| 摘 要： | 根据直流换流站滤波电容器塔架噪声的属性对竖直线声源的算法进行对比分析，提出对竖直线声源进行单独改进优化划分. 通过对使用不同划分长度的计算结果进行比较，确定恰当的长度值. 基于改进算法开发的噪声预测软件与商品软件的比较表明，改进后的预测结果更加准确合理，提高了电容器塔架的噪声衰减预测的计算精度.

| Abstract: | According to the noise property of capacitor tower in DC converter station,we compare the algorithms for vertical linear acoustic sources,and propose an improved method of optimal division of vertical linear acoustic sources alone.The method chooses a proper value of the division length by comparison.An algorithm is developed based on the proposed method,giving better accuracy of noise attenuation prediction of capacitor tower and more reasonable results than a commercial software product. |
