01. MTPA thiab MTPV
Lub cev muaj zog sib nqus tas mus li yog lub hauv paus tseem ceeb ntawm cov chaw tsim hluav taws xob tsheb tshiab hauv Suav teb. Nws paub zoo tias thaum lub zog qis, lub cev muaj zog sib nqus tas mus li siv qhov siab tshaj plaws ntawm qhov tam sim no, uas txhais tau tias muab lub zog, qhov tsawg kawg nkaus ntawm cov hluav taws xob sib xyaw ua ke yog siv los ua kom tiav, yog li txo qhov poob tooj liab.
Yog li ntawm qhov ceev ceev, peb tsis tuaj yeem siv cov kab MTPA rau kev tswj hwm, peb yuav tsum siv MTPV, uas yog qhov siab tshaj plaws torque voltage ratio, rau kev tswj hwm. Uas yog hais tias, ntawm qee qhov ceev, ua rau lub cev muaj zog tso zis qhov siab tshaj plaws torque. Raws li lub tswv yim ntawm kev tswj hwm tiag tiag, muab lub torque, qhov ceev tshaj plaws tuaj yeem ua tiav los ntawm kev kho iq thiab id. Yog li qhov voltage cuam tshuam qhov twg? Vim tias qhov no yog qhov ceev tshaj plaws, lub voj voog txwv voltage yog kho. Tsuas yog los ntawm kev nrhiav qhov chaw siab tshaj plaws ntawm lub voj voog txwv no tuaj yeem pom qhov chaw siab tshaj plaws torque, uas txawv ntawm MTPA.
02. Cov xwm txheej tsav tsheb
Feem ntau, ntawm qhov tig ntawm qhov ceev (tseem hu ua qhov ceev pib), lub zog sib nqus pib tsis muaj zog, uas yog qhov taw tes A1 hauv daim duab hauv qab no. Yog li ntawd, ntawm qhov no, lub zog rov qab electromotive yuav loj heev. Yog tias lub zog sib nqus tsis tsis muaj zog thaum lub sijhawm no, xav tias lub laub raug yuam kom nce qhov ceev, nws yuav yuam kom iq tsis zoo, tsis tuaj yeem tso zis torque pem hauv ntej, thiab yuam kom nkag mus rau hauv lub xeev tsim hluav taws xob. Tau kawg, qhov taw tes no tsis tuaj yeem pom ntawm daim duab no, vim tias lub ellipse tab tom me me thiab tsis tuaj yeem nyob ntawm qhov taw tes A1. Peb tsuas tuaj yeem txo iq raws li lub ellipse, nce id, thiab mus ze rau qhov taw tes A2.
03. Cov xwm txheej ntawm kev tsim hluav taws xob
Vim li cas kev tsim hluav taws xob thiaj li xav tau lub zog hlau nplaum tsis muaj zog? Puas yog yuav tsum siv lub zog hlau nplaum muaj zog los tsim iq loj thaum tsim hluav taws xob ntawm qhov ceev ceev? Qhov no ua tsis tau vim tias ntawm qhov ceev ceev, yog tias tsis muaj lub zog hlau nplaum tsis muaj zog, lub zog rov qab electromotive, lub zog transformer electromotive, thiab lub zog impedance electromotive yuav loj heev, ntau tshaj qhov hluav taws xob muab hluav taws xob, ua rau muaj qhov tshwm sim phem heev. Qhov xwm txheej no yog SPO tsis tswj hwm kev kho hluav taws xob tsim hluav taws xob! Yog li ntawd, nyob rau hauv kev tsim hluav taws xob ceev ceev, lub zog hlau nplaum tsis muaj zog kuj yuav tsum tau ua, kom lub zog inverter tsim tau tswj tau.
Peb tuaj yeem tshuaj xyuas nws. Yog tias xav tias kev nres pib ntawm qhov chaw ua haujlwm ceev ceev B2, uas yog kev tawm tswv yim nres, thiab qhov ceev txo qis, tsis tas yuav muaj lub zog hlau nplaum tsis muaj zog. Thaum kawg, ntawm qhov chaw B1, iq thiab id tuaj yeem nyob ruaj khov. Txawm li cas los xij, thaum qhov ceev txo qis, qhov tsis zoo iq uas tsim los ntawm lub zog rov qab electromotive yuav tsawg dua thiab tsawg dua txaus. Ntawm lub sijhawm no, kev them nyiaj fais fab yog qhov xav tau los nkag mus rau kev siv zog nres.
04. Xaus Lus
Thaum pib kawm txog lub cev muaj zog hluav taws xob, nws yooj yim heev uas yuav muaj ob qho xwm txheej nyob ib puag ncig: tsav tsheb thiab tsim hluav taws xob. Qhov tseeb, peb yuav tsum xub kos cov voj voog MTPA thiab MTPV hauv peb lub hlwb, thiab lees paub tias iq thiab id thaum lub sijhawm no yog qhov tseeb, tau txais los ntawm kev xav txog lub zog rov qab electromotive.
Yog li, txog seb iq thiab id feem ntau yog tsim los ntawm lub zog fais fab lossis los ntawm lub zog rov qab electromotive, nws nyob ntawm lub inverter kom ua tiav kev tswj hwm. iq thiab id kuj muaj kev txwv, thiab kev tswj hwm tsis tuaj yeem tshaj ob lub voj voog. Yog tias lub voj voog txwv tam sim no dhau mus, IGBT yuav raug puas tsuaj; Yog tias lub voj voog txwv voltage dhau mus, lub zog fais fab yuav raug puas tsuaj.
Thaum lub sijhawm hloov kho, lub hom phiaj iq thiab id, nrog rau qhov tseeb iq thiab id, yog qhov tseem ceeb heev. Yog li ntawd, cov txheej txheem calibration siv hauv kev tsim kho kom calibrate qhov sib piv ntawm iq's id ntawm ntau qhov ceev thiab lub hom phiaj torques, txhawm rau kom ua tiav qhov zoo tshaj plaws. Nws tuaj yeem pom tias tom qab ncig ib puag ncig, qhov kev txiav txim siab zaum kawg tseem nyob ntawm kev tsim kho calibration.
