Multifunctional Protections of YT Active Harmonic Filter and Static Var Generator

YTPQC-AHF Active Harmonic Filter

YTPQC-AHF 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. YTPQC-AHF 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.

YTPQC-SVG Static Var Generator

YTPQC-SVG Static Var Generator detects load current in real time through internal and external CT and analyzes the reactive current of load by TI DSP and FPGA, then generates PWM signal to IGBT inverter(3 Level) to generate inductive or capacitive current and compensate reactive current to realize the target power factor. YTPQC SVG can also compensate phase imbalance.
Compared with the traditional capacitor bank, YTPQC-SVG has the advantages of fast response and high compensation accuracy without under-compensation or over-compensation problems, avoid resonance,etc.
