Products Description

YTPQC-AHF Active Harmonic Filter is a perfect comprehensive solution to power quality problems with power grid such as harmonic wave, reactive power, and three-phase load unbalance. YTPQC-AHF Active Harmonic Filter is connected in parallel in power grid, to detect the harmonic wave in power grid in real time, generate the reverse-phase compensation current through the converter, and dynamically filter the harmonic wave in power grid. The operation of YTPQC-AHF is unaffected by power grid structure and load type, and it will not produce harmonic oscillation with the system, thus perfectly realizing harmonic wave control of various loads. YTPQC-AHF Active Filter can also realize dynamic reactive compensation, and control the capacitor switching, to improve the power factor of power grid. Meanwhile, YTPQC-AHF Active Harmonic Filter has the function of controlling the three-phase load current unbalance, thus comprehensively solving various power quality problems with power grid.

YTPQC-AHF based on 3-level topology, is an Active Harmonic Filter (AHF) system designed to eliminate harmonic oscillations and reduce costs consequently. YTPQC- AHF is a versatile solution, easily tailored to deliver power factor improvement, voltage variation control, flicker mitigation and load balancing functionality, and highly improved power quality in networks while reducing harmonic pollution.

YTPQC Active Harmonic Filter has a advanced modular design. Usually YTPQC-AHF 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.

According to the mounting type, YTPQC-AHF can be divided into Rack Modular, Wall-mounted and free landing AHF.
