地面合成电场是评价特高压直流输电线路下电磁环境的重要参数之一,因而受到人们广泛关注。研究了一种基于Zigbee技术的特高压直流输电线路下地面合成电场测量系统,并且重点研究了复杂环境下该系统的网络拓扑和性能。实验结果表明,该系统能在复杂环境下正常工作,且操作简单、稳定性好。
Total electric field at ground level is one important parameters to assess electromagnetic environment under ultra high voltage DC (UHVDC) transmission line, therefore special attentions are paid to it. Based on Zighee technology, a system to measure total electric field at ground level under UHVDC transmission line is developed, and the network topology and performances of the developed measuring system in complicated surrounding environment are researched in detail. Experimental results show that the developed measuring system can operate normally and steadily in complex environment and is easy to use.
