How to improve power quality in variable-frequency drives for scraper conveyors?
🔌 Challenge:
Modern mines are actively implementing VFDs for scraper conveyors. However, this introduces voltage and current distortions, reducing energy efficiency and safety.
📊 Research:
Scientists from MISIS analyzed harmonic distortions in MPDS and evaluated the effectiveness of HFs, reactors, and SFs.
🔹 Key Findings:
✔️ HFs and reactors reduce harmonics upstream of the FC by 70–90%.
✔️ SFs mitigate distortions downstream of the FC but require precise tuning.
✔️ Harmonics in leakage circuits (especially 3rd, 5th, 7th) impact RCDs and personnel safety.
✔️ Combined use of HFs, reactors, and SFs delivers optimal results but needs technical-economic justification.
⚠️ Risks:
Higher harmonics in leakage circuits pose safety hazards and disrupt protective devices.
💡 Recommendations:
1️⃣ Deploy HFs and reactors to suppress harmonics upstream of the FC.
2️⃣ Carefully select SF parameters.
3️⃣ Account for harmonics when configuring RCDs.
4️⃣ Implement real-time power quality monitoring.
📌 Conclusion:
Enhancing power quality in VFD-driven scraper conveyors demands a holistic approach and adaptive protection systems.
