摘　　要：随着人们环境意识不断提高,高压直流换流站周边环境噪声越来越受关注。换流站内交流滤波器噪声是关注的重点之一,对交流滤波器进行降噪改造是解决换流站噪声问题的途径之一。本文对南方电网某±500 kV换流站DT12/24交流滤波器组降噪改造过程进行噪声声压级跟踪测试,重点测试并分析滤波电容器塔电容器单元套管方向噪声情况。测试结果表明,对DT12/24交流滤波器组降噪改造可以有效降低交流滤波场及周边环境噪声水平,其结果对滤波器降噪设计和改造提供基础的数据支持。With the continuous improvement of people’s environmental awareness,the ambient noise around HVDC converter station is becoming more and more concerned.The noise of the AC filter in the converter station is one of important problems and the noise reduction renovation for AC filter is one of the ways to solve the noise problem of the converter station.In this paper,tracking and testing of noise sound pressure level for DT12/24 AC filter bank at certain±500 kV converter station of Southern Power Grid is performed,with focus on the test and analysis of noise at direction of the bushing of capacitor unit for the filter capacitor tower.It is shown by the test result that the nose reduction renovation for DT12/24 AC filter bank can effectively reduce the AC filter field and ambient noise level,and its result can provide basic data support for the noise reduction design and renovation of filter.
