The wt5500 turbine solutions are fully designed by AMSC®

and are currently in the process of being certified by Germanischer Lloyd. Comprehensive certification support is available.

AMSC’s Windtec Solutions include wind turbine designs that enable our partners to launch best-in-class wind turbines quickly, effectively and profitably. The wt5500df (doubly-fed) and wt5500fc (full-scale conversion) models have been designed for customers seeking to manufacture 5.5 MW wind turbines with the best in quality design, efficiency and performance. The wt5500 design focuses on the lowest cost of energy and highest reliability, supported by active turbine and condition monitoring.

Capitalize on the rise of offshore wind

wt5500df and wt5500fc

High efficiency for offshore generationThe wt5500 design uses an advanced electrical individual pitch control system design. It is available in 50 or 60 Hz, for various climate conditions and in different hub heights, different rotor diameters and blade types to meet all type classes.

The wt5500df features a doubly-fed, three-phase induction generator. The wt5500fc uses a permanent magnet synchronous generator (PMSG), electrical excited synchronous generator or asynchronous generator with a full-scale converter. The generator works with high efficiency over the entire speed range. This is ensured by the IGBT-based converter with advanced power electronics.

Compliance with international grid codesThe wt5500 wind turbines fulfill the most demanding international grid code requirements and have low voltage ride-through (LVRT)capability.

Real-time information with continuous monitoring and alarm handlingAMSC’s advanced wtCMS condition monitoring system provides continuous monitoring of the key system components. This gives operators real-time information about the turbine status as well as detailed and comprehensive analysis

tools to optimize maintenance activities. The fully integrated system allows intelligent measurement, turbine control interaction and the analysis of monitoring and performance data. In addition, wtSCADA remote operation and wtDataCenter analyzing packages are available to provide a harmonized control system with supervisory control and data acquisition to actively monitor, analyze and operate entire wind parks.
