摘　　要：并联型有源电力滤波器(shunt active power filter,SAPF)多配置于非线性负载的并网点并对本地负载进行谐波电流补偿。随着配电网中非线性负载的广泛接入,导致基于本地补偿的配置方式不再具有经济、高效的优点,为了解决此问题,出现了以配电网整体多节点的电能质量为优化目标的综合补偿配置方案。基于此,本文提出了一种综合考虑配电网各节点电压谐波含量、SAPF总安装台数及安装容量的SAPF配置算法,结合多目标粒子群及单目标迭代算法确定在网络各节点谐波电压畸变率满足标准时SAPF的数量、配置节点及最优输出电流。最后,通过仿真搭建IEEE18节点标准模型,验证了所提出的算法在多台SAPF配置问题中的有效性。Shunt active power filter(SAPF for short)is mainly allocated at the grid connection point of nonlinear load and performs harmonic current compensation of local load.With the widespread access of non-linear load in the distribution network,the allocation method based on local compensation is no longer economic and cost-effective.For Solving this problem,the comprehensive compensation allocation scheme with that takes the overall multi-node power quality of the distribution network as the optimization goal has emerged.On this basis,a kind of SAPF allocation algorithm with comprehensive considering voltage harmonic content of each node of network,total installation number of SAPE and installation capacity is proposed in this paper.The number of SAPF,allocation node and optimal output current when the harmonic voltage distortion of each node of the network meets the standard requirement is defined with combination of multiobjective particle swarm optimization and single-objective iterative algorithm.Finally,the IEEE-18 node standard model is built by simulation and the effectiveness of the proposed algorithm in the allocation of multiple SAPF is verified.
