摘要

摘要利用无线传感器实现了智能电网中高压设备的实时监测。它们确保可靠的电力传输，避免级联电源故障。远程为这些传感器供电是一个挑战。本文提出了一种利用磁场采集器远程为传感器供电的新方法。设计并优化了一种哑铃形磁芯，用于采集变电站高压母线/变压器附近的磁场。收获的能量被整流和提升。设计阻抗匹配电路，以获得最大的功率传输到无线传感器。这样收集的能量被用来为无线传感器供电，使它们自我可持续发展。实验结果表明，当磁通密度为9µTrms时，40000匝磁芯可获得17.6 mW的输出功率。

“Design and development of magnetic field harvester to power wireless sensors in smart Grid”

Abstract Real time monitoring of high voltage devices in smart grid is implemented using wireless sensors. They ensure reliable power transfer and avoid cascading power failures. Powering these sensors remotely is a challenge. This paper presents a novel method of powering sensors remotely using magnetic field harvester. A dumbbell shaped magnetic core is designed and optimized to harvest magnetic field near high voltage bus bars/transformers in electrical substation. The harvested power is rectified and boosted. Impedance matching circuit is designed to obtain maximum power transfer to the wireless sensor. The energy thus harvested is used to power wireless sensors and make them self sustainable. The experimental results show that the proposed core with 40,000 turns can harvest 17.6 mW of output power when placed in magnetic flux density of 9 µTrms.
