    Since I'm very new with this product and as far I gone through the manual there are no any clear understanding. Is there anyone who can provide me with a simple sample project in order to grap this product quickly

    Pulendran,

    I suggest that you watch the OpenDSS videos on Youtube: https://www.youtube.com/watch?v=RGbfIfhGcRg&list=PLcOap2oqW_gEMEVH9dg2HoXJ4NvydfsZM

    Best regards,

      Paulo Radatz,

      Thankyou so much for sharing this link. But this link is very basics. I want to know in much deatailed about this software

        Hello Pulendran,

        I think Paulo's videos have the good basics and more than the basics you might need. So, those are pretty good videos to follow and learn. I benefitted a lot from these videos. It also gives you an insight about forming the matrices by which OpenDSS solves the power flow problem. Moreover, OpenDSS primer and OpenDSS manual documents are good one to start with. These documents comes with the installation itself.

        Thanks,
        Rakesh

          Hello Rakesh Belcandan,

          I have gone through this videos thanks it helped me a lot. Is there any ways to differenciate nodes and busbar. Did openDss have any specific code to create ony nodes without bus bar.

           
          • Rakesh Belchandan

            Can you please tell what are you trying to do? When you define an element you need to define to and from bus in case of power delivery element and bus1 in case of power conversion element. Then you define connectivity nodes (Phases A.B.C) in the buses for those PC and PD elements.

              Dear Rakes Belchandan,

              Im clear with the idea that we can add loads to the bus bar, if it is a single phase it can add single node from bus bar and if it is a three phase it can add 3 nodes for each phase in bus bar, which is automatically done when we given a load to bus bar by openDss.

              My question is there are instances where only nodes are included in connection. For an example to connect the LV side of the transformer to the LV busbar we have to get a cable from the LV side of the transformer to LV bus bar. For this purpose we only need a 3 phase node from LV side of transformer to LV busbar. I'm asking that can we create nodes seperately without creating a busbar.

              For better understanding I have included a diagram please refer it.

                The objects definition needs "to and from bus" so in your case, it is needed to define that bus for a transformer secondary.

    I got the same question. I need to know if several loads are connected to a bus, can we define each nodes in that bus inorder to measure the voltage of each node in the bus. I couldnt find that in the manuals.

    Yes, you can connect several loads to a bus.

    when we connect several loads to a single bus and then PVs defined for all the loads. then we encountered an error. error was all the line voltages are 230V. its our base voltage

    Please elaborate on the error. I don't understand your problem.
