Izindlela zokusetha ifrikhwensi ezivamile ze-inverter ikakhulukazi zihlanganisa: ukusetha ikhibhodi yesisebenzisi, ukusetha isignali yokuxhumana, ukusetha isignali ye-analog, ukusetha isignali yokushaya kanye nokusetha imodi yokuxhumana. Lezi zindlela ezinikezwa ama-frequency zinezinzuzo kanye nokubi zazo, ngakho-ke kufanele zikhethwe futhi zisethwe ngokwezidingo zangempela. Ngaleso sikhathi, izindlela ezahlukahlukene ezinikezwe imvamisa zingakhethwa ngokuya ngezidingo zokusebenza zokupakisha nokushintsha.
Imodi yokulawula
I-voltage ephumayo ye-voltage ephansi yokuguqula imvamisa ejwayelekile ingu-380 ~ 650V, amandla okukhiphayo ngu-0.75 ~ 400kW, imvamisa yokusebenza ngu-0 ~ 400Hz, isekethe yayo eyinhloko isebenzisa isekethe ye-ac-dc - ac. Imodi yayo yokulawula idlule ezizukulwaneni ezine ezilandelayo.
Imodi yokulawula ye-Sinusoidal pulse width modulation (SPWM).
Isici salo yisakhiwo sesifunda sokulawula silula, izindleko ziphansi, ubulukhuni besici somshini bubuye buhle, bungagculisa isicelo sokulawulwa kwejubane elijwayelekile lokudlulisa, sisetshenziswe kabanzi kuyo yonke imikhakha yemboni. Kodwa-ke, emazingeni aphansi, ngenxa ye-voltage ephansi yokuphuma, i-torque ithinteka kakhulu ukwehla kwe-voltage yokumelana ne-stator, okunciphisa i-torque ephezulu yokukhipha. Ngaphezu kwalokho, izakhiwo zayo zemishini, ngemuva kwakho konke, ayikho injini yamanje eqondile, futhi ukusebenza kokulawula isivinini se-torque emile nenamandla akugculisi, nokusebenza kwesistimu akuphakeme, ijika lokulawula liyashintsha phezu komthwalo, impendulo ye-torque ihamba kancane. , izinga lokusebenzisa i-torque ye-motor aliphezulu, ijubane eliphansi elinokumelana ne-stator kanye nokuba khona komphumela wesikhathi esifile we-inverter kanye nokuwohloka kokusebenza, ukuzinza okubi. Ngakho-ke, abantu bathuthukise ukulawulwa kwe-vector variable frequency frequency regulation.
Imodi yokulawula i-Voltage space vector (SVPWM).
Ngokwesisekelo somphumela ophelele wesizukulwane se-waveform yezigaba ezintathu, ikhiqiza i-wave waveform yezigaba ezintathu ngasikhathi sinye futhi ilinganisela ithrekhi eyindilinga ezungezayo yamagnetic yegebe lomoya wemoto ngenjongo, futhi ipholigoni yokusika yangaphakathi ilingana nesiyingi. . Ngemuva kokusetshenziswa ekusebenzeni, kuyathuthukiswa, okungukuthi, isinxephezelo semvamisa yethulwa ukuze kuqedwe iphutha lokulawula isivinini. Umthelela wokumelana ne-stator ngesivinini esiphansi uqedwa ngokulinganisa impendulo ye-flux linkage amplitude. I-voltage ephumayo kanye ne-current ivaliwe ukuze kuthuthukiswe ukunemba okuguquguqukayo nokuzinza. Kodwa-ke, kunezixhumanisi eziningi kumjikelezo wokulawula futhi akukho mthethonqubo we-torque owethulwayo, ngakho-ke ukusebenza kwesistimu akuthuthukisiwe ngokuyisisekelo.
Imodi yokulawula i-Vector (VC).
I-Vector control variable frequency regulation regulation, iyi-stator current ye-asynchronous motor ohlelweni lwezigaba ezintathu Ia, Ib, Ic, ngokusebenzisa isigaba sesithathu - ukuguqulwa kwezigaba ezimbili, okulingana nesistimu yezixhumanisi zezigaba ezimbili ezimile, i-ac current Ia1Ib1 futhi ngokucindezela uguquko lokuzungezisa okugxile enkambini ye-rotor, okulingana nezixhumanisi ezijikelezayo ezivumelanayo ze-dc yamanje Im1, i-It1 (i-Im1 ilingana nesasasa elivusa amadlingozi le-dc motor; I-1 ilingana ne-armature current elingana netorque), bese kuba ukulawula inani le-dc motor itholakala ngokulingisa indlela yokulawula ye-dc motor. Empeleni, i-ac motor ilingana ne-dc motor, futhi isivinini kanye nenkundla kazibuthe kulawulwa ngokuzimela. Izingxenye ezimbili ze-torque ne-magnetic field zitholakala ngokulawula ukuxhumana kwe-rotor flux kanye nokubola kwe-stator yamanje. Indlela yokulawula i-vector ibalulekile ekwenzeni i-epoch-making. Kodwa-ke, ekusetshenzisweni okusebenzayo, ukuxhuma kwe-rotor flux kunzima ukubhekwa ngokunembile, izici zesistimu zithinteka kakhulu yimingcele yemoto, futhi ukuguqulwa kwe-vector rotation esetshenziselwa inqubo yokulawula ye-motor ye-dc efanayo kuyinkimbinkimbi, ngakho-ke okwangempela. ukulawula umphumela kunzima ukufeza umphumela omuhle wokuhlaziya.
Imodi yokulawula i-torque eqondile (DTC).
