The fast development of the new energy industry has driven rapid growth of the battery production industry. In the battery manufacturing process,
The three-phase bridge rectifier is widely used as a charging device, especially in the battery formation process when the batteries being charged and discharged, generates big amount of harmonic pollution, great harm to the power grid.
Cause transformer temperature rise, resulting in reduced transformer capacity
Detrimental to the power equipment, result in the copper and iron loss increase, with additional temperature rise and motor efficiency reduction
Resonance between harmonic and capacitors in reactive power compensation devices, amplifies harmonic causes capacitor bank temperature rise
Resonance between harmonic and capacitors in reactive power compensation devices, amplifies harmonic causes capacitor bank temperature rise
APF is recommended to used for both power factor correction and harmonic filtering
APF to be installed close to the low voltage load.
User case: One batter manufacturing plant, installed APF system. Power factor was 0.855 on the 10KV side before installation, it was improved to 0.947 after installation. Overall energy bill saving >6%. ROI less than 14 months.
