Application of Noise Control Technology in Noise Control of Power Grid Substations
The main noise sources of power grid substation are analyzed emphatically,and the application of three noise control technologies,namely acoustic wave guidance,active noise control and electromagnetic shielding,in substation is discussed.Aiming at the low frequency noise and high frequency noise in substation,the corresponding control measures are put forward,and the noise reduction effect is verified by practical cases.The results show that the comprehensive application of various noise control technologies can significantly reduce the noise level of substations,improve the working environment and reduce the impact on surrounding residents,which provides effective technical reference and guidance for noise control of substations.
