中文摘要:

电力电缆的局部放电监测是保证电缆安全运行的重要技术手段。然而,传统有源有线的局部放电在线监测方法难以适用于敷设结构复杂、分布区域广且对成本较为敏感的电缆网络。针对此问题,本文设计了一种基于物联网技术的低功耗分布式电缆局部放电在线监测系统。首先,本文在考虑传感网络可扩展性和可接入性基础上,设计了电缆局部放电监测物联网络的总体框架；其次,为满足传感器节点低功耗、长续航的要求,对高频电流传感器、低功耗信号处理和电源管理、数据通信等物联传感网络基本要素进行了优化设计；最终,根据上述研究实现了基于物联网的电力电缆的局部放电分布式监测系统的设计与应用。

英文摘要:

Partial discharge monitoring of power cables is an important technical means to ensure the safe operation of cables. However, the traditional cable monitoring method is difficult to apply to the cable network system with complex feeder structure, wide distribution area and more cost-sensitive. To solve this problem, a cable insulation state sensing technology based on Internet of Things (IOT) technology is proposed in this paper. Firstly, considering scalability and accessibility, the overall framework of wireless sensor network for cable partial discharge monitoring is designed; secondly, the technical requirements of sensor nodes, low power management, data communication and other basic units of Internet of Things sensor network are analyzed; finally, based on the above research, it is realized. Distributed IoT monitoring for high frequency current of partial discharge in power cables. The system has broad application prospects in the on-line monitoring of partial discharge in cables
