This work focuses on the analysis of the power generation feasibility of both a pump as turbine (PAT) and an experimental propeller turbine; when applied to water supply systems. This is done through an analysis of the electrical generation aspects of the PAT’s induction motor and of a permanent magnet DC motor; which was connected to the propeller turbine. The collected data allows for parameter optimization; adequate generator choice and computational modeling. These tests constitute a good sample of the range of applicability of small scale turbines as valid solutions for micro-hydro. It is also possible to consider multiple scenarios; such as rescaling/resizing; for larger turbines and systems; and the use of power electronics for further efficiency enhancing.
