GE Energy Expands its 1.5-Megawatt Series of Wind Turbines
1.5xle Unit Designed for Low-Wind Areas
HUSUM, GERMANY - September 20, 2005 - GE Energy has expanded its 1.5-megawatt series of wind turbines to include the 1.5xle model, designed for efficient operation in weak wind areas, the company announced today at HUSUMwind 2005.
A prototype of the 1.5xle wind turbine recently was connected to the grid at the Klondike Wind Farm in Sherman County, Oregon to begin its performance testing phase, which is scheduled for completion by the end of the year.
"With the introduction of the 1.5xle, GE's 1.5-megawatt series now is available with the ideal rotor diameter for every wind classification," said Ulrich Uphues, platform manager, 1.5-megawatt series for GE Energy's wind segment.
GE's 1.5se wind turbines feature a rotor diameter of 70.5 meters for strong or class I wind areas; the 1.5sle has a 77-meter rotor diameter, ideal for class II; and the new 1.5xle offers a rotor diameter of 82.5 meters, for class III or weaker wind applications. GE's 1.5-megawatt family of wind turbines also offers an extreme cold-weather package that provides for operation at temperatures as low as -30°C, and in survival mode without operation, at temperatures as low as -40°C.
"The development of the 1.5xle is the latest example of how we continue to improve the capabilities and performance of our 1.5-megawatt wind turbines, which are among the most widely used megawatt-class wind turbines in the global energy industry," said Uphues. "More than 3,300 of these machines have been installed worldwide totaling more than 5,000 megawatts of capacity."
For the prototype 1.5xle unit, a few mechanical adjustments were required to accommodate the larger rotor diameter. "The pitch bearing, pitch system, rotor hub and blades, gears and towers were enhanced to meet the higher demands," explained Uphues.
Test bed trials for the 1.5xle ran for two months, with successful results. The new machine's LM 40 rotor blade has been specifically adapted to meet the operational requirements, and also underwent extreme-load and fatigue testing.
The 1.5xle series is available with tower heights of 58.7, 80 and 100 meters. The tallest version also is available in solid steel form with no concrete foundation.
