摘要
变电站与城市居民区的距离越来越近,变电站噪声污染成为环保投诉的重点内容之一。以城区典型户内220kV变电站为研究对象,通过分析其噪声源特性,采用Cadna/A软件对变电站站界噪声进行预测,提出降低主变、电抗和风机等声源噪声和控制声源传播途径的措施,能有效降低噪声的排放,避免噪声对站区周边居民的干扰。
As the distance between substation and urban residential areas becomes closer and closer, the noise pollution of substation becomes one of the key contents of environmental protection complaints. Taking a typical urban indoor 220kV substation as the research object, the noise source characteristics are analyzed, and the station boundary noise of substation is predicted by Cadna/A. Finally, the measures to reduce the noise of main transformer, reactance and fan, and to control the propagation path of sound source are put forward, which can effectively reduce the noise emission and avoid the noise interference to the residents around the station area.
