摘　　要：无源电力滤波器(Passive Power Filter,PPF)以其高性价比在电力系统中得到了广泛的应用。用不同阻抗频率特性的PPF拓扑支路组成无源滤波网络是目前无源滤波的通用方法,实际中PPF支路拓扑设计通常依靠设计者的工程经验,缺少系统的设计方法,更谈不上对支路拓扑的优化设计。本研究提出了一种基于粒子群优化算法(Particle Swarm Optimization,PSO)的PPF支路拓扑的优化设计方法,解决了工程设计中单纯依靠工程经验设计PPF支路拓扑的盲目性问题。本方法首先基于PSO优化了各种滤波支路中补偿容量的分配,然后以总投资成本、单调谐滤波支路平均品质因数及电流谐波平均含有率为目标函数优化出最佳PPF滤波支路网络。并以一个实际的工况为例,验证了优化设计效果。In power system,Passive Power Filter（PPF）is widely used because of its advantage in performance-price ratio.Currently,it is a common solution of harmonic suppression to use passive filter network composed by PPF branch topologies with different impedance-frequency characteristics.In this solution,topology design of PPF network usually depends on engineering practical experience of PPF designer,there has a gap in the systematic design method,let along optimal design of branch topologies.This paper presents an optimization design method of PPF branch topologies based on PSO,and this method solves the problem that PPF branch topologies are blindly selected only relying on engineering experience.The method firstly optimizes the allocation of reactive power compensation capacity of each branch based on PSO.Then,total investment cost,average quality factor of all single-tuned filter branch and average harmonic current ratio are used as the objective function,PPF filter network is optimally obtained.Finally,the optimal effect has been verified by an actual work condition of power system.
