Adjustment of Two Circuits System of Active Shielding of the Magnetic Field Generated by Overhead Power Lines

Abstract

The method of adjustment of a two-circuit system of the active shielding of the magnetic field generated by single-circuit overhead transmission lines with a triangular arrangement of wires based on experimental measurements space-time characteristics was developed. The problem of synthesis of two degree of freedom robust two circuit system of active shielding of initial magnetic field comes down to a decision of the multi-criteria two-player zero-sum antagonistic game. During the design of system spatial location coordinates of two shielding windings, the currents in the both shielding windings and the vector of parameters of regulators were determined. The vector of payoff game calculated based on Biot-Savart's law. The game decision calculated based on the stochastic particles multiswarm optimization algorithms. Computer simulation and field experimental research of two circuit system of active shielding of magnetic field, generated by overhead power lines with phase conductor's triangle arrangements are given. The possibility of initial magnetic field reducing to the sanitary standards level is shown.
