Abstract:
In order to control growing noise pollution in urban indoor substations efficiently, calculation of the sound field in chambers and residential areas is done. With the software ANSYS 11.0 SP1, Nanjing Daxinggong 220kV substation and Fucheng 220kV substation are taken as examples to simulate and analyze the sound field in the main transformer chamber as well as the reactor chamber. Meanwhile, LMS SYSNOISE is utilized to simulate and calculate the sound field of residential areas, 45 m away from the main transformer chamber. According to simulation results, the sound pressure level in the main transformer chamber reaches a maximum of 90.6dB at the frequency of 63Hz, while the sound pressure level in the reactor chamber reaches a maximum of 93.0dB at 125Hz. The A-weighted equivalent continuous sound pressure level in residential areas is 47.51dB, exceeding our national emission standard at night. The calculation results are in good agreement with the experimental data. The model can be modified to simulate and predict the sound field in substations of the same kind so as to put forward an optimum proposal for noise treatment based on techniques of noise insulation, noise elimination, noise absorption as well as vibration isolation.
