中文摘要:
      随着环保意识的不断加强,直流换流站的噪声问题正越来越受到重视。目前直流换流站的环境预测软件几乎都是国外进口的通用预测软件,该文对一款由国内自主开发的直流换流站环境噪声计算软件的软件结构、功能模块、程序编制及基本算法等方面进行了阐述,并对其预测水平进行了研究,结果表明:与国外预测软件SoundPlan与Cadna/A相比,该软件单点噪声值误差在1.5dB(A)范围以内,尤其与Cadna/A相比,绝大多数监测点误差都在0.5dB(A)左右以内;绘制的网格噪声分布图趋势相似,颜色分布合理;该软件达到同类国外预测软件水平,具有较大的实际应用价值和推广价值。
英文摘要:
      Along with continuously strengthening environmental awareness in China,the noise pollution problem of DC converter station has been attached increasing importance.The prediction software of environmental noise for DC converter station is almost imported at the present time.This paper presents new software for the noise calculation of DC converter station,which is fully self-developed.By expounding the structure,function module,programming,basic algorithms of the software and studying the level of prediction accuracy,the results show: compared with the foreign software,such as SoundPlan and Cadna/A,the error of the software for single point calculation is less than 1.5 dB(A),and especially it is 0.5 dB(A) less than Cadna/A's error;the trend of noise distribution map is alike and the color dis-tribution is reasonable;the software achieves the same level of the similar foreign prediction software,and it has greater value of practical application and popularization.
