Load Calculation and Performance Analysis of Mega-MW Wind Turbine Based on Cloud Edge Computing

With the continuous development of megawatt-scale wind turbines, the impact of bladevibration on the dynamic stability and vibration of wind turbines cannot be ignored. However,there is currently no method capable of effectively analyzing the load and performance ofwind turbines. In order to improve the load calculation accuracy and performance of windturbines, this paper selects small base stations (SBS) as the research object of cloud edgecomputing, and explores the load analysis and performance analysis of megawatt-scale windturbines. In this paper, wind shear model, turbulence model, blade icing model andaerodynamic model of blades under icing conditions are established, and the effect of icing onthe dynamic load of blades of megawatt wind turbines is explored. It was found that the icinghad the greatest effect on the load in the direction of the blade array, followed by the load inthe swing direction, and the least in the torsional direction. In this paper, a load analysis isperformed on the blades of a megawatt wind turbine. When the blade speed increases, thefirst-order modal frequency deviation coefficient changes from -1.28% to 52.09%, and thethird-order modal frequency deviation coefficient changes from -0.77% to 48.67%. The speedof the wind wheel has a great influence on the first and third-order vibration frequencies of theblades of the wind turbine, but it does not have a great influence on the vibration frequenciesof the other steps.
