  • The annual average wind speed apply more than 4.5m/s

Technical ensure stability (Safe & Duration)

Control method of generated voltage
When the generator voltage is constant voltage or more,some part of the input voltage turn to a power consumption as Dump Load resistance.
Brake operates by Electric Brake as mechanical, three-phase short circuit brake as electrical.

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.
