ZAPF three-phase three-wire Shunt Active Power Filter (APF) Main function: harmonic filter: Real eliminate harmonics generated by nonlinear load current, or eliminate background grid side harmonic currents, reducing system voltage, current distortion. Energy consumption: reduce line loss and transformer losses, improve equipment fever, extended equipment life. Stable system: to eliminate the influence of harmonics on shared network devices, a variety of systems to prevent malfunction due to harmonics, capacitors and other equipment to ensure the safety of investment Baoding harmonic control, improve system security, reliability and stability. Active power filter APF (Active Power Filter, called APF) is a dynamic harmonic suppression, new compensation reactive power electronic devices, it is possible to change the size and frequency of harmonics and change reactive power compensation. Only fixed is called active, as the name suggests the device power supply is needed (for harmonic compensation of the main circuit), the application can overcome the traditional LC filters harmonic suppression and reactive power compensation method disadvantages (traditional Compensation) Germany harmonic control, to achieve a dynamic tracking compensation, and can both complement and supplement harmonic reactive; three-phase circuit instantaneous reactive power theory is the main basis for the development of the theory of APF; APF has parallel and series two, The former multi-use; shunt active filter is mainly governance harmonic current series active filter control voltage problem is mainly caused by harmonics. Active Filter comparison with passive filters, harmonic treatment good hospital treatment effect, can filter out many times and main higher harmonics, it does not cause resonance, but the price is relatively high!
