When the voltage drop amplitude is less than 0.9pu and the failure time lasts for 2s, the REECA1 model is removed (the in service button is automatically unchecked), and a circuit breaker is displayed at the output bar. However, I have not set any protection device in the network, may I ask if psse has its own protection device? If I want to modify it, where should I modify it？ Looking forward to your reply, thank you very much！
There is a call of miscellaneous model VTGTPAT in the snapshot. This is an under/over voltage generator bus disconnection relay.
See spreadsheet: Dynamics data - Other Models - Miscellaneous.
I see it！Thank you very much for your answer！

Is model REECA1 disabled automatically during the simulation? Please explain further: "a circuit breaker is displayed at the output bar".
When the voltage is lower than 0.9pu and the failure time lasts for 2s, the output bar displays: 'Breaker timer started at TIME =12.000 for Generator"1 "connected at bus 1[535.008]' (Fault occurs at 10s)
Look at the output of the curve and see that the output of REECA1 becomes 0, then go back to the sld file and see that the REECA1 model becomes a dashed line.
Do you mean that generator 1 at bus 1 is tripped?
Yes，at 12s, the generator 1 at bus 1 is tripped
