Hydro Power-Clarification Request On Certain Doubts

I do 3D modeling for a company that makes formwork for constructing dams, tunnels, bridges, etc. We are currently working on 2 in Canada and one here in the states. I can't directly answer your question, but we are building the outflow from the turbines and that is 25+ feet in diameter on the largest, with 3 making up one station. The outflow then divides into 3 channels per turbine. I will look in the contract drawings and see if i can find estimated wattage, but they are construction drawings, not technical ones.

siw40364,

Thank you for the response & I look forward to see your further inputs.

Even a small hydro plant as the Pykara one in the Nilgiris had four turbines way back in 1954 (I visited this as a high school student). The shift engineer told me that it was to minimise load stress to 25% /machine in case of breakdown/maintenance. This may have to be taken into consideration in your assessment.

However, having more turbines has other investment implications.

Thank you Sir for the inputs.

If you take Kadamparai, pumped storage power plant as an example,you have four branchings 100 M.W each for the total of 400M.W capacity.

My case is related to ultra power plants[ base as well as peak load options] normally ranging from a minimum plant capacity levels 1000 M.Watts.

Break down safety is one criteria as you have mentioned rightly.

You should go for 3 to 5 equal sized turbo generators depending on % peak load.
