B. System protection function Over wind speed protection ASP system will send a brake-on signal when it checks that the environment wind speed is over 18m/s. The brake assembly will pull pitch controlled mechanism by pitch controlled rod to make blade stay at negative angle position. ASP hugging institutions will brakes wind turbine after the generator rotating speed drops down. After braking, if ASP checks that the average wind speed is always below 12m/s in 45minutes, it will send brake-off signal, and the ASP will release wind turbine main shaft and pitch controlled mechanism to make wind turbine restart. Over current protection When ASP system check the output current of wind turbine is over 45A, it will send a brake-off signal to stop wind turbine and output an alarm signal. Over voltage protection When ASP system check the output voltage of wind turbine is over 560VDC, it will send a brake-off signal to stop wind turbine and output an alarm signal. Power-fail of power grid protection When ASP system check the power grid is power off, it will send a brake-off signal to stop wind turbine and output an alarm signal. After the power grid resume, ASP system will restart the wind turbine again
