摘要：Reactor noise is one of the main noise sources in substations. It has obvious low-frequency noise characteristics and long transmission distance, which has a great impact on the sensitive targets of the acoustical environment at the substation boundary and outside the substation. In order to solve the problem of the boundary noise exceed the emission limits caused by 10 kV dry shunt reactor in a 220kV substation, noise reduction measures using noise barrier are proposed, and the effect of noise reduction is simulated and analyzed based on SoundPLAN software. The test results show that the noise reduction measures adopted can ensure that the noise at substation boundary meets the emission limit requirements.
