Abstract

A laser fiber power supply working method based on power adaptive feedback adopts a laser fiber power supply system, the laser fiber power supply system comprises a laser, a super capacitor energy storage module, a photovoltaic module and a first microcontroller, and the photovoltaic module is suitable for supplying power to a sensing node. When the laser optical fiber power supply system is in a sensing node power supply mode, the first microcontroller executes loop feedback control on the incident laser power transmitted to the photovoltaic module by the laser based on the output power of the photovoltaic module, the power requirement of the sensing node and the working voltage of the super capacitor energy storage module, and the charging process of the photovoltaic module to the super-capacitor energy storage module and the discharging process of the super-capacitor energy storage module to the sensing node are controlled. The laser fiber power supply working method based on power adaptive feedback can improve the long-term reliability of the laser fiber power supply system.

Description

technical field [0001] The invention relates to the technical field of laser fiber power supply, in particular to a laser fiber power supply working method based on power adaptive feedback. Background technique [0002] Laser fiber powering is the preferred solution for sensing node power in high voltage (HV) environments. The reason for choosing a laser fiber power supply system instead of a conventional power supply is the requirements for electrical isolation, lightning protection, spark protection, anti-electromagnetic interference, weight reduction, and corrosion resistance. Optical power requirements for laser-fiber-powered systems for sensing applications in high-voltage environments typically range from a few watts to tens of watts, much higher than those used in optical communications. [0003] On-line monitoring of the status of key high-voltage equipment is an important means to detect abnormalities early and take remedial measures to ensure reliable operation of...
