Application background:

Intelligent environmental protection building refers to the use of wind power generation system, photovoltaic power generation system, photoelectric curtain wall system, car charging station system, healthy new wind system, daylight lighting system, shading and heat insulation window technology, building intelligent system and other 8 energy-saving measures of new energy-saving building. These new devices and technologies require the use of a large number of power electronic components, resulting in many power quality issues:

1), inverter air conditioners, elevators, dimming systems, a large number of office equipment, AC charging piles and SCR dimming systems will produce 3, 5, 7, 11, 13 harmonics. In addition, lighting and other capacity accounts for a high proportion of the load using single-phase power supply, will cause the third harmonic superposition in the zero line, raise the zero ground voltage, increase the zero line heating and burden, and produce three-phase imbalance, causing damage to the user equipment.

2), the load is not stable, often appear three-phase imbalance.

Recommended scheme:

Select APF products, close to the harmonic source to compensate harmonics, avoid interference to important equipment, improve system capacity and reliability.

Design Capacity of Active Filter = Operating Current * Current Distortion Rate

Note: In order to make the compensation effect better, there is generally a margin, so the calculation capacity is generally multiplied by 1.2 as the final configuration capacity.

Customer Benefits:

Power factor safety increase, avoid fines

Avoid system resonance, protect the capacitor compensator, and ensure the stable operation of reactive power compensation.

Effectively control harmonics to avoid interference to sensitive equipment

Extend the service life of power equipment and reduce maintenance costs
