Abstract
Method, system, and computer readable medium for determining a fault in a power filter of a wind turbine generator. The method may include the steps of calculating a reactive power consumed by the power filter, and comparing the calculated reactive power to a predefined threshold reactive power to determine the fault.
Claims16
A method for determining a fault in a power filter of a wind turbine generator, the method comprising:
- calculating, using a computer processor, a reactive power consumed by the power filter of the wind turbine generator during a transition from a pre-charge state to a run state of the wind turbine generator;
- and
- comparing the calculated reactive power to a predefined threshold reactive power to determine said fault.
A system for detecting a fault in a power filter of a wind turbine generator, the system comprising:
- a computer processor;
- and
- a plurality of sensors electrically connected to said wind turbine generator and said computer processor;
- wherein said computer processor is configured to:
- calculate, during a transition from a pre-charge state to a run state of the wind turbine generator, a reactive power consumed by the power filter based on data from said sensors;
- and
- compare the calculated reactive power to a predefined threshold reactive power to determine said fault.
A non-transitory computer readable medium containing computer instructions stored therein for causing a computer processor to determine program code for determining a fault in a power filter of a wind turbine generator, the computer instructions being configured to:
- calculate a reactive power consumed by the power filter of the wind turbine generator during a transition from a pre-charge state to a run state of the wind turbine generator;
- and
- compare the calculated reactive power to a predefined threshold reactive power to determine said fault.
