Method, device and product for response analysis of offshore wind turbine considering uncertainty of wind profile

Abstract

The present disclosure provides a method, device and product for offshore wind turbine response analysis considering wind profile uncertainty, and relates to the technical field of computers. The method for offshore wind turbine response analysis considering wind profile uncertainty comprises: obtaining wind observation data; comparing the goodness of fit of a plurality of candidate wind profile models based on the wind observation data to determine a target wind profile model; performing parameter fitting on the wind observation data based on the target wind profile model to determine the probability distribution of model parameters; determining the joint probability distribution of wind field variables based on the probability distribution of model parameters and the probability distribution of basic random variables; obtaining the basic random variables by reducing the dimension of the random variables required for simulation of the spectral representation method; determining the target sample points and corresponding weights based on the joint probability distribution of wind field variables; performing dynamic response analysis on the offshore wind turbine according to the target sample points to obtain structural responses; and calculating the statistical moments of the structural responses according to the structural responses and the corresponding weights for response analysis.
