| 2014-03-07 11:18:49 -0500 | commented question | Under/Overvoltage relay @yfing, Thanks for you quick response. When you say each bus do you mean adding three more fictitious buses ? I recall we cannot add same relay more than one in same bus. |

| 2014-03-07 08:56:37 -0500 | asked a question | Under/Overvoltage relay Hi Everyone, I am trying to implement Over/Under voltage relay at a bus. The only relay model I can see is VTGDCAT/VTGTPAT in miscellaneous other models but the problem with these model is the breaker time should be same for upper and lower voltage threshold. My question is how to write a python code so that we can have different breaker time for different upper and lower threshold voltage as below ? V (pu) = 1.1, 1.05, 0.9, 0.7
time(s)= 1, 5, 3, 2 Thanks |

| 2014-03-05 09:05:11 -0500 | commented question | Finding a machine index and changing the array value @yfwing, No luck yet. Actually I tried using quote too. Below is what I tried ierr,ival= psspy.windmind(104,1,'WGEN','VAR') ^ SyntaxError: invalid syntax Python Exception raised! Any suggestions why I am getting this error. Thanks |
| 2014-03-04 15:54:09 -0500 | commented question | Finding a machine index and changing the array value jconto, thanks for joining on the issue. I tried using the syntax ierr,ival= psspy.windmind(104,1,WGEN,VAR) and there still is error poping up. It says invalid syntax. |
| 2014-03-04 11:55:44 -0500 | commented question | Finding a machine index and changing the array value yfwing, Appreciate your quick response. I tried using the below syntax on the command line input ierr,ival=windmind(104,1,WGEN,VAR),but I am seeing the following error Traceback (most recent call last): File "<string>", line 1, in <module> NameError: name 'windmind' not defined. |

I am new to python, can anybody explain how to find the index number and change the array values using python? Thanks Diz |

| 2014-02-20 14:21:22 -0500 | commented question | Changing VAR(L) during dynamic simulation thanks yfwing for your response. I am not sure how to call a user-defined model in conec.flx, is it just like below Subroutine conec C include 'common4.ins' C call PVEU1 C return where PVEU1 is the model. If above is correct, then how to enter the data file ? Any example if you have ? |
| 2014-02-20 09:08:34 -0500 | asked a question | Changing VAR(L) during dynamic simulation Hello everyone, Is it possible to input the time series value in VAR (L) in a model during dynamic simulation ? I am trying to do a manipulation where I want to have my reference VAR(1) value equal to the input value to make the error zero. It can be done manually but its a problem when you have large data. |

| 2013-11-05 17:09:24 -0500 | asked a question | Regarding photovoltaic system model in PSS/E 33.4 Hello every one, I am new PSS/E user. I am trying to connect the Photovoltaic (PV) system model for dynamic simulation in a distribution system bus but not able to fully understand the dynamic input data of PSS/E 33.4 version (PAGV2.pdf). In other words what each data represents ? Just wondering if anyone has tried to connect this generic PV model in the feeder. best regards |
