Optimal Sizing of Low Head Hydropower Plant- A Case Study of Hydropower Project at Head of UCC (Lower) at Bambanwala
Pakistan is facing serious shortfall of electricity for few decades. Small hydropower projects can alleviate the worsening situation. The sizing of a low head hydropower plant plays a vital role in establishing the feasibility of the project. The plant needs to be optimized for energy produced, efficiencies of the plant components, number of units and its financial/economic parameters. This pap...
متن کاملThe exploitation of low-head hydropower by pressure interchange with air, using siphons
The paper describes and analyses a hydropower system based on siphons in which the pressure of low-head water is converted into air pressure. The analysis suggests that, with careful design of the ow passages to minimize losses, air-pumping ef ciencies of 70 per cent or more should be achievable; the overall ef ciency of the hydropower system should be better than 60 per cent. Although such...
متن کاملWater level control system for a low-head run-of-river variable speed small hydropower plant
This paper presents part of the work carried out within the framework of a research project entitled Application of variable speed and intelligent control technologies to hydropower generation. Specifically, it is focused on the activities performed in order to achieve one of the main objectives of the project: the design of a water level control system for a low-head run-of-river variable spee...

متن کاملEffects of changes in flow velocity on the phytobenthic biofilm below a small scale low head hydropower scheme
This study presents a spatial analysis of physical and biotic river conditions below a low head hydro scheme in the River Goyt, UK. The overall aim was to assess whether changes in localized hydrological features, introduced by low head hydro, affect phytobenthic biomass. Single point and profile measurements of flow velocity and velocity vectors, elevation, depth and biofilm biomass were mappe...
