The paper presents optimization of line parameters in order to reducing the intensity of the electric field with the use of particle swarm optimization (PSO). Simulations of the electric field intensity have been curried out for a different heights and distances for a building wall located in the vicinity of a power line.

The paper presents the results of computer simulation of the operation of a lighting installation disturbed by a voltage surge of 1.2 / 50 μs. The components included in the model of the system were: voltage surge generator (accordance with the PN-EN 61000-4-5 Standard), coupling - decoupling system, over-current circuit breaker, iluminance level controller and incandescent lamp. The results of simulation tests with the results of tests carried out in an accredited electromagnetic compatibility laboratory were compared.

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. [ABSTRACT FROM AUTHOR]
