摘　　要：随着中国经济的发展和人民生活水平的提高,国家对环境保护的要求越来越严,治理换流站运行噪声对周边环境的影响问题迫在眉睫。为了降低换流站内交流滤波场噪声,南方电网对某±500 kV换流站交流滤波场主要设备进行了试验性改造,并对改造的滤波器噪声情况进行了跟踪验证测试,取得了明显的效果。文中介绍了改造换流站交流滤波场主要设备历史噪声测试和改造验证测试情况,并简要分析了交流滤波器组主要设备改造前后的噪声变化,总结了一些设备噪声改造经验。指出低噪声滤波电容器在降噪改造中的关键作用,供今后类似改造工程参考。To reduce the noise of AC filter capacitor installation in converter station,the Southern Power Grid experimentally modified the AC filter capacitor installation in a ±500 kV converter station,and detected the noise of the modified installation to verify that significant noise reduction has been achieved. This paper analyzes the difference between the historical noise test data of this filter capacitor installation and the ones after the modification,and sums up some experiences about noise reduction of converter station. It is pointed out that low noise AC filter capacitor plays a key role in modification for noise reduction of converter station.
