摘　　要：高压直流换流站可听噪声的环境影响是直流输电急需解决的关键技术问题之一。对高压直流换流站主要噪声源的产生机理和声学特性进行了研究,并对噪声源的频谱特性进行了实测和分析,在此基础上提出了噪声控制措施,将噪声水平控制在国家标准允许范围内,对实际工作具有一定的指导意义。The environmental impact of audible noise in HVDC converter stations is one of the key technical issues needing to be resolved urgently. The generation mechanism and acoustic characteristics of main noise source for HVDC converter station are studied, and the spectral characteristics of the noise source are measured and analyzed. On this basis, the noise control measures are proposed to restrict the noise levels within theallowable range of national standards, which has a guiding signifi- cance for the actual work.
