08年12月27日，高海拔地區特高壓直流輸電線路電暈特性及電磁環境影響的試驗研究在南方電網昆明特高壓試驗研究基地正式啟動。至此，自昆明特高壓試驗基地籌建以來，隨著±1200千伏直流電壓發生器和±800千伏直流試驗線路的投運，依托于特高壓試驗基地的第一批科研項目已正式開展。
該項(xiang)試驗研(yan)究(jiu)(jiu)是圍繞公司重點(dian)科研(yan)項(xiang)目(mu)“高(gao)海拔±800千(qian)伏高(gao)壓(ya)直流(liu)電(dian)(dian)(dian)暈(yun)(yun)特(te)性(xing)(xing)及其(qi)電(dian)(dian)(dian)磁(ci)環(huan)境(jing)(jing)(jing)影(ying)響(xiang)研(yan)究(jiu)(jiu)”進行(xing)的相關實驗。通過試驗，可得到特(te)高(gao)壓(ya)、高(gao)海拔直流(liu)導(dao)線的長期電(dian)(dian)(dian)暈(yun)(yun)特(te)性(xing)(xing)統計規(gui)律，分(fen)析高(gao)海拔地(di)(di)區直流(liu)輸電(dian)(dian)(dian)線路的電(dian)(dian)(dian)暈(yun)(yun)產生機(ji)理，研(yan)究(jiu)(jiu)高(gao)海拔地(di)(di)區導(dao)線結構(gou)、氣象(xiang)條件、運行(xing)電(dian)(dian)(dian)壓(ya)等因素(su)對(dui)(dui)電(dian)(dian)(dian)暈(yun)(yun)特(te)性(xing)(xing)影(ying)響(xiang)的理論模型，建立高(gao)海拔特(te)高(gao)壓(ya)直流(liu)輸電(dian)(dian)(dian)線路電(dian)(dian)(dian)暈(yun)(yun)特(te)性(xing)(xing)和(he)電(dian)(dian)(dian)磁(ci)環(huan)境(jing)(jing)(jing)參數測量標準；對(dui)(dui)比(bi)國內(nei)(nei)外低海拔相關研(yan)究(jiu)(jiu)成果(guo)，分(fen)析海拔對(dui)(dui)特(te)高(gao)壓(ya)直流(liu)輸電(dian)(dian)(dian)線路電(dian)(dian)(dian)暈(yun)(yun)特(te)性(xing)(xing)和(he)電(dian)(dian)(dian)磁(ci)環(huan)境(jing)(jing)(jing)的影(ying)響(xiang)，為國際和(he)國內(nei)(nei)的后續直流(liu)輸電(dian)(dian)(dian)工程提(ti)供借鑒。
