摘　　要：为降低变电站产生的噪声影响,同时避免站外环境发生变化导致新增噪声影响,可采用绘制噪声地图的方式。以某220kV变电站为例,通过Cadna/A软件建模预测,同时叠加区域噪声背景值,获取了变电站初期、终期规模建成后站内外噪声分布情况,据此绘制了噪声地图,分析了站外现有建筑物及规划区域的噪声状况,并对其中的噪声超标区域,从规划角度提出了优化方案。通过噪声地图的动态管理,可为实现区域噪声达标、环境噪声管理、优化城市规划等提供科学依据。Noise maps can be used in decreasing noise impact of substations,and avoiding increased noise impact due to changes of surroundings.Taking a 220kV substation as example,noise distribution inside and outside the substation at initial and final scale was obtained by using Cadna/A software modeling to predict and superposing the background value of regional noise.Noise impact outside the substation and planning area was assessed,and optimization scheme was proposed from the perspective of planning for the areas with excessive noise.The dynamic management of noise map can provide scientific basis for regional noise reaching the standard,environmental noise management and urban planning optimization.
