1.5 MW Series Wind Turbine Proven Results ... Adaptable Solutions When it comes to "megawatt-plus" technology, our proven 1.5 MW wind turbine continues to raise the bar. From ongoing technology investments in reliability and efficiency, to more cost effective and versatile configurations, it need not rest on its past successes. Today, with over 5,000 units in operation worldwide, the 1.5MW continues to be one of the world's most widely used wind turbines in its class. Features & Benefits The 1.5 MW machine is active yaw and pitch regulated with power/torque control capability and an asynchronous generator. It uses a bedplate drive train design where all nacelle components are joined on a common structure, providing exceptional durability. The generator and gearbox are supported by elastomeric elements to minimize noise emissions. GE offers quality manufacturing, experienced power plant design and engineering, development expertise, creative financing options, experienced operations and maintenance and responsive and reliable customer service. Its wind technology has been used in world-class projects around the globe. 1.5 MW Wind Turbine Technical Specifications Operating Data   1.5sle 1.5sl 1.5s 1.5se Rated capacity 1,500 kW 1,500 kW 1,500 kW 1,500 kW Cut-in wind speed 3.5 m/s 3.5 m/s 4 m/s 4 m/s Cut-out wind speed 600 s average 25 m/s 20 m/s  WZ II: 22 m/s WZ III, IEC II: 25  m/s 25 m/s Cut-out wind speed 30 s average IEC s: 28 m/s WZ II: 23  m/s  WZ II: 25 m/s WZ III, IEC II: 28  m/s IEC I: 28 m/s Cut-out wind speed 3 s average IEC s: 30 m/s  WZ II: 25  m/s  WZ II: 27 m/s WZ III, IEC II: 30  m/s IEC I: 30 m/s Cut-back-in wind speed 300 s average IEC s: 22 m/s  WZ II: 17  m/s  WZ II: 19 m/s WZ III, IEC II: 22  m/s IEC I: 22 m/s Rated wind speed 12 m/s 12 m/s 12 m/s 12 m/s Rotor   1.5sle 1.5sl 1.5s 1.5se Number of rotor blades 3 3 3 3 Rotor diameter 77 m 77 m 70.5 m 70.5 m Swept area 4,657 m2 4,657 m2 3,904 m2 3,904 m2 Rotor speed (variable) 10.1 - 20.4 rpm 10.1 - 20.4 rpm 11.1 - 22.2 rpm 11.1 - 22.2 rpm Tower   1.5sle 1.5sl 1.5s 1.5se Hub heights (m) 61.4+ / 64.7+ / 80+ / 85+ 61.4* / 64.7* / 80* / 85* / 100* 64.7* /** / 80* /** / 85* /** / 100* m 52.6*** / 54.7*** / 64.7*** * for WZ II **for WZ III/IEC II ***for IEC I + for IEC s Power Control   1.5sle 1.5sl 1.5s 1.5se Power control Active blade pitch control Active blade pitch control Active blade pitch control Active blade pitch control Operating Limits (outside temperature) · Cold weather light: -4 to 104 °F (-20 to 40 °C) · Cold weather extreme: -22 to 104 °F (-30 to 40 °C)/-40 °C to +50 °C survival without operation Control System · Programmable logic controller (PLC) · Remote control and monitoring system Gearbox · Three-step planetary spur gear system Generator · Doubly-fed three-phase asynchronous generator Braking System (fail-safe) · Electromechanical pitch control for each blade (three self-contained systems) · Hydraulic parking brake Yaw System · Electromechanical driven with wind direction sensor and automatic cable unwind Converter · Pulse-width modulated IGBT frequency converter Tower design · Multi-coated, conical tubular steel tower with safety ladder to the nacelle · Load lifting system, load-bearing capacity more than 441 lbs (200 kg) · Service platform for 100 m hub height (service lift optional) Noise Reduction · Impact noise insulation of the gearbox and generator · Sound reduced gearbox · Noise reduced nacelle · Rotor blades with minimized noise level Lightning Protection System · Lightning receptors installed on blade tips · Surge protection in electrical components Note: subject to technical alterations, errors and omissions Technical Drawing 1.5 MW Wind Turbine Technical Data Annual average wind speed at hub height Standard atmosphere according to DIN ISO 2533,M.S.L Standard Rayleigh distribution and unobstructed air flow Annual average wind speed at hub height. Standard atmosphere according to DIN ISO 2533,M.S.L. Standard Rayleigh distribution and unobstructed air flow. GE's patented dynamic power conversion system with VAR control technology enables the wind turbine to generate reactive power (current leading voltage), providing transmission efficiencies and enhanced voltage stability, which is particularly beneficial in weak grid applications. GE's variable speed operation provides reduced mean torque loads and smaller torque excursions for a given power output compared to constant speed wind turbines. The energy of a gust is stored by accelerating the rotor. This leads to reduced loads, improved transmission efficiencies and performance. Note: specifications subject to possible modification.
