D9.0

DeWind D9.02000kW Wind TurbineThe DeWind D9.0 is a three bladed variable speed –variable pitch controlled, upwind wind turbine, with an active yaw system. By using a three stage gearbox a 93m rotor drivesa double-feed induction generator. The generatoris closely matched to a converter in order to feedin high-quality energy into the grid. The converteris equipped with state of the art IGBT (Insulated-Gate Bipolar Transistor) technology. It delivers good power quality and meets the requirements of most Low Voltage Ride Through codes in force worldwide. The pitch system is hydraulically driven, with one cylinder per blade, operating collectively. The blades are made from a highly developed hybrid composite structure including carbon andglass fibers in an epoxy matrix.

Features

› Built on proven technology: An evolutionary design that shares many systems proven on the D8-2000 and D8.2.› Asynchronous generator: The D9.0 operates with very high efficiency at variable rotational speed and therefore produces energy, quietly and effectively at wind speeds starting from below 3 m/s. Rotational speed increases due to gusts are stored and converted into electric power at minimum loads.› Latest IGBT technology (Insulated-Gate Bipolar Transistor): Variable rotational speed operation is enabled through the combination of an Induction Generator with a converter fea- turing the latest IGBT technology. The converter runs in four-quadrant operation.

› Use of carbon fiber spar in rotor blade: The use of carbon fiber provides a lighter and stiffer structure.› eOS SCADA Framework: This system is a set of intelligent networked components for monitoring and supervising via remote con- nection.› Easy data analysis: All data can be accessed easily through platform neutral communica- tion interfaces. So the display of the data as a Microsoft Excel®-file is possible.› Noise Management System This System manages noise emissions from the turbine using customer defined criteria like wind direction, wind speed or time of day. The intelligent control system works with the turbine active power management system to maximize energy production whilst complying with local noise legislations.

D9.1

DeWind D9.12000kW Wind TurbineThe DeWind D9.1 is a three bladed variable speed –variable pitch controlled, upwind wind turbine, with an active yaw system. By using a three stage gearbox a 93m rotor drivesa Permanent Magnet Synchronous Generator (PMG). The PMG is closely matched to a full rated inverter in order to feed in high-quality energy into the grid. The inverter is equipped with state of the art IGBT technology (Insulated-Gate Bipolar Transistor). It provides excellent power quality and can meet the requirements of most Grid Codes. The pitch system is hydraulically driven with onecylinder per blade, operating collectively. The blades are made from a highly developed hybrid composite structure including carbon andglass fibers in an epoxy matrix.

D9.2

DeWind D9.22000kW Wind TurbineThe DeWind D9.2 is a three bladed variable speed –variable pitch controlled, upwind, wind turbine, with an active yaw system. A 93m rotor drives a fixed speed synchronousgenerator with a rated power of 2000 kW. Due toits ability to generate at up to 13.8 kV the generatorcan be directly connected to the grid through asynchronizing switch without the need of powerconversion electronics, converters or a main power transformer. The fixed generator speed is achieved by converting the variable rotational speed from the wind turbine rotor to a constant input speed by using a two stage helical / planetary gearbox and the variable speed Voith WinDrive® hydrodynamic superimposed planetary gearbox. The pitch system is hydraulically driven with onecylinder per blade, operating collectively.
