With the application of large number of nonlinear power equipment, large harmonic pollution will be generated in the power system.This nonlinear load is the source of harmonics, most of the harmonic order and harmonic contents of the power system harmonic sources change with load or system. The traditional reactive filter technology has been difficult in meeting the dynamic filtering requirements.KLD-active power filter is a very effective filtering method, it is based on high-speed filter-compensation technology, eliminates all forms of harmonics and can be used in many harmonic pollution conditions, especially for rapidly changing loads. It has the characteristics of fast response, wide filtering range,and high filtering effect and free of influences from system parameters. It is the most ideal filtering product to achieve the purpose of improving electric power quality, reducing power loss and increasing power utilization efficiency and carrying capacity.
product description
The active power filter is in parallel with the harmonic source, and quickly generates the current in the equal size and opposite direction through the real-time detection and tracking of harmonic current generated by the harmonic source load, thus eliminating harmonics to avoid system voltage and current waveforms distortion. The device has an adaptive function that compensates for harmonics of varying frequency and size, and extremely fast response to compensation objects.
Features
Harmonic elimination:Eliminate the harmonic current produced by nonlinear load in the system in real time, reduce the system voltage and electric current distortion rate.
Stability system:Eliminate influence of all kinds of harmonic sources on the common-network equipment, prevent various system malfunctions caused by the harmonics, and ensure that equipment e.g. var compensation can be safely put into operation to improve the safety. reliability and stability of the system.
Energy saving and consumption reduction:Reduce transformer loss and line loss, improve the equipment heating, and extend the service life of equipment.
Wide: The range of harmonics orders that can be filtered is wide ranging 2nd to 71st harmonics;
High: The harmonic filter rate is high. Under rated power, the filtering rate of harmonic current can be up to 97%;
Rapid: The response speed is fast. The full response time of harmonic compensation current is less than 10ms;
Stable: The single-phase dynamic compensation current can be injected to improve the three-phase system imbalance, automatically suppress system resonance, and free of worry from the resonance with the system, and ensure the safe operation of equipment and systems;
Full: The 25A module to 200A module cover full range of active power filter products;
Compensation: Both filtering and var compensation (inductive or capacitive) functions;
Advanced: Intelligent control system with complete functions; the latest intelligent control unit, friendly interface, and easy operation; simultaneously displaying the parameters e.g. voltage,current, load harmonics and equipment output harmonics waveform, amplitude and frequency spectrum; real-time fault record and event record;
Convenient: Simple design selection, and easy installation, operation and maintenance. Easy to expand and redundant design, operate multiple units in parallel;
Reliable:Can be set or maximum 100% current limit output. Ensure long-term stable.operation of the device without worry of equipment overload.
Application areas
The characteristics of high harmonic content, irregular changes, and high displacement power factor on the AC side of large DC motors determine that the use of passive filters in such fields can not achieve satisfactory results. Compared with passive filters,KLD-active power filters feature high controllability and fast responsiveness; can compensate for harmonics of various orders,and compensate for var, and have the characteristics of one machine with multiple functions; reasonable cost performance; filtering characteristics are not affected by system impedance and the danger of resonance with system impedance can be eliminated.
