摘　　要：在非正弦和不平衡运行条件下,双馈感应发电机会面临显著的转矩脉动问题,严重威胁系统的安全稳定运行,因此有必要采取转矩脉动抑制措施。近些年,诸多学者针对该问题进行了广泛研究,并取得了一系列的科研成果,但鲜有对其进行总结归纳的文献。为此,该文首先介绍了双馈感应发电机系统结构,分析了非正弦和不平衡运行条件下转矩脉动成因,并明确了转矩脉动抑制的主要目标。其次,从硬件结构改进法和控制策略改进法两方面对现有技术方案进行归类总结,并从七个维度进行综合对比分析。最后,从软硬件协同抑制、参数鲁棒性提升、谐波损耗抑制和故障穿越四个方面对双馈感应发电机转矩脉动抑制方法的未来发展趋势进行了展望。Under non-sinusoidal and unbalanced operating conditions,the doubly fed induction generator(DFIG)encounters significant torque ripple issues,which can severely damage the gearbox and drive shaft and threaten the safety and stable operation of the system.In recent years,numerous solutions have been proposed.This paper classifies and summarizes the existing technical solutions,enabling scholars in related fields to quickly understand the research status and development trends,thereby promoting the further development of torque ripple suppression technology for DFIG.Existing technical solutions can be divided into hardware structure improvement and control strategy improvement methods.The hardware structure improvement method mainly includes using multi-pulse rectifiers,adding passive filters,and using voltage source converters.This method can effectively suppress torque ripple but requires changing the machine structure or adding additional equipment.As a result,the system cost is high,so the hardware structure improvement method is often used in the system design stage.The control strategy improvement method is the most commonly used,including the torque closed-loop control method,the torque open-loop control method,the non-ideal component elimination method,and the multi-objective predictive control method.The torque closed-loop control method can achieve high-precision torque control and has good system stability but its target extensibility is low,which is often used in applications requiring high torque quality.The torque open-loop control method has strong target extensibility and is often employed in systems with multiple control targets.However,the torque open-loop control method highly depends on machine parameters,and the parameter perturbation seriously affects the torque ripple suppression performance.The non-ideal component elimination method is relatively simple to control.However,it cannot simultaneously eliminate non-ideal components of voltage and current,and the effect of torque ripple suppression
