I want to simulate a Slope in PSCAD with Block Diagrams, I know how to simulate the numerator, but the denominator that is DeltaT=t2-t1 for a Disturbance event of load step for example or Generator outage is somehow questionable for me. How can I simulate the DeltaT for 15 seconds in PSCAD/EMT software? Thanks a lot.
t1=The time when the system operates in steady state
t2=The time when the system operated in Transients(We have fault in our Grid)
