Cov nquag zaus teeb tsa hom ntawm inverter feem ntau muaj xws li: tus neeg teb xov tooj keyboard teeb tsa, teeb liab sib cuag, teeb tsa analog teeb, teeb liab teeb liab thiab kev sib txuas lus hom teeb tsa. Cov zaus muab cov qauv no muaj lawv tus kheej zoo thiab qhov tsis zoo, yog li lawv yuav tsum tau xaiv thiab teeb tsa raws li qhov xav tau tiag tiag. Lub caij no, ntau zaus muab cov qauv tuaj yeem xaiv tau raws li kev xav tau ntawm kev ua haujlwm thiab hloov chaw.
Tus tswj hom
Cov zis hluav taws xob ntawm qhov hluav taws xob tsawg hluav taws xob ntau zaus hloov dua siab tshiab yog 380 ~ 650V, cov zis hluav taws xob yog 0.75 ~ 400kW, qhov ua haujlwm zaus yog 0 ~ 400Hz, nws lub ntsiab hluav taws xob adopts ac-dc - ac Circuit. Nws txoj kev tswj hom tau dhau los hauv plaub tiam no.
Sinusoidal pulse dav tes taws los piav (SPWM) tswj hom
Nws cov xeeb ceem yog cov tswj Circuit Court qauv yog yooj yim, tus nqi tsawg, cov yam ntxwv ntawm lub zog tawv kuj tseem zoo, tuaj yeem txaus siab xa mus rau qhov kis tau yooj yim cov kev cai ceev tau thov, tau siv dav hauv txhua daim teb ntawm kev lag luam. Txawm li cas los xij, thaum muaj tsawg zaus, vim qhov hluav taws xob tsawg tsim tawm, qhov feem cuam raug cuam tshuam los ntawm qhov hluav taws xob poob ntawm stator tsis kam, uas txo qhov siab tshaj qhov zis tawm. Tsis tas li ntawd, nws cov cuab yeej muaj zog, tom qab txhua qhov, tsis muaj qhov ncaj qha tam sim no lub cev muaj zog, thiab lub zog zoo li qub thiab lub zog loj muaj peev xwm tswj tau qhov kev ua haujlwm tsis txaus siab, thiab qhov kev ua haujlwm ntawm lub cev tsis loj, qhov tswj tau hloov pauv dhau load, torque teb tau qeeb , lub cev muaj zog siv kev siv tsis yog siab, qis nrawm nrog stator tsis kam thiab muaj lub zog ntawm inverter tuag lub sijhawm ua haujlwm thiab kev ua haujlwm degradation, tsis ruaj ntseg. Yog li ntawd, tib neeg tsim tsim vector tswj cov khoom siv hluav taws xob hloov kom ceev tau cov kev cai.
Voltage qhov chaw vector (SVPWM) tswj hom
Nyob rau qhov pom ntawm lub zuag qhia tag nrho cov cim ntawm peb-theem waveform, nws tsim peb-theem kev hloov waveform nyob rau hauv ib lub sijhawm thiab kwv yees qhov zoo tagnrho kev sib hloov tig teb sib nqus ntawm cov tsav huab cua sib txawv rau lub hom phiaj, thiab sab hauv txiav polygon kwv yees lub voj voog. Cov. Tom qab siv rau hauv kev coj ua, nws tau txhim kho, uas yog, kev them nyiaj zaus tau qhia rau kom tshem tawm qhov yuam kev ntawm kev tswj ceev. Cov cawv ntawm stator tsis kam thaum muaj kev ceev qis yog tshem tawm los ntawm cov tswv yim kwv yees ntawm flux linkage amplitude. Cov zis hluav taws xob thiab tam sim no raug kaw lub voj los txhim kho qhov raug qhov ceev thiab ruaj khov. Txawm li cas los xij, muaj ntau txoj hauv kev txuas hauv cov tswj kav thiab tsis muaj kev cai torque tau qhia, yog li ntawd kev ua haujlwm ntawm lub system tsis txhim kho hauv paus.
