New dimensions Siemens Wind Turbine SWT-3.6-107 www.siemens.com/wind Answers for energy.

New dimensions The SWT-3.6-107 wind turbine is one of the largest models in the Siemens Wind Po­ er product portfolio. It was specifiw cally designed for offshore applications, but works equally well onshore. The 107-m rotor has a swept area of 9,000 square meters, and with the advanced aero­ ynamics of the B52 d I ­ntegralBlade® technology the energy yield sets new standards. The SWT-3.6-107 machine is ideal for offshore markets worldwide. A rugged, conservative structural design, automatic lubrication systems with ample supplies, climate control of the internal environment, and a simple generator...

Technical description General design The turbine design combines a solid and conservative approach with high-performance technical features and innovative safety and monitoring systems. Rotor The SWT-3.6-107 turbine has a three-bladed rotor with pitch regulation for power output optimization and control. The rotor speed is variable in order to maximize the aerodynamic efficiency, and speed compliance during power ­ egulation minimizes the dynamic loads on the r transmission system. Blades The B52 blades are made of fiberglass-­ einforced epoxy r in Siemens’ proprietary IntegralBlade® manufacturing...

Controller A standard industrial computer is the ­ asis of the turbine b controller. The controller is self-diagnosing and includes ­ a keyboard and display for easy status readout and adjustment of settings. Power conversion The NetConverter® power conversion ­ ystem allows gens erator operation at variable speed, frequency and voltage while supplying power at constant ­ requency and voltage f to the MV transformer. The power conversion system is ­ a modular arrangement for easy maintenance. Power is transferred by DC from the rectifier installed in the nacelle to the inverter installed in the...
