System and method for monitoring power filters and detecting power filter failure in a wind turbine electrical generator

摘要

SYSTEM AND METHOD FOR MONITORING POWER FILTERS AND DETECTING POWER FILTER FAILURE IN A WIND TURBINE ELECTRICAL GENERATOR A method for determining a fault in a power filter of a wind turbine generator, the method including 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. A system for detecting a fault in a power filter 10 of a wind turbine generator, and a computer readable medium containing computer program code for determining a fault in a power filter of a wind turbine generator are also disclosed.
