户外与半户内布局变电站的环境噪声分析研究

Analysis and research on environmental noise of outdoor and semi-indoor layout substations

变电站的低频噪声是污染人居环境的一大因素,变电站噪声的控制非常重要。本文通过对两2座布局分别为户外和半户内的变电站进行环境噪声模拟,对比分析了其噪声的空间分布情况与声压级大小。在采取增高围墙、增设部分隔声罩等措施后,继续通过模拟,比较分析环境噪声差异,得出半户内的空间布局比户外空间布局能更有效地控制变电站环境噪声。这一对比分析可以为变电站的空间布局设计提供一定的借鉴意义。

Low-frequency noise in substations is a major factor that pollutes the living environment.Control of substation noise is very important.This paper analyzes the spatial distribution of noise and the sound pressure level of two substations with outdoor and semi-indoor layouts.After taking measures such as increasing the height of surrounding wall and adding some sound insulation enclosures,we continued to use simulation to compare and analyze the difference of these two substations in environmental noise.It was concluded that the semi-indoor layout can more effectively control the environmental noise of the substation than the outdoor layout.This comparative analysis can provide some reference for the spatial layout design of the substation.
