Igebe lomoya elingalingani phakathi kwe-stator ne-rotor (eyaziwa ngokuthi “igebe lomoya elingavamile”) kuma-hydro-generator amakhulu liyimodi yephutha elikhulu elingaba nemiphumela emibi eminingi ekusebenzeni okuzinzile kanye nesikhathi sokuphila kweyunithi.
Kalula nje, igebe lomoya elingalingani libangela ukusatshalaliswa kwensimu yamagnetic engalingani, okubangela uchungechunge lwezinkinga zikagesi kanye nezemishini. Ngezansi sihlaziya ngokuningiliziwe umthelela kumandla kagesi kanye ne-voltage ye-stator, kanye neminye imiphumela emibi ehambisanayo.
I. Umthelela ku-Stator Current
Lona umphumela oqondile kakhulu futhi osobala kakhulu.
1. Ukwanda Kokuhlanekezela Kwamanje Nokwakheka Kwamagagasi
Isimiso: Ezindaweni ezinezikhala zomoya ezincane, ukumelana kwamagnetic kuncane kanti ubuningi be-magnetic flux bukhulu; ezindaweni ezinezikhala zomoya ezinkulu, ukumelana kwamagnetic kukhulu kanti ubuningi be-magnetic flux buncane. Le nsimu yamagnetic engalingani ibangela amandla e-electromotive angalingani kuma-stator windings.
Ukusebenza: Lokhu kubangela ukungalingani emifudlaneni ye-stator yesigaba esithathu. Okubaluleke kakhulu, inani elikhulu lama-harmonics aphezulu, ikakhulukazi ama-harmonics angavamile (njenge-3rd, 5th, 7th, njll.), afakwa kwi-waveform yamanje, okwenza i-waveform yamanje ingabi yi-sine wave ebushelelezi kodwa iphendukezelwe.
2. Ukukhiqizwa Kwezingxenye Zamanje Ezinezimvamisa Ezihlukile
Isimiso: Insimu kazibuthe ejikelezayo engavamile ilingana nomthombo wokuguquguquka kwemvamisa ephansi oguqula ugesi wamandla ayisisekelo.
Ukusebenza: Amabhande aseceleni avela ku-spectrum yamanje ye-stator. Ngokukhethekile, izingxenye zemvamisa ezihlukile zivela kuzo zombili izinhlangothi zemvamisa eyisisekelo (50Hz).
3. Ukushisa Okudlulele Kwendawo Kwama-Windings
Isimiso: Izingxenye ze-Harmonic ku-current zandisa ukulahleka kwethusi (ukulahlekelwa yi-I²R) kwama-stator windings. Ngesikhathi esifanayo, i-harmonic currents idala ukulahleka okwengeziwe kwe-eddy current kanye ne-hysteresis enkabeni yensimbi, okuholela ekulahlekelweni kwensimbi okwandisiwe.
Ukusebenza: Izinga lokushisa lendawo lama-stator windings kanye ne-iron core likhuphuka ngendlela engavamile, okungase kudlule umkhawulo ovumelekile wezinto zokuvikela ukushisa, kusheshise ukuguga kokuvikela ukushisa, futhi kubangele ngisho nezingozi zokusha kwe-short-circuit.
II. Umthelela ku-Stator Voltage
Nakuba umthelela ku-voltage ungaqondile njengaku-current, ubaluleke ngokulinganayo.
1. Ukuhlanekezelwa kwe-Voltage Waveform
Isimiso: Amandla e-electromotive akhiqizwa yijeneretha ahlobene ngqo ne-air gap magnetic flux. I-Unequal air gap ibangela ukuphambuka kwe-magnetic flux waveform, okubangela ukuthi i-inducted stator voltage waveform nayo iphambukiswe, equkethe ama-harmonic voltage.
Ukusebenza: Ikhwalithi ye-voltage yokuphuma iyancipha futhi ayiseyona igagasi elijwayelekile le-sine.
2. Ukungalingani kwe-Voltage
Ezimweni ezinzima ezingalingani, kungabangela izinga elithile lokungalingani ku-voltage yokukhipha yezigaba ezintathu.
III. Eminye Imiphumela Emibi Engathi sína (Ebangelwa Izinkinga Zamanje Nezamandla)
Izinkinga zamandla kagesi kanye ne-voltage ezingenhla zizoqhubeka nokuqala uchungechunge lwezindlela zokusabela zamaketanga, ezivame ukuba yingozi kakhulu.
