Hello, i am sorry, i can't answer your question, i am also newbie in UDM, do you know how to calculate P and Q measure in UDM?

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

Hello again Dr Jconto, do you have an example fortran code from dq to alpha beta transfrormation for simple basic PI converter?

Is there any fortran code to monitoring frequency value? BSFREQ(IS) not working in my case

Dear Dr Perolofl, i tried using DELT function but it seems (DELT is not iterated just a fixed value) is there any Fortran code for time step iteration (example 0.00025, 0.00050, 0.00075)

yes Dr Perolofl, for now I use GENTRP. Actually, when I see API documentation, API for Machine trip only this code (DISTMACHINETRIPAPI). Thank you very much Dr Perolofl

Dear Dr Perolofl, it is work normal using GENTRP(IBUS, ID) howeever, this function does not include in API, is there any other way to search documentation for another "hidden" API such as GENTRP?

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.

CALL DISTMACHINETRIPAPI(IBUS, ID, IERR) dear everyone, after I put this in Mode 3, for certain condition (If function), simulation system will not converged. is there any other api for fortran to call this function? thank you very much

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?

2023-03-09 07:19:07 -0500 commented answer How to obtain and hold the value of STATE/VAR at a certain time?

hello Dr Perolofl and Dr Dat, sorry for jump in. may I ask something, after put this code in Fortran VM = Voltage measurement = VAR (L) VRT = CON (J) = Example (0.8) IF(VM.LE.VRT) THEN VAR(L+1) = TIME when I check output of voltage, voltage is decrease, but there is no recording time after fault

Dear Dr Perolofl, I found that problem, in ver 33.5 the plot tree doesn't automatically appear. So, we need setting "Plot tree" in menu bar. After that, we can see a channel output problem.

Hello there, the output of PLNTBU1 will go to REAX4BU1 Controller. In addition you can also modify the the value kw1 &kp1 similar with (1%-5%) droop on rating capacity concept

Hello everyone,

Currently I have problem to plot output file, I already make sure to create channel and cross-check with ver 33. in ver 33, the out file could be described. On the other hand in ver 35, I can't see a result. Do you guys have a solution for this problem?

Thank you
