Monitoring and Alarm System Timing Analysis for an Interconnecting Grid

Power system oscillation is a common problem in interconnected power grids. Progress has been made in measurement-based oscillation analysis due to the increased utilization of wide-area measurement system (WAMS). However, robust solution set approaches, such as oscillation classification at the “edge” and dynamic re-tuning of power system stabilizers (PSS), are often not exercised; rather generation shedding has become a common approach vector. This interim approach has risen in prevalence while the actual engineering to address root causes has been sidelined; this paper delineates the issue and posits a prospective solution for the current timing problem.
