Ib qho, yog vim li cas uas cuam tshuam rau lub tshuab hluav taws xob txhua hnub synchronous lub cev muaj zog hauv cov hlau nplaum sib txuas rau hauv chav tsev siv yog ib hom ntawm asynchronous synchronous lub cev, uas yog ua ke synchronously tom qab lub rotor AC pib thiab yog zoo li lub AC synchronous engine. Nws lub lag luam yog los ntawm lub stator kauj nyob rau hauv cov huab cua sib txawv tsim los ntawm tig magnetic teb thiab rotor magnet nruab nrab ntawm qhov kev sib nrauj attraction, thiaj li hais tias lub rotor thiab stator cua sib txawv magnetic teb synchronous tig thiab ua hauj lwm. Lub rotor yog sib npaug ntawm cov khoom seem ntawm lub cev, yog li ntawd lub zog qhov tseem ceeb yog siab. Vim tsis muaj kev cia siab tam sim no, nws tsis muaj qhov tsis muaj nqi me me. Lub zog ua haujlwm nce mus txog rau 96%, ntau tshaj 3-theem induction motor siab. Cov yam khoom cuam tshuam rau lub zog qhov chaw ntawm cov hlau nplaum hluav taws xob ntawm lub cev muaj zog yog qhov tsis zoo (voltage amplitude) thiab cov nqi dhia. Thaum lub qhov hluav taws xob ntawm qhov hluav taws xob yog siab tshaj qhov ntawm lub cav, lub tshuab hlau nplaum tas mus li yog ua haujlwm nrog cov cua ntsawj. Yog li ntawd, qhov kev hloov ntawm qhov hluav taws xob ntawm qhov hluav taws xob yuav ua rau lub cev muaj zog muaj zog thiab hloov qhov nyuaj. Yog qhov voltage amplitude thiab lub cev rov qab EMF taw tes kaw, qhov sib txawv ntawm qhov muaj li ntawm ± 2% voltage, qhov muaj zog lub zog qhov loj tshaj los yog sib npaug rau 0.9, txwv tsis pub, lub hwj chim tau qis dua; Ntxiv rau, thaum tus nqi PMSM qis dua 25%, qhov sib tw ntawm lub tshuab qis kuj tseem tsawg.
Qhov thib ob, txoj kev txhim kho lub zog ntawm cov tshuab hluav taws xob uas nyob ruaj khov yog soj ntsuam los ntawm qhov laj thawj uas tsis tshua muaj zog ntawm txhua tus taw tes zoo, qhov hauv qab no yog siv los kho raws li.
1. Raws li ntsuas cov nqi ntsuas uas tsim nyog hloov ntawm lub tshuab kom paub tseeb tias tus nqi tsim nyog.
2. Ua kom muaj zog, qhov tshwj xeeb tshaj yog cov davhlau ya nyob twg ntawm cov kab loj, qhov hluav taws xob feem ntau tsawg.
3. Qhov ruaj ruaj zoo ib qho ua rau nws ua kom ze rau qhov tsis-load rov qab EMF ntawm lub tshuab hluav taws xob tsis tu ncua.
4. Thaum qhov kev khiav hauj lwm muaj zog siab tshaj qhov EMF point ntawm Permanent magnet motor, nws yuav raug them nyiaj raws li qhov muaj zog ntawm lub zog inductive, thiaj li txhim kho qhov zoo tshaj.
5. Thaum qhov kev khiav hauj lwm muaj hluav taws xob tsawg dua li EMF cheej nyob ntawm lub cav hlau uas muaj peev xwm, nws tuaj yeem hloov kho qhov kev hloov qhov txua hluav taws xob, nce siab ntawm ob zaug, thiab ua kom lub zog khiav hauj lwm ze ntawm lub txee hluav taws xob taw tes los txhawb lub zog qhov zoo tshaj.
6. Rau cov hnyav hnyav ntev, hloov kho hluav taws xob txauv hloov, transformer ob voltage amplitude yog tseem qis dua li daim txiag hlau txuas mus ntxiv EMF taw tes, yuav hloov tau lub tshuab hluav taws xob daim npliag hluav taws xob, lub chaw txawb hluav taws xob.
Thib peb, kho qhov teeb meem no thiab cov teeb meem ntawm kev ua haujlwm los ntawm rau pawg ntawm cov roj ntau ntawm qhov kev xeem sib tw, kom lub hwjchim tsis yog nyob ntawm cov roj Oil Standard. Thaum xub thawj, lub substation thiab lub peev txheej tau raug kho kom zoo dua qhov dav hlau hluav taws xob. Qhov thib ob, raws li qhov kev ntsuam xyuas tau zoo ntawm ib qho zoo, cov kev sib cav sib ceg yog coj los siv, qee qhov kev pabcuam ntxiv, qee tus kho lub teeb tsa kev hloov chaw, thiab hloov lub zog ntawm lub cev. Qhov kev ntsuam xyuas pom tau hais tias tag nrho cov hluav taws xob muaj feem ntawm cov tshuab hluav taws xob sib txuas ua ke tas li yog ntxiv rau ib qho, tag nrho lwm cov neeg muaj feem tsim nyog, thiab lub hwj huam tau hloov cov hluav taws xob hluav taws xob zoo heev.
