摘　　要：500 kV交流输电线路是国家电网的重要组成部分,承担着汇集发电厂电能并与下级电网连接的功能。可听噪声是500 kV交流输电线路的主要环境影响之一。为了对500 kV交流输电线路的声环境影响进行定量分析,本文筛选出2个预测公式,并将其预测结果和噪声实测值进行比较。结果显示,2个公式均适用于500 kV交流输电线路噪声的预测。The 500 kV AC transmission line is an important part of the national power grid,which bears the function of collecting power from the power plant and connecting it to the lower-level power grid.Audible noise is one of the main environmental impacts of the 500 kV AC transmission line.In order to quantitatively analyze the acoustic environmental impact of 500 kV AC transmission lines,two prediction formulas were screened out,and the prediction results were compared with the measured noise values in this paper.The results show that both formulas are applicable to the prediction of 500 kV AC transmission line noise.
