Siemens offers the SWT-2.3-82 Wind Turbine. This variable speed wind turbine performs noiselessly and is suitable for locations with noise restrictions.
The upwind type of rotor installed in this wind turbine measures 82.4 m in diameter and offers a swept area of 5,300 m². The blades of this wind turbine are made of fiberglass reinforced epoxy resin. The aerodynamic blades are manufactured utilizing a patented IntegralBlade process in a single operation. The single piece molded blades are made without glue joints between spars and shells, no frail segments and does not allow seepage of water and withstand lightening. The blades, each measuring 40 m in length are offered in light grey and RAL 7035 colors. The pitch mounted blades of this SWT-2.3-82 Wind Turbine from Siemens can be folded to 90 degrees during non operative conditions and each blade incorporates a pitching mechanism to stop the operations during extreme weather conditions.
This wind turbine comprises a helical type of gear box mounted on the nacelle with flexible rubber bushings to reduce noise. The mechanical brake incorporated in the gear box is used for controlling the high speed shaft operations. The asynchronous generator incorporated in this wind turbine is IP54 protected and produces a nominal output of 2300 kW at wind speeds ranging from 13 to 14 m/s. The thermostat controlled ventilation system incorporated in the generator keeps the generator in cooled condition. This generator can be operated even in temperatures below the normal level. The microprocessor-based turbine controller utilized in the Siemens performs self diagnosis operations and the incorporated display and keyboard can be used for adjusting the turbine settings.
This self-starting wind turbine starts its operations at 3-5 m/s wind speed, ceases its operations when the wind speed reaches 25 m/s and withstands a maximum wind speed of 55 m/s. This wind turbine can be operated from remote utilizing a unique WebWPS SCADA system and internet.
