A Comprehensive Literature Review of Wound Rotor Induction Motor Drive System by Rotor Impedance Variation

To improve Wound Rotor Induction Motor (WRIM) drive system performance, this work offers a comprehensive literature assessment of an adjustable speed drive with a variety of control approaches of rotor impedance variation. It begins with a synopsis of the key elements of the WRIM drive system control approaches and moves on to discuss other control strategies, such as non-static impedance control, static rotor resistance control, dynamic capacitor in rotor circuits, and optimal controlling like artificial neural network, fuzzy logic control, PSO and genetic algorithms have been reviewed in this paper. It also looks at how these strategies affect motor performance, efficiency, simplicity, reliability, economically, dependability, and operational flexibility. The results highlight how important rotor impedance control is to maximizing WRIM performance and how continuous innovation is being made to make them more useful in a variety of industrial settings.
