Circuit breakers

Circuit breakers will help meet growing energy demand in NE China

ABB has been awarded a $5.1m contract to deliver fifteen 550 kV high-voltage dead tank circuit breakers to State Power Northeast Corporation in northeastern China.

The contract will be fulfilled by ABB’s new manufacturing facility in Mount Pleasant, PA, USA. The first seven breakers are to be installed in August 2004 with the remainder slated for October of 2004.

China continues to experience strong economic growth, and is presently undergoing a major restructuring of its electric power industry, with the eastern region of the country acting as a pilot programme prior to the implementation of restructuring throughout the rest of the country. ABB believes that equipment purchases such as this contract are likely to continue as the nation prepares to support wholesale electricity trading. ABB provided similar breakers to Northeast China in 1994 and this order builds on the product quality and field performance established from this relationship. This order also represents the strength of ABB’s global focussed factory approach in capturing a significant share of the international market for dead tank circuit breakers.

Once smitten, thrice buy

For the third time in a decade, Methanex Corp. has signed a contract with Dresser-Rand Company to provide power generation equipment for its methanol facility in Puntas Arenas, Chile.

The contract, which calls for a standard multi-stage steam turbine generator package, is part of the third expansion of the facility. When completed in 2005, Plant 4 will increase the facility’s manufacturing capacity by 840 000 t of methanol per year to a total of more than 3.84m t per year, maintaining its status as the largest methanol-producing complex in the world.

Located at the southernmost tip of Chile, the facility went online in 1988, and was acquired in the early 1990s by Methanex Corporation, a Canadian firm based in Vancouver.The facility expanded in 1996 when Plant 2 was completed, and again in 1999 with Plant 3.For Plants 2 and 3 Dresser-Rand provided both centrifugal compression equipment and steam turbine generator sets.

The Dresser-Rand steam turbine equipment for Plant 4 will be manufactured at the company’s facility in Wellsville, New York, USA and is scheduled to ship to the site in March 2004.

Methanol is a liquid petrochemical that is synthesized under pressure in a catalytic process, usually requiring natural gas as the feedstock. Methanol is used in the production of additives for gasoline and can be used as fuel for fuel cells or for power generation.

Centrax order

Centrax Gas Turbines has received an order from the Fingleton White group in Ireland for the supply of a CX501-KB7 gas turbine powered generator set. The set will provide 5.2 MW of electricity plus heat from the exhaust of the Rolls-Royce turbine for use in the production process at the manufacturing plant of Wyeth Nutritionals near Limerick in Southern Ireland.

A new company, Askeaton Power Limited, has been set up to operate the cogeneration plant and supply the Wyeth factory with power and heat in a new energy centre at the site.

Wyeth is a multinational company involved in the manufacture of pharmaceuticals and healthcare products.

UPS manages college IT power flow

Georgia College and State University, Milledgeville, GA, USA has selected S&C Electric Company’s PureWave uniterruptible power supply (UPS) System to maintain consistent power quality to the computer room supporting its information technology (IT) activities.

Short-duration voltage sags and power outages were adversely affecting the productivity of using the PCs in the college’s main computer room and were also causing problems to the room’s air conditioning system.

The college wanted to increase the number of PCs in the computer room, and it knew that maintaining the power quality to the computers and the requisite additional air conditioning equipment was very important. However, no indoor floor space was available for the power protection equipment.

This summer, a 140 kW, 208 V S&C PureWave UPS System was procured by the college and installed outdoors, along with a back-up generator. Chicago-based S&C’s PureWave UPS System is the only uninterruptible power supply system designed to stand up to harsh outdoor environments. It is rated up to 20 MVA and provides 30 s of protection at 100 per cent load.

Alstom wins contract for mining sites down under

Alstom’s transmission and distribution unit has won a g22m contract from BHP Billiton Iron Ore to connect mining sites situated in the remote Pilbara region of Western Australia to an existing natural gas-fired power station in Newman.

Alstom T&D will supply two 132 kV transmission lines totalling 115 km, and three turnkey substations to be located at BHP Billiton’s new mining site at Junction (Mining Area C), BHP Billiton’s existing mine at Yandi and the Duke power station at Newman.

The Alstom equipment will consist of 145 kV and 72.5 kV circuit breakers and disconnectors, 33 kV GIS (gas insulated) switchgear, transformers, MiCOM protection relays, SCADA and e-terra software systems.

The project will be split into two seperate parts, with the first transmission line between Yandi and Junction scheduled for completion by May 2004. The second line, between Junction and the Newman power station, will be completed by November 2004.
