A Comparison of Results Obtained with Two Different Methods for Calculation of Horizontal Axis Wind Turbine Performance, Part 4

摘要

The turbine and flow field are described with finite element techniques. For the case of a wind turbine operating in steady uniform flow, performance and load characteristics were calculated and compared with the results from the standard computer program, WINRO, based on a combination of blade element and momentum theory. The calculations were made for a reference test case at different wind speeds. The reference unit is a 9 m radius two bladed 65 kW turbine. The results are in excellent agreement except for low wind speeds probably because three dimensional effects are more important for low wind speeds than for high.
