Distinguishing Active Harmonic Lim Los Ntawm Lwm Cov Lim Lim

Nyob rau hauv lub tshav pob ntawm harmonic mitigation nyob rau hauv lub hwj chim systems, muaj ntau yam technical le caag thiab ntaus ntawv muaj. Active harmonic filters, vim lawv qhov tshwj xeeb tswj mechanism thiab kev ua tau zoo, yog qhov sib txawv ntawm cov khoom siv ib txwm muaj thiab zoo sib xws. Kev nthuav qhia qhov sib txawv no pab xaiv cov kev daws teeb meem tsim nyog raws li qhov xav tau ntawm engineering tiag tiag, ua tiav qhov kev ua kom zoo ntawm lub zog zoo.

 

Piv rau cov lim dej tsis sib haum xeeb, qhov sib txawv tseem ceeb nyob hauv lawv txoj cai them nyiaj thiab kev hloov pauv. Passive filters muaj xws li passive Cheebtsam xws li reactors, capacitors, thiab resistors. Lawv cia siab rau LC resonant circuits los tsim qis -impedance txoj hauv kev rau qee zaus harmonics, bypassing los yog absorbing lawv. Txawm hais tias yooj yim hauv cov qauv thiab tus nqi qis, lawv tsuas tuaj yeem txo cov kev sib haum xeeb hauv cov kab hluav taws xob ruaj khov thiab muaj kev cuam tshuam rau cov kev hloov pauv hauv kab sib chaws impedance, uas ua rau muaj kev sib luag los yog series resonance thiab qhia txog cov teeb meem hluav taws xob tshiab. Active harmonic filters, ntawm qhov tod tes, yog raws li active tswj technology. Lawv tau txais cov ntaub ntawv sib haum xeeb hauv lub sijhawm tiag tiag los ntawm chav kuaj xyuas thiab txhaj cov nyiaj rov qab rau hauv qhov system ntawm lub inverter Circuit Court, ua tiav synchronous tshem tawm ntawm qhov dav -bandwidth, ntau- zaus harmonics yam tsis muaj kev pheej hmoo ntawm resonance. Lawv adaptability thiab txo qhov tseeb yog qhov zoo tshaj rau cov kev daws teeb meem passive.

 

Piv rau hybrid harmonic lim, ob qho tib si active thiab passive harmonic lim integrates active thiab passive Cheebtsam, tab sis lawv txawv nyob rau hauv lawv tus tswv - qhev kev sib raug zoo thiab kev ua tau zoo tsom. Hybrid filters feem ntau yog siv cov khoom passive rau thawj lim, thaum lub active Cheebtsam yog siv los txhim kho cov yam ntxwv ntawm passive ceg los yog nthuav kev tswj ntau yam. Lawv cov nqi thiab qhov loj me poob ntawm cov lim dej tsis huv thiab cov lim dej ntshiab huv. Active harmonic filters, ntawm qhov tod tes, yog raws li active tswj. Tag nrho cov kev them nyiaj sib haum xeeb yog ua tiav los ntawm cov teeb liab tsim tawm, tsis muaj kev vam khom cov ceg ntoo. Yog li ntawd, lawv muaj qhov zoo ntawm cov lus teb ceev ceev, tswj kev yoog raws, thiab kev sib raug zoo, ua rau lawv tshwj xeeb tshaj yog haum rau cov xwm txheej uas muaj qhov sib txawv loj thiab cov kev sib raug zoo sib haum xeeb.

 

Lawv kuj txawv ntawm static var generators (SVG) hauv lawv cov kev pab them nqi kho mob. SVGs feem ntau yog tsom rau cov nyiaj them rov qab muaj zog. Thaum lawv tuaj yeem ua tiav qee qhov kev sib haum xeeb los ntawm cov tswv yim tswj tshwj xeeb, lawv cov algorithms thiab kho vajtse tsim tsis tau tshwj xeeb rau kev tswj hwm kev sib raug zoo, txwv tsis pub lawv muaj peev xwm them nyiaj thiab raug rau siab dua harmonics. Active harmonic filters, txawm li cas los xij, tsom mus rau kev sib raug zoo ntawm kev sib raug zoo, ib txhij ua tiav cov nyiaj them rov qab muaj zog thiab peb - theem tsis txaus kho, thiab tshwj xeeb tshaj yog nyob rau hauv harmonic dynamic nrhiav thiab them nyiaj raug.

 

Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm kev teb ceev thiab kev cia siab rau kev khiav hauj lwm, active harmonic filters muaj millisecond -level dynamic teb, cia lawv hloov mus rau load hloov sai; passive filters raug txwv los ntawm cov khoom tsis sib xws, cov ntxaij lim dej hybrid poob qhov chaw nyob nruab nrab ntawm, thaum SVG, txawm tias ceev- teb, tsis yog lub hom phiaj kev sib haum xeeb. Hais txog kev ntseeg tau ntawm kev ua haujlwm, cov lim dej tsis muaj zog muaj zog dhau qhov ua siab ntev tab sis muaj kev cuam tshuam rau resonance, thaum cov lim dej sib haum xeeb tsis txhob muaj kev cuam tshuam los ntawm kev tswj xyuas ntse, nrog kev ntseeg siab ntawm kev saib xyuas lub zog hluav taws xob thiab cov tshuab cua txias.

 

Zuag qhia tag nrho, cov lim dej sib xyaw ua haujlwm sib txawv ntawm cov khoom siv tsis zoo thiab qee cov kev daws teeb meem sib xyaw hauv cov ntsiab lus ntawm kev txo qis, kev pab cuam spectrum, kev ua haujlwm zoo, thiab ntau yam - kev sib koom ua ke. Lawv kuj ua tau zoo tshaj SVG, uas feem ntau tsom rau cov nyiaj them rov qab muaj zog, hauv kev txo qis kev sib haum xeeb tshwj xeeb, ua rau lawv nyiam siv tshuab rau cov ntawv thov uas muaj lub zog zoo.
