摘　　要：近年来,电力电子设备在电力系统中的广泛应用导致了大量超高次谐波的产生,从而造成了一系列电能质量问题。为有效抑制超高次谐波,本文提出一种基于改进鱼鹰优化算法(IOOA)的超高次谐波无源滤波技术。首先,使用无源阻尼的LCL和陷波拓扑结构,以增强对高频谐波的抑制效果。其次,针对该拓扑结构,提出离散系统控制方法与稳定判据。然后,对传统鱼鹰优化算法进行改进,提出基于IOOA的无源电力滤波器(PPF)参数优化模型,综合考虑系统稳定性、无源阻尼设计和成本费用等因素,进行参数优化以提高超高次谐波的抑制效果。最后,通过光伏逆变器进行仿真和实验验证。结果表明,所提出的方案能在保证系统稳定性的基础上,有效抑制低次谐波和超高次谐波,使总需求畸变率低于3,从而最终验证了所提方法的实用性和有效性。In recent years,the widespread application of power electronic equipment in the power system has led to the generation of a large number of supraharmonics,resulting in a series of power quality problems.To effectively sup-press supraharmonics,a passive filtering technology for supraharmonics is proposed based on the improved osprey op-timization algorithm(IOOA).Firstly,passive damping LCL and notch topology are used to enhance the suppression ef-fect on high-frequency harmonics.Secondly,a discrete system control method and stability criterion are proposed for this topology structure.Then,the traditional osprey optimization algorithm is improved,and a PPF parameter optimiza-tion model based on 10OA is proposed.Taking into account factors such as syslem stability,passive damping design,and cost,parameter optimization is carried out to improve the suppression effect of supraharmonics.Finally,simulation and experimental verification are conducted using a photovoltaic inverter.The results show that the proposed scheme can effectively suppress low order harmonics and supraharmonics while ensuring system stability,resulting in a total demand distortion rate below 3,ultimately verifying the practicality and effectiveness of the proposed method.
