Hello Roger! How I hadn't thought of that. This script of yours already helps me a lot. As Armstrong says: "It is a small step for man, a giant leap for humanity", or rather a giant leap for an engineer. Thank you.

Hello Roger! You're right, Line elements are not PCElements, it was my fault. I tried to put a load element, but did not provide any variables. I believe that there is no PCElementos that has variable as residual voltage (V0 or VN). As for the directional element (67), the negative sign did not work. The solution will be to have the current module angle, as it is the only element that can indicate the reverse of the current. As for the suggestion of using a reactor, I will study it more carefully....

Hello Doctors !!! Regarding the Relay object, can I use type = generic to control the residual voltage (59N) of a PC element (line object)? If so, what is the name of the variable I should use? Where can I get the list of variables that we can use for each PC Elements Another question: 1) is it possible to use as a directional overcurrent (67 / 67N) for the same MonitoredObj? 2) how can I use a time delay only for neutral overcurrent (50N)? Grateful for the attention. Luciano.

Hello Roger! I confess that I was not able to interpret the information contained in the Trace_ControlQueue.CSV file very well. In the OpenDSS manual there is not much detail, is there another place that I can get more information about each action recorded in the file? Well, in relation to my case, the problem really was in the time step. Then I changed the stepsize = 0.01 and number = 1000, the simulation occurred as expected, that is, opening only the element RL03060. I am slowly learning more...

Davis, As I already mentioned, I wanted to check the voltage on the busbars of the circuit during the pre-fault and post-fault, since the Transformer.UT_MGD_PV transformer (photovoltaic coupling transformer) is delta in the primary. The intention is to insert a short circuit (three-phase, two-phase, single-phase) on all buses and observe voltages on the other buses. However, one of the cases caught my attention. That is, when I apply a short circuit, for example, on the ps_26608 bus (fault.falta_26608_3f),...

Hello Davis! I changed it to a single source, as described below: New Circuit.VIA1-16 Bus1=SE_VIA1 ~ basekv=23.1 Angle=90 Frequency=60 Phases=3 ~ r1=(0.02922 5.29 ) x1=(0.30841 5.29 ) r0=(0.00676 5.29 ) x0=(0.07424 5.29 ) However, when applying the short circuit, it continues to open both protections, that is, it is not respecting the coordination time. Tell me, did the simulation run perfectly with you, that is, did you open only the element RL03060? Why are you opening the DJ_16 element together...

Dear Davis, I am analyzing only the occurrence of a short circuit in several buses in the distribution network and observe the voltages during pre-fault and post-fault on the PS_31634 (photovoltaic plant) bus. So I came across this problem of coordination between two protective devices, however when I increase the dj_via1_16 relay time dial to 0.15, for example, the system is coordinated, but it should also be dialed at 0.13. So I don't see the need to load the circuit to perform a short circuit...

Hello Davis! No! Only one source (via1-16). The system must have created it when I converted from DSS to DSP. I hadn't realized that. Could these two sources be causing the problem? Attach the attached file used for the conversion. Grateful for the attention.
