SWT-2.3-82

Product catalog summary

Overview
The Siemens Wind Turbine SWT-2.3-82 VS is a robust and efficient machine designed for utility-scale wind projects, suitable for both onshore and offshore applications, especially in high wind speed areas or locations with noise restrictions. It incorporates advanced technologies like the NetConverter® system and IntegralBlade® technology.

Technical Description
General Design: The turbine is a high-wind version (IEC Class IA) of the SWT-2.3-93 model.
Rotor: Features a three-bladed rotor with pitch regulation for optimized power output and control, with variable rotor speed to enhance aerodynamic efficiency.
Blades: Made from fiberglass-reinforced epoxy using Siemens’ IntegralBlade® process, ensuring no weak points and high quality.
Rotor Hub: Made of nodular cast iron, providing ample space for maintenance.
Blade Pitch System: Regulates power output and minimizes wind loads during extreme conditions.
Main Shaft and Bearing: Forged in alloy steel, supported by a self-aligning double spherical roller bearing.
Gearbox: Custom-built, three-stage planetary-helical design with cooling and filtering systems.
Generator: Fully-enclosed asynchronous machine with high efficiency at partial loads.
Mechanical Brake: Secondary safety system with hydraulic calipers.
Yaw System: Externally geared ring with electric planetary gear motors.
Controller: Standard industrial computer with self-diagnosing capabilities.
Power Conversion: NetConverter® system allows variable speed operation while maintaining constant output.
Tower: Tapered tubular steel, with optional personnel hoist.

Operation
The turbine operates automatically, starting at wind speeds of 3–5 m/s and reaching rated power at 13–14 m/s. It shuts down if wind speeds exceed 25 m/s, with automatic reset when conditions normalize.

Remote Control and Monitoring
Equipped with the WebWPS SCADA system for remote control and status monitoring, and a Turbine Condition Monitoring (TCM) system for real-time diagnostics.

Grid Compliance
Complies with current grid code requirements, featuring voltage and frequency control and fault ride-through capability.

Technical Specifications
Generator: Asynchronous, 2,300 kW, 690 V, with integrated heat exchanger.
Yaw System: Active.
SCADA System: Web WPS with full turbine control.
Tower: Cylindrical/tapered tubular, 80 m or site-specific height.
Operational Data: Cut-in wind speed 3–5 m/s, nominal power at 13–14 m/s, cut-out wind speed 25 m/s.
Weights: Rotor 54 tons, Nacelle 82 tons.
Rotor: Diameter 82.4 m, swept area 5,300 m², speed 6–18 rpm.
Blades: Type B40, length 40 m.
Transmission System: 3-stage planetary/helical gearbox, ratio 1:91.
Mechanical Brake: Hydraulic disc brake.

General design high-wind (IEC Class IA) version of the classical SWT-2.3-93 wind turbine. threebladed 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 regulation minimizes the dynamic loads on the transmission system. The B40 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 joints and providing optimum quality. The aerodynamic...
