Izinjini zejubane eliphezulubathola ukunakwa okukhulayo ngenxa yezinzuzo zabo ezisobala njengokuminyana kwamandla aphezulu, usayizi omncane nesisindo, kanye nokusebenza kahle okuphezulu.Uhlelo lokushayela olusebenzayo noluzinzile luyisihluthulelo sokusebenzisa ngokugcwele ukusebenza okuhle kakhulu kweamamotho anesivinini esikhulu.Lesi sihloko sihlaziya kakhulu ubunzima beinjini enesivinini esikhulushayela ubuchwepheshe kusukela ezicini zesu lokulawula, ukulinganisa kwekhona, kanye nomklamo we-topology yamandla, futhi ifingqa imiphumela yamanje yocwaningo ekhaya naphesheya.Ngemva kwalokho, ifinyeza futhi ilindele umkhuba wokuthuthuka weinjini enesivinini esikhuluukushayela ubuchwepheshe.
Ingxenye 02 Okuqukethwe Kocwaningo
Izinjini zejubane eliphezuluzinezinzuzo eziningi ezifana nokuminyana kwamandla aphezulu, umthamo omncane nesisindo, nokusebenza kahle okuphezulu.Asetshenziswa kakhulu emikhakheni efana ne-aerospace, ukuvikela izwe nokuphepha, ukukhiqiza kanye nempilo yansuku zonke, futhi adingekayo okuqukethwe kocwaningo kanye neziqondiso zentuthuko namuhla.Kuzinhlelo zokusebenza ezilayisha isivinini esikhulu njengama-spindle kagesi, ama-turbomachinery, ama-turbines egesi amancane, kanye nesitoreji samandla e-flywheel, ukusetshenziswa kwama-motor anesivinini esiphezulu kungafinyelela ukwakheka kokushayela okuqondile, kususe amadivaysi esivinini aguquguqukayo, kunciphise kakhulu ivolumu, isisindo, kanye nezindleko zokunakekela. , kuyilapho ithuthukisa kakhulu ukwethembeka, futhi inamathemba okusebenza abanzi kakhulu.Izinjini zejubane eliphezulungokuvamile ibhekisela esivinini esingaphezu kuka-10kr/min noma amanani obunzima (umkhiqizo wesivinini kanye nezimpande eziyisikwele zamandla) ezedlula u-1 × Injini engu-105 iboniswa kuMfanekiso 1, oqhathanisa idatha efanele yezinye izinhlobo ezimele amamotho anesivinini esikhulu kokubili ekhaya. nakwamanye amazwe.Umugqa wedeshi kuMfanekiso 1 yizinga lobunzima elingu-1 × 105, njll
1,Ubunzima ku-High Speed Motor Drive Technology
1. Izinkinga zokuzinza kwesistimu kumafrikhwensi aphezulu ayisisekelo
Lapho injini isesimweni sokusebenza okuphezulu okuyisisekelo sokuvama, ngenxa yemikhawulo efana nesikhathi sokuguqulwa kwe-analog-to-digital, isikhathi sokwenza i-algorithm yesilawuli sedijithali, kanye nemvamisa yokushintsha i-inverter, imvamisa yenkampani yenethiwekhi ye-high-speed motor drive system iphansi kakhulu. , okuholela ekwehleni okukhulu ekusebenzeni kwezimoto.
2. Inkinga yokulinganisa okuphezulu kokunemba kwe-rotor kumafrikhwensi ayisisekelo
Ngesikhathi sokusebenza ngesivinini esikhulu, ukunemba kwesikhundla se-rotor kubalulekile ekusebenzeni kokusebenza kwenjini.Ngenxa yokuthembeka okuphansi, usayizi omkhulu, kanye nezindleko eziphakeme zezinzwa zokuma kwemishini, ama-algorithms angenazinzwa avame ukusetshenziswa ezinhlelweni zokulawula izimoto ezihamba ngesivinini esikhulu.Kodwa-ke, ngaphansi kwezimo zemvamisa yokusebenza okuphezulu okuyisisekelo, ukusetshenziswa kwama-algorithms angenazinzwa zokuma kungase kube sengozini yezinto ezingezona ekahle ezifana ne-inverter nonlinearity, i-harmonics yendawo, izihlungi ze-loop, nokuchezuka kwepharamitha ye-inductance, okuholela kumaphutha abalulekile okulinganisa indawo ye-rotor.
3. Ukucindezelwa kwe-Ripple kumasistimu we-motor drive enesivinini esikhulu
I-inductance encane yamamotho anesivinini esikhulu ngokungangabazeki iholela enkingeni ye-ripple yamanje enkulu.Ukulahleka okwengeziwe kwethusi, ukulahleka kwensimbi, i-torque ripple, nomsindo wokudlidliza obangelwa ukunyakaza okuphezulu kwamanje kungakhuphula kakhulu ukulahleka kwezinhlelo zezimoto ezinesivinini esikhulu, kunciphise ukusebenza kwezimoto, kanye nokuphazamiseka kazibuthe okubangelwa umsindo wokudlidliza okuphezulu kungasheshisa ukuguga umshayeli.Lezi zinkinga ezingenhla zithinta kakhulu ukusebenza kwamasistimu okushayela kwezimoto ezinesivinini esikhulu, futhi idizayini yokwenza kahle yamasekhethi ezingxenyekazi zekhompuyutha ezilahlekelwa kancane ibalulekile ezinhlelweni zokushayela kwezimoto ezinesivinini esikhulu.Kafushane, idizayini yesistimu yokushayela imoto enesivinini esikhulu idinga ukucatshangelwa okuphelele kwezinto eziningi, okuhlanganisa ukuhlanganisa iluphu yamanje, ukubambezeleka kwesistimu, amaphutha epharamitha, nobunzima bobuchwepheshe obufana nokucindezelwa kwe-ripple kwamanje.Kuyinqubo eyinkimbinkimbi kakhulu ebeka izidingo eziphezulu kumasu okulawula, ukunemba kokulinganisa indawo ye-rotor, kanye nomklamo we-topology yamandla.
