Distribution Line Monitoring System Based on Internet of Things Technology
Distribution automation is an effective method to realize fault detection and localization. It is not suitable for use in the comprehensive promotion in the distribution network because of the high investment and maintenance requirements. It proposes the monitoring system design principle firstly. The distribution line monitoring system based on internet of things technology is practical and of high scalability. It solves the problems in detection of single phase grounding fault, the terminal power supply and communication network. This system records peak current when zero sequence voltage a communication terminal monitors is greater than a certain value. A variety of power supply by solar energy, lithium battery backup and terminal itself can provide the power supply and wireless communication power supply. The system is suitable and practical for application in the distribution line.
