All in One Active Haronic Filering Specialized in Hotel Application (PF, Harmonic, unbalance)

    A large number of high-tech operations have used a large number of variable frequency speed control devices in the entire production process from spinning to weaving, which has led to more and more power quality problems and harmonics in power systems, and has caused a lot of disadvantages to the production line. Causes the production line to have nylon chips, sizing machines, yarn doubling machines, automatic winders, combers, carding equipment, and tampers to use the automatic control equipment and power electronics to prevent the heating temperature from being controlled, resulting in serious product quality The decline will cause huge economic losses to the company; the electrical components such as transformers and busbars in the power distribution room will be severely hotted, causing great potential risks.Introduction  The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1.    Our APF equipment is module structure,there are two types Wall Mounted and cabient mounted.The Wall Mounted type is preferred to be used in equipment improvement which is very conveninet to install.  The Sanhe Modular Active Harmonic Filter series are suitable for applications of all types, providing harmonic mitigation, load balancing and step-less reactive power compensation for inductive and capacitor loads.    Main ParameterRated voltage: 0.4kV,0.69kVFrequency: 45Hz ~ 63HzThree level topology and high efficiency up to 97%Filtering capacity: THDi (current distortion rate) < 5%Response time: less than 15msCommunication interface: RS485, network port,Wi-FiFeatureHarmonic, dynamic reactive power and imbalance compensation mode available.Compact and reasonable structure, flexible installation.Combination of FFT and instantaneous power algorithm available.3DSP+CPLD control mode2nd ~51th harmonic can be compensated simultaneously, and specific harmonic orders are programmable.Harmonic compensation, reactive power compensation and three-phase unbalance compensation.Communication protocol: the power of the general protocol, Modbus protocol, TCP/IPFault alarm and recording function, can be as much as 500 alarm records.With all kinds of complete and effective protection measures, such as over-voltage protection, under voltage protection, short circuit protection, inverter bridge reverse protection, compensation protection etc.Protection grade: IP20, the remaining IP grade can be customizedHuman-friendly LCD displaying all voltage, current and harmonic data in numerical, waveform and spectrum.

The active filters analyze the line current harmonics drawn by the loads and generate a compensation current at the opposite phase angle, thereby "neutralizing" the harmonic currents.Optimized harmonics filtering efficiencySelection of every harmonic to the 50th order /Filter up to 50th harmonics simultaneously /Harmonic filtering levels [%] for each specific harmonic order can be pre-configured / Resonance protection by means of pre-configuring harmonic filtering levels for the potential resonance zones / Harmonic attenuation > 97%Compact high performanceUltra-compact, space economical / User-friendly, ease of commissioning / Parallel capability of modular AHF units with respect to network requirements / Available in rack, wall mounting designs and complete enclosure typeEnhanced Reliability LevelsIncorporates intelligent FFT calculation method:Provides "real time sensing" of network impedance for progressive harmonics compensation to achieving system stabilityAdvanced control algorithm for resonance protectionIn event of parallel resonance with load variations, the APF is designed to
