摘要

本研究建议在大都会电力局(MEA)安装的69/115千伏地下电力系统中采用无源磁场缓解技术。利用有限元电磁学(FEMM)程序，设计并仿真了导电回路、导电屏蔽和铁磁屏蔽三种无源技术。得到了有和没有减缓系统的磁场的比较。最后，仿真结果表明，所有被动技术都能将磁场值降低到低于国际非电离辐射防护委员会(ICNIRP)和欧洲标准给出的参考值。

Passive Techniques for Magnetic Field Mitigation in Underground Power Systems

This research proposes passive techniques for magnetic field mitigation in the 69/115 kV underground power system installed by the Metropolitan Electricity Authority (MEA). The passive techniques which are: conductive loop, conductive shield, and ferromagnetic shield were designed and simulated by using the Finite Element Method Magnetics (FEMM) program. A comparison of the magnetic field with and without a mitigation system is obtained. Finally, the simulation results show that all passive techniques can reduce the magnetic field values to be lower than the reference value given by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and European standards.