2, Isu Lokulawula Lohlelo LweDrayivu Yezimoto Ezisheshayo
1. Ukumodela kwe-High Speed Motor Control System
Izici zokusebenzisa imvamisa eyisisekelo yokusebenza okuphezulu kanye nenani eliphansi le-frequency yenkampani yenethiwekhi ezinhlelweni zokushayela kwezimoto ezinesivinini esikhulu, kanye nomthelela wokuhlangana kwezimoto nokubambezeleka ohlelweni, azikwazi ukushaywa indiva.Ngakho-ke, ukucabangela lezi zici ezimbili ezinkulu ezingenhla, ukumodela nokuhlaziya ukwakhiwa kabusha kwezinhlelo ze-motor drive enesivinini esikhulu kuyisihluthulelo sokuqhubeka nokuthuthukisa ukusebenza kokushayela kwamamotho anesivinini esikhulu.
2. I-Decoupling Control Technology ye-High Speed Motors
Ubuchwepheshe obusetshenziswa kakhulu ezinhlelweni zokushayela ezisebenza kahle kakhulu ukulawulwa kwe-FOC.Ukuphendula inkinga enkulu yokuhlanganisa ebangelwa imvamisa ephezulu yokusebenza okuyisisekelo, isiqondiso esiyinhloko socwaningo okwamanje amasu okulawula okunqamula.Amasu okulawula ukunqamula afundwayo njengamanje angahlukaniswa kakhulu abe amasu okulawula ukuhlukanisa asekelwe kumodeli, amasu okulawula ukuhlukanisa asekelwe esinxephezelweni sokuphazamiseka, kanye namasu okulawula okuhlukanisa ama-vector asekelwe ku-vector.Amasu okulawula okuhlukaniswa okusekelwe kumodeli ngokuyinhloko ahlanganisa ukunqanyulwa kwe-feedforward nokunqamula impendulo, kodwa leli su liyazwela kumapharamitha wezimoto futhi lingaholela ngisho nasekungazinzini kwesistimu ezimeni zamaphutha amakhulu epharamitha, futhi alikwazi ukuzuza ukuhlukaniswa okuphelele.Ukusebenza kabi kwe-dynamic decoupling kunciphisa umkhawulo wohlelo lwayo lokusebenza.Amasu amabili okugcina okulawula okunqamula ama-coupling okwamanje ayizindawo ezithandwa kakhulu zocwaningo.
3. Ukubambezela Ubuchwepheshe Besinxephezelo se-High Speed Motor Systems
Ubuchwepheshe bokulawula ukunqamula bungaxazulula ngempumelelo inkinga yokuhlanganisa amasistimu okushayela kwezimoto ezinesivinini esikhulu, kodwa isixhumanisi sokulibaziseka esethulwe ukubambezeleka sisekhona, ngakho-ke isinxephezelo esisebenzayo esisebenzayo sokubambezeleka kwesistimu siyadingeka.Njengamanje, kunezindlela ezimbili eziyinhloko zesinxephezelo esisebenzayo sokubambezeleka kwesistimu: amasu esinxephezelo asekelwe kumamodeli kanye namasu esinxephezelo azimele angamamodeli.
Ingxenye 03 Isiphetho Socwaningo
Ngokusekelwe kuzimpumelelo zocwaningo lwamanje kuinjini enesivinini esikhuluukushayela ubuchwepheshe emphakathini wezemfundo, kuhlanganiswe nezinkinga ezikhona, ukuthuthukiswa kanye nezikhombisi-ndlela zocwaningo zamamotho anesivinini esikhulu ngokuyinhloko zihlanganisa: 1) ucwaningo lokubikezela okunembayo kwezindaba eziphathelene nokubambezeleka kwesinxephezelo esiphezulu samanje nesisebenzayo;3) Ucwaningo lwama-algorithms okulawula ukusebenza okunamandla aphezulu kumamotho anesivinini esikhulu;4) Ucwaningo ngokulinganisa okunembile kwendawo yekhona kanye nemodeli yokulinganisa yesizinda se-rotor yesivinini esigcwele samamotho anesivinini esikhulu;5) Ucwaningo ngobuchwepheshe besinxephezelo esigcwele ngamaphutha kumamodeli wesilinganiso sendawo yemoto enesivinini esikhulu;6) Ucwaningo mayelana ne-High Frequency kanye nokulahlekelwa okuphezulu kwe-High Speed Motor Power Topology.
