I am currently using DigSILENT to make the IEEE 9 bus test feeder system and conduct an experiment.
First, I installed three photovoltaic systems in the 9 bus system.
In addition, I am conducting a study to check the frequency and rotor angle by making a fault to the system and clearing it.
After the fault, the PV closest to the fault location was switched open. Then, after clearing the fault, the PV is reinjected.
However, to check the Rotor angle first, when G1 is set as a reference machine and G2 and G3 rotor angle with reference to reference machine angle is plotted, a graph like the Nine-bus system tutorial provided by DigSILENT is not displayed.When performing RMS/EMT simulation, the simulation method and Network representation are RMS values and unbalanced 3-phase (ABC), respectively. In addition to these, I would like to know what I need to check for rotor angle.
Dear Jang Jiyeon,
I suggest you see links maybe that it can inspired you to found a solution for your problem.
