日前，從鞍山鋼鐵(tie)第(di)二(er)發電廠(chang)獲悉(xi)，在最近一次CCPP機組(zu)大修中，該(gai)廠(chang)通過自(zi)主(zhu)攻(gong)關(guan)，首次完(wan)成(cheng)以該(gai)廠(chang)為(wei)主(zhu)、外方技術服務為(wei)輔的勵(li)磁系(xi)(xi)統靜態和動態試(shi)驗(yan)(yan)(yan)，解決(jue)了CCPP機組(zu)長期(qi)勵(li)磁系(xi)(xi)統試(shi)驗(yan)(yan)(yan)困難的問題(ti)，并填補(bu)該(gai)廠(chang)勵(li)磁系(xi)(xi)統試(shi)驗(yan)(yan)(yan)的部(bu)分空白。

CCPP發電機(ji)組主要依靠電磁(ci)感應(ying)產生電流(liu)，勵磁(ci)系(xi)統(tong)(tong)作為提(ti)供勵磁(ci)電流(liu)的重要系(xi)統(tong)(tong)，工作狀態(tai)直接影響發電水平。根據(ju)電力(li)系(xi)統(tong)(tong)相關規程規定，機(ji)組勵磁(ci)系(xi)統(tong)(tong)試(shi)(shi)驗(yan)應(ying)配(pei)合機(ji)組大修進(jin)行(xing)。由于該(gai)廠CCPP機(ji)組是從國外引(yin)進(jin)的電機(ji)產品(pin)，與之配(pei)套(tao)的勵磁(ci)系(xi)統(tong)(tong)也為外方配(pei)套(tao)產品(pin)，系(xi)統(tong)(tong)試(shi)(shi)驗(yan)對(dui)(dui)機(ji)組各工況要求條件都非常嚴格且(qie)繁瑣，在機(ji)組投產后的歷(li)次(ci)大修中(zhong)該(gai)廠多次(ci)嘗試(shi)(shi)對(dui)(dui)勵磁(ci)系(xi)統(tong)(tong)進(jin)行(xing)靜態(tai)和動態(tai)試(shi)(shi)驗(yan)，但僅(jin)能完成部(bu)分項(xiang)目(mu)。

今年年初，該廠(chang)CCPP機組(zu)(zu)(zu)(zu)進(jin)行(xing)大修，電(dian)氣繼電(dian)保(bao)護專業組(zu)(zu)(zu)(zu)織技術骨干(gan)成立攻(gong)關小組(zu)(zu)(zu)(zu)繼續嘗試(shi)(shi)對勵磁系統(tong)(tong)進(jin)行(xing)試(shi)(shi)驗(yan)(yan)(yan)。通(tong)過(guo)總(zong)結(jie)(jie)以往試(shi)(shi)驗(yan)(yan)(yan)經驗(yan)(yan)(yan)，全面梳理電(dian)氣圖紙后，他(ta)(ta)們(men)將電(dian)氣、熱工(gong)、集控運行(xing)等各個(ge)專業整合在一起，發揮各自優勢和特(te)長(chang)開展試(shi)(shi)驗(yan)(yan)(yan)。他(ta)(ta)們(men)通(tong)過(guo)分析(xi)機組(zu)(zu)(zu)(zu)啟動條(tiao)件(jian)，明確了(le)系統(tong)(tong)跳(tiao)、合閘(zha)命令邏(luo)輯的先后順序(xu)，找到了(le)控制系統(tong)(tong)檢測(ce)下滿足各種工(gong)況試(shi)(shi)驗(yan)(yan)(yan)的所有(you)條(tiao)件(jian)。此次(ci)試(shi)(shi)驗(yan)(yan)(yan)過(guo)程中，他(ta)(ta)們(men)對勵磁系統(tong)(tong)進(jin)行(xing)了(le)假負(fu)載試(shi)(shi)驗(yan)(yan)(yan)、手(shou)動起勵試(shi)(shi)驗(yan)(yan)(yan)、自動起勵試(shi)(shi)驗(yan)(yan)(yan)、階躍試(shi)(shi)驗(yan)(yan)(yan)等靜態(tai)和動態(tai)試(shi)(shi)驗(yan)(yan)(yan)。試(shi)(shi)驗(yan)(yan)(yan)結(jie)(jie)果(guo)證明該廠(chang)勵磁系統(tong)(tong)性能良好可靠，為機組(zu)(zu)(zu)(zu)的安全穩定運行(xing)提供了(le)有(you)力保(bao)障。
