3. Uhlelo lokuguqula ukonga amandla ukuze uthole impendulo yokuguqulwa kwefrikhwensi yewintshi yasemayini
Ngemva kokuguqulwa kwesistimu yewintshi yezimayini, injini yomshini wokuphakamisa iwintshi yemayini yayinesivinini esishintshashintsha kakhulu, ithuthukisa kakhulu ukusebenza komshini wokuphakamisa kanye nokunciphisa umthelela omkhulu ezingxenyeni zenjini nemishini. Ngesikhathi esifanayo, impendulo yamandla izothuthukisa amandla okuvuselela enjini azobuyiselwa kugridi, konga kakhulu ugesi, kunciphise izinga lokushisa elizungezile lokusebenza kwemishini esizeni, futhi kwandise impilo yesevisi yezinto zokusebenza zikagesi. Uhlelo lokuvuselela okonga amandla lunamakhabethe amabili okulawula, ahlanganisa isiguquli semvamisa kanye nedivayisi yempendulo yamandla PLC, Imisebenzi ethile ye-contactor nezinye izakhi ifingqiwe kanje:
1. Ngemuva kokuguqulwa kwesistimu, imodi yokulawula impendulo yemvamisa eguquguqukayo yemoto ingashintshwa ngokukhululekile ngemodi yokulawula imvamisa yochungechunge lwe-rotor yasekuqaleni, futhi izindlela ezimbili zokulawula zixhunywe ngogesi ukuze kuqinisekiswe ukuphepha kokusebenza kwesistimu.
2. Ngemuva kokuguqulwa kwesistimu, imodi yokuqala yokusebenza kanye nemikhuba yokuwina imayini kuzogcinwa, okungukuthi, ukulawulwa kwegiya kanye nemodi yokusebenza yesilawuli sokuqala sekhamera kuzogcinwa. Ngale ndlela, ngeke kuthinte ukusebenza okuvamile komqhubi wewintshi yezimayini futhi kuqinisekiswe ukuthi ukuhlolwa kwemishini ekhethekile yewintshi yezimayini kuyafaneleka.
3. Isistimu yokulawula imvamisa yokushintshashintsha kagesi yendlela yokuphakamisa inemisebenzi eminingi yokuvikela efana nesekhethi emfishane, i-overvoltage, i-overcurrent, ukulahleka kwesigaba, ukulayishwa okungaphezulu, kanye nezinga lokushisa elingaphezulu, ukuze kukhuliswe ukuvikeleka kwendlela yokuphakamisa iwintshi yemayini.
4. Uhlelo lwamukela isiguquli sefrikhwensi ukuze sishayele umshini wokuphakamisa. Lapho injini ishayela umthwalo ongase wehliswe, injini izoba sesimweni sokukhiqiza amandla kabusha. Idivayisi yempendulo yamandla izobuyisela amandla avuselelwe enjini esimeni sokukhiqiza kugridi yamandla, iqinisekise ukusebenza okuvamile kwesistimu yefrikhwensi eguquguqukayo futhi yonga kakhulu ugesi.
4. Ukulungisa iphutha lesistimu
① Ukulungiswa kwamaphutha kwezinhlelo ze-PLC namasekhethi okulawula. Ngemuva kokuthi ukufakwa kwemishini sekuqediwe, isifunda sokulawula sinikwa amandla futhi isifunda esikhulu asivulwanga. Yenza umjikelezo wokulawula kanye nokulungisa iphutha lohlelo lwe-PLC ukuze uqinisekise ukulawulwa okunengqondo okulungile kwesekethe yokulawula ne-PLC, kanye nokusebenza okuvamile kwazo zonke izingxenye.
② Ukulungiswa kwamaphutha kwesiguquli semvamisa.
Nqamula injini yokuwina imayini kusinciphisi, futhi usebenzise imodi yokulawula ye-V/F ukuze ungalayishi umsebenzi wesiguquli sefrikhwensi. Hudula injini ukuze uqinisekise ukusebenza okuzinzile nokujwayelekile kwenjini, futhi i-voltage ephumayo kanye neyamanje yesiguquli sefrikhwensi kujwayelekile.
Nqamula injini yokuwina imayini kusinciphisi, bese usebenzisa indlela ye-PG yokulawula i-vector yamahhala ukuze isiguquli sefrikhwensi senze ukuzifundela okujikelezayo nokuthola amapharamitha emoto. Bese, indlela yokulawula i-vector yamahhala ye-PG isetshenziselwa ukusebenza okungalayishiwe, ukuhudula injini nokulungisa amapharamitha ahambisanayo ukuze kuqinisekiswe ukusebenza okuzinzile kwemoto. I-voltage ephumayo kanye neyamanje yesiguquli sefrikhwensi kuvamile.
