Kev hloov kho ntawm lub voj voog tam sim no thiab lub voj nrawm nrawm hauv cov tsav tsheb sib txawv yog qhov tseem ceeb ntawm kev tswj tsav. Cov hauv qab no muab cov lus piav qhia ntxaws txog kev hloov kho rau ob lub voj voog no:
I. Txoj Kev Loop Tuning tam sim no
Lub voj tam sim no ua haujlwm raws li lub voj sab hauv ntawm VFD, feem ntau cuam tshuam cov zis tam sim no. Cov zis tam sim no txiav txim siab torque, uas nyob rau hauv lem dictates acceleration. Yog li ntawd, tam sim no voj tuning ncaj qha cuam tshuam qhov kev ua tau zoo ntawm VFD.
1. Kev Txiav Txim Tam Sim No Loop PID Parameters:
● Cov voj voog tam sim no PID tsis sib xws (Proportional, Integral, Derivative) feem ntau yog preset nyob rau hauv VFD, tab sis tej zaum yuav xav tau zoo -tuning rau tej daim ntawv thov.
● Tus nqi nce (P) txo qhov kev ua yuam kev thiab txhim kho cov lus teb, tab sis cov txiaj ntsig ntau dhau yuav ua rau lub cev oscillation.
● Integral nce (I) tshem tawm qhov yuam kev seem, tab sis qhov muaj nuj nqis ntau dhau yuav ua rau lub cev tsis ruaj khov.
● Qhov kev nce qib derivative (D) hloov kho raws li tus nqi ntawm qhov kev hloov pauv ntawm qhov yuam kev, ua kom lub cev ua haujlwm tau zoo rau cov kev hloov me me.
2. Kho lub voj tam sim no teb ceev:
● Cov lus teb ceev ntawm lub voj tam sim no yuav tsum phim qhov inductance thiab tsis kam ntawm lub cev muaj zog thiab cable los tiv thaiv oscillations hauv lub voj tam sim no.
● Cov lus teb ceev tuaj yeem hloov kho los ntawm kev kho qhov sib npaug thiab sib npaug ntawm cov voj voog tam sim no.
3. Ceev faj:
● Kev saib xyuas tshwj xeeb rau lub voj voog tam sim no yuav tsum tau ua thaum pib, thauj khoom thauj mus los, qis nrawm, hnyav hnyav, lossis overcurrent faults.
● Kev hloov lub voj tam sim no yuav tsum ua raws li lub cev muaj zog thiab cov kab hluav taws xob tiag tiag kom ntseeg tau tias qhov system ruaj khov thiab ua haujlwm tau zoo.
II. Ceev Loop Tuning Methods
Lub voj nrawm yog lub voj sab nraud ntawm lub inverter, feem ntau cuam tshuam cov zis zaus. Kev ruaj ntseg thiab qhov tseeb ntawm qhov tso zis zaus yog qhov tseem ceeb rau kev tswj kev ua haujlwm ntawm lub inverter.
1. Kev txiav txim siab ceev voj PID Parameters:
● Lub voj nrawm feem ntau siv PI (Proportional{0}}Integral) tswj.
● Lub proportional nce (ceev nce) txiav txim siab lub cev muaj zog acceleration thiab deceleration tus nqi, thaum lub integral nce smooths ceev hloov thiab txo overshoot.
2. Kho qhov nrawm nrawm teb nrawm:
● Kev hloov kho lub voj nrawm ntawm qhov sib npaug thiab qhov sib npaug sib npaug hloov nws cov lus teb ceev.
● Ntau dua qhov sib npaug sib npaug nrawm dua tab sis tuaj yeem ua rau overshoot; siab dua ib coefficients txo overshoot tab sis yuav qeeb teb.
3. Kev txiav txim siab:
● Thaum lub sijhawm thauj khoom hloov pauv, xyuas kom ceev ceev rov qab mus rau qhov chaw teeb tsa los ntawm kev kho qhov nrawm nrawm.
● Kev nrawm nrawm nrawm yuav tsum ua qhov tseem ceeb hauv kev ruaj ntseg thiab kev ua haujlwm, kom tsis txhob overshoot thiab oscillations.
III. Integrated Tuning Strategy
1. Kho lub voj tam sim no ua ntej lub voj voog ceev:
● Logically, lub voj tam sim no yuav tsum tau kho ua ntej. Siv lub voj zoo tam sim no ua lub hauv paus rau kev nrawm nrawm txuas ntxiv.
● Tam sim no lub voj tuning yuav tsum suav rau lub cev muaj zog thiab cable inductance / tsis kam tiv thaiv oscillations.
2. Kho raws li daim ntawv thov scenarios tiag tiag:
● Cov kev ntsuas tam sim no thiab nrawm nrawm yuav xav tau kev teeb tsa sib txawv hauv ntau daim ntawv thov.
● Piv txwv li, nce qhov kev faib ua feem kom tsim nyog rau cov xwm txheej uas yuav tsum tau teb sai; nce qhov kev nce qib kom tsim nyog rau cov xwm txheej uas xav tau kev hloov pauv.
3. Ua qhov kev sim thiab kev hloov kho:
● Tom qab kev hloov pauv, ua qhov kev sim ua kom pom tseeb ntawm qhov kev hloov pauv tau zoo.
● Raws li cov txiaj ntsig ntawm kev xeem, ua kom zoo ntxiv -tu kom txog thaum lub kaw lus ruaj khov thiab ua tau raws li qhov yuav tsum tau ua.
Hauv cov ntsiab lus, kho cov voj voog tam sim no thiab lub voj nrawm ntawm VFD yog ib txoj kev nyuaj thiab tseem ceeb. Los ntawm qhov tsim nyog parameter teeb tsa thiab cov tswv yim hloov kho, kev ruaj ntseg thiab kev ua tau zoo ntawm VFD tuaj yeem ua kom tau raws li qhov xav tau ntawm kev siv tswv yim.
