【 摘 要 】

Problem statement: The inter-area power systems have special characteristic of thestability behavior. The improvement of inter-area power system is one of the important aspects inpower system. Approach: This study applies the Static Synchronous Series Compensator (SSSC) toimprove stability of inter-area systems. The SSSC is modeled and then is applied to be incorporatedinto the power system model for investigating stability improvement. The SSSC is modeled as thevariable susceptance and is controlled during dynamic state. This presented SSSC model can beincorporated into susceptance matrix of power system model. The presented method is tested onsample inter-area power system with 3 phase fault distubrances. Results: The swing curve of inter-areapower system without a SSSC gets increases monotonically and thus the system can be considered asunstable whereas the swing curves of system with a SSSC can be considered as stable. Conclusion:From the simulation results, the SSSC can enhance stability of inter-area power systems.
