摘要
近年来架空线路可听噪声逐渐成为限制输电线路建设的重要电磁环境问题。为此总结了交直流输电线路可听噪声研究现状,包括可听噪声的产生机理、测量以及评估,着重分析了直流线路与交流的主要区别和研究难点。结果表明目前对于可听噪声的研究已经取得了一定进展,但是交直流线路电晕效应之间存在较大差异且认识不足,造成这些差异的主要原因是直流线路离子电场的影响;分析表明未来仍然可以利用电晕笼研究直流线路的电晕效应,关键在于建立电晕笼与实际线路在合成电场上的关联。
In recent years,the audible noise of overhead lines has gradually become an important electromagnetic environment problem limiting the construction of lines.Therefore,this paper summarizes the research status of audible noise in AC and DC transmission lines,including the generation mechanism,measurement and evaluation of audible noise,and focuses on the analysis of the main differences and research difficulties between AC and DC lines.The results show that some progress has been made in the study of audible noise,but the corona effect of AC and DC lines is very different and not well understood.The main reason for the difference is the influence of the ionic electric field of DC lines.The analysis shows that corona cage can be used to study the corona effect of DC circuit in the future,and the key is to establish the correlation between corona cage and actual circuit in the synthetic field.
