全球領先的電力自動化集團被加拿大魁北克水電公司選中，為其高壓直流換電站進行升級。有著25年歷史的1000兆瓦的Châteauguay背對背高壓直流輸電站將由ABB負責更新，安裝其控制保護系統——MACH 2。 ABB在高壓直流行業的控制系統更新領域擁有豐富的經驗。由ABB新近更新的項目包括：在美國的Square Butte和CU HVDC 連接，兩個在斯堪的納維亞的Skagerrak高壓直流輸電連接和在南非的阿波羅轉化站正在進行的翻新工程。 魁北克水電公司主要應用可持續的能源進行發電、傳輸和電力分配。公司為魁北克、加拿大其它部分及美國西北部提供電力支持，是世界上最大的水力發電公司之一。 在Châteauguay的新控制保護系統將于2009年4月到5月期間進行試運轉，斷電時間僅為7周。自從電站由兩個板塊組成起，每個板塊將被單獨地翻新，在安裝期間，變電站將維持至少一半的電力供應。 [FONT=times] original text [/FONT] [font=times] ABB to Upgrade Transmission Control for Vital North American Power Interconnector [/font] [font=times][Color=#708090]ABB, the leading power and automation technology group, has been selected by Hydro-Québec, Canada, for an upgrade of a high-voltage, direct current （HVDC） converter station. The 25-year-old 1000-MW （Megawatts） Châteauguay back-to-back HVDC station will be equipped with ABB’s control and protection system, MACH 2. ABB has the widest experience of control system upgrades in the HVDC industry. Recent upgrade projects delivered by ABB include the Square Butte and the CU HVDC links in the U.S., the two Skagerrak HVDC links in Scandinavia and the on-going refurbishment of the Apollo converter station of the Cahora Bassa HVDC link in Southern Africa. Hydro-Québec generates, transmits and distributes electricity, mainly using renewable energy sources. The company provides electricity to customers in Québec, other parts of Canada, as well as to northeastern parts of the U.S. and is one of the world’s largest producers of hydroelectricity. The new control and protection system in Châteauguay will be commissioned during April and May in 2009, with an outage time of only seven weeks. Since the station comprises two blocks and each block will be renovated separately, the station will maintain at least half of its capacity during the installation period. [/color][/font]
