摘　　要：设计了一套分布式潮流控制器装置参数设计方法,由线路潮流变化范围确定串并联侧变流器的容量,按分布式潮流控制器的功率模型和功率守恒原理,确定串联侧注入输电线路的最大基频电压幅值、流过串联侧变流器的电流以及并联侧变流器向系统注入的电流和电压,再根据逆变器输入输出电压的关系确定直流电容电压和变流器的开关参数.最后验证参数设计方法的正确性,使用PSCAD/EMTDC仿真软件搭建了一套分布式潮流控制器接入10kVA输电系统进行仿真实验,显示DPFC能快速有效改善系统的电压和潮流的能力,证明本文的装置参数设计方法的正确性.In this paper,a method is presented for parameters setting of the distributed power flow controller（DPFC）.First,the capacity of parallel and cascade-side converters was determined based on line power flow range.The maximal voltage amplitude of the fundamental frequency for the parallel-side transmission line,the current which flows through parallel-side converters,and the current and voltage injected from cascade-side converters to the system were calculated according to the power model of distributed power flow controller and the principle of conservation of power.Then,DC capacitor voltage and parameters of the converter switch were determined by using the relationship between inverters＇ input voltage and output voltage.Finally,simulation test was conducted by connecting 10 kVA transmission system and the distributed power flow controller built with PSCAD/EMTDC simulation software.The results show that DPFC effectively improves the system in terms of power and power flow,and thus the correctness of the proposed method is demonstrated.