Ngo-1985, u-DePenbrock, uprofesa enyuvesi yase-ruhr eJalimane, waqala ukuphakamisa ubuchwepheshe bokuguqula imvamisa ye-DTC. Ngokwezinga elikhulu, lobu buchwepheshe buxazulula ukushoda kokulawula i-vector, futhi buthuthuka ngokushesha ngombono wokulawula inoveli, ukwakheka kwesistimu olula kanye nokusebenza okuhle kakhulu okuguquguqukayo nokumile. Ubuchwepheshe busetshenziswe ngempumelelo ekudluliselweni kwe-ac yamandla aphezulu we-electric locomotive traction. I-Direct torque control (DTC) ihlaziya ngokuqondile imodeli yezibalo ye-ac motor ohlelweni lokuxhumanisa i-stator futhi ilawula ukuxhumana kazibuthe kanye ne-torque yemoto. Ayidingi i-ac motor ukuthi ilingane ne-dc motor, ngakho-ke igcina izibalo eziningi eziyinkimbinkimbi ekuguquleni kwe-vector. Ayidingi ukulingisa ukulawulwa kwe-dc motor, futhi ayidingi ukwenza lula imodeli yezibalo ye-ac motor ukuze ihlukanise.
I-Matrix intersection - isilawuli se-intersection
I-VVVF frequency conversion, i-vector control frequency conversion kanye ne-direct torque control frequency conversion konke kuyi-ac - dc - ac frequency conversion. Ukushiyeka kwayo okuvamile kuyisici samandla okufakwayo aphansi, i-harmonic yamanje enkulu, isifunda esikhulu se-dc sidinga i-capacitor yokugcina amandla, futhi amandla avuselelekayo awakwazi ukunikezwa emuva kugridi, okungukuthi, akakwazi ukwenza umsebenzi wama-quadrant amane. Ngalesi sizathu, ukuguqulwa kwe-matrix ac-ac frequency kwaba khona. Njengomphumela wokuguqulwa kwemvamisa ye-matrix ac-ac kusindisa isixhumanisi esimaphakathi se-dc, ngaleyo ndlela konga umthamo omkhulu, i-electrolytic capacitor ebizayo. Ingakwazi ukufeza isici samandla we-l, i-sinusoidal input yamanje futhi ingasebenza ngama-quadrants amane, ukuminyana kwamandla wesistimu kukhulu. Yize ubuchwepheshe bungakavuthwa, zisaheha osolwazi abaningi ukuthi babufunde bajule. Ingqikithi yayo ayikona ukulawulwa okungaqondile kwamanje, okulinganayo kokuxhumana kazibuthe, kodwa i-torque iqondile njengenani elilawulwayo okufanele lifinyelelwe. Indlela eqondile yilena:
1. Lawula ukuxhumana kwe-stator flux ngokwethula isibukeli se-stator flux ukuze ubone imodi engenazinzwa yesivinini;
2. Ukuhlonza okuzenzakalelayo (ID) ukuhlonza okuzenzakalelayo kwamapharamitha emoto okusekelwe kumodeli yezibalo enembile yenjini;
3. Bala amanani angempela ahambisana ne-stator impedance, inductance mutual, factor magnetic saturation, inertia, njll. Bala itorque yangempela, ukuxhuma kwe-stator flux kanye nesivinini se-rotor ukuze ulawule isikhathi sangempela;
4. Qaphela isignali ye-PWM ekhiqizwe i-band-band control ngokuxhuma kazibuthe ne-torque, futhi ulawule isimo sokushintsha kwesiguquli.
Udinga ukulawula injini kanye inverter ngokwayo
1) inombolo yezigxobo zenjini. Inombolo evamile yemoto ayikho ngaphezu (ifaneleka kakhulu, ngaphandle kwalokho umthamo we-inverter uzokwenyuka ngokufanele.
2) izici ze-torque, i-torque ebalulekile kanye ne-torque esheshayo. Endabeni yamandla afanayo emoto, uma kuqhathaniswa nemodi ye-torque ephezulu, ukucaciswa kwe-inverter kungakhethwa kuyo.
3) ukuhambisana kwe-electromagnetic. Ukuze kuncishiswe ukuphazamiseka kokunikezwa kwamandla okuyinhloko, i-reactor ingangezwa kumjikelezo ophakathi noma umjikelezo wokufaka we-inverter, noma i-pre-isolation transformer ingafakwa. Ngokuvamile, lapho ibanga eliphakathi kwenjini nesiguquli sefrikhwensi lingaphezu kwama-50m, i-reactor, isihlungi noma ikhebula lokuvikela isihlangu kufanele lixhunywe phakathi kwakho.
Ukuguqulwa kwemvamisa ye-Matrix ac-ac kunempendulo yetorque esheshayo (<2ms), ukunemba kwesivinini esiphezulu (±2%, akukho mpendulo ye-PG), kanye nokunemba kwetorque ephezulu (<+3%). Ngesikhathi esifanayo, ine-torque ephezulu yokuqala nokunemba okuphezulu kwe-torque, ikakhulukazi ngesivinini esiphansi (kufaka phakathi isivinini esingu-0), ingakhipha i-torque engu-150% ~ 200%.
Khetha uhlobo lwe-inverter, ngokuya ngohlobo lwemishini yokukhiqiza, ibanga lejubane, ukunemba kwejubane elimile, i-torque yokuqala, inqume ukukhetha imodi yokulawula inverter efaneleke kakhulu. Okubizwa ngokuthi okulungile kokubili kulula ukuyisebenzisa, kodwa futhi kwezomnotho, ukuze kuhlangatshezwane nezimo eziyisisekelo kanye nezidingo zenqubo nokukhiqiza.
