The main plant of Shangyoujiang Hydropower Station is located in the overflow dam section of the fasting gravity dam, similar to the underground type or closed river bed type power station. Equipped with 4 sets of 15000 kw vertical axis turbine generator set. This dam-type plant has poor ventilation, humidity and noise of the three major shortcomings, especially the noise ambassador operating personnel suffer, now the source of noise, noise reduction measures and effects are described below. (A) the source of noise and its characteristics After the determination, the main sources of noise within the plant has the following aspects:
