Abstract For overhead transmission lines, three conductors, Aluminium Conductor Steel Reinforced-ACSR, All Aluminium Alloy Conductors-AAAC and Aluminium conductor Composite Core-ACCC are deployed. Initially, in this work, we describe the generating technological characteristics of the conductors. We made an analysis of the physical, mechanical and electrical characteristics. We tested the ACSR, AAAC and ACCC conductors in the overhead transmission line on one... Read More

Abstract Magnetic fields in the region where people live have direct and indirect effects leading to multiple issues. Magnetic field effects from conduits, high-voltage fixtures and transformation stations affect the environment considerably. Using the finite element method with FEM 4.2 at normal loads, we identify the effect of the magnetic field in the environment. The volume of the magnetic induction in... Read More


Power Stability and Quality Improvement using Ideal DFIG

Abstract The transmission power system has the first DFIG wind farm, and its dynamic characteristics are studied in this paper. We measure it using the MATLAB/SIMULINK tool to study the behaviour. We have designed the wind turbine and power system with real-life data. We intend to improve the power stability and quality for which we find how the DFIG works in... Read More
