摘要
基于系统阻抗的依频特性,用matlab仿真中的PSB工具,通过对安装有串联电容补偿装置的电力系统进行次同步谐振问题的仿真研究,分析了系统的次同步谐振频率与串联电容补偿度、输电线路长度及串补安装位置的关系。通过简单的实例说明了,如何通过合理设计串联电容补偿度和安装位置来规避次同步谐振的发生。
Based on the system impedance in frequency characteristics,by means of Matlab simulation of the PSB tools,a simulation research on sub-synchronous resonance in electric power system which installed series capacitor compensation devices is conducted. The relationship of system＇s SSR frequency and series capacitor compensation degrees,transmission line length and series compensation installation location has been analyzed. By means of the simple example to illustrate how to through the reasonable design the series capacitor＇s compensation degrees and installation location to circumvent the occurrence of SSR.
