换流站直流滤波电容器噪声现场测试及特性研究
摘要
直流滤波电容器是换流站的主要噪声源之一。本文对典型±660 k V换流站和±800 kV换流站现场直流滤波器的噪声水平进行了测量
The DC filter capacitor is one of the main noise sources of converter station.In this paper
the noise level of a DC filter for typical±660 kV converter station and±800 kV converter station site is measured
including the sound pressure levels and spectral characteristics of HP12/24 and HP6/42 DC filter in ±660 kV converter station as well as the HP 12/24 and HP2/39 DC filter at ±800 kV converter station.The theoretical analysis for the noise spectrum characteristics of DC filter capacitors is analyzed.It is shown by the theoretical analysis and site measurement results that the sound pressure level at the field fence of the DC filter device is between 60~75 dB
the center frequency of the noise is in the range of 400~2 400 Hz
and the noise level on the casing side of the capacitor bank is significantly higher than the side.The site measurement results are affected by other noise sources
and the spectral characteristic obtained by the measurement is more complicated than the theoretical analysis result.
