摘要

针对柔性交流输电(FACTS)领域中的一种新装置——分布式静止同步串联补偿器(DSSC)

在实现其潮流调节功能的基础上

首次从频域的角度研究了DSSC特性

得到了DSSC的频率-阻抗分布曲线

既为DSSC影响次同步谐振的机理研究提供了理论依据

也为其他FACTS装置的研究提供了新的思路.进一步

采用测试信号法

研究了DSSC对一个串联电容补偿系统的电气阻尼特性的影响

结果表明

DSSC的串入使得系统的谐振点频率发生偏移

电气负阻尼绝对值显著减小

证明DSSC对于次同步谐振具有抑制作用.

Abstract

A new type of flexible AC transmission system(FACTS)devices-distributed static synchronous series compensator(DSSC)

which enables to realize grid power flow control

is proposed. The DSSC is investigated from the view point of frequency domain and the impedance characteristics of the DSSC in sub-synchronous frequencies range are analyzed to provide the theoretical support for the sub-synchronous resonance(SSR)mechanism research. By means of test signal detection

the IEEE second benchmark model(system 1)is adopted and the system SSR damping characteristics are revealed. The results show that the resonant point of the combined system is shifted and the electric negative damping around the resonant point is reduced greatly.
