摘　　要：采用粒子群优化算法(particle swarm optimization,PSO)和菌群优化算法(bacterial foraging optimization,BFO)相结合的、带有随机惯性因子和异步时变学习因子的改进型BFO-PSO优化算法,解决混合型有源滤波器中无源滤波器参数优化设计问题。通过将滤波器的无功补偿容量、补偿后滤波效果及初期投资成本作为优化目标,采用重要目标加动态常数制约法给出综合适应度函数,进而求解多目标优化问题。仿真验证了理论分析和设计的正确性,相关设计方法也可为其他类型的无源滤波器的优化设计提供借鉴。With combination of particle swarm optimization algorithm and bacterial foraging optimization,an improved BFO-PSO optimized algorithm based on the random inertia factor and asynchronous time-dependent learning factor is used to solve optimal design,s problems of passive filter parameters for hybrid active filter.It takes the capacity of reactive power compensation,the harmonic effect after compensation and the original investment cost as three objectives,and restricts the important goal and dynamic constants as a method to achieve comprehensive fitness function,and then solves the multi-objective optimization problem.Simulation result verifies the correctness of the mentioned theory and design.Such design method can be used as a reference for design optimization of other type passive power filters.
