摘要
随着高压直流输电的快速发展,换流站交流滤波场的噪声问题也日渐突出。本文针对国家电网某换流站750 kV BP11/BP13交流滤波场进行了噪声和振动测量,总结分析了噪声的频谱特性,探究了各频率噪声的主要来源,并对空间分布特性进行了讨论,发现交流滤波场的噪声分布不具有对称性,并且随着噪声频率升高声场的干涉现象也逐渐突出。
With the rapid development of HVDC the issue of noise of AC filter in converter station is becoming more and more serious. In this paper, the noise spectrum feature is analyzed through both noise and vibration measurement of equipment in 750 kV BP11/BP13 AC filter field at certain converter station in SGCC , the main source of the noise at each frequency is studied and the space distribution feature is discussed. It is found that the noise distribution of AC filter field is asymmetrical and becomes serious with the interference phenomenon of increase of noise frequency.
