Modeling and Active Shielding of Magnetic Field with Circular Space-Time Characteristic and with different Shielding Coils spatial positions

The circular space-time characteristic of magnetic field generated by overhead power lines with triangular conductor’s arrangement and with different spatial positions of two shielding coils has been simulated. System of active shielding of magnetic field with two degree of freedom robust control and with different spatial positions of two shielding coils are synthesized. The multi-criteria game decision based synthesis. The Maxwell equations quasi-stationary approximation solution based calculated payoff vector. The stochastic particles multiswarm optimization algorithms based game decision. It is show that synthesized system of active shielding reduced initial magnetic flux density to the sanitary standards level in shielding space located near the overhead power lines.
