Hi, I need to apply three phase to ground fault on bus number 5(in 9 bus system) with 2&3 cycles. Then remove the fault without tripping. How can I apply fault with cycles? I don't understand cycles mean. What specifically I have to choose? Thanks in advance.
Frequency is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. You may contact us at psscommunications1@gmail.com for further discussion.
Thanks. It was help full. I have one question. If I limited my Pmax, why the generator not respect this limit and exceeds it? your help would be very helpful
In steady state, the output of generator will be equal to Pgen except for the swing bus in which the output will be such that the frequency of system is maintained.
Hello Sir: Excuse me, if I am doing transient simulation analysis in psse, it is no problem when I put in a general bus fault, but when I want to create a single-phase fault or phase-to-phase fault, it will display like an error message such as {messages for api dist_scmu_fault no sequence data in memory (004438)} How should I proceed at this time, please tell me, thank you! Sincerely, Kevin LIN
That was to the point and informative. Thank you! One question. I am using PSSE University version and when I'm gonna perform the Dynamics simulation and initialization, the Run button is inactive. Is it because of the limitation in university version? I thought the only limitation with this version is the number of buses.
@@sofoklistsantzalis5881 Yes we can also simulate an unbalanced fault. From file menu of PSS/E goto Disturbance -> Calculate & Apply Unbalanced Bus Fault.
System can be unstable due to various reasons including voltage issues, inertia, power flows etc. You need to identify the cause. You can share your issues @ psscommunications1@gmail.com
Follow the video @ 12:17. From this plot, you can find the value of power flow during pre-fault, during fault and in post fault scenarios. Also, you can plot this graph for any transformer or transmission line.
Good for your motivation and work but you need to be more specific. Create a SLD and case from scratch and to simulate a wind turbine or a pv panel. This was general

Very Useful. Thanks

Hi, may i know how you get the value for parameters for genrou, IEEET1 and HYGOV?

Which fault was that u applied in Bus fault? Is it 3 phase fault or short circuit fault?
This is a 3 phase bus fault.

Is it because of the limitation in university version? I thought the only limitation with this version is the number of buses.
No, it is because of Initialization errors. Once the errors are removed, then Run will be accessible.
@@PowerSystemSimulation Thanks, it's resolved.
Hello, nice content! Any reason behind the tuning of the solution parameters?
The parameters are tuned to enhance the flexibility of solution by enhancing number of iterations, changing simulation time step etc.
If we want to test an unbalanced fault(for example solid line ground) and we have the sequence data we use 0 and -20000000 or 0 0?
And in general is it possible to do a dynamic transient stability analysis of an unbalanced fault?
@@sofoklistsantzalis5881 Yes we can also simulate an unbalanced fault. From file menu of PSS/E goto Disturbance -> Calculate & Apply Unbalanced Bus Fault.
But the values of reactance and resistence are zero right? Because in the 3 phase fault it is 0 and -2000000000
@@sofoklistsantzalis5881 for worst case scenario, keep the values Zero
thank you my life saver

I am facing problem in dynamic simulation of PV system. Can u help me? System is not gonna converged after applying fault.

@@PowerSystemSimulation sir kindly check email.
I want to calculate the power flow when there is a short-circuit in the electrical system. help me

Sir I need help to run ESTR/ERUN for exciter paramters validation
Sir it will be a great pleasure to help me in exciter parameters validation
@@zeeshansadiq6150 We will guide you regarding ESTR/ERUN soon.
@@PowerSystemSimulation sir it's a great pleasure . waiting for ur videos. Thanks in advance
How could I create a Dynamic file?
You can write a .txt file and then save it as .dyr
Also, you can create using PSS/E itself.
Good for your motivation and work but you need to be more specific. Create a SLD and case from scratch and to simulate a wind turbine or a pv panel. This was general
We will also run dynamic simulation on the base case prepared in Tutorial #6. That base case was prepared from scratch.
Very good.. I will be glad to share it on my LinkedIn. It will help you a lot since i have great reputation and connections there
@@powertohuman Appreciate it.

heloo, can you get me contact? I have some question
