1. the method (200) of the asymmetric accumulated ice on the detection wind turbine (100), said method comprises:

  • Spinner velocity acceleration monitoring system (180) is provided;

    Confirm that from said spinner velocity acceleration monitoring system (180) the spinner velocity acceleration is whether on the spinner velocity acceleration limiting (275);

    Confirm that from said spinner velocity acceleration monitoring system (180) said spinner velocity acceleration is whether with the frequency relevant with spinner velocity fluctuate (223);

    Determine whether to exist rotor quality unbalance condition (255);

    Confirm said rotor quality imbalance whether conform to (260) with epitrochanterian accumulated ice;

    AndConfirm vertical tower acceleration whether conform to (270) with epitrochanterian accumulated ice.
