Now I create a SMIB to the solar inverter to test the inverter model. However, the voltage and current is very strange. As a result, I want check the model itself. Is there any method to get the Model VARS value curve during the Dynamic Simulation such as bus voltage?
Another question is, how can I get the bus frequency value in HZ? Thank you very much.
ierr, variableNumber = psspy.mdlind(busNumber, 'machine id', 'GEN', 'VAR')
psspy.var_channel([-1,variableNumber],"variableName")
Here the first command stores the first variable 'VAR' associated with GEN into the variable varname. The second command add the channel corresponding to the variable variableNumber. You can use this commands to get any variable associated with any components.
For instance, If you want to store the second variable then,
psspy.var_channel([-1,variableNumber+1],"anotherVariableName")
Hope this helps
Hello, I have a similar doubt, and I don't think it has been responded.
I wanted to know, via Python, which are the VARs for each model, so I can iterate it and plot them on demand. The idea is to define a function that returns the numbers of the VARs per model - similar to the info we can get with DOCU.
Thanks, Nuno
VAR: See Miscellaneous Quantity in Chapter 20.5 of GUI Users Guide.
Hz: See FUNC - Add Function in Chapter 22.3.
One way to get the frequency in HZ is to add a function in the plot tree in psse after opening the .out file. Type in the function 60*(1+A) or 50*. After adding the function, then you can assign the frequency deviation channel you have to the value of A and plot the full functio
using psspy: ierr = var_channel(status, ident) mentioned in section 4.2.4.4 in psse v33 API book
