Revision history [back]

When making a pause in the simulation there will be double time values written to the out-file. The last time step before the pause is called t- and the first value after a pause is called t+. See Chapter 13.5.4 in Program Application Guide, Vol 2.

In your example the time step is 0.001 s, i.e. 1 ms. Starting with t = -0.002 the simulation is paused at times t=0.00244140625 and t=0.0048828125 s

The simulation runs up till the actual time is >= tpause.

The first run command to t=0.00244140625 will print the following time values to the channel file:

-0.002 t+
-0.001
0.000
0.001
0.002
0.003  t-

i.e., the simulation is paused at t=0.003 s.

The second run command to t=0.0048828125 s will print the following time values to the channel file:

0.003 t+
0.004
0.005 t-

i.e., the simulation is paused at t=0.005 s.

The last run command t=0.0.00732421875 will print the following time values to the channel file:

0.005 t+
0.006
0.007
0.008 t-

There is nothing wrong with your results, this is how PSSE works!

It shall be noted that the simulation will only be stopped at an simulation step. It is not possible to halt the simulation at t=0.0.00732421875 s.
