Power system learning / Adaptive Defense Scheme
Adaptive Defense Scheme Explained: Trip Matrix, OLS, OGS and Islanding Logic
An Adaptive Defense Scheme watches system conditions and chooses corrective actions based on topology, loading, generation, island status, and operational constraints. It is not only a fixed trip list; it should understand the current network state.
What makes it adaptive
The same contingency can require different actions depending on which busbar is energized, which generators are running, and whether the area is grid-connected or islanded.
Trip matrix reasoning
The simulator previews candidate trips and explains the need, target, and reasoning so learners can see why a feeder, generator, or interconnector action was selected.
Where it helps
Adaptive logic is useful for overload shedding, over-generation shedding, islanded operation, blackstart restoration, and preventing cascading outage scenarios.
