摘　　要：以某110kV户外变电站为例,分析厂界噪声超标原因,结合变电站实际情况,提出了噪声超标治理方案,利用SoundPLAN仿真软件分析了方案实施前、后变电站及周围环境不同高度水平面的声压级分布,并给出了噪声超标治理的具体措施,结果显示,变电站噪声治理效果显著,4侧厂界昼、夜噪声的最大削减量均达7dB(A),治理后的变电站4侧厂界噪声均满足噪声排放标准相应级别的要求。Taking a 110 kV outdoor substation as an cxample,the causes of factory boundary noise exceeding standard arc analyzed.Combined with the actual situation of substation,control scheme of the noise exceeding standard is proposed.SoundPLAN simulation software is used to analyze the sound pressure level distribution of substation and surrounding environment at different heights before and after the implementation of the scheme,and the specific measures for noise exceeding standard control arc given.The results show that the effect of substation noise control is remarkable,and the maximum reduction of day and night noise in the four-side plant boundary reaches 7 dB(A).The noise in the four-side plant boundary of the treated substation meets the requirements of the corresponding level of noise emission standards.
