Self-Protection Module for Power Line Communication Node in DC Micro Grid System

The protection is one of the major technical challenge to increase the extension of DC power networks. Our research proposes a new concept of three-layer self-protection module for DC micro grid nodes. This module allows the node to react when a problem happens by promptly sensing the line, using sensor and receiving an emergency signal from other nodes. A prototype has been build using a common MOSFET as the switch and testing with resistor as load on low voltage DC micro grid system.
