Abstract:Diplomska naloga »Obratovalne karakteristike modela vetrne turbine v cevi in v prostem toku« je zasnovana na ideji, da meritve karakteristik modelov vetrnih turbin v cevi ne dajejo verodostojnih rezultatov, ker hitrostni in tlačni profil v cevi vplivata na karakteristiko. Meritve so opravljene pod kontroliranimi pogoji v laboratoriju. Z ventilatorjem se je ustvaril veter, ki se mu je z meritvami določila hitrost ter izračunala moč. Električna moč se je določila prek meritev toka in napetosti ter vrtljajev turbine. Mehanska moč se je določila z napetostmi na merilnih trakovih ter z izkustvenimi enačbami. Rezultati so pokazali, da se modeli v prostem toku obnašajo zelo drugače kot v cevi.

Title:Operating characteristics of wind turbine model in pipe and free flow
Abstract:The diploma thesis titled “Comparison of Operating Characteristics of Wind Turbine Models in the Tube and in Free Flow” is based on the idea that wind turbine model characteristics measurements in the tube do not yield reliable results, because the speed and pressure profile in the tube may impact its characteristics. Measurements were made in controlled conditions in a laboratory setting. Using a ventilator, the wind was generated, its speed measured and its power calculated. Electric power was determined by measuring the electric current, voltage, and the number of revolutions of the turbine. Mechanical power was determined by measuring voltage and using experiential equations. Results show that the models behave considerably different in free flows than they do in tubes.
Keywords:wind turbines, operating characteristics, efficiency, wind energy, measurements in pipe and in free flow, renewable energy
