    摘要:

    物联网(IoT)可以为变电站提供在线监视系统,且可以为电力设备提供更加可靠的维护策略,但给变电站以及高压设备周围的传感器通电是困难且昂贵的。如果监控传感器可以自我维持,则可以显著降低使用成本。在本文中研究了基于能量收集和能量无线传输的自持式无线传感器监控系统。为了优化该系统的性能,提出并分析了两种传感器能量供给技术,旨在以无线方式为监视传感器供电。通过优化系统参数,在仿真中成功实现了可自我维持的无线传感器监控网络,验证了所提出方法的有效性。

    Abstract:

    The Internet of Things (IoT) can provide online monitoring systems for substations, and can provide more reliable maintenance strategies for power equipment, but it is difficult and expensive to energize sensors around substations and high-voltage equipment. If the monitoring sensor can be self-sustained, the cost of use can be significantly reduced. In this paper, a self-contained wireless sensor monitoring system based on energy harvesting and energy wireless transmission is studied. In order to optimize the performance of the system, two sensor energy supply technologies are proposed and analyzed, aiming to supply power to the monitoring sensors in a wireless manner. In order to optimize the performance of the system, two sensor energy supply technologies are proposed and analyzed, and is intended to supply power to the monitoring sensor in wireless mode. By optimizing system parameters, self-maintaining wireless sensor monitoring networks can be successfully implemented in simulation, and the effectiveness of the proposed method is verified.
