Description
Technical field
The present invention relates to a kind of mixed filtering compensation device, specifically a kind of hybrid filtering compensation device, i.e.,：Nothing
The combination of source filter branch module and active filter.
Background technology
At present, making rapid progress with Power Electronic Technique, existing low voltage reactive power compensation equipment is due to structure, work(
Can be single, it is impossible to flexibly change compensation way or increase and decrease compensation capacity.Such as frequency control equipment, variable-frequency motor starting device,
Intermediate frequency furnace, arc welder, home electric, electronic apparatus etc., typically can all cause current-voltage waveform to distort, and high order occur humorous
Ripple.And over a period to come load is increased or decreased some electrical equipments, common compensation not only cannot at any time meet increase
Or the effect of filtering compensation capacity is reduced, and mains by harmonics aberration rate may be caused to increase, severe jamming, pollution electrical network are just
Often operation.
Particularly a part of power-supply device in recent years, because the progressive reactive power of technology has substantially reduction, COS can begin
Be maintained at more than 0.98 eventually, Current harmonic distortion rate between 20-30%, passive filter input when although filter big portion
Subharmonic；But power factor can be also compensates for while harmonic wave is filtered, so as to cause circuit reactive power to cross benefit.This device
Purpose is while ensureing to administer harmonic wave, to solve the problems, such as that reactive power crosses benefit；Install shunt reactor additional before filter circuit
Output inductive reactive power, it is therefore an objective to offset the capacitive reactive power after capacitor input, power factor is only mended after capacitor input.Have
The addition purpose of source filter branch is further to improve the harmonic filtration rate of whole machine.With merely using active filter compared with have
Invest low, the high advantage of reliability.
Active power filtering itself is exactly harmonic source.It relies on power electronic equipment, produces while system harmonicses are detected
One group and system amplitude it is equal, the harmonic wave of opposite in phase vector can so balance out system harmonicses so as to become sine wave
Shape.Active power filtering in addition to filtering harmonic wave, while can be with dynamic compensation reactive power.Its reflection is swift in motion, and filters harmonic wave
More than 95% is can reach, compensating reactive power is careful.But price is high, and capacity is little.Because at present in the world Large Copacity silicon valve technology is also
It is immature, so current common separate unit active filter capacity is less than 600A.Its operational reliability is also not as good as passive filter
Wave apparatus.It is big in capacity at present and generally use where requiring that compensation is careful with the progress of Power Electronic Technique in recent years
Active+without source mixed type, i.e., it is passive to carry out jumbo filtering compensation, it is active to be finely adjusted.Active+passive blended electric power filtering
It is that APF and passive filtering combine, larger capacity part is processed using inactive component and utilizes active technique improvement passive
The compensation effect and dynamic property of part, reaches good compensation purpose jointly；Meanwhile, efficiently reduce the appearance of active part
Amount, with save APF capacity it is excessive and increase cost.

Acquisition module, collection power supply it is in parallel with active power filtering compensating module and passive filter compensating module after with it is non-linear
Load in series.Wherein LC passive filterings compensating module primarily serves the effect of harmonics and reactive compensation；Shunt reactor is connected in parallel on
Major loop effect is to export inductive reactive power to offset the unnecessary reactive power of filter circuit, it is ensured that power factor is only while filtering
Mend；And remaining system after active power filtering compensating module part is compensated pair as if passive filtering compensating module is filtered
Harmonic current, at this moment the harmonic content in system power greatly reduce, therefore, will to the capacity of active power filtering compensating module
Ask not high, and active power filtering module can also play a role in improving to the filtering characteristic that LC passive filterings compensate mould, overcome its easy
The shortcoming of resonance is affected and is easily occurred with electric network impedance by electric network impedance.It is difficult to be disturbed by electric network impedance, each part is independently pacified
Dress, debugging is convenient, be easy to field maintenance to dismantle and change.
