The complete set of active power filter equipment, which adopts the most scientific, cutting-edge and effective intelligent control technology for harmonic control in the world, is paralleled to both sides of the general distribution cabinet of the governance object, playing a very good role in cleaning the current quality problem of the governed object. It perfectly solves the complex power quality problem with perfect intelligent control, high efficiency, fast dynamic response, stable and reliable operation state, Let the perfect power quality show in front of you.
KSVG-APF can dynamically and accurately compensate harmonics and reactive power that vary in size and frequency. It can filter multiple and higher harmonics at the same time with a filtering rate of more than 95% without causing resonance.
KSVG-APF adopts fully controlled power electronic components to generate high-order current with higher switching frequency (IGBT) to offset harmonic current.
Active filter has the following advantages:
● The predictive control method of harmonic current is adopted, with fast response speed (5ms), strong filtering ability and small operation loss. It can fully meet the requirements of different working conditions;
● All harmonics or multiple selected harmonics can be filtered simultaneously and dynamically in real time; The vector screening technology is adopted to selectively compensate the 2nd to 50th harmonics;
● Dynamically compensate fundamental reactive power while filtering harmonic, improve power factor and avoid reactive power reverse transmission;
● Good safety, no resonance or voltage amplification (access reactor is designed), active filter intelligent device can automatically limit the output current, and the device will never overload to ensure safe and reliable operation of the device;
● Unbalance can be compensated to avoid the impact of negative sequence current on power grid and electrical equipment;
● Intelligent starting system, one key grid connection;
● The electrical part is connected by H-bridge: the active power filter decomposes the system line voltage into phase voltage, which greatly improves the reliability of the equipment. The output current waveform is smooth, the device loss is low, and the adaptive control algorithm can adapt to any system impedance change;
● Unique 3H bridge structure: each phase is independently controlled, which improves the controllability of the whole system. For example, when the harmonic current of one phase is too high for compensation, the compensation effect of the other two phases will not be affected. At the same time, the 3H bridge type has a good heat dissipation effect. It uses A, B, and C phases for heat dissipation, and each phase reactor and IGBT are equipped with special heat dissipation devices.
