Topology optimization of magnetic energy converter in high-voltage substation

Aiming at the application problems of wireless sensors in power substation, the wraparound topology of magnetic energy converter is proposed. In high-voltage substations, there is a fairly wide range of the spectrum in the magnetic field components. If magnetic energy converter with better collection efficiency is used as auxiliary power source, it will be able to significantly improve the self-powered strength. Thereby wraparound mathematical models of different magnetic energy converter topologies are established and the mutual inductance factors (M) to characterize the collecting ability of magnetic energy are defined. With regard to magnetic skeleton material, skeletal structure parameters and the number of coils in different magnetic energy converter topologies, the optimization of mutual inductance factor is analyzed in detail. As a result, the wraparound magnetic energy converter design principles are obtained and the overall performance of magnetic energy converter is validated by simulation verification.
