摘　　要：城市变电站运转给居民造成的环境噪声污染问题被人们广泛关注,为减小噪声污染、提高降噪效率,进行噪声预测具有重要的实际意义.本文开发一款变电站噪声预测软件,阐述该软件系统的结构、功能、特点及基本算法.采用实测数据及国际主流噪声预测软件Cadna/A的计算数据验证该软件噪声计算结果的准确性.验证结果表明:两款噪声预测软件计算绘制出的噪声地图图像分布趋势相似;变电站噪声预测软件的噪声计算结果与实测数据相比,平均绝对误差约为0.94 dB(A);与Cadna/A软件的噪声计算结果相比,平均绝对误差在1 dB(A)范围内.Environmental noise pollution caused by the operation of urban substation to residents has been widely concerned by people.In order to reduce noise pollution and improve noise reduction efficiency,noise prediction has important practical significance.In this paper,a substation noise prediction software is developed comprehensively,and the structure,function,characteristics and basic algorithm of the software system are described.According to the measured data and the computed data of the international mainstream noise prediction software Cadna/A,the accuracy of noise calculation results of the substation noise prediction software are verified.The results show that the distribution trend of the noise maps generated by the two noise prediction software is similar.Compared with the measured data,the average absolute error of the substation noise prediction software is about 0.94 dB(A).Compared with the noise calculated by Cadna/A software,the average absolute error is within the range of 1 dB(A).
