Method and System for Utilizing Rotorspeed Acceleration to Detect Asymmetric Icing

摘要

A method (200) and system (180) for detecting asymmetric utilizing longitudinal tower acceleration data may include: providing a rotorspeed acceleration monitoring system (180); determining from the rotorspeed acceleration monitoring system (180) 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.