Vector tswj hom (VC) hom
Vector tswj kuj tsis paub meej zaus ceev ceev cov kev cai, nws yog tus stator tam sim no ntawm asynchronous lub cev muaj zog nyob rau hauv peb-theem system Ia, Ib, Ic, los ntawm peb theem - ob theem kev hloov pauv, sib npaug rau ob theem hluav taws xob kev tswj hwm qhov system, ac tam sim no Ia1Ib1 dua los ntawm nias lub rotor teb-hloov kev sib hloov pauv hloov, qhov sib npaug rau kev sib xyaw ua ke ntawm kev hloov pauv ntawm dc tam sim no Im1, It1 (Im1 yog qhov sib npaug ntawm qhov zoo siab tam sim no ntawm dc lub cev; Nws 1 yog sib npaug ntawm qhov hluav taws xob tam sim no uas yog sib npaug rau lub zog), thiab tom qab ntawd tswj kom muaj nuj nqis ntawm dc lub cev muaj zog tau los ntawm kev ua raws li kev tswj ntawm dc lub cev muaj zog. Hauv qhov tseem ceeb, ac tsav yog sib npaug rau dc lub cev muaj zog, thiab qhov ceev thiab lub cev sib nqus tau tswj tau ntawm nws tus kheej. Ob qho kev sib xyaw ntawm kev sib zog thiab kev sib nqus tau txais los ntawm kev tswj lub rotor flux txuas thiab decomposing stator tam sim no. Tus txheej txheem vector tswj yog ntawm epoch-ua qhov tseem ceeb. Txawm li cas los xij, hauv cov ntawv thov siv, lub rotor flux txuas sib txuas yog qhov nyuaj rau kev soj ntsuam kom raug, cov yam ntxwv ntawm cov txheej txheem tau cuam tshuam loj heev los ntawm lub cev muaj zog, thiab vector kev sib hloov pauv siv nyob rau hauv kev tswj cov txheej txheem ntawm sib npaug dc motor yog txoj, yog li qhov tseeb tswj cov nyhuv yog qhov nyuaj kom ua tiav qhov kev tshawb pom zoo tagnrho.
Kev tswj ntsuas qhov ncaj qha (DTC) hom
Nyob rau xyoo 1985, DePenbrock, tus xibfwb ntawm ruhr tsev kawm ntawv hauv Tebchaws Yelemees, thawj zaug tau thov DTC zaus hloov dua siab tshiab thev naus laus zis. Txog ntau yam, qhov thev naus laus no daws tau qhov tsis txaus kev tiv thaiv vector, thiab nthuav dav nrog lub tswv yim tswj tshiab, cov qauv tsim qauv yooj yim thiab kev ua tau zoo heev thiab zoo li qub. Cov thev naus laus zis tau ua tiav zoo rau lub siab zog ac kis ntawm hluav taws xob locomotive traction. Kev tswj ntsuas qhov ncaj qha (DTC) ncaj qha tsom xam cov qauv lej ntawm ac lub cev hauv lub stator coordinate system thiab tswj cov khoom sib txuas sib nqus thiab lub zog ntawm lub cev muaj zog. Nws tsis xav tau lub ac tsav kom sib npaug nrog lub dc motor, yog li nws txuag tau ntau qhov kev suav nyuaj hauv qhov kev sib hloov vector. Nws tsis tas yuav qog kev tswj ntawm dc lub cev muaj zog, thiab nws tsis tas yuav ua kom yooj yim rau cov qauv lej ntawm ac lub cev rau kev txiav txim siab.
