Umuvuduko mwinshi wa moteri ya tekinoroji hamwe niterambere ryayo

Moteri yihutabarimo kwitabwaho cyane kubera inyungu zabo zigaragara nkubucucike bukabije, ubunini nuburemere, hamwe nakazi keza. Sisitemu ikora neza kandi ihamye ni urufunguzo rwo gukoresha byimazeyo imikorere myiza yamoteri yihuta. Iyi ngingo isesengura cyane cyane ingorane zamoteri yihutagutwara tekinoroji uhereye muburyo bwo kugenzura ingamba, kugereranya inguni, no gushushanya imbaraga za topologiya, kandi ukavuga muri make ibyavuye mubushakashatsi murugo no hanze. Nyuma, irerekana muri make kandi ikanateganya iterambere ryiteramberemoteri yihutagutwara ikoranabuhanga.

Igice cya 02 Ibirimo Ubushakashatsi

Moteri yihutaufite ibyiza byinshi nkubucucike bukabije, ingano ntoya nuburemere, hamwe nakazi keza. Zikoreshwa cyane mubice nko mu kirere, kurinda umutekano n’umutekano w’igihugu, umusaruro n’ubuzima bwa buri munsi, kandi ni nkenerwa mubushakashatsi hamwe nicyerekezo cyiterambere muri iki gihe. Mubisabwa byihuta byumuvuduko nka spindles yamashanyarazi, turbomachinery, gaz gaz turbine, hamwe nububiko bwingufu za flawheel, ikoreshwa rya moteri yihuta irashobora kugera kumiterere itaziguye, gukuraho ibikoresho byihuta, kugabanya cyane, uburemere, hamwe nigiciro cyo kubungabunga , mugihe bitezimbere cyane kwizerwa, kandi bifite ibyifuzo byinshi byo gusaba.Moteri yihutamubisanzwe bivuga umuvuduko urenze 10kr / min cyangwa indangagaciro zingorabahizi (ibicuruzwa byumuvuduko numuzi wa kare kare yimbaraga) zirenga 1 × Moteri ya 105 irerekanwa mumashusho 1, igereranya amakuru ajyanye na prototypes zimwe na zimwe zihagarariye moteri yihuta haba mu gihugu imbere no ku rwego mpuzamahanga. Umurongo ucagaguye mu gishushanyo 1 ni 1 × 105 urwego rugoye, nibindi

1 、Ingorane muburyo bwihuse bwo gutwara ibinyabiziga

1. Ibibazo bya sisitemu ihamye kumurongo munini wibanze

Iyo moteri iri murwego rwohejuru rukora ibintu byingenzi, kubera imbogamizi nkigihe cyo kugereranya-na-digitale, igihe cyo kugenzura algorithm ya digitale, nigihe cyo guhinduranya inverter, inshuro zitwara sisitemu yihuta ya sisitemu yo gutwara ibinyabiziga yihuta cyane , bivamo kugabanuka gukabije kwimikorere ya moteri.

2. Ikibazo cya rotorisiyo yo hejuru igereranya umwanya munini

Mugihe cyihuta cyane, imikorere ya rotor ni ngombwa kugirango imikorere ya moteri ikorwe. Bitewe no kwizerwa guke, ubunini bunini, nigiciro kinini cyibikoresho bya sensorisiyo yumwanya, algorithm ya sensorless ikoreshwa kenshi muri sisitemu yo kugenzura moteri yihuta. Nubwo bimeze bityo ariko, murwego rwo hejuru rwibikorwa byingenzi, ikoreshwa ryimyanya idafite algorithms irashobora kwibasirwa nibintu bitari byiza nka inverter idafite umurongo, guhuza umwanya, guhuza akayunguruzo, no gutandukanya ibipimo bya inductance, bikavamo amakosa akomeye yo kugereranya umwanya wa rotor.

