摘　　要：针对电压暂降问题,串联型和并联型动态电压恢复器DVR是目前最为成熟的两种装置。本文提出了一种同时计及串/并联型两种形式的配电网DVR组合优化配置方法,通过综合考虑不同类型DVR的特点进行容量选择,提高了配置方案的经济性和灵活性。首先,根据串联型DVR和并联型DVR的工作原理,分析两种补偿装置的配置需求,以满足敏感负荷正常运行为前提,建立以总投资成本最小为目标的配电网DVR组合优化配置模型;其次,利用改进的粒子群算法,对优化配置模型进行求解,获得最优DVR配置方案;最后,以某用户供配电系统为实例,验证了所提串/并联型DVR组合优化配置方案的经济性和可行性。In view of voltage sag,both series and parallel dynamic voltage restorers(DVRs)are presently the most mature devices.In this paper,a kind of the collaborative optimal configuration scheme of DVR of distribution network considering both series and parallel is proposed,the capacity selection is performed through comprehensively by considering the characteristic of different types of DVR,thus improving both economic performance and flexibility of the scheme.Firstly,the configuration requirement of the two devices are analyzed respectively in accordance with the operating principle of the serial and parallel DVR so to,with meeting the normal operation of the sensitive load as the premise,set up collaborative optimal configuration model of DVR of distribution network with the minimum total investment cost as the target.Then,an improved particle swarm optimization algorithm is used to solve the optimal configuration model so to obtain the optimal configuration scheme for DVR.Finally,the power supply system of a certain customer is taken as the real example,the economic performance and feasibility of the proposed series/parallel DVR collaborative optimal configuration scheme is verified.
