中文摘要:
      摘 要: 交流输电线路的在线监测与信息互联是建设泛在电力物联网中至关重要的一环,但是为监测设备稳定供能是研究难点,利用电流互感器为交流输电线路监测设备供能前景广阔。交流输电线路电流变化范围大传统的电流互感器供能不稳定,为了提供稳定的输出功率,文中提出了一种电子负载并联在电流互感器二次侧通过阻抗匹配调控使电流互感器从交流输电线路提取稳定能量。经实验验证通过调节电子负载可以为直流负载提供稳定的20V输出电压、9W输出功率。
英文摘要:
      Abstract: The online monitoring and information interconnection of transmission lines is a vital part of building a ubiquitous power Internet of Things. However, it is a difficult point to study the stable supply of energy for monitoring equipment. The use of current transformers provides a promising future for AC transmission line monitoring equipment. The current ofAC transmission lines varies widely, the traditional current transformer is unstable. In order to provide stable output power, this paper proposes an electronic load connected in parallel on the secondary side of the current transformer. The current transformer extracts stable energy from the AC transmission line through impedance matching control. It has been experimentally verified that a regulated 20V output voltage and 9W output power can be provided for a DC load by adjusting the electronic load.
