HYDRO TURBINE GENERATING SETFOR VERY LOW HEAD

Presentation





Why a new type of hydroelectric turbine?

• No Manufacturer in the world offers a Turbine fitted for heads of less than 2 m.•The most profitable sites are already built in developed countries. • The remaining potential is located below 2 m gross head.• Same comments are valid worldwide

Presentation




Civil Work cost is 5 times higher under 1,5m head than under 3 m head

•Eels are individually examined before and after the tests.•Eels are divided in two batches according to their size (above and bellow 1 m length)• After the passage eels are classified in 2 categories :

– Living eels are in perfect state and 100 % survive 48 h after the tests

– Dead eels are neatly cut in two.

Eels are « pinched » at runner blade end

Possible improvement of the

VLH

•The survival rate can be improved, with a small modification of the runner discharge ring shape• Death rate could be divided by 3 allowing a survival rate estimated above 97 - 98% •New tests with the new spherical profile early 2010
