Research on Active Power Fluctuation Suppression of Hydraulic Wind Turbine Generator Systems for Optimized Offshore Wind Power Operation
摘要
Abstract
Offshore hydraulic wind turbines are subject to multi-source disturbances from wind,waves,and the power grid,which degrade power control performance.To address this issue,an intelligent anti-disturbance control strategy integrating radial basis function sliding mode control and disturbance-observer-based feedforward compensation is proposed.A nonlinear model of the hydraulic transmission and energy storage system is established to describe the strong coupling and time-varying characteristics of the system.Based on this model,a coordinated control architecture combining"anti-disturbance tracking on the main transmission side"and"fluctuation suppression on the energy storage side"is developed.On the main transmission side,a radial basis function neural network sliding mode controller is designed to adaptively compensate for system uncertainties and achieve accurate power tracking under aerodynamic torque fluctuations.On the energy storage side,a feedback linearization controller based on a nonlinear disturbance observer is introduced to estimate and compensate for grid-side disturbances in real time,thereby suppressing active power fluctuations.Simulation and semi-physical experimental results show that,compared with the dual-layer integral feedback linearization control strategy,the proposed strategy reduces the power tracking settling time to 0.01 s and limits the steady-state error to less than 2%.Under grid voltage sag conditions,the power overshoot is reduced by more than 50%,and the power deviation during fluctuation suppression remains within 0.02 kW.The proposed method provides an effective intelligent control solution for high-performance power regulation of offshore hydraulic wind turbines under complex marine operating conditions.关键词
