Abstract

This study presents a comprehensive approach to the modeling, simulation, and analysis of single line-to-ground (SLG) fault detection in high-voltage power transmission systems. A dual-unit detection system was developed, integrating a MATLAB/Simulink-based simulation model with a microcontroller-based hardware unit for real-time fault identification and communication. The simulation model replicates the behavior of a 132 kV transmission line under various SLG fault conditions, while the hardware unit employs voltage and current sensors connected to an Arduino Uno and GSM module to detect faults and transmit location alerts. Experimental procedures included controlled fault injection, waveform analysis, and algorithmic fault distance estimation using zero-sequence currents and voltage dips. Simulation outcomes demonstrated high location accuracy, with error rates consistently below 0.75% across a fault distance range of 30–300 km. The system exhibited fast response times, high precision, and cost-effectiveness, indicating strong potential for deployment in power grids of developing regions. The integrated software-hardware architecture offers a scalable and efficient solution for minimizing downtime and enhancing fault response coordination in transmission networks.

Abstract

This study presents a comparative performance analysis of Proportional-Integral-Derivative (PID) and Tilt-Integral-Derivative (TID) controllers in the context of azimuth positioning for a parabolic dish antenna system. A detailed system model was developed in MATLAB/Simulink, integrating key components such as motor dynamics, amplifier behavior, potentiometer-based feedback, and gear mechanisms. The performance of both controllers was evaluated under ideal conditions and in the presence of environmental disturbances, with wind effects modeled using the Dryden wind turbulence model to simulate real-world scenarios. Key performance metrics, rise time, settling time, overshoot, and steady-state error were used to assess controller efficacy. The results indicate that the PID controller outperforms the TID controller in terms of stability, accuracy, and resilience to disturbance. Although the TID controller exhibited a marginally faster initial response, it suffered from greater overshoot and reduced stability, particularly under wind-induced disturbance. These findings underscore the robustness and suitability of PID control for high-precision antenna positioning systems, while also suggesting that enhancements to TID control may be possible through optimization techniques or hybrid controller designs.

Abstract

This paper addresses the need for accurate and timely single-line-to-ground (SLG) fault detection in high-voltage transmission systems, particularly to improve grid reliability in developing regions. The research objective is to propose and validate an integrated framework that combines modeling, simulation, and real-time implementation for SLG fault identification and location. Methodologically, a dual-unit detection scheme was developed: a MATLAB/Simulink dynamic model emulating a 132 kV transmission line under diverse fault scenarios, and a microcontroller-based hardware prototype employing voltage and current sensors interfaced with an Arduino Uno and GSM module to detect disturbances and transmit location data; experimental validation involved controlled fault injection, waveform inspection, and fault distance estimation via zero-sequence current and voltage dip analysis. Key findings show high-precision fault location with estimation errors consistently below 0.75% over a 30–300 km range, alongside fast response, accuracy, and cost-effectiveness. The study concludes that the combined software–hardware architecture reliably detects and locates SLG faults. The contribution and implication are a scalable, low-cost approach to reducing fault-related outages and enhancing fault management in transmission networks.
