Resumen:
This paper presents an analysis of sound pressure levels through
theoretical modeling and experimental validation in a 1 kW small wind
turbine. The models used in the theoretical analysis are BPM (Brooks,
Pope, and Marcolini) and BM (Brooks and Marcolini), where wind turbine
blades are divided in sections, and each section has its own
contribution with respect to the total emitted sound pressure level. The
noise propagation study and its experimental validation were
accomplished within the requirements of the standard IEC 61400-11 Ed.3
and the standard NOM-081-SEMARNAT-1994. The comparative study of
theoretical and experimental results showed that the BPM and BM methods
have a maximum error of 5.5% corresponding to the rated wind speed of
10 m/s. However, at low wind speeds, the theoretical models fit well to
experimental data, for example, in the range from 5 to 8 m/s. The
experimental data showed that the rotor's aerodynamic noise is more
evident at low wind speed, because under these conditions, environmental
noise is much less than wind turbine noise. Finally, to prevent possible
negative effects on people's health, there is a recommended minimum and
suitable distance between small wind turbine installations and
buildings.
