换流站噪声治理方案论证 33l 文章编号:1006—1355(2007)—03 换流站噪声治理方案论证姜在秀,王佐民(同济大学声学研究所,上海200092) 摘要:换流站是远距离输送电能的主要设施,其运行设备产生强烈噪声,严重影响四周居民的正常生活,换流站噪声源点多面广,带有甚高电压,治理难度很大,投资费用很高。在全面测量的基础上, 提出以多种吸声型声屏障为主的治理方案,应用CadnaA软件对各种降噪措施的预估效果进行详细计算、对比分析,探索各项参数对降噪效果的不同影响。经过反复论证,确定经济有效的治理方案。关键词:声学;换流站;噪声;声屏障中图分类号:TM63;TB535 文献标识码:A The proj ectargumentation of converter station noise control JIANG ,WANG Zuo—min (Institute ofAcoustics ofTongji University,Shanghai 200092,China) Abstract:Converter station iSthemain installation totransmitpower at along distance,its facilities willproduce intense noise which willseriously influence normallire ofnearby resident. Noise sources of converter stationdistribute broadly and vary widely,and have high ’noise control isdifficult and the cost the base ofthorough measurement various projects ofnoise control mainly using absorbing barriers are brought effectofdifferent projects puted and analyzed and the effectofdifferent parameters on noise reduction was studied byusing thesoftware ofCadna economical and effectiveproject was chosen afterargumentations.
