3月(yue)10日，國家電網±500千(qian)伏寶德直(zhi)流工(gong)程極(ji)Ⅱ及雙極(ji)系統調(diao)(diao)試(shi)正(zheng)式啟動，整個調(diao)(diao)試(shi)時間約(yue)17天。
系(xi)統(tong)(tong)調試(shi)(shi)是在換流(liu)(liu)站(zhan)(zhan)(zhan)分系(xi)統(tong)(tong)試(shi)(shi)驗(yan)和站(zhan)(zhan)(zhan)系(xi)統(tong)(tong)試(shi)(shi)驗(yan)完成(cheng)后，在各種(zhong)實際運(yun)行工況下對換流(liu)(liu)站(zhan)(zhan)(zhan)的(de)交(jiao)流(liu)(liu)、直流(liu)(liu)設(she)備進行性(xing)能試(shi)(shi)驗(yan)的(de)一項環節。系(xi)統(tong)(tong)調試(shi)(shi)主要(yao)是校驗(yan)站(zhan)(zhan)(zhan)內一次設(she)備狀態、二次設(she)備動作(zuo)的(de)可靠性(xing)及站(zhan)(zhan)(zhan)間(jian)通(tong)信(xin)的(de)正(zheng)確(que)性(xing)等(deng)。系(xi)統(tong)(tong)調試(shi)(shi)結(jie)束后，工程即可投入試(shi)(shi)運(yun)行。
寶(bao)德(de)直流(liu)工程(cheng)系統調試(shi)(shi)(shi)的(de)內容包括(kuo)：初(chu)始化運(yun)行(xing)試(shi)(shi)(shi)驗(yan)(yan)、保護跳閘試(shi)(shi)(shi)驗(yan)(yan)、直流(liu)穩態運(yun)行(xing)試(shi)(shi)(shi)驗(yan)(yan)、功(gong)(gong)(gong)率(lv)(lv)升降(jiang)試(shi)(shi)(shi)驗(yan)(yan)、階躍響應試(shi)(shi)(shi)驗(yan)(yan)、控(kong)(kong)制模式轉換、裕(yu)度補償試(shi)(shi)(shi)驗(yan)(yan)、無功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)(lv)控(kong)(kong)制試(shi)(shi)(shi)驗(yan)(yan)等共(gong)計132項試(shi)(shi)(shi)驗(yan)(yan)，內容全面涵蓋(gai)極II單極和(he)系統雙極的(de)低功(gong)(gong)(gong)率(lv)(lv)、大(da)功(gong)(gong)(gong)率(lv)(lv)方式下(xia)的(de)運(yun)行(xing)控(kong)(kong)制試(shi)(shi)(shi)驗(yan)(yan)和(he)故障擾動(dong)試(shi)(shi)(shi)驗(yan)(yan)。
據相關調(diao)(diao)(diao)試(shi)(shi)人員介紹，寶德直流工(gong)(gong)(gong)程是(shi)首次采用100%國產化設(she)(she)備(bei)建成的(de)輸電工(gong)(gong)(gong)程，有很(hen)多設(she)(she)備(bei)是(shi)首次應用到直流場中，給系統調(diao)(diao)(diao)試(shi)(shi)工(gong)(gong)(gong)作帶(dai)來(lai)了壓力(li)。此外，為確(que)保該工(gong)(gong)(gong)程4月中旬正(zheng)式投運，整(zheng)個系統調(diao)(diao)(diao)試(shi)(shi)時間(jian)由原來(lai)的(de)40天(tian)縮短(duan)到17天(tian)，這(zhe)同樣增加(jia)了調(diao)(diao)(diao)試(shi)(shi)工(gong)(gong)(gong)作的(de)難度。上述情況要(yao)(yao)求調(diao)(diao)(diao)試(shi)(shi)人員以更仔細的(de)態度、更嚴格的(de)要(yao)(yao)求來(lai)測試(shi)(shi)設(she)(she)備(bei)和系統。
本(ben)次(ci)調(diao)(diao)(diao)試由國(guo)網直流建(jian)(jian)設分(fen)公司組織協調(diao)(diao)(diao)，中(zhong)國(guo)電力科(ke)學(xue)研究院(yuan)(yuan)擔任(ren)系統調(diao)(diao)(diao)試單位(wei)，各(ge)安裝單位(wei)、廠家等配(pei)合。直流建(jian)(jian)設分(fen)公司高(gao)(gao)度重(zhong)視本(ben)次(ci)調(diao)(diao)(diao)試工(gong)作(zuo)，該(gai)公司有關領導(dao)親臨現場指揮調(diao)(diao)(diao)試工(gong)作(zuo)，協調(diao)(diao)(diao)解決調(diao)(diao)(diao)試過程(cheng)中(zhong)遇到的(de)各(ge)種技術(shu)問題，確保工(gong)程(cheng)項目(mu)在(zai)調(diao)(diao)(diao)試階段運轉高(gao)(gao)效規范。電科(ke)院(yuan)(yuan)調(diao)(diao)(diao)試人員分(fen)兩班輪崗(gang)，加班加點進行試驗。
截(jie)至3月15日，寶(bao)德直流工程現場(chang)共進行了71項(xiang)試驗，極Ⅱ低功率(lv)試驗項(xiang)目(mu)均已完成，其余的現場(chang)調試項(xiang)目(mu)正在緊張(zhang)有序進行。
