Linecode - Basefreq

[Anushi]

Hi,
I'm solving my script in 50Hz. Since I don't have impeadance matrix defined for 50Hz, Can I use the following linecode impeadance matrix that are defined in 60Hz. Thanks.

New linecode.601 nphases=3 BaseFreq=60
~ rmatrix = (0.3465 | 0.1560 0.3375 | 0.1580 0.1535 0.3414 )
~ xmatrix = (1.0179 | 0.5017 1.0478 | 0.4236 0.3849 1.0348 )
~ units=mi
New linecode.605 nphases=1 BaseFreq=60
~ rmatrix = (1.3292 )
~ xmatrix = (1.3475 )
~ units=mi

That should work.

Set DefaultBaseFrequency=50

Then when you define something that is not 50 Hz, specify the base frequency.

Let us know if it doesn't work.

I will. Thank you Mr. Dugan for the kind reply.

It didn't work. Eventhough I set the basefreq=60HZ in linecode, in line properties it showed 50Hz. And R and X matrics were different from the defined values. Can you please have a look at this snapshot? Thank you

Hello,

Sure, it makes sense. Move the "Set DefaultBaseFrequency=60" after the first "clear" command, just before declaring the "New Circuit..."

But I want to solve my script with default frequency =50Hz. What I'm saying is, eventhough I re-declare base freq=60Hz for linecode (Because I'm using impeadances defined at 60Hz) it still shows 50Hz in line_dump_property.
Is this acceptable or Should I need to define rmatrix and xmatrix in 50Hz? Thank you

Hello,

You need to be consistent. OpenDSS is a frequency domain simulation tool, so you will have to define everything at the same frequency.

Best regards

Thank you Mr. Montenegro for the reply.
