running pss/e from the dos command could also give you an insight of why it is crashing, also 35 now has a new tool called VERBDEB Option which could point you to the model which is potentially causing a crash.

You can also run psse from the dos windows, sometimes it tells you there where can be the problem.

you can actually select all buses by CTRL-A, then right click and use create bus subsystem, then used Modify/Create COnfig files, select subsystem only (no mon or con) , give it a name to you new subsystem with all the buses, click OK, and when edit your sub file and you will see all the buses of the slider on the new subsystem with the name you gave it before. Funny, if you ask Siemens they do not do this can be done. so maybe it is a bug, do not report it, it is very useful. R

Read POM Section 6, if you are referring to Static Synchronous Series Compensator.

DSTATE is the derivate of the state variable, PSS/E looks at it during initialization to check if it is zero (in steady state the state variable is a constant).

thank you. I did not know of ImageMagick. I was trying to do it first with Python but when executing the two lines illustrated above I get nothing, not even an error message, may be it is something very small that I am overlooking (with google I found very similar codes that seems to work)

Thank you. I used Distiller in a previous job but as far as I know it has been discontinued more than 10 years ago. I was looking for the option in which I do not need to be extra for software I rarely use. do you know where to get distiller from? thanks in advance

Thank you. I used Distiller in a previous job but as far as I know it has been discontinued more than 10 years ago. I was looking for the option in which I do not need to be extra for software I rarely use. if I look into download distiller in Adobe I find some in other languages, not English. unless I am looking in the wrong place I do not think this is a solution anymore unless you buy Adobe, is that right? please let me know if I am mistaken or if there is a server from where it can still be downloaded. thanks in advance.

When plotting dynamic simulations I prefer to generate ps type of files (like the resolution).did anyone find an easy way to convert *.ps to a *.pdf file? I tried using os and ps2pdf but it does no work, it does not give any error message but also does not create the pdf file.
the code could not be simpler.

import os os.system ('ps2pdf dynamicplot.ps dynamicplot.pdf')

as a rule of thumb; if you do not find an API in the manual, try executing PSS/E to obtain what you want and record what you are doing using *py. If you were to do this you will notice that you have two choices:

psspy.inta(number,number) psspy.area_zone(number,number)

where if number, number is 0,1 the report is for all areas

PSS/e does not have any API to do coherency-based equivalencing. The most you can do is to construct a short circuit equivalent to reduce the network.

yes, you are right. There is no way around the dummy bus. I hope that with the introduction of Node-Breaker capability it can be extended for use in dynamics. thanks.

Step 3 cannot be done using what is available in PSSE as "Dynamics/ Apply Disturbance". The goal was to use "apply unbalance fault at Bus..." so it can be automated. PSSE adds a dummy Bus. PSSE adds a dummy Bus but it is not available to the user (cannot trip B to dummy)

in a dynamic simulation: Is there any way that you can apply a SLG found in one end, open the same end at 6 cycles, fault still on and open the other end of the line at a delayed clearing time of 9 cycles? then clear the fault by opening the line. the question is how to do it, without the use of a user-created dummy bus; but rather what is available in PSSE calculating the fault with the short circuit module. thanks in advance

The Manual contains a lot of information, but it is not meant to be "a step by step", user-friendly type of thing. trust me, I have worked for PTI and used PSS/E since 1997. If you are just starting, go to a university such as Colorado State and take a look of the Introduction to PSS/E. Then you can formulate the right question and go to the manual for answers. Hope it helps.
