Method for Design of Magnetic Field Active Silencing System Based on Robust Meta Model
摘要
Overhead power lines generate magnetic fields inside residential buildings, the level of which is often 3–5 times higher than safe living norms. Therefore, all over the world, methods to reduce the level of the magnetic field in existing residential buildings located near power lines intensively developed. The paper proposes a new method design for a system of active silencing to reduce the magnetic field generated by aerial transmission line groups inside residential buildings. First stage research designs a robust meta model based on the exact model and experimental measurements of initial magnetic field. Both these problems were reduced to two zero-sum antagonistic vector game solutions. Both vector games’ payoffs are estimated using Biot-Savart law. Multi-swarm stochastic optimization algorithm was used to calculate both games’ solutions. Second stage research was computer simulation of a system of active silencing magnetic field and experimental research.
