摘要

高压直流输电系统中

随输送电压的升高

换流站噪声问题越来越严重。而交流滤波场中的滤波电容器装置是主要的噪声源之一

其降噪需求也越来越高。本文通过对电容器表面振动进行实测

建立单台的电容器噪声仿真模型并进行简化

进而建立多台电容器的噪声仿真模型。利用该仿真模型对不同底面间距的4台电容器进行仿真分析

得出当底面间距约为某一频率空气中声波的半波长奇数倍时

该频率下电容器装置的噪声声功率最低。

Abstract

With the increase of transmission voltage in HVDC system

the noise of converter station is becoming more and more serious. The filter capacitor in AC filter field is one of the main noise sources

and its noise reduction demand is higher and higher. In this paper

the noise simulation model of one capacitor is established by measuring the surface vibration and simplified

and then the noise simulation model of multiple capacitors is established. By using this model

four capacitors with different distance between bottoms are simulated and analyzed

and the noise power of the capacitors is lowest when the distance between bottoms is about odd times of the half wavelength.