Xhuma i-winch motor kusinciphisi, bese usebenzisa isilawuli se-PG samahhala se-vector yesiguquli sefrikhwensi. Qalisa isiguquli sefrikhwensi ngomthwalo ukuze uqinisekise ukusebenza kwemoto okuzinzile.
③ Ukulungiswa kwamaphutha kwedivayisi yempendulo yamandla.
Yenza izivivinyo zokungalayishi nokwehlisa umthwalo osindayo ewindini lezimayini, usethe kahle inani le-voltage yesenzo sempendulo yedivayisi yempendulo yamandla, futhi uqinisekise ukusebenza okuvamile kwesiguquli sefrikhwensi kanye nesistimu yempendulo yamandla.
④ Ingqikithi yokulungisa iphutha nokusebenza kohlelo.
Lonke uhlelo luhlolwa jikelele ukuze kuqinisekiswe ukuthi iwintshi yezimayini iyaphakanyiswa futhi yehliswe ngaphandle komthwalo, iphakanyiswe futhi yehliswe ngaphansi komthwalo osindayo, isivinini segiya ngalinye sihlangabezana nezidingo, amashifu avamile, futhi isiguquli sefrikhwensi kanye nedivayisi yempendulo yamandla isebenza ngokujwayelekile. Futhi yenza ukuhlolwa kokushintshwa kokuguqulwa komsebenzi kanye nemvamisa ukuqinisekisa ukushintshwa okujwayelekile kanye nokusebenza okujwayelekile kwemvamisa yamandla.
4, Umthelela Wesicelo kanye Nokuhlolwa Kwekhasimende Kwempendulo Yokuguqulwa Kwemvamisa ye-IPC Yesistimu Yokulawula Ugesi Ekulondolozeni Amandla Ukuvuselela Amawintshi Emayini
Ukusebenza kwangempela kwesistimu kufakazele ukuthi ukusetshenziswa kwesistimu yokulawula imvamisa ye-IPC yempendulo kagesi ekuvuseleleni okonga amandla amawintshi asemayini akushintshi indlela yokusebenza yasekuqaleni yamawintshi asemayini, futhi ibhuleki lesandla lasekuqaleni ngeke lisasetshenziswa, okwenza umsebenzi ube lula. Uhlelo lusebenza ngokuzinza nangokuthembekile, ngokusebenza okuhle kakhulu kokulawula isivinini kanye ne-torque enkulu yokuqala kanye nokuphuma kwe-torque ephansi; Lapho umshini wehliswa, ugesi owedlulele okhiqizwa amandla kagesi avuselelwayo ubuyiselwa kugridi, okonga kakhulu amandla. Ikhasimende laneliseke kakhulu ngokusebenza ngempumelelo kwesistimu yokulawula imvamisa ye-IPC ye-IPC ekuvuseleleni okonga amandla kwamawintshi asemayini. Ngemuva kokulinganisa kwangempela, isistimu yokulawula i-IPC variable frequency feedback electronic control ingasindisa ngaphezu kuka-28% wamandla kagesi uma kuqhathaniswa nendlela yokulawula isivinini sokumelana nesivinini se-winch ye-winch motor rotor.
5. Isiphetho
Ukusetshenziswa kwe-IPC frequency conversion feedback system electronic control control ekuguquleni ukonga amandla kumawintshi asemayini kuye kwathuthukisa izinga lokuzishintsha kwemishini yokuwina embonini yezimayini futhi kwasheshisa ukuthuthukiswa kwemishini yezimboni embonini yezimayini. Ibambe iqhaza elihle kakhulu ekwenzeni ngcono umthamo wokukhiqiza wemboni yezimayini kanye nokuqinisekisa ukukhiqizwa kwayo kokuphepha.
Okubaluleke nakakhulu, izisetshenziswa zewintshi eziphakamisa imayini zingezamathuluzi ezimayini ezinkulu, futhi ukusetshenziswa kwawo kwamandla kubala ingxenye enkulu yawo wonke amandla asetshenziswayo kuwo wonke ukukhiqizwa kwezimayini. Uma kuqhathaniswa nesistimu yokulawula isivinini sokumelana ne-rotor yesilonda, isistimu yokulawula imvamisa yempendulo kagesi ingawonga kakhulu ugesi, inciphise ngempela izindleko zokukhiqiza futhi ikhiqize izinzuzo zezomnotho embonini yezimayini.
