Title:
METHOD AND DEVICE FOR DETECTING EQUIVALENT LOAD OF WIND TURBINE GENERATOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/103286
Kind Code:
A1
Abstract:
Provided are a method and device for detecting an equivalent load of a wind turbine generator system. The method comprises: within each detection period, detecting environment data of each wind turbine generator system in a wind farm (S110); within each detection period, detecting loads of one or more correction wind turbine generator systems of the plurality of wind turbine generator systems, and using the detected loads to calculate equivalent loads of the correction wind turbine generator systems (S120); and based on the detected environment data of each wind turbine generator system, using a load estimation model to determine an equivalent load of each wind turbine generator system (S130), wherein the load estimation model indicates a relationship between the environment data and the equivalent loads of the wind turbine generator systems, and before using the load estimation model within each detection period, equivalent loads calculated within a current detection period and equivalent loads, determined through the load estimation model within a prior detection period, of the correction wind turbine generator systems are used to correct parameters of the load estimation model.
