Did you know?
The critical clearing time defines the maximum time a disturbance (here a 3-phase-fault) can be applied without the power system losing its stability. In other words, if you remove a 3-phase-fault before reaching the critical clearing time, the power system will remain stable. If you remove the fault after the … See more For the demonstration, I use the good old 39-bus New England system as shown below.
