Harmonic Filter Solution


Taiyuan Metro Line 2 applies three capacities of active harmonic filter free stand cabinets (SFR-APF4-280/0.4, SFR-APF4-240/0.4, SFR-APF4-120/0.4). SFR-APF series active harmonic filter free stand cabinet is a new type of power electronic device for dynamic harmonic filtering, which can filtering harmonics (both in magnitude and frequency) in real time to overcome the shortcomings of harmonic suppression and reactive power compensation of conventional filters. It can realize the harmonic filtering function and reactive power compensation function of the system, and is widely used in electric power, metallurgy, petroleum, ports, chemical and industrial and mining enterprises.
