Abstract

Electromagnetic fields (EMFs) generated by overhead
transmission lines can have noticeable impacts on the surrounding
environment. High-intensity EMFs can have potential health effects on
humans living or working near transmission lines. Mitigating these EMFs
is crucial to ensure the safety and well-being of individuals residing near
these power lines. EMFs mitigation could be accomplished through either
electrical compensation or mechanical line rearrangement. In the present
research, the passive reactive compensation method is combined with
mechanical rearrangement of power conductors to optimize the resultant
EMFs above ground level as minimum as possible. Genetic Algorithm
(GA) is used to achieve this objective by encoding both of the conductor
positions and proposed reactive elements for each phase as genes. Results
show that Electrical compensation improves the mechanical
rearrangement method by about 33% (total reduction with mechanical
compensation only about 34% is increased to more than 52% with
electromechanical compensation). At last, different fitness functions are
utilized to mitigate both electric and magnetic field. The results show
about 47% reduction in both electric and magnetic fields.
