The annual average wind speed apply more than 4.5m/s
System protection method
When over wind speed(more than 15m/s), furling(folding tail section of nacelle) is working, It protect system by reduced fatigue load on the blade, nacelle and shake the tower and vibration.
Electric brake and 3phase short circuit brake is operates with furling working at the same time, it activated by applying triple safety devices.
