Elecnova SFR-APF medium-low voltage reactive power compensation 3 phase active power filter harmonic is a new type of electronic device for dynamic filtering of harmonic wave and reactive power compensation.
The basic principle of APF is tracking and detecting the harmonic current in the net, and generator an opposite current to counteract the harmonic current, so as to improve the power quality.
*Fully independent intellectual property rights
*Intelligent resonance elimination function and strong adaptability
*Fundamental wave reactive power compensation and unbalance compensation function
*Optional full harmonic compensation or selected-order harmonic compensation;
*Modular design, flexible configuration, multi-machine operation in parallel, easy to expand capacity
*Intelligent frequency conversion control
*Accurately eliminate harmonics, with faster compensation.
Complete Equipment and System Protection
Protection of external electrical faults of equipment, including busbar short-circuit, over-voltage and under-voltage, over-frequency and under-frequency, phase sequence error and current inverted sequence.
Protection of internal faults of equipment, including over-current protectionand IGBT over- heating protection.
Automatic capacity reduction in case that the working environment is out of limit.
Current limit of software and hardware
Resonance avoidance, keeping far away from resonance points of the system automatically
Flexible Application Scheme
The product refers to modular design, with convenient expansion and with parallel connection of l0 modules at most.
There are two kinds of modules, ie. plug-in shelf type or wall: mounting type,adapting to multiple installation environments.
Three -phase three wire is compatible with three -phase four-wire, and there are redundant wiring terminals of N lines to adapt to field environment to the greatest extent.
The CT is flexible in installation position, and it can be installed on both power source side and load side.
Excellent Filtering Performance
The maximum filtering number is 50, and the filtering rate of harmonic wave is . Humanized Human-machine Interaction Experience greater than 97%.
There are multiple optional compensation modes, thus distributing active power filtering, reactive compensation and unbalance current compensation according to needs.
It refers to full-scope reactive compensation.
The complete three-phase unbalance strategy realizes active/reactive/split-phase unbalance compensation.
Tri-level main circuit brings lower power consumption and higher efficiency.
Humanized Human-machine Interaction Experience
The interaction can adopt 7in LCD touch screen.
Through the graphical display interface, the user can clearly get to know system waveform diagrams and harmonic spectrograms before and after compensation, as well as improvement situations of electric energy quality of the system, such as THDi, THDu, effective current value and power factor.
