You should show the error message!!!!

Both case and bus_chng_3 are returning error codes. Print those codes for debugging.

Your arguments to API buschng3 are completely wrong. Use the defaults _i, _f, _s instead of zeroes.

EDIT:

In scripts you may need to import the defaults with the following:

import psspy
_i = psspy.getdefaultint()
_f = psspy.getdefaultreal()
_s = psspy.getdefaultchar()

I used defaults _i in some of programs and it wrong. so i fix them to Zeros and it can run finely

No, it is completely wrong to insert zeros instead of _i! This is the reason why you have the errors above. Just follow the rulebook. You can never use zeros for default values. For example, you force the area number to 0 which is an illegal number.
