A Control Chart Approach to Power System Line Outage Detection Under Transient Dynamics

Online transmission line outage detection over the entire network enables timely corrective action to be taken, which prevents a local event from cascading into large scale blackout. Line aims detect an as soon possible after it happened. Traditional methods either do not consider transient dynamics following or require full Phasor Measurement Unit (PMU) deployment. Using voltage phase angle data collected limited number of PMUs, we propose real-time dynamic scheme based on alternating current (AC) power flow model and statistical change theory. The proposed method can capture system since retains time-variant nonlinear nature system. is computationally efficient scales realistic networks. Extensive simulation studies IEEE 39-bus 2383-bus systems demonstrated effectiveness method.
