Correction Method of Noise Directivity for Power Capacitor Towers in Converter Stations
电力电容器是高压直流换流站中的主要噪声源之一,其相干声场在远场表现为明显的指向性,在进行电容器塔噪声计算时必须对其进行指向性修正.研究了电容器塔仿真计算中声源的指向性参数获取、指向性定义、以及指向性三维重构的方法,并采用该方法和Cadna/A软件对某换流站中的交流滤波电容器塔进行了仿真对比计算,结果表明,该方法可以很好地解决电容器塔噪声计算中的指向性修正问题.
Power capacitor is one of the main noise sources in high-voltage direct current converter stations.The coherent sound field of power capacitors exhibit significant directivity in the far field,and directional correction must be applied when calculating the noise from capacitor towers.This study investigates the methods for obtaining directional parameters of sound sources,defining directivity,and reconstructing three-dimensional directivity in the simulation of capacitor towers.The proposed method,along with the Cadna/A software,is used to conduct comparative simulation calculations on an AC filter capacitor tower in a converter station.The results demonstrate that this method effectively addresses the issue of directional correction in capacitor tower noise calculations.
