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
