Yuav ua li cas xam cov kev them nyiaj kho kom muaj peev xwm

Hluav taws xob yog hluav taws xob yog cov kws tshaj lij kev lag luam ntawm cov khoom siv hluav taws xob tsawg tiv thaiv lub zog thiab cov khoom siv sib tua. Peb los rau hauv kev sib cuag nrog ntau tus neeg siv khoom nrog kev them hluav taws xob cuam tshuam. Lawv cov xwm txheej tuaj yeem sib faib ua ob hom. Thawj hom yog cov phiaj xwm tshiab uas muaj kiag li tsis muaj kev siv fais fab nyiaj txiag. Qhov thib ob yog kev kho cov phiaj xwm kev kho lub zog uas tsis tau ua haujlwm, tab sis yog vim muaj ntau yam, tab sis kho tau rau cov phiaj xwm uas twb muaj lawm.

Rau cov haujlwm tshiab, hauv cov lus yooj yooj yim, lub zog muaj zog yam tsis muaj kev siv hluav taws xob tsis tau paub. Feem ntau hais lus, siv txoj kev ib qho yog tsis yooj yim sua kom suav vim hais tias ib tug paub tias yog ploj lawm. Yog li ntawd, peb yuav tsum qhia ib qho nqi empirical. Rau cov neeg siv hloov hluav taws xob tau zoo dua qub, lub chaw siv hluav taws xob muaj zog feem ntau yog cov khoom siv lub zog ntawm {}}. 9 lossis siab dua yuav tsis raug ntsuas. Txawm li cas los xij, rau tib 630kW Transformer, lub nra tiag tiag ntawm tus neeg siv yog txawv, thiab cov khoom siv nyiaj txiag reactive kuj sib txawv. Feem ntau, peb noj 30-40% ntawm kev muaj peev xwm transformer.

 

Kev them nyiaj ntxiv rau kev them nyiaj kom raug muab xam tau li cas?

Txhawm rau laij cov peev txheej ntawm cov khoom siv nyiaj kho mob hluav taws xob, peb qhov kev ntsuas yog feem ntau yog xav tau rau kev suav;
(1) Lub zog siv hluav taws xob ua ntej cov khoom siv nyiaj kho mob hluav taws xob tsis nruab; Nws yog sawv cev los ntawm "Cosφ1"
(2) Lub zog xav tau kom tau nce ntxiv; Nws yog sawv cev los ntawm "Cosal2"
(3) Lub zog nquag ntawm cov neeg hloov pauv hloov pauv ntawm cov neeg yuav khoom hloov pauv; Nws yog sawv cev los ntawm "p" kev xam cov mis

Hauv cov qauv:
P: Lub zog nquag;
Q1: cov fais fab ua ntej lub zog hluav taws xob ua haujlwm tau nruab;
Q2: Lub zog reactive tom qab Parallel REverive Fais fab nyiaj tau los yog hauv kev ua haujlwm;
QJ: Cov hwj chim uas yuav tsum tau them nyiaj;

Rooj plaub:
Xws li cov neeg hloov hluav taws xob hloov hluav taws xob ntawm tus neeg siv hluav taws xob tau tsim nyog yog 63 {}, thiab lub zog siv hluav taws xob hloov kho hluav taws xob raug ntsuas. Tam sim no, nws yog ib qho tsim nyog los nce lub zog muaj zog rau ib puag ncig 0.9. Npaum li cas ib qho kev them nyiaj reactive hluav taws xob yuav tsum tau teeb tsa?

Lub hom phiaj:Cov kev suav no txiav txim siab cov kev them nyiaj fais fab (QCQC) xav tau los txhim kho lub zog hluav taws xob los ntawm cos⁡φ {}}. 9Cosφ2 =0. 9.

Chav nyob:

Pp (nquag siv zog) hauvkw,

QQ (REQUE FAIS) hauvlub Kvar,

SS (pom meej lub hwj chim) hauvKVA.

Qhov tshwm sim:Lub capactratory bank ntawm kwv yees li321 Kvaryuav tsum tau them nyiaj.

 

Cov txee hluav taws xob tsawg-voltage reactive reluctive fais fab txee yog ib qho cuab yeej siv los them rau cov hwj huam rov qab los ntawm inductive thauj khoom. Cov cuab yeej no ua si lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog hluav taws xob ntawm lub neej, ua kom muaj zog ntawm cov khoom siv hluav taws xob, thiab txo peev hluav taws xob hloov pauv.
