Ama-motor anesivinini esikhuluzithola ukunakwa okwandayo ngenxa yezinzuzo zazo ezisobala njengokuminyana kwamandla aphezulu, usayizi omncane nesisindo, kanye nokusebenza kahle kakhulu. Uhlelo lokushayela olusebenza kahle noluzinzile luyisihluthulelo sokusebenzisa ngokugcwele ukusebenza okuhle kakhuluama-motor anesivinini esikhuluLesi sihloko sihlaziya kakhulu ubunzima beinjini yesivinini esikhuluukuqondisa ubuchwepheshe ezicini zesu lokulawula, ukulinganisa kwekhoneni, kanye nomklamo we-topology yamandla, futhi kufingqa imiphumela yocwaningo lwamanje ekhaya nakwamanye amazwe. Ngemuva kwalokho, kufingqa futhi kubheke phambili ekuthuthukisweni kwe-injini yesivinini esikhuluubuchwepheshe bokushayela.
Ingxenye 02 Okuqukethwe Kocwaningo
Ama-motor anesivinini esikhuluzinezinzuzo eziningi ezifana nobuningi bamandla aphezulu, ivolumu encane nesisindo, kanye nokusebenza kahle okuphezulu. Zisetshenziswa kabanzi emikhakheni efana nezindiza, ukuvikela nokuphepha kwezwe, ukukhiqiza kanye nokuphila kwansuku zonke, futhi ziyisiqondiso socwaningo oludingekayo kanye nentuthuko namuhla. Ezisetshenzisweni zomthwalo wejubane eliphezulu njenge-spindle kagesi, i-turbomachinery, ama-turbine amancane egesi, kanye nesitoreji samandla se-flywheel, ukusetshenziswa kwama-motor anejubane eliphezulu kungafinyelela isakhiwo sokushayela ngqo, kususe amadivayisi ejubane eliguquguqukayo, kunciphise kakhulu ivolumu, isisindo, kanye nezindleko zokulungisa, kuyilapho kuthuthukiswa kakhulu ukuthembeka, futhi kunamathuba amaningi okusebenzisa.Ama-motor anesivinini esikhulungokuvamile kubhekisela ezivivinyweni ezidlula u-10kr/min noma amanani obunzima (umkhiqizo wejubane kanye nempande yesikwele yamandla) edlula u-1 × Injini engu-105 iboniswe kuMfanekiso 1, oqhathanisa idatha efanele yezinye izinhlobo ezimele zama-motor anejubane eliphezulu kokubili ngaphakathi nangaphandle. Umugqa onamachashazi kuMfanekiso 1 uyizinga lobunzima elingu-1 × 105, njll.
1,Ubunzima kubuchwepheshe bokushayela ngesivinini esikhulu
1. Izinkinga zokuzinza kwesistimu kumaza ayisisekelo aphezulu
Uma injini isesimweni sokusebenza okuphezulu kwemvamisa eyisisekelo, ngenxa yemikhawulo efana nesikhathi sokuguqulwa kwe-analog-to-digital, isikhathi sokusebenza kwe-algorithm yesilawuli sedijithali, kanye nemvamisa yokushintsha i-inverter, imvamisa yokuthwala yesistimu yokushayela imoto yesivinini esikhulu iphansi kakhulu, okuholela ekwehleni okukhulu kokusebenza kwenjini.
2. Inkinga yokuqagela isikhundla se-rotor ngokunemba okuphezulu ku-frequency eyisisekelo
Ngesikhathi sokusebenza ngesivinini esikhulu, ukunemba kwesikhundla se-rotor kubalulekile ekusebenzeni kahle kwemoto. Ngenxa yokuthembeka okuphansi, usayizi omkhulu, kanye nezindleko eziphezulu zezinzwa zesikhundla semishini, ama-algorithm angenazo izinzwa avame ukusetshenziswa ezinhlelweni zokulawula izimoto zesivinini esikhulu. Kodwa-ke, ngaphansi kwezimo zemvamisa yokusebenza ephezulu, ukusetshenziswa kwama-algorithm angenazo izinzwa zesikhundla kuthinteka yizici ezingezona ezifanelekile njenge-inverter nonlinearity, ama-harmonics endawo, izihlungi ze-loop, kanye nokuphambuka kwamapharamitha e-inductance, okuholela emaphutheni amakhulu okulinganisa isikhundla se-rotor.
3. Ukucindezela ama-ripple ezinhlelweni zokushayela izimoto ezinesivinini esikhulu
Ukungena okuncane kwama-motor anejubane eliphezulu kuholela enkingeni ye-ripple enkulu yamandla kagesi. Ukulahleka okwengeziwe kwethusi, ukulahlekelwa yinsimbi, i-torque ripple, nomsindo wokudlidliza obangelwa i-ripple yamandla kagesi ephezulu kungakhuphula kakhulu ukulahleka kwezinhlelo zama-motor anejubane eliphezulu, kunciphise ukusebenza kwe-motor, kanye nokuphazamiseka kwe-electromagnetic okubangelwa umsindo wokudlidliza okuphezulu kungasheshisa ukuguga komshayeli. Izinkinga ezingenhla zithinta kakhulu ukusebenza kwezinhlelo zama-motor drive anejubane eliphezulu, futhi ukwakheka kahle kwamasekethe ehadiwe okulahlekelwa okuphansi kubalulekile ezinhlelweni zama-motor drive anejubane eliphezulu. Ngamafuphi, ukwakheka kohlelo lwe-motor drive olunejubane eliphezulu kudinga ukucatshangelwa okubanzi kwezinto eziningi, kufaka phakathi ukuhlanganiswa kwe-current loop, ukubambezeleka kohlelo, amaphutha epharamitha, kanye nobunzima bobuchwepheshe njengokucindezela kwe-current ripple. Kuyinqubo eyinkimbinkimbi kakhulu ebeka izidingo eziphezulu kumasu okulawula, ukunemba kokulinganisa isikhundla se-rotor, kanye nomklamo we-topology yamandla.