1. Ukudonsa Okungalingani Kwe-Magnetic (UMP)
Lona umphumela oyinhloko noyingozi kakhulu wokungajwayelekile kwesikhala somoya.
​
Isimiso: Ohlangothini olunesikhala somoya esincane, ukudonsa kukazibuthe kukhulu kakhulu kunohlangothini olunesikhala somoya esikhulu. Lokhu kudonswa kukazibuthe okune-net magnetic (UMP) kuzodonsa i-rotor iye ohlangothini olunesikhala somoya esincane.
Umjikelezo Ononya: I-UMP izozikhulisa inkinga yegebe lomoya elingalingani, yakhe umjikelezo ononya. Lapho ukungafani kukhulu, i-UMP iba ​​nkulu; lapho i-UMP iba ​​nkulu, kulapho ukungafani kukhulu khona.
Imiphumela:
•Ukudlidliza Okukhuphukile Nomsindo: Le yunithi ikhiqiza ukudlidliza okuphindwe kabili okuphindaphindwe imvamisa (ikakhulukazi okuphindwe kabili kunemvamisa yamandla, i-100Hz), futhi amazinga okudlidliza nomsindo anda kakhulu.
•Umonakalo Wemishini Ezingxenyeni: I-UMP yesikhathi eside izobangela ukwanda kokuguga kwamabhereyi, ukukhathala kwejenali, ukugoba kweshafti, futhi ingase ibangele ngisho ne-stator ne-rotor ukuthi zikhuhlane (ukungqubuzana kanye nokushayisana), okuyinto ebangela ukwehluleka okukhulu.
2. Ukudlidliza Kweyunithi Okwandayo

Imithombo: Ngokuyinhloko isuka ezicini ezimbili:
1. Ukudlidliza Kwe-Electromagnetic: Okubangelwa ukudonsa kwe-magnetic okungalingani (UMP), imvamisa ihlobene nensimu ye-magnetic ejikelezayo kanye nemvamisa yegridi.
2. Ukudlidliza Kwemishini: Kubangelwa ukuguguleka kwamabhere, ukungahambisani kahle kweshafti kanye nezinye izinkinga ezibangelwa yi-UMP.
Imiphumela: Ithinta ukusebenza okuzinzile kwesethi yonke yejeneretha (kufaka phakathi i-turbine) futhi isongela ukuphepha kwesakhiwo sendlu yamandla.
3. Umthelela Ekuxhumekeni Kwegridi kanye Nesistimu Yamandla
Ukuphambuka kwesimo samagagasi kagesi kanye nama-harmonics amanje kuzongcolisa uhlelo lwamandla esitshalo futhi kufake igridi, okungase kuthinte ukusebenza okuvamile kweminye imishini ebhasini elifanayo futhi kungahlangabezani nezidingo zekhwalithi yamandla.
4. Ukunciphisa Ukusebenza Kahle kanye Namandla Okukhipha
Ukulahlekelwa okwengeziwe kwe-harmonic kanye nokushisa kuzonciphisa ukusebenza kahle kwejeneretha, futhi ngaphansi kwamandla amanzi afanayo okufaka, ukukhishwa kwamandla asebenzayo okuwusizo kuzoncipha.
Isiphetho

Igebe lomoya elingalingani phakathi kwe-stator ne-rotor kuma-hydro-generator amakhulu akuyona neze into encane. Liqala njengenkinga ye-electromagnetic kodwa liphenduka ngokushesha libe yiphutha elikhulu elihlanganisa izici zikagesi, zemishini, nezokushisa. Ukudonsa okungalingani kwe-magnetic (UMP) okubangelayo kanye nokudlidliza okukhulu okubangelwa yizinto eziyinhloko ezisongela ukusebenza okuphephile kweyunithi. Ngakho-ke, ngesikhathi sokufakwa kweyunithi, ukulungiswa, kanye nokusebenza nokugcinwa kwansuku zonke, ukufana kwegebe lomoya kumele kulawulwe ngokuqinile, futhi izimpawu zokuqala zamaphutha angavamile kumele zitholakale futhi ziphathwe ngesikhathi esifanele ngezinhlelo zokuqapha eziku-inthanethi (njengokuqapha ukudlidliza, ugesi, kanye negebe lomoya).
