dc.description Quantitative analysis of re-routing a high-head, low-flow, run-of-the-river, under-100 kW hydroelectric power plant penstock and comparison with the original route for purposes of head loss estimation and available hydraulic power prediction en_US
dc.description.abstract Part of the infrastructure of a disused mill in Dee, Oregon is being converted into a hydroelectric power station. A turbine and generator combination must be selected to match the flow and pressure at the bottom of the penstock. One old penstock route is being abandoned and replaced with a new route. Inaccurate flow versus pressure measurements exist for the old penstock route. In order to estimate the available hydraulic power which can be expected from the new penstock route, both routes were mapped with special attention paid to elevation changes. Total head was found to be 473 feet over a distance of roughly 3.8 miles. The effects of fittings and pipe dimensions, materials and ages on pressure dissipation were accounted for via minor loss correlations and both Darcy-Weisbach and Hazen-Williams equations. For each penstock route, total head loss was calculated at various flow rates from which total hydraulic power could be estimated. The head loss calculated in the old route was compared with the existing measurements. At the permitted water right flow rate of 2.5 cubic feet per second, hydraulic power is predicted to be 93 kilo Watts using the new route and a Pelton turbine is recommended. While the original measurements corroborate this finding, corrections made to the measurements suggest that 80 kilo Watts is a more reasonable power estimate. It is recommended that new flow versus pressure measurements be taken before a final turbine selection is made. en_US
