Hi Siddharth,
I do not have much knowledge in the power system transmission line models. So, I cannot directly help you with your code. However, I can guide you on possible ways how you can achieve this.
When the three-phase to ground current has equal amplitudes during a fault condition, it can be difficult to discriminate between the faulted phase and non-faulted phases based on the current amplitudes alone. In such cases, other methods can be used to determine the faulted phase. Here are some approaches that you can try:
- Phase comparison method: In this method, the phase angle difference between the voltage and current signals of each phase is compared. During a fault, the phase angle difference of the faulted phase will be different from the other phases. This method requires accurate phase angle measurements.
- Symmetrical component method: In this method, the positive, negative, and zero sequence components of the current signal are calculated. During a fault, the positive sequence component of the faulted phase will be different from the other phases. This method requires accurate sequence component calculations.
- Wavelet transform method: In this method, the current signal is decomposed into its time-frequency components using wavelet transform. The features of the wavelet coefficients can be used to discriminate the faulted phase from the non-faulted phases.
You can try these methods and see which one works best for your case.
Hope it helps.
