颗粒物捕获电子或离子以空间电荷形式对直流电晕放电产生影响。当前我国的大气污染日益严重,沙尘和霾天气频发。污染物中悬浮颗粒物荷电后带来的空间电荷效应将使高压直流输电线路周围的电磁环境复杂化,因此开展空中悬浮颗粒物对高压直流输电线路电磁环境影响的研究对指导直流输电线路的工程设计具有重要意义。该文对输电线路关于颗粒物空间电荷效应的研究历史进行回顾,并从空间电荷密度分布、颗粒物荷电量及其分布、地面合成电场和离子流密度等方面对已有研究结果进行梳理;对静电除尘、气固两相介质电晕放电和尘埃等离子体3个研究领域内关于颗粒物空间电荷效应的相关文献进行梳理,并对研究结果进行总结;指出当前对输电线路电磁环境影响的实验和理论研究中存在的问题,提出未来研究的建议。
顆粒物捕穫電子或離子以空間電荷形式對直流電暈放電產生影響。噹前我國的大氣汙染日益嚴重,沙塵和霾天氣頻髮。汙染物中懸浮顆粒物荷電後帶來的空間電荷效應將使高壓直流輸電線路週圍的電磁環境複雜化,因此開展空中懸浮顆粒物對高壓直流輸電線路電磁環境影響的研究對指導直流輸電線路的工程設計具有重要意義。該文對輸電線路關于顆粒物空間電荷效應的研究歷史進行迴顧,併從空間電荷密度分佈、顆粒物荷電量及其分佈、地麵閤成電場和離子流密度等方麵對已有研究結果進行梳理;對靜電除塵、氣固兩相介質電暈放電和塵埃等離子體3箇研究領域內關于顆粒物空間電荷效應的相關文獻進行梳理,併對研究結果進行總結;指齣噹前對輸電線路電磁環境影響的實驗和理論研究中存在的問題,提齣未來研究的建議。

Airborne suspended particles trapping electrons and ions give rise to space charges, which has an impact on DC corona discharge and electromagnetic environment of high voltage DC(HVDC) transmission lines. This is called space- charge effect of airborne suspended particles. Presently, severe air pollution and frequent occurrence of sand-dust, fog and haze are increasingly raging through China. The space-charge effect of airborne suspended particles charged by corona discharge will complicate the electromagnetic environment of HVDC transmission lines which is one of the important aspects impacting on the determination of the configuration parameters of the transmission lines. This makes the research on the effects of airborne suspended particles on electromagnetic environment of HVDC transmission lines crucial. Firstly, A detailed review on the research on the space charge-effect of suspended particles in the field of power transmission from the aspects of space charge density, charge of particles, total field ion current density at the ground level was conducted. Further, a summary of the research on the space charge effect in the fields of electrostatic precipitation, corona discharge of two- phase mixture of gas and solid, and dust plasma was presented. In the end, this paper pointed out the problems needed to be solved and gives the suggestions for the future research.
