AGUIRRE, L. A.; FONSECA, A. R.; TORRES, L. A. B.  y  MARTINEZ, C. B.. Efficiency measurement with uncertainty estimates for a Pelton turbine generating unit. Lat. Am. appl. res. [online]. 2010, vol.40, n.1, pp.91-98. ISSN 0327-0793.

The estimation of efficiency for a hydraulic electricity generating plant requires the measuring of the inlet water flow. This measurement is rarely available in most small and medium-sized hydraulic power plants, and was not available at the plant investigated. This paper discusses the solution developed to measure the inlet flow and therefore the efficiency of the generating unit. Confidence bands were estimated for the measurand (efficiency) based on Monte-Carlo simulations. The tuned algorithm has been tested using independent data collected at the hydroelectric power plant and agrees quite well with a validation set of measurements.
