摘要
针对目前对于换流站可听噪声的治理工作都是在换流站工程建设完成后进行,治理难度较大、费用较高、降噪效果不明显的情况,对换流站可听噪声的先期治理进行了探讨。指出站址的选择应尽量远离居民区和其他噪声敏感区;要合理布置换流站的主要噪声源,如将换流变压器采用"面对面"布置、交流滤波场远离噪声敏感点、适当降低滤波电容器塔架高度;预先控制设备噪声,如电抗器预加有效的隔声罩、换流变压器采用BOX-IN结构;尽量利用换流站设备和其他建筑物的屏蔽效应来阻止声波向声音敏感区传播。
There are problems currently in the treatment of audible noise at HVDC converter stations,such as hard work for the treatment,high cost and not enough good effect,as the treatment has been carried out after the converter stations were built up.Aiming at the problems,this paper discusses the early treatment of the noise,resulting in the following conclusions： to locate the converter stations away from residential areas and the other noise-sensitive areas;to reasonably distribute the main noise sources in a way such as to lay transformers with face to face,to put AC filters far from noise-sensitive spots or to reduce the height of filter capacitor stacks;to make precontrol of the noise of equipments such as with sound insulation cover for reactors,BOX-IN structure for converter transformers;to inhibit the noise propagation towards noise-sensitive areas as much as possible with the shielding effect of the equipments and constructions in the converter station.
