摘要
无线电能传输(wireless power transfer,WPT)技术能够以无线的方式传输电能,与传统输电方式相比优势明显。在电力系统无人化、智能化的趋势下,采用磁耦合谐振式无线电能传输技术有助于解决电力系统智能化设备的无线供电问题。介绍了磁耦合谐振式无线电能传输技术在电力系统中的几种应用场景,分别是电动汽车无线充电技术、变电站电力巡检机器人无线充电系统和线路巡检无人机无线充电系统,从系统结构出发,对最近研究成果进行对比分析,认为在充电效率、大功率充电、系统稳定性以及双向无线电能传输方面仍然存在研究空间,并对未来的研究方向提出建议。
Wireless power transfer(WPT)can transmit electric wirelessly.It performs better under some paticular circumstances compared with the traditonal transmission mode.In the trend of building a smarter power system,the vast majority power supply problem of these smart equipments can be solved by using magnetic coupling resonant WPT.This paper introduced several possible application of magnetic coupling resonant WPT in power system,including the electric vehicle(EV)wireless charging system,substation power inspection robot wireless charging system and unmanned aerial vehicle(UAV)wireless charging system.Starting from the structure of the system,this paper compared and analyzed the recent research results,and drew conclusions finally.There still exists some issues to be settled in terms of charging efficiency,high-power charging,system reliability and double-direction WPT.At the end of this paper,several suggestions were proposed.
