目前在电力物联网蓬勃发展下,各种传感器终端设备及小型无线基站组成的无线传感网络成为了输电电力物联网感知层的重要组成部分。然而,户外输电线路中的分布式传感节点的连续可靠供电是目前需要重点解决的问题,其中环境微能量采集技术为输电线路传感节点的自驱动供电提供了一种有效解决思路。为解决输电线路分布式监测节点在户外环境下的连续供电问题,本文面向输电线路周围风能与导线微风振动能,设计了一种基于悬挂防振结构的电磁-压电复合取能系统。通过将风杯悬挂结构与导线防振结构相集成,应用风力驱动的电磁取能单元与振动驱动的减振压电取能单元,用于联合收集风能与线路振动能,并具有减振功能,进一步提出具有欠压锁定功能的电源管理策略,以提供面向无线传感节点的标准化直流输出,与传统的整流充电供能方式相比,该电能管理电路的功耗降低了94.7%,可实现对传感器节点的高效持续供电。本文设计的电磁-压电复合能量采集系统为解决输电线路在线监测传感节点的绿色、持续、可靠供电提供了全新的解决思路。
At present
with the vigorous development of power Internet of Things
wireless sensor networks composed of various sensor terminal devices and small wireless base stations have become an important part of the perception layer of power transmission Internet of things. However
the continuous and reliable power supply of distributed sensor nodes in outdoor transmission lines is a key problem that needs to be solved at present
and the environmental micro-energy acquisition technology provides an effective solution for the self-driven power supply of sensor nodes in transmission lines. To address the continuous power supply of distributed monitoring nodes for transmission lines in outdoor environments
this paper designs an electromagnetic-piezoelectric hybrid energy-harvesting system based on a suspended antivibration structure
targeting both the ambient wind energy around transmission lines and the conductor’s micro-aeolian vibration energy. By integrating the suspension structure of the wind cup with the anti-vibration structure of the wire
a wind-driven electromagnetic power generation unit and a vibration-driven vibration damping piezoelectric power generation unit are designed. Furthermore
a power management strategy with undervoltage locking function is proposed to provide standardized DC output for wireless sensor nodes. Compared with the traditional rectifier charging power supply mode
the power management circuit reduces the power consumption by 94.7%
which can realize efficient and continuous power supply for sensor nodes. The electromagnetic-piezoelectric composite energy acquisition system designed in this paper provides a new solution to solve the problem of green
continuous and reliable power supply of online monitoring sensor nodes of transmission lines.
