在(zai)本(ben)工程調試過(guo)程中，晶閘管(guan)實(shi)際擊穿的次數較多。主要原因是電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓不穩定(ding)，而(er)晶閘管(guan)的設計(ji)容(rong)量偏小（400A），后將所有(you)晶閘管(guan)更換（700A）后問題得(de)以解決。無功(gong)補(bu)償(chang)(chang)裝(zhuang)置的運(yun)行(xing)(xing)情(qing)況從我風(feng)(feng)場(chang)(chang)目前無功(gong)情(qing)況看(kan)，設備運(yun)行(xing)(xing)良好，多臺風(feng)(feng)機(ji)投入運(yun)行(xing)(xing)后，均能(neng)控制良好的無功(gong)輸(shu)出(chu)，具備良好的無功(gong)調節效果。當電(dian)(dian)(dian)網(wang)出(chu)現(xian)故障(zhang)時(shi)能(neng)夠有(you)效的消除電(dian)(dian)(dian)壓波動對(dui)風(feng)(feng)機(ji)的影響。通過(guo)華能(neng)茂明風(feng)(feng)電(dian)(dian)(dian)一期的基建安裝(zhuang)、調試過(guo)程，以及(ji)SVC型靜態無功(gong)補(bu)償(chang)(chang)裝(zhuang)置的調試、試運(yun)，我們對(dui)風(feng)(feng)力(li)發電(dian)(dian)(dian)系統無功(gong)補(bu)償(chang)(chang)的重要性有(you)了更為深刻(ke)的認識，無功(gong)補(bu)償(chang)(chang)裝(zhuang)置的可靠運(yun)行(xing)(xing)及(ji)配(pei)置，對(dui)風(feng)(feng)電(dian)(dian)(dian)場(chang)(chang)安全、穩定(ding)、運(yun)行(xing)(xing)具有(you)十(shi)分重要的作用。

           電抗器回收鐵芯由高精度的矽鋼片沖壓疊加而成，盡可能避免了三相之間的電感差異，確保電抗器的調諧精度。此外，在諧波污染程度嚴重的電網環境中，充足的鐵芯線性度可承受電容組的反復投切而不造成飽和問題。高溫度等級絕緣層采用 Class H 材料。工作溫度可達 50℃，儲存溫度為 75℃。真空過壓注入整個電抗器單元都是在真空的狀態入絕緣材料，并在過壓的情況下烘干。真空過壓注入保證了電抗繞組與鐵芯結構安全，從而達到降低噪聲、減少震動、增強散熱的目的。電腦控制設計與測試無論是對損耗、尺寸還是環境條件的要求的均可通過設計軟件優化電抗器設計，并提供客戶一個量身定做的產品. 數據庫控制的電抗器測試設備適用于日常的電抗器測試。在型式試驗中宏，一個的容量為 0.9Mvar 的三相諧波發生器可模擬現實電網中含諧波的情況，同時發出基波電流與諧波電流，測試電抗器的效果。同時，在產品的可靠性測試中，發熱與噪聲測試以及過壓測試均是 ABB 電抗器測試的必選內容。
