Interference Level Detector with PCB HDI Rogowski coil for PLC Narrow-Band Applications

Area of Science:

• Electrical Engineering
• Power Systems Analysis
• Electromagnetic Compatibility

Background:

• Supraharmonic disturbances (1-150 kHz) impact power grid quality and Power Line Communication (PLC) performance.
• Existing measurement techniques may not adequately capture these specific disturbances.
• Assessing PLC effectiveness, especially with technologies like PRIME, requires precise disturbance monitoring.

Purpose of the Study:

• To introduce a novel interference level detector (ILD) for measuring conducted supraharmonic disturbances.
• To evaluate the operational properties and effectiveness of the developed ILD.
• To assess the impact of supraharmonic disturbances on narrow-band PLC, specifically PRIME technology.

Main Methods:

• Detailed presentation of the ILD's structure and principle of operation.
• Experimental validation through tests in a low-voltage network.
• Inclusion of non-linear loads to simulate realistic grid conditions.

Main Results:

• The ILD successfully measures conducted supraharmonic disturbances within the 1-150 kHz range.
• Validation confirmed the ILD's capability to assess narrow-band PLC effectiveness.
• Test results provided insights into network behavior under non-linear load conditions.

Conclusions:

• The developed ILD is a viable tool for monitoring supraharmonic disturbances in power grids.
• The study demonstrates the ILD's utility in evaluating PLC transmission, including PRIME technology.
• Practical conclusions were drawn regarding network performance and disturbance management.
