CAPACITY FACTOR LEADERSHIP IN CLASS S WINDS

GE Renewable Energy has invested more than $2 billion in next-generation wind turbine technology to provide more value to customers—whether at the turbine, plant or grid level. Through the use of advanced analytics, GE Renewable Energy is redefining the future of wind power, delivering with proven performance, availability and reliability. With the internet, we can help customers manage the variability that comes with this resource for smooth, predictable power. Our onshore product portfolio includes wind turbines with rated capacities from 1.6-3.4 MW and flexible support services that...

CAPACITY FACTOR LEADERSHIP IN HIGH WIND SITES GE’s 1.85-87 Wind Turbine GE’s 1.85-87 wind turbine is designed for Class S winds, targeting 8.5 m/s, and offering an 11% increase in swept area and an extra 150 kW output at rated wind speed compared to the 1.6-82.5 turbine—resulting in a 10% increase in Annual Energy Production (AEP) at 8.5 m/s. This increase in blade swept area allows greater energy capture and extra output at rated wind speed, and drives improved project economics for wind developers. GE’s proprietary Advanced Loads Control allows siting of the 1.85-87 wind turbine in Class...

Technical Description GE’s 1.85-87 wind turbine is a three-blade, upwind, horizontal axis wind turbine with a rotor diameter of 87-meters. The turbine rotor and nacelle are mounted on top of a tubular steel tower, providing a hub height of 80-meters. The turbine uses active yaw control to keep the blades pointed into the wind. The 1.85-87 wind turbine is designed to operate at a variable speed and uses a doubly fed asynchronous generator with a partial power converter system. Specifications: • Designed and certified to IEC 61400-1: – Class S: 8.5 m/s average wind speed; 14% turbulence...

CAPACITY FACTOR LEADERSHIP IN HIGH WIND SITES

Construction Towers: Tubular steel sections provide a hub height of 80 meters. Blades: Proven 42-meter blades. Drivetrain components: GE’s 1.85-87 uses proven design gearboxes, mainshaft, and generators with appropriate improvements to enable the larger rotor diameter in Class S winds. Enhanced Controls Technology The 1.85-87 wind turbine employs GE’s patented Advanced Loads Control. This feature reduces loads on turbine components by measuring stresses and individually adjusting blade pitch. Condition Monitoring System GE’s Condition Monitoring System* (CMS) and SCADA Anomaly Detection...
