Cov kab lus no tsom mus rau cov txheej txheem thiab cov txheej txheem siv los txhim kho lub zog hauv nruab nrab zaus inverter qhov chaw vuam tshuab.Lub zog tseem ceeb yog qhov tseem ceeb uas ntsuas qhov ua tau zoo ntawm kev siv hluav taws xob siv hluav taws xob hauv kev ua haujlwm vuam.Los ntawm kev nkag siab txog cov yam ntxwv cuam tshuam rau lub zog thiab siv cov kev txhim kho tsim nyog, cov tuam ntxhab thiab cov neeg ua haujlwm tuaj yeem txhim kho kev siv hluav taws xob, txo kev siv hluav taws xob, thiab ua kom zoo dua qhov ua tau zoo ntawm cov tshuab vuam tshuab.
- Kev nkag siab txog Lub Hwj Chim Hwj Chim: Lub hwj chim yog qhov ntsuas ntawm qhov sib piv ntawm lub zog tiag tiag (siv rau kev ua haujlwm muaj txiaj ntsig) thiab lub zog pom tseeb (tag nrho lub zog nkag) hauv lub tshuab hluav taws xob.Nws txawv ntawm 0 mus rau 1, nrog rau lub zog ntau dua qhov qhia tau hais tias kev siv hluav taws xob ntau dua.Nyob rau hauv qhov chaw vuam tshuab, ua tiav lub zog loj yog qhov tsim nyog raws li nws txo cov hluav taws xob tsis zoo, txo qis hluav taws xob pov tseg, thiab txhim kho kev ua haujlwm tag nrho.
- Factors Influencing Power Factor: Ob peb yam cuam tshuam rau lub hwj chim hauv nruab nrab zaus inverter chaw vuam tshuab:
a.Capacitive lossis Inductive Loads: Lub xub ntiag ntawm capacitive lossis inductive loads nyob rau hauv lub vuam Circuit Court tuaj yeem ua rau muaj kev lag luam lossis ua rau lub zog ua haujlwm, feem.Hauv qhov chaw vuam, vuam transformer thiab lwm yam khoom siv tuaj yeem ua rau lub zog reactive.
b.Harmonics: Harmonics tsim los ntawm cov khoom tsis-linear, xws li cov khoom siv hluav taws xob hauv inverter, tuaj yeem cuam tshuam lub zog.Cov kev sib raug zoo no ua rau muaj kev siv hluav taws xob ntau ntxiv thiab txo cov khoom siv hluav taws xob.
c.Cov tswv yim tswj: Cov tswv yim tswj tau ua haujlwm hauv lub tshuab vuam lub tshuab inverter tuaj yeem cuam tshuam rau lub zog.Cov txheej txheem kev tswj hwm qib siab uas ua kom zoo zog tuaj yeem siv tau los txhim kho kev ua haujlwm.
- Txoj hauv kev los txhim kho lub zog muaj zog: txhawm rau txhim kho lub zog ntawm qhov nruab nrab zaus inverter qhov chaw vuam tshuab, cov kev ntsuas hauv qab no tuaj yeem siv tau:
a.Fais fab Factor Correction Capacitor: Txhim kho lub hwj chim hloov kho capacitors tuaj yeem them rau lub zog reactive hauv lub cev, ua rau lub zog ntau dua.Cov capacitors no pab sib npaug lub zog reactive thiab txhim kho tag nrho cov system efficiency.
b.Active Filtering: Cov lim dej muaj zog tuaj yeem ua haujlwm los txo cov kev sib txawv ntawm qhov sib txawv los ntawm cov khoom tsis-linear.Cov lim dej dynamically txhaj cov nyiaj them rov qab los tshem tawm cov kev sib haum xeeb, ua rau lub zog nqus dej huv thiab txhim kho lub zog.
c.Inverter Control Optimization: Ua raws li kev tswj hwm algorithms hauv lub inverter tuaj yeem ua kom lub zog zoo dua los ntawm kev txo qis reactive zog noj.Cov txheej txheem xws li pulse-width modulation (PWM) tswj thiab tswj cov tswv yim hloov kho tuaj yeem siv los ua kom tau txais txiaj ntsig zoo zog.
Kev txhim kho lub zog ua haujlwm hauv nruab nrab zaus inverter qhov chaw vuam tshuab yog qhov tseem ceeb rau kev txhim kho lub zog thiab kev ua haujlwm zoo.Los ntawm kev hais txog tej yam xws li lub peev xwm lossis inductive loads, harmonics, thiab tswj cov tswv yim, cov tuam ntxhab thiab cov neeg ua haujlwm tuaj yeem ua tiav lub zog ntau dua.Kev siv lub zog hloov kho capacitors, nquag lim dej, thiab cov txheej txheem tswj kev ua kom zoo dua qub yog cov txheej txheem zoo los txhim kho lub zog ntawm lub zog thiab txo qis zog rov qab poob.Cov kev txhim kho no ua rau txo qis kev siv hluav taws xob, txhim kho kev siv hluav taws xob zoo, thiab cov txheej txheem vuam zoo dua.Los ntawm kev txhawb nqa kev txhim kho kev ntsuas hluav taws xob, qhov chaw vuam kev lag luam tuaj yeem ua rau muaj kev cog qoob loo zoo dua thiab ua haujlwm zoo dua.
