| description | In power systems, it is challenging to identify the faulty line and fault distance when compensating devices are present in the system. This work presents a fault locator using an Adaptive-Network-based Fuzzy Inference System (ANFIS) that accurately estimates the fault location on a compensated line in conjunction with an active power differential-based backup protection algorithm for faulty line identification. Both the faulty line identification algorithm and the ANFIS-based fault locator utilise the positive and negative sequence voltage and current phasors generated by the Phasor Measurement units (PMUs) placed in the system. The ANFIS-based fault locator is trained and tested using the simulated fault data obtained with a MATLAB Simulink model of a modified WSCC 9 bus system. The training data is generated by varying the fault distance in steps of 10 km. The line-to-line resistance (Rf) of <inline-formula> <tex-math notation="LaTeX">$0.01~\Omega $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$0.1~\Omega $ </tex-math></inline-formula> & <inline-formula> <tex-math notation="LaTeX">$1~\Omega $ </tex-math></inline-formula>, and the line-to-ground resistance (Rg) <inline-formula> <tex-math notation="LaTeX">$1~\Omega $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$10~\Omega $ </tex-math></inline-formula> & <inline-formula> <tex-math notation="LaTeX">$100~\Omega $ </tex-math></inline-formula> are used with different types of faults (LG, LLG, LLLG, LL& LLL) for training. Two ANFIS structures are trained for the fault distance estimation in compensated line - one for Static Synchronous Compensator (STATCOM) and the other for Static Synchronous Series Compensator (SSSC). Simulation results show the fault locator estimates the fault location accurately with a 5% tolerance in all the fault conditions simulated. |
