摘　　要：为提高机场行李处理系统运行的稳定性,避免系统谐波对机场电网造成干扰,利用有源电力滤波器,设计了机场行李处理系统谐波抑制方法。首先,对机场行李处理系统谐波作出评估,准确了解机场行李处理系统电力供应系统中谐波的分布情况、含量以及对系统的影响。其次,进行有源电力滤波器选型与安装,为谐波抑制奠定良好的基础。最后,设计谐波抑制方案,通过自适应调整与PWM调制,实现谐波有效抑制的目标。实验结果表明,提出的方法应用后,系统谐波畸变率显著降低,最高不超过0.5%,减小了谐波对机场电网和设备的不良影响,提高了系统的稳定性和可靠性。In order to improve the stability of airport baggage handling system and avoid the interference of system harmonics to airport power grid,an active power filter was used to design a harmonic suppression method for airport baggage handling system.Firstly,the harmonics of the airport baggage handling system are evaluated to accurately understand the distribution and content of harmonics in the power supply system of the airport baggage handling system and their impact on the system.Secondly,the selection and installation of active power filters lay a good foundation for harmonic suppression.Finally,the harmonic suppression scheme is designed to achieve effective suppression of harmonics through adaptive adjustment and PWM modulation.The experimental results show that after the application of the proposed method,the harmonic distortion rate of the system is significantly reduced,the highest is less than 0.5%,which reduces the adverse influence of harmonics on the airport power grid and equipment,and improves the stability and reliability of the system.
