by a crest gate on the dam. The frequent clogging of the screen on the water intake led to the installation of a horizontal screen rake, whose efficiency so far is not very convincing. Studies on improving this efficiency are still under way. After initial problems the siphon water intake solution is giving the anticipated results. It is a solution which is economically attractive and reliable from a technical point of view.
