Turbine types suit specific ranges of head; flow rate and shaft speed and are categorised by specific speed. In the pico range; under 5kW; the requirements are often different to that of larger scale turbines and qualitative requirements become more influential. Pico hydro turbines can be applied beyond these conventional application domains; for example at reduced heads; by using non-traditional components such as low speed generators. This paper describes a method to select which turbine architecture is most appropriate for a low-head pico hydro specification using quantitative and qualitative analyses of 13 turbine system architectures found in literature. Quantitative and qualitative selection criteria are determined from the particular requirements of the end user. The individual scores from this analysis are weighted based on perceived relative importance of each of the criteria against the original specification and selects a turbine variant based on the total weighted score. This methodology is applied to an example of a remote site; low head and variable flow specification and used to select a propeller turbine variant or single-jet Turgo turbine for this specification.
