Monitoring Fault Diagnosis Based on Phasor Measurement Unit at Wide Area Systems

Increasing fault diagnosis of the electric power transmission system is vital to reducing power outages to consumers. Several methods are employed to determine fault diagnosis in electric power transmission lines. The purpose of the work is to monitor fault diagnosis using Phasor Measurement Unit (PMU) at Wide Area Systems. Measurement is performed by monitoring, controlling, and protecting by combining the functions of the phasor measurement device. PMU is a part of measuring the phasor of current and voltage values at the control center. So, this study was intended to design 9-bus systems IEEE based PMU using the software. The simulation is performed in a state of three-phase short circuit faults. It is then tested on all lines on the 9- bus systems IEEE with variations distances of 10%, 30%, 50%, 70%, and 90%. The simulation results are used as input for the fault diagnosis to determine the point of fault location on the 9-bus systems IEEE. Furthermore, it can calculate the error value, Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) of the three-phase short circuit fault diagnosis on each line of the 9-bus systems IEEE. The highest error value obtained on Bus-7 to Bus-5 of fault location distance of 90% is 0.48 %. RMSE is 3.02*10
