Abstract

A method and system for detecting asymmetric utilizing longitudinal tower acceleration data may include: providing a rotorspeed acceleration monitoring system; determining from the rotorspeed acceleration monitoring system whether a rotorspeed acceleration is above a rotorspeed acceleration limit; determining whether a rotor-mass imbalance condition exists; and determining whether a longitudinal tower acceleration coincides with icing on a rotor.
