Load analysis: The petrochemical industry often uses medium and low voltage frequency conversion and speed control drilling rigs, submersible pumps, fans and other refining links such as distillation, cracking, catalysis, hydrogenation, furfural and other production lines (inverters and UPS), polyester chip loads, Coking dump truck and other equipment.

The main harmonic sources of low-voltage power distribution systems in petrochemical enterprises include: variable frequency speed regulation devices for pumps; uninterruptible power supply devices; complete sets of DC power supply equipment for substations; soft starting equipment for motors; new types of lighting (energy-saving lamps, electronic ballasts) The fluorescent lamp of the device) is used to supply power to the particularly important loads in the primary load. These loads include: process control DCS system, computer monitoring system of power distribution system, fire alarm system and factory intelligent information management system.

Recommended solution: IVL-RCS static filter compensation component + IVL-APF active filter.

Recommended solution: In the low-voltage power distribution system, configure IVL-RCS static filter compensation components to compensate for reactive power, and configure IVL-APF active filters to filter out harmonics to achieve the best governance effect.

Eliminate the influence of system harmonics;

reduce consumption and energy saving, reduce production costs;

improve power factor, avoid reactive fines; increase the service life of capacitors;

reduce heat generation of transformers, cables, and motors, increase their service life, and extend the average fault-free operation of equipment Time, reduce the cost of maintenance, repair and replacement of equipment;

eliminate hidden dangers of system resonance, ensure the safety and reliability of the power supply system; stabilize the voltage, reduce the interference of harmonics on the process control system;

ensure the safe and stable operation of important sensitive equipment.
