摘要
为了解决特高压直流电流互感器运行期间无法进行校准试验的问题,本文设计了一套基于北斗同步的特高压直流电流互感器现场校准装置。文中首先简述了特高压直流输电系统和北斗同步技术,并在此基础上提出了现场校准方案和溯源方案,给出了设计方案,最后进行了实验验证。结果表明,本文设计的现场校准装置能够有效解决电流互感器现场校准问题,为输电系统的控制、保护和测量提供保障。
In order to solve the problem that UHVDC current transformer can＇t be carry out calibration test during operation, a set of field calibration device for UHVDC current Transformer based on Beidou synchronization is designed. This paper first briefly describes the UHVDC transmission system and the Beidou synchronization technology, and then puts forward the field calibration scheme and the tracing scheme, gives the design scheme, and finally carries on the experiment verification. The results show that the field calibration device designed in this paper can effectively solve the field calibration problem of current Transformer and provide a guarantee for the control, protection and measurement of the transmission system.
