An application example for on-line DSA systems

A Transient Stability Analysis & Control (TSA&C) system has been developed and installed at PJM Interconnection several years ago, to perform on-line Dynamic Security Assessment (DSA) for the PJM power system. TSA&C was successfully applied to investigate an event that took place recently in the PJM system. This paper presents this application example to illustrate value and benefit of an on-line DSA system in the investigation of real-world events.
