MONITORING SYSTEM AND A MONITORING METHOD FOR A WIND TURBINE GENERATOR

摘要

A monitoring system for a wind turbine generator comprises: a wind speed obtaining unit for obtaining a wind speed; a wind condition identifying unit for identifying a wind condition parameter which includes at least one of a wind shear or an upflow angle of a wind which acts on a rotor of the wind turbine generator based on the wind speed obtained by the wind speed obtaining unit and at least one of a power output or a pitch angle of the wind turbine generator measured upon occurrence of the wind speed; and a fatigue load calculating unit for calculating a fatigue load of a component of the wind turbine generator based on at least the wind condition parameter identified by the wind condition identifying unit and a wind turbulence intensity of the wind which acts on the rotor.