2, Isu Lokulawula Lohlelo Lokushayela Imoto Esheshayo
1. Ukumodela kweSistimu Yokulawula Imoto Esheshayo
Izici zemvamisa yokusebenza ephezulu kanye nesilinganiso semvamisa ephansi yokusebenza ezinhlelweni zokushayela izimoto ezinejubane eliphezulu, kanye nomthelela wokuhlanganiswa kwezimoto kanye nokubambezeleka ohlelweni, azinakwa. Ngakho-ke, uma ucabangela lezi zici ezimbili ezinkulu ezingenhla, ukwenza imodeli nokuhlaziya ukwakhiwa kabusha kwezinhlelo zokushayela izimoto ezinejubane eliphezulu kuyisihluthulelo sokuthuthukisa ukusebenza kokushayela kwama-motor anejubane eliphezulu.
2. Ubuchwepheshe Bokulawula Ukuhlukanisa Ama-High Speed Motors
Ubuchwepheshe obusetshenziswa kakhulu ezinhlelweni zokushayela izimoto ezisebenza kahle kakhulu ukulawula i-FOC. Ukuphendula inkinga enkulu yokuxhumanisa ebangelwa imvamisa ephezulu yokusebenza, isiqondiso esiyinhloko socwaningo njengamanje amasu okulawula ukuhlukanisa. Amasu okulawula ukuhlukanisa afundwayo njengamanje angahlukaniswa kakhulu ngamasu okulawula ukuhlukanisa asekelwe kumodeli, amasu okulawula ukuhlukanisa asekelwe ekuphazamisekeni, kanye namasu okulawula ukuhlukanisa asekelwe kumlawuli we-vector oyinkimbinkimbi. Amasu okulawula ukuhlukanisa asekelwe kumodeli afaka phakathi ukuhlukanisa okuphakelayo kanye nokuhlukanisa impendulo, kodwa leli su liyazwela kumapharamitha emoto futhi lingaholela nasekungazinzini kwesistimu ezimweni zamaphutha amakhulu epharamitha, futhi alikwazi ukufeza ukuhlukanisa okuphelele. Ukusebenza okungekuhle kokuhlukanisa okuguquguqukayo kunciphisa ububanzi bokusetshenziswa kwalo. Amasu okulawula ukuhlukanisa amabili okugcina njengamanje ayizindawo ezishisayo zocwaningo.
3. Ubuchwepheshe Bokunxephezela Ukubambezeleka Kwezinhlelo Zezimoto Ezisheshayo
Ubuchwepheshe bokulawula ukuhlukanisa bungayixazulula ngempumelelo inkinga yokuxhumanisa yezinhlelo zokushayela izimoto ezinesivinini esikhulu, kodwa isixhumanisi sokulibaziseka esethulwe ngokubambezeleka sisakhona, ngakho-ke isinxephezelo esisebenzayo esisebenzayo sokubambezeleka kwesistimu siyadingeka. Njengamanje, kunezindlela ezimbili eziyinhloko zesinxephezelo esisebenzayo sokubambezeleka kwesistimu: amasu esinxephezelo asekelwe kumodeli kanye namasu esinxephezelo esizimele semodeli.
Ingxenye 03 Isiphetho Socwaningo
Ngokusekelwe ezifinyelelwe ocwaningweni lwamanje kuinjini yesivinini esikhuluubuchwepheshe bokushayela emphakathini wezemfundo, kuhlanganiswe nezinkinga ezikhona, izinkomba zokuthuthukiswa nokucwaninga kwama-motor anejubane eliphezulu zifaka phakathi: 1) ucwaningo ngokubikezela okunembile kwezinkinga eziphathelene nokubambezeleka kwe-frequency ephezulu kanye ne-active compensation; 3) Ucwaningo ngama-algorithms okulawula ukusebenza okuphezulu kwama-motor anejubane eliphezulu; 4) Ucwaningo ngokuqagela okunembile kwendawo yekona kanye nemodeli yokulinganisa isikhundla se-rotor ye-domain egcwele ijubane lama-motor anejubane eliphezulu; 5) Ucwaningo ngobuchwepheshe bokunxephezela okugcwele ngamaphutha kumamodeli okulinganisa isikhundla se-motor anejubane eliphezulu; 6) Ucwaningo ngokuqagela okuphezulu kanye nokulahlekelwa okuphezulu kwe-High Speed Motor Power Topology.
