Hello. we do the dynamic simulation following:
1. Generate a user-defined model file .dll. 2. Calculating the trend 3. Import the .dyr file 4. Initialization. 5. dynamic simulation My qusetion is: In the whole process above, how is the mode 1-8 executed? and What is the order? (MODE4 MODE1 MODE3 MODE2 MODE3 MODE2...) Why does the PSS/E do follow the order?

and how to use the WRITE(LPDEV,*)

Thank you.

The MODEs are described in Program Application Guide, Volume 2, Chapter 13.5. Only MODE 1-4 are called in a dynamic simulation.

@perolofl Thank you. the execution order of MODE1-4 is? and how to use the WRITE(LPDEV,*) "STATE1" xxx and how to use the WRITE(DBUF01, 107) STATE(K) CALL PROGRESS(DBUF01,1)?

From POM: "Any error or progress report messages written in MODEs one through four should be written to the FORTRAN unit number specified by the variable LPDEV" Unit DBUF01 is unknown to me. Where do you find those statements?

Mode 4-1-3-2 is called at STRT. Mode 3-2 during each time step of the simulation.

@perolofl Thank you. I learn the WRITE(DBUF01, 107) from a friend from Psspy.

I think DBUF01 is a character variable and the WRITE-statement is writing to the variable using the formatting in 107 FORMAT-statement.
