Outstanding efficiency Siemens Wind Turbine SWT-2.3-93 Answers for energy. SIEMENS

The SWT-2.3-93 wind turbine is the highest- productivity member of our 2.3 MW turbine Based on more than 25 years of leading- edge design and construction, it is suitable for almost any type of application, both onshore and offshore. A rugged, conservative structural design, automatic lubrication systems with ample supplies, climate control of the internal environment and a simple generator system without slip rings provide exceptional reliability at long service intervals. Power conversion is implemented with Siemens' unique NetConverter® system, offering maximum flexibility in the turbine response...

General design graded version of the classical SWT-2.3- blade, a rotor diameter of 93 m, and hence a 25 percent increase of the swept area relative to the SWT-2.3-82 wind bladed rotor with pitch regulation for power output optimization and control. The rotor speed is variable in order to maximize the aero-dynamic efficiency, and speed compliance during power regulation minimizes the dynamic loads The B45 blades are made of fiberglass- reinforced epoxy in Siemens' proprietary IntegralBlade® manufacturing process. In this process, the blades are cast in one piece, leaving no weak points at glue...

The yaw gear motors are fitted with brakes, assisting the passive friction of the bearing for stable maintenance of the A standard industrial computer is the basis of the turbine 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 system allows generator operation at variable speed, frequency and voltage while supplying power at constant transformer. The power conversion system is a modular arrangement for easy maintenance. tapered tubular steel tower. The tower...
