Spectrum Analysis of Noise in Low Head Francis Turbine

Abstract:

Hydroelectric generating sets of a hydropower station have emerged a serious problem of abnormal noise in the Chinese southwest. To analyse the low-frequency characteristic of noise, a noise test was done in the power station site, and the noise of different working conditions was recorded. After the spectral analysis, the average dominant frequency and average loudness of noise were got, it is the basis of subsequent analysis and research. This article has some reference value in the noise monitoring and diagnosis.
