Thank you but it does not work. Now it says that this property is a float, so I tried to convert to string but it does not work. AttributeError: 'float' object has no attribute 'realari'

Hello;

I did a program which increases a TAPs position in an OLTC transformer. However, when I want to see the tap position I have an Error. Someone knows how could I obtain the TAP position with print command? or maybe I need to use another, What do you think?

Set the TAP position

TAP=1.000+Tap_pos
ierr, TRF = psspy.two_winding_data_6(ibus_trafo, jbus_trafo, '1', realari4=TAP)

For obtaining the value I used the next command:

print("TAP = " TRF.realari[3])
print("TAP = " TRF.realari4)

I obtained the next error message depending on the print used:

AttributeError: 'tuple' object has no attribute 'realari'
attributeError: tuple object has no attribute 'realari4'

I am writing because I am testing a Wind Farm with 2 aggregated branches. In each branch, I have a different number of WTGs. I would like to do a P set point test with the Plant controller in the PCC. For that issue, I designed the 2 aggregated WF with a second-generation WECC Model according to the type 3 model described in the model library and for the PLANT Controller, I used the PLANBU1 + 2 auxiliary model REAX3BU1 for representing each WT branch. For checking any bug in the WF Controller model I did a Qstep test, PFstep and V steps and I obtained a suitable response of each study. However, when I did the Pstep study I have not any response at the WECC PI. The PI active Power is not reacting, it is equal 0. Also, the l REAX3BU1 has not seen the P set point. Does someone know if P test study performed by PLNTBU1 + Auxiliary control work with 2 aggregated branches work? Are These library models work in PSSe 33 and 34?

Finally, the problem was in the definition of the .out file, I will write the solution. Thank you!!

I followed your advice, but now PSSe told me --> Error - Reading channel data error. I re-made the code in the post, but I PSSe does not achieve to read the out_file. Do you know what could it is happen?

Hello, I am writing because I have around 50 .out files. Inside each simulation, I have several channels. I would like to export all of them into an excel file or a txt. I tried to export with a function named " dyntools" and also with "excelpy" but it does not work. Someone knows, How could create an excel file? Could I create a TXT instead and EXCEL file with all the channels info to avoid the overflow error? Could I do a txt file with all the channels without created a graph in python?

    import excelpy
    import dyntools

# LF process

# Channels identification

#LVRT TEST: out_file11

#PROBLEM: EXPORT ALL OUT CHANNELS TO AN EXCEL/TXT FILE

According to the information which I read in the forum, I did several tests in order to find the best way for exporting the .out channels to and text or excel file. However, I have not any psse reply, The excel is not created and no answer is written in the alert/progress output file. After doing several tests, the problem was in the definition of the Output file it was fixed thanks to the post "Using api "pssplot.channelfileexcelexport()" rasise error" , I write the solution and the tests which I did:

SOLUTION*

In the dynamic simulation test the .out should be defined:

psspy.set_chnfil_type(0)  
psspy.strt_2([0,1],out_file11)
psspy.run(0,3.0,L1,L2,L3)

Hi!

I try to obtain the plant total power output from the Bus WF

CMPVAL2 =psspy.gendat(Bus_WF)
psspy.progress('  REAL_SCMPVAL  ' +str(CMPVAL2[1].real)+'\n')
psspy.progress('  IMA_SCMPVAL  ' +str(CMPVAL2[1].imag)+'\n')

I have the following error AttributeError: 'NoneType' object has no attribute 'real'

Also, I created a variable for keeping the REAL_MW = CMPVAL2[1].real but I received the same error.

I don´t know what is happening, Somebody can help me?

Thank you a lot!
