Muaj daim ntawv thov ntawm MCR hom dynamic reactive zog them nyiaj ntaus ntawv

MCR hom dynamic reactive zog them nyiaj ntaus ntawv tuaj yeem siv dav hauv cov teb hauv qab no.

1 Fais System

1) Ordinary substation. Los ntawm kev ntxiv MCR nrog ib lub peev xwm los ntawm lub hauv paus ntawm thawj lub txhab nyiaj capacitor, kev tswj hwm kev ua haujlwm tsis tu ncua ntawm lub zog reactive hauv lub substation yog pom tau hais tias, qhov kev txiav txim tsis tu ncua ntawm Circuit Court breakers yog zam, kev siv tus nqi ntawm cov capacitors zoo heev, thiab cov fais fab xwm txheej yog ho txhim kho.

2) hub substation. Los ntawm kev txhim kho cov khoom siv hluav taws xob reactive uas muaj xws li mcr + fc lim nyob rau hauv lub hub substation, los yog ntxiv MCR nyob rau hauv lub hauv paus ntawm tus thawj FC lim los tsim ib tug reactive hwj chim them nyiaj ntaus ntawv, txhim kho lub stability ntawm lub hwj chim daim phiaj thiab ua rau kom muaj peev xwm kis tau tus mob. txoj kab.

3) Tsawg voltage reactor. Hloov cov hluav taws xob tsawg-voltage reactor ntawm substation rau hauv MCR tsis tsuas yog muaj tag nrho cov haujlwm ntawm lub tshuab hluav taws xob tsawg, tab sis kuj muaj cov haujlwm ntawm cov khoom siv hluav taws xob reactive.

4) Kab reactive zog them nyiaj. Los ntawm qhov tsim nyog piv ntawm lub peev xwm capacitor thiab MCR lub peev xwm, qhov kev txiav txim ntawm lub tshuab nqus tsev contactor tuaj yeem raug zam, kev ntseeg tau thiab kev nyab xeeb ntawm cov cuab yeej tuaj yeem txhim kho, thiab kev pab cuam lub neej ntawm cov cuab yeej siv tau ntev heev.

5) Reactive zog them nyiaj ntawm kev faib transformer. Tsc + mcr thev naus laus zis tau txais kev pom zoo los txhim kho qhov tseeb qhov tseeb (0.2 kvar), txo qis kev hloov pauv zaus, thiab ua kom ntseeg tau tias lub zog hluav taws xob rov ua haujlwm ntawm cov khoom siv hluav taws xob hloov pauv mus txog lub zog loj ntawm 0 99-1, paub qhov tseeb reactive. fais fab configuration txheej muab faib sib npaug.

2 Metallurgical System

Rolling mills thiab hluav taws xob arc rauv yog cov feem ntau raug reactive impulse loads. Siv mcr + fc lim rau dynamic reactive fais fab nyiaj them tuaj yeem txhim kho lub zog zoo, txo qhov kev hloov pauv ntawm qhov hluav taws xob thiab flicker, tshem tawm cov pa phem, txhim kho lub zog zoo, txhim kho kev nyab xeeb ntawm cov khoom siv hluav taws xob, txo cov khoom siv hluav taws xob, thiab txhim kho cov khoom lag luam. zoo.

3 Electrified Railway

Electrified railway txais ib-theem fais fab mov hom. Vim lub randomness ntawm locomotive, lub load ntawm traction substation muaj cov yam ntxwv ntawm ib-theem cuam tshuam load, nrog nquag load fluctuation thiab siab harmonic cov ntsiab lus. Nws yog tsis yooj yim sua kom paub qhov muaj hwj chim loj nyiaj them los ntawm kev siv yooj yim fixed them hom. Yog tias MCR nrog lub peev xwm tsim nyog tau teeb tsa los ntawm lub hauv paus ntawm FC lim Circuit Court nrog lub peev xwm txaus, kev them nyiaj hluav taws xob siab tuaj yeem ua tiav txhua lub sijhawm, kev hloov pauv hluav taws xob tuaj yeem txo qis thiab qhov hluav taws xob zoo tuaj yeem txhim kho.

Cov yam ntxwv ntawm ib-theem load ntawm electrified railway kuj coj teeb meem loj ntawm qhov tsis zoo ib ntus tivthaiv rau nws cov khoom siv hluav taws xob sab saud, thiab tseem ua rau muaj kev tiv thaiv tsis zoo ntawm cov chaw tsim hluav taws xob thiab cov chaw nres tsheb. Los ntawm kev txhim kho mcr + fc cov ntxaij lim dej hauv cov chaw nres tsheb no thiab siv lub tswv yim ntawm theem kev sib cais tswj raws li Steinmetz txoj kev, qhov teeb meem no tuaj yeem daws tau zoo, thiab nws tuaj yeem txuas ncaj qha rau 110 kV fais fab mov system rau kev them nyiaj, tsis muaj peev txheej ntawm intermediate transformers, thaj tsam hauv pem teb yog me dua, thiab cov khoom poob nws tus kheej tuaj yeem raug txo los ntawm ntau dua 70%.
