Vestas V47 Power Curve
Turbine auto starts when wind
speed reaches 4 m/s
Blades pitch to 0 degrees until
about 12 m/s wind speed (WS)
Blades pitch to maintain 660 kw
from 12 to 25 m/s WS
Turbine shutdown is 25 m/s if:
Avg WS > 25 for 100 sec.
Avg WS >70 for 3 sec.

Curtailment Orders
ERCOT -> QSE (PMI in FL) -> FPDC -> Shut down turbines for curtailment
Curtailment Release
ERCOT -> QSE (PMI in FL) -> FPDC -> Start up turbines after curtailment
Voltage Control – ERCOT -> TSP -> operates Capacitor Banks in Sub (18 MVAR Indian

Turbine maintains the power
factor up to.098 by the
controller switching in and
out cap banks as required.
Capacitor banks are located
in the bottom of the turbine.
Each turbine has 4 operating
banks consisting of a total of
225 kvar.

Generator Current Controller
VRCC (Vestas Rotor
Current Controller) ,
both hang on generator
rotor and resistor
basket; black portion is
stationary and talks to
nacelle controller over
serial data link. Rest of
unit rotates at 1800
rpm.
