2007年6月19日，ABB正在為歐洲，非洲和美國幾個高壓直流連接點更新正在老化的控制系統(tǒng)，為快速傳輸工程和縮短傳輸干擾設置新記錄。 20世紀七八十年代，是高壓直流連接應用近30年的時候。在近30年的不分日夜的運行后，其相似的控制系統(tǒng)——盡管仍然可以正常運作，但確實需要對其更新來阻止未知事故的發(fā)生。 最近，ABB已經(jīng)選擇用MACH2™控制和保護系統(tǒng)來代替5號HVDC連接實現(xiàn)安全的實用性，參加新功能性確保能夠再正常運行30年或更久。 美國有兩處需要更新——在北達科他州和明尼蘇達州之間的CU和Square Butte高壓直流輸電連接，這兩處更新已經(jīng)完成，對快速傳輸和最小化干擾已經(jīng)進行了工業(yè)設置。 三個新合同 ABB的又一創(chuàng)舉，基于模塊設計的HVDC控制系統(tǒng)——MACH 2™，具備卓越的接縫能力，也是Great River Energy公司傳輸工程經(jīng)理記述其省時無事故安裝和新控制系統(tǒng)試運行特殊性的原因 作為ABB一系列的成功成果，ABB在去年贏得了三個合同：在丹麥和挪威之間更新Skagerrak 1&2 HVDC控制系統(tǒng)，在莫桑比克和南非之間更新Cahora Bassa HVDC 連接和在新墨西哥州使連接西部和德州電網(wǎng)相互連接的Blackwater緊密發(fā)電站。 MACH 2™是為發(fā)電應用而專門設計的。對于HVDC和FACTS它是市場上具備高性能且最有用的控制和保護系統(tǒng)，在世界范圍內(nèi)已經(jīng)安裝了400多個。 original text [COLOR=#708090]ABB modernizes HVDC control systems in record time 2007-06-19 - ABB is upgrading aging control systems at several high voltage direct current links in Europe, Africa and the United States, setting new records for rapid project completion and minimal transmission disturbance. The 1970s and 1980s generations of high voltage direct current （HVDC） links are approaching the age of 30. After almost three decades of round-the-clock operation, their analog control systems – although still in perfect working order – are in need of modernization to prevent unforeseen outages from occurring. Recently, ABB has been selected to replace the control systems of five HVDC links with its MACH 2™ control and protection system to secure availability, add new functionality and ensure another 30 years or more of trouble-free performance. Two upgrades in the United States – the CU and Square Butte HVDC links between North Dakota and Minnesota - have already been completed and have set industry benchmarks for rapid project completion and minimal transmission disruption. Three new contracts An “astonishing achievement made possible by ABB’s modular-based HVDC control system, MACH 2, together with the dedication and excellence of a joint workforce” is how Great River Energy’s transmission engineering manager described the exceptionally short and uneventful installation and commissioning of the new control system. As a result of these successes ABB has been awarded three contracts within the past year to upgrade control systems at the Skagerrak 1&2 HVDC interconnector between Denmark and Norway, the Cahora Bassa HVDC link between Mozambique and South Africa, and the Blackwater back-to-back station in New Mexico which interconnects the Western and Texas power grids in the United States. MACH 2 is designed specifically for converters in power applications. It is the highest performance and most used control and protection system for HVDC and FACTS （flexible AC transmission systems） on the market, with more than 400 installations in operation worldwide.[/COLOR]
