辽宁地区部分220kV变电站噪声污染研究分析

Study on Noise Pollution of 220kV Substations in Liaoning Province

环境噪声已成为社会普遍关注的焦点问题,环境噪声影响的纠纷也越来越多。为了了解220kV变电站站界噪声分布特性,本文对辽宁地区所属61座典型220kV变电站排放噪声进行测试分析,明确了站界的噪声污染水平。同时,在实测的基础上重点对有敏感点以及环境影响较大的变电站频谱特性和衰减规律进行分析研究。共检测610个测点,结果显示变电站站界噪声值均在允许范围内;变电站主要噪声污染频段在中低频区域,做防护措施时需要重点关注;同时,植被区对噪声的衰减具有一定积极作用。

Environmental noise has become a common concern of the society, and there are more and more disputes over environmental noise. In order to understand the noise distribution characteristics of the 220 kV substation, in this paper, the emission noise of 61 typical 220 kV substations in Liaoning province is tested and analyzed,and the level of the noise pollution is clarified. At the same time, the analysis and research on the spectral characteristics and attenuation rules of substations with sensitive points and environmental impacts are emphasized on the basis of actual measurement. The results of 610 measurement points show that all data from the measurement were allowed by the standard; The main noise pollution zone in the substations is in the middle and low frequency areas, which need pay more attention in precaution;Meanwhile, the vegetation area has a positive effect on the attenuation of the noise.
