Harmonic compensation, reactive power compensation, combined harmonic-reactive compensation—multi-function in one unit
- Core Advantages
- Technical Parameter
-
1、More functions, and more modes
Ø Harmonic compensation, reactive power compensation, combined harmonic-reactive compensation—multi-function in one unit;
Ø Segmented harmonic compensation and adjustable reactive compensation ratio;
Ø 7-inch high-resolution Chinese color touchscreen displaying real-time system/device parameters;
2、Comprehensive protection for enhanced system stability
Ø Dual-set RMS/peak auto current limiting algorithm prevents overloads by capping output at 100% when load harmonics exceed capacity;
Ø Robust protections: Overcurrent, overvoltage, undervoltage, overtemperature—ensuring safe, reliable system operation;
3、Advanced control strategy and topology
Ø Enhanced detection based on instantaneous reactive power theory enables real-time harmonic current tracking with fast, precise response;
Ø LCL filter topology prevents high-frequency IGBT switching noise and avoids resonance in all grid conditions;
4、High integration, modularization, and scalability
Ø Compact, lightweight, high-power-density modular design for easy installation and maintenance;
Ø Flexible combinations and parallel configurations meet capacity demands while boosting reliability and serviceability;
Ø Independent air duct design for each module improves heat dissipation and resists environmental dust;5、Advanced user experience
Ø Auto diagnostic and restart functionality: If outages are unrelated to device faults, the system self-diagnoses both external grid and internal conditions before restarting. Ø Up to 3 automatic recoveries within 30 minutes; if unsuccessful, triggers fault alarm to upper-level control system and lights device fault indicator.
