Application background:

Intelligent environmental protection building refers to the use of wind power generation system, photovoltaic power generation system, photovoltaic curtain wall system, car charging station system, health new wind system, daylighting system, shade windows technology, building intelligent system 8 energy saving measures new energy saving building. These new equipment and new technologies need to use a large number of power electronic components, will have a lot of power quality problems:

1), inverter air conditioner, elevator, dimming system, a large number of office equipment, AC charging pile and SCR dimming system will produce 3,5 times, 7 times, 11 times, 13 times and other harmonics. In addition, the lighting capacity of the load is high than the use of single-phase power supply, will cause three harmonics in the zero line, raise the zero voltage, increase the heat and load the zero line, and produce three-phase imbalance, Damage to user equipment.

2), the load is unstable, often three-phase imbalance phenomenon.

Recommended solution:

APF products, close to the harmonic source near the compensation harmonics, to avoid interference with important equipment, improve system capacity and reliability.

Active filter design capacity = operating current * current distortion rate

Note: In order to make the compensation better, generally leave margin, so the calculated capacity multiplied by 1.2 as the final configuration capacity.

Customer benefits:

Power factor safety upgrade, to avoid fine

To avoid system resonance, to protect the capacitor compensator to ensure the stable operation of reactive power compensation.

Effective control of harmonics, to avoid interference with sensitive equipment

Extend the life of power equipment, reduce maintenance costs