Matrix kev sib tshuam - kev sib tshuam tswj
VVVF zaus hloov dua siab tshiab, vector tswj zaus hloov dua siab tshiab thiab qhov ncaj qha torque tswj zaus hloov pauv yog txhua tus ac - dc - ac hloov dua siab tshiab. Nws qhov kev luv luv yog qhov tsis tshua muaj hluav taws xob lub zog, qhov loj dua qhov kev sib raug zoo tam sim no, lub dav hluav taws xob hauv dc xav tau lub zog loj ntim cov hluav taws xob, thiab lub zog txuas ntxiv tsis tuaj yeem xa rov qab rau hauv daim phiaj, uas yog, tsis tuaj yeem ua haujlwm plaub-plaub. Vim li no, matrix ac - ac hloov dua siab tshiab los ua hauv. Raws li kev hloov pauv ntawm matrix ac-ac hloov dua siab ceev txuag qhov nruab nrab dc txuas, yog li txuag cov ntim loj, kim electrolytic capacitor. Nws tuaj yeem ua tiav lub zog sib txuas ntawm l, sinusoidal cov tswv yim tam sim no thiab tuaj yeem khiav hauv plaub lub viav vias, lub zog ceev ntawm lub system muaj loj heev. Txawm hais tias thev naus laus zis tsis paub tab, nws tseem nyiam ntau tus kws tshawb fawb kawm nws tob. Nws lub ntsiab tsis yog qhov ncaj qha tswj tam sim no, sib nqus sib txuas sib npaug, tab sis lub zog ncaj qha yog cov khoom tswj tau kom ua tiav. Cov qauv tshwj xeeb yog:
1. Tswj cov kab hluav taws xob stator flux txuas los ntawm kev qhia txog stator flux tus neeg soj ntsuam kom paub ceev cov qib sensorless;
2. Tsis siv neeg daim ntawv cim (ID) tsis siv neeg paub cov cim ntawm lub cev muaj zog raws li kev ua lej ntawm lub cev muaj zog;
3. Suav qhov tseeb qhov muaj nuj nqis sib xws rau stator impedance, kev sib nrig sib nrig sib, muaj peev xwm sib nqus, tsis muaj zog, thiab lwm yam. Xam qhov tseeb qhov tseeb torque, stator flux txuas thiab rotor ceev rau lub sijhawm tswj;
4. Txheeb xyuas PWM teeb liab los ntawm kev sib xyaw band-tswj los ntawm kev sib nqus sib txuas thiab lub zog sib zog, thiab tswj lub xeev hloov ntawm lub inverter.
Xav tau tswj lub cev muaj zog thiab inverter nws tus kheej
1) tus naj npawb ntawm cov ncej ntawm lub cev muaj zog. Lub cev muaj zog dav dav tsis yog ntau dua (tsim nyog heev, txwv tsis pub lub zog inverter yuav tsim nyog).
2) cov yam ntxwv torque, lub cev tseem ceeb thiab lub zog loj. Xws li tib lub zog ntawm lub cev muaj zog, txheeb ze rau kev siab dhau qhov siab hom, qhov ntsuas qhov ntsuas tuaj yeem xaiv tau.
3) hluav taws xob sib xyaw. Txhawm rau kom txo qis kev cuam tshuam ntawm lub zog hluav taws xob loj, cov reactor tuaj yeem raug ntxiv rau hauv nruab nrab lossis xov xwm nkag ntawm lub zog hluav taws xob, lossis lub tshuab hluav taws xob ua ntej rho tawm tuaj yeem ntsia tau. Feem ntau, thaum qhov kev ncua deb ntawm lub cev muaj zog thiab qhov hloov pauv ntau dua 50m, lub reactor, lub lim lossis lub thaiv npog tiv thaiv cable yuav tsum txuas nrog hauv nruab nrab ntawm lawv.
Matrix ac-ac hloov dua siab tshiab muaj cov lus teb ceev ceev (<2ms), qhov tseeb ceev (± 2%, tsis muaj lub tswv yim PG), thiab qhov tseeb siab loj (<+ 3%). Nyob rau tib lub sijhawm, nws tseem muaj lub siab pib loj thiab siab torque siab, tshwj xeeb tshaj yog thaum tsis muaj kev ceev (suav nrog 0 ceev), nws tuaj yeem tawm 150% ~ 200% torque.
Xaiv cov hom ntawm inverter, raws li hom tshuab ntau lawm, kab kev nrawm nrawm, qhov nrawm nrawm nrawm, pib lub zog, txiav txim siab xaiv qhov tsim nyog tshaj plaws inverter tswj hom. Qhov hu ua qhov tsim nyog yog ob qho yooj yim siv, tab sis kuj muaj nyiaj txiag, txhawm rau kom ua tau raws li cov kev mob yooj yim thiab cov cai ntawm cov txheej txheem thiab cov khoom lag luam.
