Mitigation of Magnetic Fields in Overhead Power Lines Through Genetic Algorithm-based Electromechanical Compensation

Strategic Insights -

A recent study published in the Journal of Magnetism and Magnetic Materials has proposed an advanced approach to mitigate magnetic fields generated by overhead high-voltage transmission lines. The research, conducted by a team of scientists from Fayoum University, suggests that combining electrical compensation optimized using a genetic algorithm (GA) with mechanical reconfiguration of overhead transmission lines can achieve optimal magnetic field mitigation. According to the study, the proposed method can improve the mechanical rearrangement method by approximately 29% in one case and 70% in another, indicating a significant reduction in magnetic field levels.

Key Takeaways:

  • The magnetic fields generated by overhead high-voltage transmission lines have significant health risks, which can be mitigated through various techniques, including electrical compensation and mechanical rearrangement.
  • The proposed method integrates electrical compensation optimized using a genetic algorithm (GA) with mechanical reconfiguration of overhead transmission lines to achieve optimal magnetic field mitigation.
  • The genetic algorithm is an evolutionary optimization method that provides multiple solutions and does not require complex modeling, unlike traditional optimization methods.
  • Passive-reactive compensation has a less significant effect on magnetic field mitigation than mechanical rearrangement because current control is not continuous and is limited by reactive elements.
  • However, the lowest possible magnetic field levels are achieved when electrical compensation is combined with mechanical compensation.
  • The study tested two cases using the proposed method and found that electrical compensation improves the mechanical rearrangement method by approximately 29% in Case 1 and 70% in Case 2.
  • The researchers, led by Eslam Mohamed Ahmed, Fayoum University, Faculty of Engineering, Dept. of Engineering Mathematics and Physics, Al Fayyum 43518, Egypt, included Ahmed Sayed Abdelrazek, Ali Alkhafa, and Khaled Hosny Ibrahim as additional authors.
