I am trying to test frequency ride through in PSSE for 0.3Hz step/down from 60 Hz. My PLBVFU1 model looks like "260 'USRMDL' 1 'PLBVFU1' 1 1 3 4 3 6 1 1 'BA3PlayRT' 1.0 60.0 0.00 0.00 /" in dyr file, also my plb file is @!time, V(kV), f(Hz) @!6.5 TO 6.8 FAULT 0.0 1.0 60.0 6.5 1.0 60.0 6.5001 1.0 60.3 6.8 1.0 60.3 6.8001 1.0 60.3
12.0 1.0 60.0.

When I plot them in PSSE, I don't see frequency from 60 Hz to 60.3 Hz, instead plot starts from 1 goes to 0.005 and back to 1.

Can anyone help is finding the issue, also how can I plot 60 Hz data in PSSE. Am testing these models against PSCAD where frequency is in 60 Hz. Because of this difference, I can't plot both the PSSE and PSCAD values on same plot for MQT's.

in dyr file, also my plb file is
