Fractional-Order Time Delay-Considered Inertia Compensation Strategy Optimization for Wind Turbine Dynamic Simulation System

Abstract

The wind turbine dynamic simulation system enables the transfer of complex and challenging field tests to a controlled laboratory environment, making it widely applicable for wind turbine equipment testing and wind power strategy validation. However, when simulating real wind turbines, the system requires inertia compensation. During the execution of command reception and dispatch, the system is affected by fractional-order time delay, leading to an acceleration deviation component in the dynamic simulation process and resulting in speed fluctuation issues. To address this problem, this paper proposes an inertia compensation strategy for the wind turbine dynamic simulation system based on fractional-order time delay deviation suppression. First, a mathematical model of the wind turbine dynamic simulation system is established to analyze the existing acceleration deviation component and abnormal speed fluctuation in conventional inertia compensation strategies. Second, a deviation suppressor is designed based on the zero-pole placement principle. Finally, the stability of the system with the suppressor is verified, and a simulation model is constructed to demonstrate the effectiveness of the proposed method
