Lub hom phiaj thiab lub ntsiab lus ntawm cov kev pab cuam lub zog hluav taws xob

Qhov sib npaug ntawm cov khoom siv hluav taws xob reactive yog ib qho tseem ceeb ntawm kev ua haujlwm ruaj khov ntawm lub zog hluav taws xob thiab qhov zoo ntawm lub zog hluav taws xob. Cov khoom siv hluav taws xob reactive hluav taws xob, raws li cov khoom siv hluav taws xob rov qab los ntawm kev saib xyuas thiab tswj cov dej ntws ntawm lub zog ntawm lub sijhawm tiag tiag.

I. Txoj haujlwm ntawm cov kev pab cuam lub zog hluav taws xob

1. Txhim kho lub zog

TusReflective Fwjchim MotaubTshawb nrhiav cov khoom siv hluav taws xob cuam tshuam hauv lub zog hluav taws xob hauv lub sijhawm lossis hloov cov khoom siv hluav taws xob lossis txhim kho lub zog hluav taws xob ntawm cov kab ke.

2. Txo cov kab poob qis

Cov dej ntws ntawm cov hluav taws xob muaj zog hauv cov kab kis tau yuav nce cov kab tam sim no, yog li ua rau muaj kev siv hluav taws xob ntxiv. Cov khoom siv hluav taws xob reactive zog tswj tau zoo txo ​​cov kab kev kis tau zoo thiab txhim kho cov kev faib tawm ntawm cov zog ntawm cov hwj huam.

3. Txhim Kho Hluav Taws Xob Hluav Taws Xob

Qhov tsis txaus ntseeg ntawm cov hwj huam ntawm cov hwj huam tuaj yeem ua rau hluav taws xob hloov pauv hauv lub hwj chim hloov, cuam tshuam rau cov khoom siv hluav taws xob ib txwm muaj. Cov tshuaj tiv thaiv hluav taws xob reactive maub los ruaj khov lub zog voltage thiab txhim kho lub zog zoo los ntawm kev kho lub zog hluav taws xob cov khoom siv.

4. Ncua lub neej ntawm cov khoom siv

Los ntawm kev txo cov dej ntws los ntawm lub zog hluav taws xob, cov hluav taws xob tiv thaiv hluav taws xob tuaj yeem txo cov khoom siv hluav taws xob, thiab tsis muaj peev xwm muab cov khoom siv hluav taws xob, thiab yog li ncua kev pabcuam lub neej ntawm cov khoom siv.

5. Txhawb kev sib koom ua ke ntawm cov peev txheej hluav taws xob

Hauv lub zog hluav taws xob tshiab ntau tiam neeg, xws li cua lub zog thiab lub hnub ci hluav taws xob, cov kev hloov pauv ntawm cov hluav taws xob hnyav yog qhov tseem ceeb. Cov tswj hwm hluav taws xob rov qab muaj zog tuaj yeem teb tau sai sai rau cov phiaj xwm kev sib txuas ntawm lub zog tshiab.

Ii. Ua ua hauj lwm cov ntsiab cai ntawm Resive Fais fab kev tswj hwm

1. Cov ntaub ntawv sau

Cov tswj hwm hluav taws xob rov qab muaj zog muaj peev xwm tiag - lub sijhawm cov ntaub ntawv xws li voltage maub los ntawm voltage transformer (PT) thiab tam sim no. Cov ntaub ntawv no ua lub hauv paus rau cov maub los txiav txim siab - ua.

2. Xam ntawm reactive zog

Tus tswj hwm cov kev siv hluav taws xob cuam tshuam hauv lub hwj chim sib koom ua ke raws li cov ntaub ntawv txuas ntxiv thiab cov ntaub ntawv tam sim no. Feem ntau, tus maub los ua hauj lwm ua haujlwm siab dua, xws li Fast Fourier Hloov chaw thiab txheeb xyuas qhov ntau thiab cov kev taw qhia ntawm lub zog.

TusReflective Fwjchim Motaub, raws li cov cuab yeej tseem ceeb hauv lub zog hluav taws xob, ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog, thiab txhim kho kab kev poob, thiab txhim kho voltage zoo. Nws lub hauv paus kev ua haujlwm yog raws li tiag {1} sijhawm cov ntaub ntawv tau txais, ntau dua ntawm cov tswv yim tswj hwm, thiab ua tiav ntawm kev tswj cov lus txib. Los ntawm kev hloov kho kev hloov kho ntawm cov khoom siv hluav taws xob cuam tshuam, nws ua tiav qhov sib npaug ntawm cov khoom siv hluav taws xob rov qab.
