Hi, I am wrting user-defined model. And I want to make one variable delayed by some time over another variable. For example, DELT is 0.00005 and the delay time is 0.01. How to write time-delay? Thanks a lot.
A transport delay may be modelled by assigning a sufficient number of VARs to accomodate the delayed signal. The number for VARs needed will be at least dt/delt, where dt is the maximum allowed delay time and delt is the minimum used time step.
In your situation you need at least 200 VARs for the delayed signal. At each time step, the values in the VAR vector shall be advanced one step (if KPAUSE<>1).
I just wonder what is the reason for this extremely short time step of 0.05 ms????? PSSE is not designed for such short time steps.
