摘　　要：离子流场(包括合成电场和离子流密度)是特高压直流输电线路设计和运行中的重要电磁环境指标。特高压直流输电线路路径长,沿线经过不同海拔、湿度和污染情况的地域,离子流场特性会受到气压、湿度和颗粒物浓度等外部气象因素的影响,进而使得离子流场的建模和计算分析复杂化。综述了高压直流输电线路离子流场特性的研究情况,分析了海拔、湿度和颗粒物对离子流场特性的影响以及研究中存在的主要问题,指明了需要进一步研究的关键内容。可为高海拔、高湿度和高污染地区的高压直流架空线路离子流场建模和特性分析研究提供参考。The ion flow field(including the total electric field and ion flow density) is an important electro-magnetic environmental factor for the design and operation of ultra high-voltage direct-current(HVDC) transmission lines. Because the overhead lines are long and pass different altitude, humidity and air quality regions, the ion flow field can be influenced by external meteorological factors such as air pressure, humidity and particulate matter, which makes the modeling and analysis of ion flow field complicated. This paper reviews the literature on the characteristics of ion flow field of HVDC transimssion lines, and analyzes the effects of altitude, humidity and particles on the ion flow field characteristics, and finally clearly points out the existing problems in the current research and the future research prospects, and are helpful to the modelling and characteristic analysis of ion flow field of HVDC transmission lines in high altitude, high humidity and high pollution areas.
