The fault inception angle can be varied in Three-Phase Fault bloc in simulink. you should complete box of transition times corresponding to angles faults (in voltage signals)
you should take the time corresponding to the angle from the voltage signals.
The time corresponding to the maximum voltage (angle = 90 °) is 20 ms, for example.
Hi F.L. Yousfi sir
it's my problem too.but i don't understand how solving the problem.
is there a block for this purpose in simulink?
Hello,
Yes, there is a bloc in simulink called Three-Phase Fault bloc. You can vary transition times corresponding to angles faults.
I know that there is Three-phase Fault bloc.but fault inception angle mean's "It the angle between fault current and voltage at the point where the fault occurs".Is this true?
if this is true, I have measured the angle between the voltage and current. for example, to have fault inception angle equal to zero, current and voltage must be in phase.
thank you so much.
In three phases fault breaker my fault is starting and clearing [0.02 0.1] in this interval .now I want to add 45° degree angle in starting time .what is my starting time value?please provide me formula, so I can calculate the value for another inception angle.Thank you.
Hello,
Sorry for delay, but I don't see the conversation in past. Is it ok for your simulink model ?
I can explain more if you have some problems.
I am working with Artificial Neural Network. My Project is based on " Development of artificial neural network for transmission line fault protection". My problem is associated with fault inception angle. I alerady taken dataset for training the ANN . In the dataset, i have not consider the fault inception angle. My fault breaker is operate(start time) at 0.02 sec and clear the fault (stop time) at 0.1sec. I have not taken various inception angles in my dataset.while i am operate my fault breaker (start time) at 0.025sec. Than ANN provide me garbage values. I know that the ANN is not train for various fault inception angles.suppose i will take dataset for various inception angle.Than my dataset becomes large for each case.This process taking too much time.so my question is that, which type of training, I have provide the to ANN without consider large dataset.Is there any other method to train the ANN, so it can provide me some relevant values for the different fault inception angle?
Sir,Did you get the answer? I am also facing challenge in varying the fault incipient angle of Transmission line modeled using RL
