Wind Turbine Generator Transmission Chain Load-considering Model Predictive Control Frequency Regulation Strategy
摘要
Abstract
To mitigate the fatigue load generated by wind turbine participation in primary frequency regulation,a primary frequency regulation strategy considering the fatigue load of wind turbine was proposed based on the mechanical dynamic response characteristics and control device operation characteristics of wind turbine under different wind speeds.Firstly,based on the dynamic response characteristics and primary frequency regulation control device operation characteristics of grid-connected wind turbine,the fatigue load model of wind turbine was derived.Secondly,by constructing the state space model of wind turbine,the primary frequency regulation and fatigue load of wind turbine were transformed into a multi-constraint multi-objective optimization mathematical model.Based on the model predictive control(MPC),the dynamic frequency deviation was reduced while the fatigue load of wind turbine was lowered.Finally,based on the Matlab/Simulink platform,the frequency regulation capability and fatigue load of wind turbine under different control strategies were compared through time-domain simulation and analysis.The results show that the proposed control strategy is more effective than the existing control strategy in improving the frequency response capability of wind turbine and reducing the fatigue load of wind turbine,thereby extending the service life of wind turbine.关键词
