Abstract

A fixed-pitch wind turbine power performance improvement technology was studied in order to solve the problem that the actual output of fixed-pitch wind turbines is lower than the rated output in the plateau areas. Considering with the environmental characteristics in plateau areas, one blade-adding technology was proposed, by adding a blade lengthening section to increase the rotor swept area to improve power performance. The software BLADED was used to simulate different length of the blades, economic benefit and safety assessment were conduct and the optimal length of the blade lengthening section was 650mm. The results indicated that a rate of 8.64% increase of power generation was gained after one year performance, the static investment period is about 3 years and the generating gain is about 1.68 million RMB in life period. The blade-adding technology can provide reference of how to improve the output of the fixed-pitch wind turbine.
