英文摘要：

In order to carry out the analog study of the fan inverter in the laboratory, a dynamic wind turbine simulator based on the doubly-fed generator was designed, a novel dynamic torque compensation scheme was developed in the generator side, and the whole of a doubly-fed wind power generation system driving simulation platform was constructed. Carrying on the quantitative analysis and simulation of wind shear effects and tower shadow effects of wind turbines, the influence of the third harmonic torque ripple caused by wind shear effects and tower shadow effects on the doubly-fed wind power generation system was studied in detail. A control strategy of torque ripple suppression on the generator side was put forward. The simulation and experimental results proved the effectiveness and feasibility of the control strategy.
