近日，中(zhong)國電建所屬湖(hu)北工(gong)程公司設(she)計院參(can)與設(she)計的北京冬奧會重(zhong)點配套工(gong)程——張北柔(rou)性直流(liu)電網試(shi)驗示范工(gong)程首次成功實現四端聯(lian)網方式帶電運行，標志著世界首個(ge)四端柔(rou)性直流(liu)環形電網組網成功。
湖北工(gong)(gong)(gong)(gong)程公(gong)司負責張(zhang)北-北京線(xian)(xian)(xian)路(lu)中張(zhang)北換流站(zhan)出線(xian)(xian)(xian)段(duan)(duan)的設(she)(she)計(ji)工(gong)(gong)(gong)(gong)作，包含87公(gong)里(li)±500千伏雙極(ji)直流線(xian)(xian)(xian)路(lu)的設(she)(she)計(ji)工(gong)(gong)(gong)(gong)作和2個工(gong)(gong)(gong)(gong)程設(she)(she)計(ji)專題的研究(jiu)工(gong)(gong)(gong)(gong)作。湖北工(gong)(gong)(gong)(gong)程公(gong)司設(she)(she)計(ji)院(yuan)設(she)(she)計(ji)段(duan)(duan)線(xian)(xian)(xian)路(lu)起點位于(yu)河北省張(zhang)家口市張(zhang)北縣(xian)(xian)公(gong)會鎮西側約2公(gong)里(li)處(chu)的張(zhang)北換流站(zhan)，終點位于(yu)崇禮宣(xuan)化縣(xian)(xian)界處(chu)，經過的行政區包括張(zhang)家口市張(zhang)北縣(xian)(xian)、萬(wan)全縣(xian)(xian)和崇禮縣(xian)(xian)，沿線(xian)(xian)(xian)地形(xing)以平丘和山(shan)地為主。線(xian)(xian)(xian)路(lu)導線(xian)(xian)(xian)采用(yong)4×720截(jie)面(mian)導線(xian)(xian)(xian)，地線(xian)(xian)(xian)采用(yong)2根光纜，全部(bu)采用(yong)金屬回流方式運行。工(gong)(gong)(gong)(gong)程于(yu)2017年(nian)2月啟動(dong)初步設(she)(she)計(ji)，2017年(nian)6月完(wan)成現場終勘定位，2018年(nian)2月全面(mian)開工(gong)(gong)(gong)(gong)建(jian)(jian)設(she)(she)，并于(yu)2019年(nian)12月完(wan)成全部(bu)建(jian)(jian)設(she)(she)。在工(gong)(gong)(gong)(gong)程建(jian)(jian)設(she)(she)階段(duan)(duan)，設(she)(she)計(ji)院(yuan)工(gong)(gong)(gong)(gong)程組人員始終提(ti)供優質工(gong)(gong)(gong)(gong)代(dai)服務(wu)，助力工(gong)(gong)(gong)(gong)程順利投產送電。
該(gai)工(gong)(gong)(gong)程是(shi)世(shi)界(jie)(jie)首個真正具(ju)有網(wang)絡(luo)特(te)性的(de)直(zhi)(zhi)流(liu)電網(wang)工(gong)(gong)(gong)程，創(chuang)(chuang)新引領和(he)示范(fan)意義重(zhong)大(da)。張(zhang)北柔直(zhi)(zhi)工(gong)(gong)(gong)程在建(jian)設(she)過程中創(chuang)(chuang)下(xia)的(de)12項世(shi)界(jie)(jie)第一，使工(gong)(gong)(gong)程的(de)核心技(ji)術和(he)關鍵設(she)備均(jun)實(shi)現國(guo)際首創(chuang)(chuang)，提高(gao)了我(wo)國(guo)電工(gong)(gong)(gong)裝備制(zhi)造業的(de)自主創(chuang)(chuang)新能(neng)力(li)(li)和(he)國(guo)際競(jing)爭(zheng)力(li)(li)，并將繼續(xu)鞏固、擴大(da)我(wo)國(guo)在世(shi)界(jie)(jie)直(zhi)(zhi)流(liu)輸(shu)電領域(yu)的(de)技(ji)術領先優勢，助力(li)(li)我(wo)國(guo)電力(li)(li)技(ji)術持續(xu)進步。
作(zuo)為2022年(nian)北京冬季(ji)奧林匹克運動(dong)會的(de)重點配(pei)套工(gong)程(cheng)(cheng)之一，張北柔直工(gong)程(cheng)(cheng)可實現冬奧會場館100%全(quan)清潔(jie)電力(li)供(gong)應。工(gong)程(cheng)(cheng)投(tou)運后(hou)，每年(nian)可向(xiang)北京地區(qu)輸送清潔(jie)電量約(yue)225億千瓦時，大約(yue)相當于北京市(shi)年(nian)用電量的(de)十分之一，折合(he)每年(nian)節約(yue)標煤780萬(wan)噸(dun)、減排二氧化碳2040萬(wan)噸(dun)，充分體現了“綠色奧運、低碳奧運”的(de)理念。
