Abstract

The area of high voltage direct current (HVDC) transmission line is very large, so using cable for electric field monitoring system is very inconvenient. Wireless sensor network(WSN) can solve this problem. Compared with the traditional communication network, WSN has the advantages of small volume, high flexibility, strong self-organization. So it's more suitable for the construction of distributed electric field monitoring system which has long distance and high mobility. On the other hand, optical E-field sensors are passive devices and they have such advantages as compact structure, wide-band response and wide measuring range which mechanical sensors lack. A distributed wireless system with optical E-field sensor is designed for collecting and monitoring the electric field under HVDC transmission lines. This measurement system has been used in China's state grid HVDC test base and power transmission projects. Based on the experimental results, this measurement system demonstrates that it can adapt to the complex electromagnetic environment under the transmission lines and can accomplish the accurate, flexible, and stable demands of the electric field measurement.

分布式无线传感器网络电场测量系统

高压直流输电线路面积很大，使用电缆进行电场监测系统非常不方便。无线传感器网络(WSN)可以解决这一问题。与传统通信网络相比，WSN具有体积小、灵活性高、自组织能力强等优点。因此更适合远距离、高机动性的分布式电场监测系统的建设。另一方面，光学电磁场传感器是无源器件，具有结构紧凑、带宽响应宽、测量范围广等机械传感器所不具备的优点。设计了一种带有光学电场传感器的分布式无线系统，用于高压直流输电线路下电场的采集和监测。该测量系统已在中国国网高压直流试验基地和输变电工程中得到应用。实验结果表明，该测量系统能够适应输电线路下复杂的电磁环境，能够实现准确、灵活、稳定的电场测量要求。
