ZAFRA, Carlos Alfonso; CASTILLO, Luis Hernando  e  RICO, Santiago Andrés. TECHNICAL PRE-FEASIBILITY IN THE WIND ENERGY GENERATION FOR CONVENTIONAL WATER PURIFICATION PLANTS: A COLOMBIAN REGIONAL CASE. rev.udcaactual.divulg.cient. [online]. 2013, vol.16, n.1, pp.223-233. ISSN 0123-4226.

A methodology to analyze the technical pre-feasibility of the use of wind energy for electricity supply in water purification plants (WPP), through the statistical treatment of weather records, the calculation of the energy supply and the sizing of the wind turbine is presented. Additionally, a nomogram for calculation of the above variables from the records of six WPP of the Sabana de Bogotá (Colombia): Principal, El Sosiego, Sibaté, Pablo VI, El Dorado and Yomasa is exhibited. The last two WPP were taken as main study cases. The results showed for the WPP El Dorado and Yomasa from its maximum flow (337.2 y 12.1L/s) and energy consumption (37,322 and 3,571kWh) that the weather conditions present at the heights of design (50 and 10m) offer a specific wind power of 245.3 and 67.6W/m², respectively. On the other hand, the existence of a linear relationship between the flow treated and the energy consumed by the six WPP in study (R² = 0.99) was noted Finally, the application of wind design nomogram to WPP El Dorado and Yomasa presented an average error of 0.54% and 1.25% in the calculation of the energy consumed and wind power, respectively.
