摘要

为分析特高压直流输电线路临近复杂地形时的可听噪声状况

基于镜像法并结合优化模拟电荷法

提出了可用于计算复杂地形情况下特高压直流输电线路可听噪声的方法。该方法的有效性通过实测数据获得了验证。利用该方法仿真分析了不同斜坡角度、斜坡起点离导线距离以及凸凹地形对特高压直流输电线路可听噪声的影响规律

结果表明:地形对直流线路可听噪声的分布特性影响较为明显

在进行直流输电线路可听噪声评估时应适当考虑地形的影响。该计算方法及相应的仿真分析结果可为特高压直流输电线路经过复杂地形时的规划设计作技术参考。

Abstract

In this paper

a way is proposed to analyze and to calculate the audible noise situation of ultra high voltage direct current（UHVDC）transmission lines near the complex terrain

which is based on the image method and combined with optimized charge simulation method. The measured data are given to verify the effectiveness of the proposed method. The method is used to simulate and analyze the different slope angle

the slope distance from slope’s starting point to the transmission lines

and the effect of convex-concave terrain on audible noise of UHVDC transmission lines. The result shows that the terrain has obvious influence on the audible noise

therefore

appropriate consideration should be given to the evaluation of audible noise of UHVDC transmission lines. The calculated method and its relevant simulation analysis results can offer technical reference for the planning and design of the UHVDC transmission lines.
