Product Name: SWT-1.3-62 Wind Turbine

Product Description

With more than 1100 SWT-1.3-62 turbines installed globally the SWT-1.3-62 turbine offers a widely-tested, reliable power solution that provides you with safe and clean energy. Rotor The rotor of the SWT-1.3-62 turbine is a three blade cantilevered construction, mounted upwind of the tower. The power limitation is regulated by active stall regulation according to our proprietary CombiStall® system. Blades The blades are made of fiberglass reinforced epoxy and are manufactured by Siemens in a single operation, using our patented IntegralBlade® process. No glue joints between spars and shells, no weak points, no easy access for water or lightning. The aerodynamic design of the blades represents state-of-the-art wind turbine technology, and the blades have been thoroughly tested at Siemens' test site under both static and dynamic loadings. The blades are mounted on pitch bearings and can be feathered 90 degrees for shutdown purposes. Each blade has its own independent fail-safe pitching mechanism capable of feathering the blade under any operating condition, and allowing fine-tuning to maximize power output. Gearbox and Brake The gearbox is a custom-built 3-stage planetary - helical design, mounted on the nacelle with flexible rubber bushings, thereby providing a compact high-performance construction and the lowest possible noise level. The gearbox is fitted with a fail-safe mechanical brake at the high-speed shaft. Generator The generator rotor construction and stator windings are specially designed for high efficiency at partial loads. The generator is fitted with a separate thermostat-controlled ventilation arrangement and by ensuring a very efficient surface cooling the generator can be operated at temperatures well below the normal level of the standard insulation class, thereby providing the best possible lifetime of the winding insulation. Tower The SWT-1.3-62 turbine is mounted on a tapered tubular steel tower. The tower has internal ascent and direct access to the yaw system and nacelle. Controller The turbine controller is a microprocessor-based industrial controller; similar to the type used in other Siemens wind turbines. The controller is complete with switchgear and protection devices. It is self-diagnosing and has a keyboard and display for easy readout of status and for adjustment of settings. Operation The turbine operates automatically under all wind conditions. When the wind speed increases from calm, the turbine will self-start at about 4 m/s average wind speed. The small generator winding remains connected to the grid up to approximately 7 m/s wind speed. At higher wind speeds, the generator switches to the main winding. The wind turbine output increases roughly linearly with the wind speed until the wind reaches 13-14 m/s. Here, the power is limited at rated power by CombiStall®. Safety system The turbine has several redundant levels in the safety system, including an independent pitch system for each of the blades, and as a result the turbine can shut down safely from any operational condition. Remote Control The turbine is equipped with the unique WebWPS SCADA system. The system offers long-distance control and a variety of status views and useful reports from a standard internet web browser. Grid compliance The SWT-1.3-62 turbine can be supplied with an automatic power factor correction system that makes it compliant with even very demanding grid codes and the turbine has ride-through capability for all normal faults.
