摘要/Abstract

摘要： 电力输电线路在线监测设备的持续稳定供电一直是亟待解决的难题之一。针对这个问题，结合高压取电技术，设计了一种基于磁场共振耦合的无线供能装置，受天气影响小，基本无需维护，实现对在线监测设备的可靠供电；为保证装置有足够的电能输出，通过分析输出功率的变化情况，采用最大功率点控制实现电能的稳定输出。经国家专业检测机构进行了工频耐压、电能稳定输出和调谐控制专项测试，工频耐压测试后系统工作正常，模拟导线电流在200~1 000 A时能保证发射端的稳定输入，增加频率调谐控制后可使输出功率提高2倍以上。测试结果表明装置能在1.1 m传输距离内实现稳定的电源输出。

Abstract: Reliable power supply for the online monitoring equipment of power transmission lines is one of the most urgent problems needing to be solved. For this purpose, a magnetic resonance coupling-based wireless power supply device is designed，which is convenient for maintenance and free of weather influence. On the basis of analyzing the output power of the wireless power supply device, the maximum power point tracking control system is used to ensure a stable power output. The device has been tested by the dedicated state-own inspection agency in power frequency withstand voltage, power output and tuning control, which shows that the device can work normally after power frequency withstand voltage testing and can provide stable outputs throughout the range of simulated power line current varying from 200-1 000 A, and the output power can increase by more than two times after adding frequency tuning control. The testing result proves that the device can provide a stable power supply in a transfer distance of 1.1 m.

Key words: wireless power transfer, magnetic resonance coupling, online monitoring, smart grid, non-contact