3. Guhagarika ibicuruzwa muri sisitemu yo gutwara ibinyabiziga byihuse

Induction ntoya ya moteri yihuta byanze bikunze biganisha kukibazo cya ripple nini. Gutakaza umuringa wongeyeho, gutakaza ibyuma, guhindagurika kwa torque, hamwe n urusaku rwinyeganyeza rwatewe numuvuduko ukabije urashobora kongera cyane igihombo cya sisitemu yihuta ya moteri, kugabanya imikorere ya moteri, no kwivanga kwa electromagnetiki biterwa n urusaku rwinshi rwo kwinyeganyeza bishobora kwihutisha gusaza kwabasaza umushoferi. Ibibazo byavuzwe haruguru bigira ingaruka cyane kumikorere ya sisitemu yo gutwara ibinyabiziga byihuta cyane, kandi igishushanyo mbonera cyibikoresho bito bito byingirakamaro ni ngombwa kuri sisitemu yo gutwara ibinyabiziga yihuta. Muri make, igishushanyo mbonera cya sisitemu yihuta ya moteri isaba gutekereza cyane kubintu byinshi, harimo guhuza ibizunguruka, gutinda kwa sisitemu, amakosa yibintu, hamwe nibibazo bya tekiniki nko guhagarika imvururu. Ninzira igoye cyane ishyira ibyifuzo byinshi kubikorwa byo kugenzura, kugereranya umwanya wa rotor, no gushushanya imbaraga za topologiya.

2 Strategy Ingamba zo Kugenzura Sisitemu Yihuta Yimodoka

1. Kwerekana uburyo bwihuse bwo kugenzura ibinyabiziga

Ibiranga ibikorwa byibanze bikora cyane hamwe nigipimo gito cyabatwara muri sisitemu yihuta yihuta ya moteri, kimwe ningaruka zo guhuza moteri no gutinda kuri sisitemu, ntishobora kwirengagizwa. Kubwibyo, urebye ibintu bibiri byingenzi byavuzwe haruguru, kwerekana no gusesengura iyubakwa rya sisitemu yihuta yo gutwara ibinyabiziga nurufunguzo rwo kurushaho kunoza imikorere yimodoka yihuta.

2. Gukuramo tekinoroji yo kugenzura kuri moteri yihuta

Ikoranabuhanga rikoreshwa cyane muri sisitemu yo gukora moteri ikora cyane ni kugenzura FOC. Mu gusubiza ikibazo gikomeye cyo guhuza cyatewe ninshuro nini yo gukora inshuro nyinshi, icyerekezo nyamukuru cyubushakashatsi muri iki gihe ni ugukuraho ingamba zo kugenzura. Ingamba zo kugenzura decoupling ingamba zirimo kwigwa zirashobora kugabanywa cyane cyane muburyo bwo kugenzura uburyo bwo kugenzura ibicuruzwa, indishyi z’imivurungano zishingiye ku ngamba zo kugenzura, hamwe n’ingamba zikomeye zo kugenzura zishingiye ku kugenzura. Icyitegererezo gishingiye ku kugenzura ingamba zirimo cyane cyane kugaburira no kugarura ibitekerezo, ariko iyi ngamba irumva ibipimo bya moteri kandi irashobora no gutuma habaho ihungabana rya sisitemu mugihe habaye amakosa manini manini, kandi ntishobora kugera kumurongo wuzuye. Imikorere idahwitse yimikorere igabanya imipaka ikoreshwa. Uburyo bubiri bwa nyuma bwo kugenzura ingamba ni ubushakashatsi bwihuse.

3. Gutinda Ikoranabuhanga ryindishyi kuri sisitemu yihuta ya moteri

Gukuraho tekinoroji yo kugenzura birashobora gukemura neza ikibazo cyo guhuza sisitemu yihuta yo gutwara ibinyabiziga, ariko guhuza gutinda kwatangijwe nubukererwe biracyahari, bityo hakenewe indishyi zifatika zo gutinda kwa sisitemu. Kugeza ubu, hari ingamba ebyiri zingenzi zindishyi zo gutinda kwa sisitemu: ingamba zishingiye ku ndishyi zishingiye ku ngero n’ingamba zigenga zigenga.

Igice cya 03 Umwanzuro wubushakashatsi

Ukurikije ibyagezweho mubushakashatsi murimoteri yihutagutwara ikoranabuhanga mumuryango w’amasomo, uhujwe n’ibibazo bihari, iterambere n’icyerekezo cy’ubushakashatsi bwa moteri yihuta cyane cyane harimo: 1) ubushakashatsi ku guhanura neza neza ibijyanye n’umuvuduko mwinshi w’ibanze hamwe n’indishyi zikomeye zitinda ku bibazo bifitanye isano; 3) Ubushakashatsi kuri dinamike ikora cyane igenzura algorithm ya moteri yihuta; 4) Ubushakashatsi ku igereranya ryukuri ryimyanya yimfuruka hamwe numuvuduko wuzuye wa rotor umwanya wo kugereranya moderi ya ultra yihuta ya moteri; 5) Ubushakashatsi kuri tekinoroji yuzuye yindishyi zamakosa muburyo bwo kugereranya ibinyabiziga byihuta; 6) Ubushakashatsi kuri Frequency Yinshi no Gutakaza Byinshi Byihuta Byimodoka Topologiya.
