Power Quality Problems
With the in-depth application of power electronic technology, the automation of the petrochemical industry has been continuously improved, and the nature of the load has also undergone qualitative changes. The increase of nonlinear and impact loads has brought about voltage flicker, three-phase imbalance, and excessive reactive power consumption. , harmonics and a series of power quality problems, affecting the safe operation of the power grid and reducing production capacity.
The main harmonic sources in the petrochemical industry include frequency conversion speed regulation devices of pumps, uninterruptible power supply devices, motor soft start equipment, and new lighting tools (energy-saving lamps, fluorescent lamps with electronic ballasts, etc.).
Hazards and Influence
YT Power Quality Solutions
The petrochemical industry has a long production line, a wide range of fields, a high degree of automation, and complex devices are related. Due to the needs of production, there are a large number of rapidly changing shock loads and nonlinear loads. According to the current situation of harmonics in the power system of petrochemical industry, the best solution is to use Active Harmonic Filter technology. The Active Harmonic Filter device adopts advanced power electronic technology to detect the harmonics in the power grid in real time, and generates an inverse compensation current through the converter to dynamically filter out the harmonics in the power grid.
