ALSTOM to Supply SVC to Xcel Energy Proven Technology Improves Transmission Grid Stability.Energy Editors/Business Editors EDDYSTONE, Pa.--(BUSINESS WIRE)--April 21, 2003 ALSTOM has won a contract to supply its highly reliable SVC (1) (Switched Virtual Circuit) A network connection that is established at the time the transmission is required and disconnected when the session is completed. technology to Xcel Energy (formerly Northern States Power Company Northern States Power Company (formerly NYSE: NSP) was a publicly-traded S&P 500 electric and natural gas utility holding company based in Minneapolis, Minnesota that is now a subsidiary of Xcel Energy (NYSE: XEL). ). The equipment will strengthen Xcel's network in southwestern Minnesota, where large wind farms are coming on line to provide clean power to the Minneapolis metropolitan area. ALSTOM's static var technology will help stabilize the network and facilitate improved transmission to users. Xcel is one of many utilities in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. experiencing growth in wind farm power generation. The growth is mainly taking place in rural farmland areas. Xcel, therefore, needs a dependable channel through which it can bring this "electrical" crop from the wind farm to the market. By installing ALSTOM's efficient SVC technology at its 115kV Lake Yankton substation in Minnesota, Xcel will be equipped to instantaneously provide reactive power reactive power: see power, electric. support to minimize voltage fluctuations at any given time, particularly during weak ac system conditions. Additional benefits offered by this technology are an increase in power transfer capabilities, regulation of power factor, reduction of losses, and an overall improvement to the steady and dynamic performance of the transmission system. SVC, or Static Var Compensator Static var compensator A thyristor-controlled (hence static) generator of reactive power, either lagging or leading, or both. The word var stands for volt ampere reactive, or reactive power. The device is also called a static reactive compensator. , is a thyristor based technology used since the early 1970's and is part of the family of Flexible AC Transmission System (FACTS) devices designed to be inserted into transmission grids to improve the delivery of power in weak areas of the grid. ALSTOM's SVC system will be directly connected to an existing 34.5 kV bus at the Lake Yankton substation. It will include a Thyristor Controlled Reactor (TCR TCR T cell receptor. ) rated for 85 Mvar and two harmonic harmonic. 1 Physical term describing the vibration in segments of a sound-producing body (see sound). A string vibrates simultaneously in its whole length and in segments of halves, thirds, fourths, etc. filter banks rated 60 Mvar in total to provide the dynamic reactive capability range as required by Xcel. ALSTOM's latest control technology will be used for the precise control of the device. As the sole provider of major equipment on this project, ALSTOM, through its Transmission and Distribution (T&D) Sector, will supply the SVC equipment from its Pennsylvania based factory. The equipment will be in service by the end of April 2004. Brian Pope, President of ALSTOM T&D Inc., said, "This is a fine example of how our technology can adapt to the current demands of the market. With the integration of wind power generation becoming a more common challenge for utilities, we stand ready to assist and facilitate this progression with a superior range of systems, services and products." ALSTOM is positioning itself to become increasingly more involved in opportunities presented by the expanding renewable energy Renewable energy utilizes natural resources such as sunlight, wind, tides and geothermal heat, which are naturally replenished. Renewable energy technologies range from solar power, wind power, and hydroelectricity to biomass and biofuels for transportation. market, not only through its static var technology, but also through its offering of distribution transformers, medium voltage switchgear The term switchgear, used in association with the electric power system, or grid, refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate electrical equipment. and reactors to meet the market's needs.
