2023-09-25 04:26:05 -0500 | commented answer | Example deadband in Fortran Code Thank you very much Dr Perolofl, Dr Perolofl, I have a question.do you have an example transformation dq frame to alpha-beta and then connected to current injection method in psse? I was made dq frame to alpha-beta but after fault it seems the value of alpha-beta conversion will diverge after fault |

2023-03-14 04:24:28 -0500 | commented question | Asking Fortran for Machine Trip Dear Dr Perolofl, trip message is appeared, but the main problem, simulation is stop after trip is applied. example the trip at 2.1 s so the graph only shows until 2.1 s too. However the total simulation that we want more than this value. |

2023-03-09 08:37:43 -0500 | asked a question | Obtain iteration of time step value in fortran hello everyone, I want to get value of DELT (time step) in fortran, however using CALL DSRVAL('DELT', INDX, RVAL, IERR) has a problem. main purpose is simple, just want to use this function as a record time at certain condition example [The plus-equals operator in python (+=) which provides a convenient way to add a value to an existing variable and assign the new value back to the same variable] --> i += DELT -->if i > a: ------>certain condition is there any other way to simulate this condition using FORTRAN? |
