Neural Network-Based Fault Distance Estimation For Multi-Terminal Dc Microgrids, Mohamed Elmadawy, Abdelhady Ghanem, Sayed Abulanwar, Ahmed Shahin

Mansoura Engineering Journal

Fault distance estimation in DC microgrids is a critical issue due to the growing adoption of DC-based distribution systems. Current methods face limitations like sensitivity to system parameters and high-resistance fault detection, necessitating improved accuracy. This study proposes a neural network approach to accurately locate fault distances in multi-terminal DC microgrids. Three different structures based on backpropagation algorithms are developed and trained to estimate fault distances with high precision. These structures can handle various fault scenarios, including different fault resistances and the presence of noise. Two of the structures can predict fault distances from one side locally, achieving low error …

Analysis Of A Coaxial Magnetic Gear Optimally Designed Using Particle Swarm Optimization, Yasser Kassab, Abdelhady Ghanem, Eid Gouda

Mansoura Engineering Journal

One important key to improve the efficiency of adjustable speed drives is using magnetic gears due to their advantages in comparison to their mechanical counterparts. This paper introduces an analysis study for a magnetic gear optimally designed using the particle swarm optimization algorithm (PSO). Moreover, the results of the PSO-based design are compared with the results of another optimization design process based on a genetic algorithm for the same design parameters and constraints. The proposed magnetic gear topology to be optimized is a radially magnetized coaxial configuration with a surface-mounted permanent magnet array. The gear ratio of the proposed magnetic …
