Top Reasons for MV Wind- Maximum Energy to the Grid
Typical efficiency for whole electrical drive train (DD with PMSG)
~98% converter efficiency incl. all auxiliaries & filters partial load efficiency >95% already at 10% of rated power
Best MTTR by remote access and special repair concept

Top Reasons for MV Wind- Maximum Generator Control
Generator operation at optimum active and reactive power
Rotor positioning mode (on-site needed for service)
Generator test run (hall test needed for pre-heating, over-speed)
Total over-speed voltage suppression (field weakening)
Active drive train damping leads to lean design of mechanicaldrive train components

Top Reasons for MV Wind- Easy cabling and lowest losses
Easy and quick cabling by the Pfisterer© P3 MV PLUG System
I2R losses significantly lower (>factor 20) compared to 690V system maximum system efficiency

Top Reasons for MV Wind- Full Drive Train Decoupling
Full decoupling of mechanical turbine from the electrical grid
Power dissipation resistors for smooth FRT
Active drive train damping lean design of mechanical components

Top Reasons for MV Wind- Full Grid Code Compliance
Integrated Statcom functionality
Three-level switching topology
Control algorithm harmonic elimination
Start & stop at zero breaker current
Immediate restart after grid failures

Power modules, Cooling Unit, all filters, brake chopper (incl. resistor),generator breaker
Various layouts available: face-2-face, back-2-back, I-shape, T-shape
Electrical section in tower less tower head weight / smallerfoundation
Top Reasons for MV Wind- Modular Design - All on one Level
© ABB Group June 6, 2011 | Slide 12
Top Reasons for MV Wind- System Know-how and Global Footprint of ABB
Advanced protection concept includes transformer, switch gear and whole drive train concept
Inclusion of further components into scope of supply
Maximum customer support due to world-wide presence
