Magalimoto othamanga kwambiriakulandira chidwi chowonjezereka chifukwa cha ubwino wawo wodziwikiratu monga kuchulukitsidwa kwamphamvu, kukula kochepa ndi kulemera kwake, komanso kugwira ntchito bwino. Dongosolo loyendetsa bwino komanso lokhazikika ndiye chinsinsi chogwiritsa ntchito bwino kwambirima motors othamanga kwambiri. Nkhaniyi makamaka ikufotokoza zovuta zamota yothamanga kwambiriyendetsa ukadaulo kuchokera ku mbali za njira zowongolera, kuyerekezera kwamakona, ndi kapangidwe ka topology yamphamvu, ndikufotokozera mwachidule zotsatira za kafukufuku wapano kunyumba ndi kunja. Pambuyo pake, ikufotokoza mwachidule ndikuyembekeza chitukuko chamota yothamanga kwambiriteknoloji yoyendetsa.
Gawo 02 Zokhudza Kafukufuku
Magalimoto othamanga kwambiriali ndi zabwino zambiri monga kuchuluka kwamphamvu kwamphamvu, voliyumu yaying'ono ndi kulemera kwake, komanso magwiridwe antchito apamwamba. Amagwiritsidwa ntchito kwambiri m'magawo monga zamlengalenga, chitetezo cha dziko ndi chitetezo, kupanga ndi moyo watsiku ndi tsiku, ndipo ndizofunikira pakufufuza komanso malangizo achitukuko masiku ano. Pazinthu zothamanga kwambiri monga ma spindles amagetsi, ma turbomachinery, ma turbines amagetsi ang'onoang'ono, ndi kusungirako mphamvu za flywheel, kugwiritsa ntchito ma mota othamanga kwambiri kumatha kukwaniritsa dongosolo loyendetsa molunjika, kuthetsa zida zothamanga, kuchepetsa kwambiri voliyumu, kulemera, ndi kukonza ndalama. , pamene akuwongolera kwambiri kudalirika, ndipo ali ndi mwayi wogwiritsa ntchito kwambiri.Magalimoto othamanga kwambiriNthawi zambiri amatanthawuza kuthamanga kopitilira 10kr/mphindi kapena zovuta (chinthu cha liwiro ndi mizu yayikulu ya mphamvu) yopitilira 1 × Galimoto ya 105 ikuwonetsedwa mu Chithunzi 1, yomwe imafanizira zofananira za ma prototypes oyimira ma mota othamanga kwambiri m'nyumba zonse. ndi padziko lonse lapansi. Mzere wodutsa mu Chithunzi 1 ndi 1 × 105 mulingo wovuta, ndi zina
1,Zovuta mu High Speed Motor Drive Technology
1. Kukhazikika kwadongosolo pamaulendo apamwamba kwambiri
injini ikakhala yogwira ntchito pafupipafupi, chifukwa cha zofooka monga kutembenuka kwa analogi kupita ku digito, nthawi yamagetsi yamagetsi ya digito, ndi ma frequency osinthira ma inverter, ma frequency onyamula ma mota othamanga kwambiri amakhala otsika kwambiri. , zomwe zimapangitsa kuchepa kwakukulu kwa kayendetsedwe ka galimoto.
2. Vuto la kuyerekezera malo ozungulira molunjika kwambiri pama frequency ofunikira
Pantchito yothamanga kwambiri, kulondola kwa malo a rotor ndikofunikira kuti injini igwire ntchito. Chifukwa chodalirika chochepa, kukula kwakukulu, ndi kukwera mtengo kwa masensa amtundu wamakina, ma aligorivimu opanda sensor nthawi zambiri amagwiritsidwa ntchito pamakina oyendetsa magalimoto othamanga kwambiri. Komabe, pansi pazikhalidwe zoyambira pafupipafupi, kugwiritsa ntchito ma aligorivimu opanda sensors kumakhala kosavuta kuzinthu zomwe sizili bwino monga inverter nonlinearity, ma harmonics apakati, zosefera za loop, ndi kupatuka kwa magawo a inductance, zomwe zimapangitsa kuti pakhale zolakwika zazikulu pakuyerekeza kwa malo ozungulira.
