Elcosine Energia-AHF Active Harmonic Filter
Elcosine Energia Active Harmonic Filter is a perfect and comprehensive solution to the power quality issues of power grid , such as harmonics, reactive power and 3 phase load unbalance. Elcosine Energia 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 Elcosine Energia-AHF 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. Elcosine Energia Active Harmonic Filter can fully accomplish dynamic reactive compensation, control the capacitor switching and ultimately heighten the power factor of power grid. Meanwhile, Elcosine Energia-AHF has the function of controlling the three-phase load current unbalance, thus comprehensively handling various power quality matters in power grid.
Modular Design
Elcosine Energia Active Harmonic Filter has a advanced modular design. Usually Elcosine Energia consists of one or several AHF modules and an optional touched LCD Human Machine Interface. Each AHF module is an independent harmonic filtering system, and users can change the harmonic filtering system rating by adding or removing AHF modules.
Model Description

Elcosine Energia-APF in Textile Industry
Elcosine Energia 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.
The Background
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.

The Power Quality Problem
A company is specialized in the production of non-woven fabric manufacturer, producing a variety of short fiber non-woven cloth, varieties of melt-blown non-woven cloth, synthetic leather non-woven cloth, acupuncture non-woven cloth, propylene non-woven cloth, water absorption pad, filter non-woven cloth, antibacterial cotton, automotive interior materials, oil absorption mat and other non-woven products.
Elcosine Energia-APF in Networks
The industrial load mainly includes carding machine, needle acupuncture machine, non-woven oven, coil machine, etc., which will produce series harmonics in the production process, resulting in the field capacitance compensation cabinet can not work normally.In order to ensure the normal operation of the field capacitors cabinet, the 300A active power filter is installed for harmonic mitigation.
The Technical Performancee
The THDV at site is 5.9%, exceeding the national standard limit of 5%, the THDi is 23.5%, the harmonic current is mainly 3rd, 5th, 7th order harmonics, and also contains a small number of 2nd and 4th even harmonics. After treatment, THDv decreased to 2.2%, the THDi decreased to 2.0%, and the current waveform was also restored to the sinusoidal wave type.
