摘要

文中以某±800 kV直流受端换流站为研究对象

采用基于波束形成的声成像测量技术

对该直流换流站整站关键位置可听噪声进行现场测试并获得主要噪声源的空间位置和频率特性。测试与分析结果表明

交流滤波场主要噪声源为电抗器组和电容器组

电抗器组区域噪声在562～708 Hz范围内存在较明显峰值

电抗器组与电容器组的噪声存在干涉现象。此外

交流场架构由于电晕放电产生的噪声同样不容忽视;直流滤波场最主要噪声来自于平波电抗器

存在明显高次谐波引起的噪声成分;换流变压器区域主要的噪声源为布置在换流变外部的冷却风扇阵列

以低频噪声为主;站用变区域最大噪声点为变压器本体

频谱主要分布在100 Hz及其倍频上

以291～375 Hz内频率分量较大;调相机外冷水系统和阀冷系统的最大噪声大部分来自于喷淋水拍打底部水盘产生的噪声。

Abstract

In this paper

a beam-forming acoustic imaging technology is applied to identify the spatial position and frequency characteristics of the main noise source on the key position of a ±800 kV DC converter station. The test results show that the main noise sources of the AC filter field are the reactor group and the capacitor group

the noise of the reacitor group has obvious peak value at 562～708 Hz

and there is interference in the noise between reactor group and capacitor group. In addition

the noise generated by corona discharge in AC field architecture should not be ignored. The main noise of DC filter field is from flat wave reactor. The main noise source in the converter transformer area is the cooling fan array arranged outside the transformer

and the low-frequency noise is the main noise.The maximum noise source in the region of substation transformer is the transformer body. The frequency spectrum shows that the frequency is mainly distributed on 100 Hz and its frequency multiplication

with a larger component of 291～375 Hz. Most of the maximum noise of the external cold water system of the condenser and the valve cooling system is generated by sprinkling water on the bottom water pan of the cooling tower.
