Abstract
A method of validating a wind turbine including a rotor includes intentionally inducing a loading imbalance to the rotor. The method also includes measuring the loading imbalance induced to the rotor, transmitting a signal representative of the measured loading imbalance to a calibration module, and at least one of detecting an error and calibrating at least one component of the wind turbine based on the signal.

A method of validating a wind turbine including a rotor, said method comprising:
- intentionally inducing a loading imbalance to the rotor;
- measuring the loading imbalance induced to the rotor;
- transmitting a signal representative of the measured loading imbalance to a calibration module;
- analyzing the signal by performing a frequency decomposition on the signal to calculate at least one of a magnitude of the loading imbalance and a phase of the loading imbalance;
- and,
- at least one of detecting an error and calibrating at least one component of the wind turbine based on the signal.
A wind turbine, comprising:
- a rotor comprising at least two rotor blades;
- and,
- a load control system configured to adjust a pitch angle of at least one rotor blade of said two rotor blades, said load control system further configured to:
- intentionally induce a loading imbalance to said rotor;
- measure the loading imbalance induced to said rotor;
- transmit a signal representative of the measured loading imbalance to a calibration module;
- perform a frequency decomposition on the signal to calculate at least one of a magnitude of the loading imbalance and a phase of the loading imbalance;
- and
- at least one of detect an error and calibrate at least one component of said wind turbine based on the signal.
A load control system for a wind turbine that includes a rotor, said load control system configured to intentionally induce a loading imbalance to the rotor, said load control system comprising:
- at least one sensor configured to measure the loading imbalance within the rotor and to generate a signal representative of the measured loading imbalance;
- and,
- a calibration module configured to:
- receive the signal;
- perform a frequency decomposition on the signal to calculate at least one of a magnitude of the loading imbalance and a phase of the loading imbalance;
- and,
- at least one of detect an error and calibrate at least one component of the wind turbine based on the signal.
