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:
- 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.
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.
