Active Power Filter
such as harmonics, reactive power and 3 phase load unbalance. which is in parallel to power grid can
detect the harmonic wave in power grid in time,generate the reverse-phase compensation current
through the converter and dynamically filter the harmonic wave in power grid.
The operation of APF is unaffected by multifarious load forms and power grid structures.
And it will not produce harmonic oscillation (resonance) along with the system, thus perfectly
realizing harmonic control under diverse loads. Active Power Filter can fully accomplish dynamic
reactive compensation, control the capacitor switching and ultimately heighten the power factor
of power grid. Meanwhile, APF has the function of controlling the three-phase load current unbalance,
thus comprehensively handling various power quality matters in power grid.

APPLICATIONS:
Active Power Filter reduced harmonic levels results in improved electrical network reliability and reduced operating costs. Nuisance tripping
of protective devices and nuisance clearing of fuses due to harmonic heating effects is greatly reduced.
Overheating of motors, transformers, switchgear and cables is also reduced which increases their life expectancy and reduces maintenance costs.
For new installations, over-sizing of distribution equipment to reduce harmonic susceptibility can be reconsidered.
With the development of social economy and science technology, many textile printing and dyeing enterprises in order to improve the product quality
of transformation technology, large use of VFDs, DC equipment, including ventilation equipment (including frequency conversion fan and air conditioning),
lighting equipment, production equipment (yarn, fine sand, grasp cotton, shaping machine, dyeing cylinder, etc.), produce a large number of 5th,7th order harmonic,
cause harmonic, harmonic pollution, lead to power quality decline.