3. Kuponderezedwa kwa Ripple mumayendedwe othamanga kwambiri
Kuchepetsa pang'ono kwa ma mota othamanga kwambiri kumabweretsa vuto la ma ripple apano. Kutayika kowonjezera kwa mkuwa, kutayika kwachitsulo, kugwedezeka kwa torque, ndi phokoso lakunjenjemera lomwe limabwera chifukwa cha kuchuluka kwaposachedwa kumatha kukulitsa kutayika kwa makina othamanga kwambiri, kumachepetsa magwiridwe antchito, komanso kusokoneza kwamagetsi komwe kumachitika chifukwa cha phokoso lamphamvu kwambiri kumatha kufulumizitsa ukalamba wa dalaivala. Zomwe zili pamwambazi zimakhudza kwambiri magwiridwe antchito amagalimoto othamanga kwambiri, ndipo kukhathamiritsa kwa ma frequency otsika otsika ndikofunikira pamagalimoto othamanga kwambiri. Mwachidule, mapangidwe a makina oyendetsa magalimoto othamanga kwambiri amafunikira kuganizira mozama zinthu zingapo, kuphatikiza kulumikizana kwa loop, kuchedwa kwa dongosolo, zolakwika za parameter, ndi zovuta zaukadaulo monga kuponderezana kwaposachedwa. Ndi njira yovuta kwambiri yomwe imapangitsa kuti pakhale zofunikira kwambiri panjira zowongolera, kulondola kwa malo ozungulira, komanso kapangidwe kamphamvu ka topology.
2, Njira Yowongolera ya High Speed Motor Drive System
1. Kujambula kwa High Speed Motor Control System
Makhalidwe a kuchuluka kwa ma frequency oyambira komanso ma frequency otsika onyamula pamakina othamanga kwambiri, komanso mphamvu ya kulumikizana kwa ma mota ndikuchedwa pa dongosolo, sizinganyalanyazidwe. Chifukwa chake, poganizira zinthu ziwiri zazikuluzikulu zomwe tafotokozazi, kufananiza ndikuwunikanso kumangidwanso kwa makina othamanga kwambiri ndiye chinsinsi chopititsira patsogolo kuyendetsa bwino kwa ma mota othamanga kwambiri.
2. Decoupling Control Technology ya High Speed Motors
Ukadaulo womwe umagwiritsidwa ntchito kwambiri pamakina oyendetsa magalimoto apamwamba kwambiri ndi FOC control. Poyankha vuto lalikulu lolumikizana lomwe limabwera chifukwa cha kuchuluka kwa magwiridwe antchito, njira yayikulu yofufuzira pano ndikuwongolera njira zowongolera. Njira zowongolera zolumikizira zomwe zaphunziridwa pakali pano zitha kugawidwa m'njira zowongolera zolumikizirana, zolipira zosokoneza potengera njira zowongolera zolumikizirana, ndi njira zowongolera zowongolera ma vector. Model zochokera njira kulamulira decoupling makamaka monga feedforward decoupling ndi ndemanga decoupling, koma njira imeneyi ndi tcheru kwa magawo galimoto ndipo zingachititse kusakhazikika dongosolo pa milandu lalikulu chizindikiro zolakwa, ndipo sangathe kukwaniritsa decoupling wathunthu. Kusayenda bwino kophatikizana kumalepheretsa kusiyanasiyana kwake. Njira ziwiri zomalizira zochepetsera mgwirizano pano ndizo malo ofufuza.
3. Kuchedwa Kulipilira Technology kwa High Speed Motor Systems
Ukadaulo wowongolera ma decoupling amatha kuthana bwino ndi vuto lophatikizana lamayendedwe othamanga kwambiri, koma ulalo wochedwetsa womwe umayambitsidwa ndi kuchedwa ukadalipo, kotero kubweza kogwira mtima kwadongosolo kumafunika. Pakalipano, pali njira ziwiri zazikulu zolipirira njira zochepetsera dongosolo: njira zolipirira zotengera zitsanzo ndi njira zolipirira zodziyimira pawokha.
Gawo 03 Mapeto a Kafukufuku
Kutengera ndi zomwe kafukufuku wapeza mumota yothamanga kwambiriukadaulo woyendetsa m'magulu amaphunziro, kuphatikiza ndi zovuta zomwe zilipo, kakulidwe ndi kafufuzidwe kamagalimoto othamanga kwambiri makamaka zimaphatikizapo: 1) kafukufuku wolosera molondola zazomwe zikuchitika komanso kuchedwa kwa chipukuta misozi; 3) Kafukufuku wama algorithms apamwamba kwambiri owongolera magwiridwe antchito amagalimoto othamanga kwambiri; 4) Kafukufuku wa kuyerekezera kolondola kwapangodya ndi mtundu wanthawi zonse woyezera malo a rotor pamakina othamanga kwambiri; 5) Kafukufuku paukadaulo wamalipiro athunthu pazolakwa zamachitidwe oyerekeza malo othamanga kwambiri; 6) Kafukufuku pa Kuthamanga Kwambiri ndi Kutayika Kwambiri kwa High Speed Motor Power Topology.
