Optimization of electric and magnetic field intensities in proximity of power lines using genetic and particle swarm algorithms
The paper presents optimization of power line geometrical parameters aimed
to reduce the intensity of the electric field and magnetic field intensity under an overhead
power line with the use of a genetic algorithm (AG) and particle swarm optimization (PSO).
The variation of charge distribution along the conductors as well as the sag of the overhead
line and induced currents in earth wires were taken into account. The conductor sag was
approximated by a chain curve. The charge simulation method (CSM) and the method
of images were used in the simulations of an electric field, while a magnetic field were
calculated using the Biot–Savart law. Sample calculations in a three-dimensional system
were made for a 220 kV single – circuit power line. A comparison of the used optimization
algorithms was made.
