摘要

Many providers for small hydropower plants equipment have tried to standardize the components and even the entire equipment. So called 'compact turbines' were launched on the market, ensuring the pre-designed solution of the modular components, but usually with lower efficiency then turbines specially designed for a certain site. For civil works it is possible to standardize some components, such as the powerhouse, the surge tank or the headrace, but not the intake and the weir. Part of the hydropower plants can be standardized, but not the entire project, because there are a lot of variables that influence the design. Among these, the dimension, materials and design of the canal and the penstock are given by the hydrology, topography and the geology of the project's area. This paper presents an attempt at standardization by using different heads and different installed flows. The case study is made on the Lukosi River from Tanzania, because there is a good hydrological database on power and energy calculation. For the powerhouse, pressure tower and intake dimensioning, the assumptions and materials considered cover all challenges that could appear in the geological and topographical structure of the project's area (worst case, most expensive). The study has highlighted African climatologic and hydrological conditions and the adapting of current technology to these conditions.
