Ahh, I see thank you very much Mr Dugan. Much appreciated.

Hi there everyone, I’m hoping this isn’t a silly question but I’m executing the “LVTestCase” in both Yearly and Daily modes. The daily mode is giving me the following results: Total Active Power: 0.0589938 MW Total Reactive Power: 0.0194281 Mvar Total Active Losses: 0.000880338 MW, (1.492 %) Total Reactive Losses: 0.000327173 Mvar Running the same simulation but in yearly mode gives me: Total Active Power: 0.0105469 MW Total Reactive Power: 0.00346773 Mvar Total Active Losses: 2.85093E-005 MW, (0.2703...

Hello all, As the title says, I have acquired ENW’s (a UK DNO) LV network for a power loss optimisation project. I am trying to recreate the plot shown below (I.e. multiple feeders extending out from a common transformer busbar). From the research I have carried out in previous forum posts, I see that the best way to separate feeders is to use the “energymeter” command and connect it to the first bus on the feeder. My issue is that whenever I try to execute my script, I get an error saying: “Warning:...

I'd just like to add for anyone else who finds this thread that has the same confusion as me, the LINECODE objects I listed are a mix of metric (185mm^2, 70mm^2, 35mm^2 etc) and imperial(.0225Inch, .06Inch) sizes. :)

Thank you Roger, I managed to find a copy Kersting in my Uni library. Thank you for your explanations, very clear.

Hi everyone, I have been learning some OpenDSS code/ modelling for my final year project. I’m trying to wrap my head around what LineCode objects physically represent. I know they represent Distribution cables but for example, am I correct in saying that... New LineCode.4c_.35 nphases=3 R1=0.089 X1=0.0675 R0=0.319 X0=0.076 C1=0 C0=0 Units=km New LineCode.4c_185 nphases=3 R1=0.166 X1=0.068 R0=0.58 X0=0.078 C1=0 C0=0 Units=km New LineCode.4c_70 nphases=3 R1=0.446 X1=0.071 R0=1.505 X0=0.083 C1=0 C0=0...
