Power Quality Management
Harmonic control and reactive power compensation
Reactors are mainly used in low-voltage power distribution systems, connected in series with compensation capacitor banks. By utilizing inductance characteristics, they suppress high-order harmonic currents in the power grid, prevent harmonic amplification from impacting capacitors and power distribution equipment, and effectively reduce the grid harmonic distortion rate to improve power quality. Meanwhile, through reasonable matching with capacitor banks, they achieve accurate reactive power compensation, significantly enhance the system power factor, reduce reactive power loss and voltage fluctuations, and improve grid operation efficiency. They also avoid equipment damage caused by resonant overvoltage and overcurrent, serving as key components to ensure safe and stable grid operation in industrial power distribution, reactive power compensation and harmonic control applications.
Harmonic Mitigation
With precise matching of 6%–14% reactance rates, it suppresses characteristic harmonics including the 5th, 7th, 11th and 13th orders, and avoids harmonic amplification caused by parallel resonance.
Reactive Power Compensation
Working in conjunction with capacitor banks, it accurately compensates inductive reactive power, lifts the power factor to above 0.95, and reduces power factor adjustment fines.
Equipment Protection
It limits capacitor switching inrush current to less than 20 times the rated current, prevents overcurrent damage, and extends equipment service life.
System Optimization
It improves voltage waveform, lowers transformer losses, increases power utilization efficiency, and guarantees stable operation of precision equipment.
Protect the frequency converter
Input and output reactors are key supporting components for protecting frequency converters in power circuits. Connected in series with the input and output loops of frequency converters, they suppress grid surges, harmonic interference and voltage fluctuations through the current-limiting inductance characteristics, preventing damage to core components of frequency converters caused by overvoltage and overcurrent impacts.
Specific functions:
1）Suppress grid harmonics and high-frequency interference to reduce losses in the rectifier units of frequency converters;
2）Limit the impulse current during the start-stop and sudden load changes of the frequency converter, protecting power devices such as IGBTs;
3）Reduce voltage spikes and dv/dt stress at the motor terminal to extend the insulation life of motors;
4）Improve system power factor and enhance the operation stability of variable frequency drive systems.
