Attenuation characteristics analysis based on a real pumped storage power station The attenuation characteristics of the high-frequency pressure vibration in the pumped storage power station are analyzed in this section.
Thus, the maximum attenuation rate is less than 0.00092 (corresponding to 1200 m/s) and normally equals around 0.00031 (corresponding to 1100 m/s).
Thus, the attenuation rate of the vibration could be directly derived from the wave speed. For example, the wave speed of the headrace tunnel in a pumped storage power station is usually set around 1100 m/s and normally will not exceed 1200 m/s in the hydraulic transient simulation [, , ].
The influence of material properties on the attenuation rate of high-frequency vibration is analyzed. High-frequency vibration is a common hydraulic phenomenon in pumped storage power station. In this study, a theoretical model for analyzing the high-frequency vibration in fluid-pipe-surrounding support coupling system is established.
Furthermore, the attenuation rate (negative direction) also increases with the increase of the spring constants because a better bounding condition could deliver more stress and vibration energy from the shell to the surrounding rock.
The characteristics of large-scale energy storage and flexibility enable the pumped storage power stations to possess the ability of peak regulation, frequency regulation, voltage support, and so on in the power grids [4, 5].
