PLC Network Integrity Solution

Assuring that the power line has not been altered or tampered with in an unauthorized manner is key for maintaining the integrity of Power Line Communication (PLC) networks. This chapter introduces a PLC topology change detection technique that can identify modifications in the power grid physical network. Experimental results are presented to confirm the quality and viability of the proposed approach, showing excellent detection accuracy, even at high PLC noise levels. This Channel Impulse Response (CIR)-only-based solution for topology detection presents an efficient PLC network integrity scheme that cannot only detect but also identify the specific altered links.
