PRODUCT INTRODUCTION: WT-APF active
power filter (APF) is a new type of power electronic device used to
dynamically suppress harmonics and compensate reactive power. It
detects the load current with sampling circuit, extracts the
harmonic component in the load current through internal DSP
calculation, and drives IGBT, The control inverter generates a
harmonic current which is equal to the harmonic current of the load
and in the opposite direction and injects into the power grid to
achieve the purpose of filtering. According to the same principle,
APF can also compensate the negative sequence current component of
asymmetric three-phase circuit, to realize the three-phase
unbalance compensation and reactive power compensation.
Comprehensive functions: intelligent harmonic
filtering, dynamic reactive power compensation and three-phase load
balancing can be realized at the same time
Excellent performance: with nearly perfect harmonic
filtering effect and continuous dynamic reactive power
compensation, the power factor is increased to more than 0.95 to
ensure load balance and safe operation of equipment
Advanced technology: continuous, dynamic tracking
compensation, 40us response to load change, 10ms compensation. The
filtering performance is not affected by the system impedance. The
harmonic compensation characteristics are not affected by the
frequency change of the power grid, and the compensation ability is
not limited by the grid voltage.MODEL DESCRIPTION:SPECIFICATION
