摘　　要：阐述了分布式静止同步串联补偿器(DSSC)的潮流控制原理及拓扑结构,仿真研究了DSSC感性、容性补偿模式下的特性。搭建DSSC小样机,实验验证了DSSC的潮流控制功能。针对Matlab已有模块的局限性,设计了研究柔性交流输出系统(FACTS)装置频域特性的新方法,在证明该方法有效的基础上研究了DSSC的次同步频率阻抗特性,结果表明DSSC电阻分量恒为正,其电抗为负,且绝对值随着频率的增大而增大。The paper summarizes topological structure and principle of distributed static synchronous series compen- sator（DSSC）, both capacitive compensation and inductive compensation is discussed by means of time domain simu- lation.An experimental system of DSSC is designed, verifying that DSSC has good function of power flow control, and experimental results is in accord with simulation.A new method is applied to research the frequency characteristics of FACTS device based on Matlab.The results show that in sub-synchronous frequencies range,the real part of DSSC is positive, while its imaginary part is negative and its value increases as frequency increases.
