- Insert a three-phase source.
- Connect the output of each phase to an ‘ideal switch.’
- Insert a ‘pulse generator.’
- Connect the output of the ‘pulse generator’ to the ‘gate’ terminal of ‘ideal switch.’
- Adjust the width of the pulse the pulse generator as required.

How the fault incipient angle of three phase fault applied to transmission line modelled using RL can vary? And how the fault location in the transmission line can vary?

Hey Nirma,
I understand that you want to vary the fault incipient angle and the fault location of three phase fault applied to a transmission line which is modelled using RL.
To vary the fault inception angle in a Simulink model, you can use a controlled switch (or a set of switches for a three-phase system) to initiate the fault at a specific point on the voltage waveform. You can control the timing of the switch using a ‘Simulink pulse generator’ or a ‘function’ block that calculates the appropriate time delay based on the desired inception angle and the frequency of the system.
Here is a basic approach:
To model the fault location along a transmission line in Simulink, you can use the ‘Distributed Parameters Line’ or ‘π-Section Line’ block to represent the transmission line.
You can then divide the line into segments and place a fault at a specific segment to represent the fault location. The impedance of each segment will be proportional to its length.
To know more about modelling fault, please refer to the following documentations:
Hope this helps.
