摘要

高压输电线路在线监测装置能有效提升电力系统的安全性与稳定性，是智能电网的重要组成部分。然而，在实际应用中，供能问题一直是制约在线监测装置发展的关键瓶颈。为满足在线监测装置稳定可靠的用能需求，本文基于电场感应取能原理，提出并开发了一套从高压输电线路周围的高压电场中拾取能量的空间取能系统。首先，给出了空间取能的系统结构，并分析了系统的工作原理。然后，对空间取能所用的耦合极板进行了优化设计，使用环框型耦合极板实现了取能功率和极板尺寸之间的平衡。进一步的，根据取能系统准电流源输出的特点，设计了DC/DC降压电路，大幅提升了系统的输出功率。最后，针对在线监测装置的断续用能需求，设计了滞回充放电逻辑。理论及实验结果均表明，该系统可以稳定输出25mW以上的电能。经储能模组存储后，可以满足在线监测装置每2小时进行一次拍照回传的工作需求。

Abstract

High-voltage transmission line online monitoring device can effectively promote the safety and stability of the power system

thus acting as an important part of the smart grid. However

for practical applications

the power supply problem is always the key limitation that restricts the development of online monitoring device. To provide stable and reliable power supply to the online monitoring devices

a space energy harvesting system based on the electric field induction is proposed to pick up power from the high voltage electric field around the transmission lines. Firstly

the system structure is demonstrated

with the analysis of the system’s working principles. Then

the coupling plates for space energy harvesting is optimized

with the use of frame-shaped plates to seek a balance between the power level and the system sizes. Furthermore

based on the sys-tem’s quasi-current source characteristics

a DC/DC converter is designed to notably improve the output power level. Finally

with respect to the discontinuous power demand of the on-line monitoring device

a hysteresis discharge mechanism is de-signed. Both the theoretical and the experimental results show that the system is able to output more than 25mW power sta-bly. With the use of energy storage module

the on-line monitoring device is able to upload the picture information every two hours.
