换流站电力电容器塔噪声指向性的修正方法
Correction Method of Noise Directivity for Power Capacitor Towers in Converter Stations
摘要
Abstract
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.关键词
