Research on the Application of Serrated Structure to the Noise Reduction of Wind Turbine Blades
摘要
Abstract
Based on the noise test standard for the wind turbine generator system of IEC61400-11, noise test system is built by NI hardware and LabView software. The field tests on acoustic emission values of the blades of a 3.0 MW wind turbine generator system before and after adding the serrated noise reduction structure are conducted respectively. By comparing the noise values at the measurement points in the 4 m/s-8 m/s wind speed range with the 1/3 octave spectrum data, the effect of the serrated structure applied to the blades of the large wind turbine generator system is studied. The result shows that installing serrated structures on the blades can significantly reduce the noise when the wind turbine is operating in 5 m/s-6 m/s wind speed range, and also has obvious noise reduction effect for low frequency noise in high wind speed range.关键词
