城市电网大型变电站环境噪声调查及治理建议

Environmental Noise Survey and Management Suggestions for Large-Scale Substation of Urban Power Grid

近年来城市变电站噪声问题日益突出,不可避免地会对附近环境和居民生活产生影响。分析了110、220、500kV变电站的站界噪声特点、常用降噪声措施等,为降噪软件设计、降噪工艺文件编写、降噪器件研制等提供参考。对一个220kV变电站和一个500kV变电站进行了站内噪声测试和分析,并提出了治理建议。

In recent years, the noise problem of urban substations becomes more and more serious, which will inevitably affect the nearby environment and residents＇ life. This paper analyzes the characteristics of boundary noise and the commonly used noise reduction measures in 110 kV, 220 kV and 500 kV substations, providing references for software design, processing document compilation, and device development of noise reduction. In-station noise testing and analysis were carried out and management suggestions were proposed for a 220 kV and 500 kV substation.
