摘要

探究不同厂界地形对变电站内声屏障降噪效果的影响，可以为变电站内声屏障的布置提供依据，也可为新建变电站的选址提供参考。以江苏某500 kV变电站为例，使用AWA6228声级计对站内两台变压器以及高抗的噪声声功率进行测量，构建变压器多点等效源模型对变电站噪声分布进行预测，通过对比预测与实测数据验证了所构建模型的准确性。使用该模型探究不同地形条件下声屏障位置和高度对其隔声量的影响，通过研究惠更斯—菲涅尔的波动理论发现上坡地形时声屏障降噪效果最差，且坡度越陡声屏障对噪声的阻隔作用越弱；下坡地形时声屏障降噪效果最好，坡度越陡声屏障对噪声的阻隔作用越强。文中结论可为厂界地形优化和新建变电站选址提供参考。

Abstract

Exploring the influence of different plant boundary topographies on the noise reduction effect of sound barriers in substations can provide a basis for the layout of sound barriers within substations

as well as a refrence for site selection of newly built substations. A 500 kV substation in Jiangsu Province is taken as an example

type AWA6228 sound level meter is used to measure the sound power levels of two transformers and a high reactor inside the substation. A multi-point equivalent source model of the transformers is constructed to predict the noise distribution in the substation. The accuracy of the developed model is verified by comparing the predicted results with the and measured data. This model is used to explore the influence of sound barrier position and height on its sound insulation performance under different terrain conditions. It is found through the Huygens Fresnel wave theory that the noise reduction effect of sound barrier is the worst on uphill terrain

and the steeper the slope

the weaker the noise barrier'a ability to block noise. In downhill terrain

the noise reduction effect is the best

and the steeper the slope

the stronger the sound barrier's ability to block noise. The conclusions in this paper can provide a reference for plant boundary topography optimization site selection for new substations.
