Umsantsa womoya ongalinganiyo phakathi kwe-stator kunye ne-rotor (eyaziwa ngokuba yi-"air gap eccentricity") kwii-hydro-generators ezinkulu yindlela yokuphosakala okukhulu enokuba nemiphumo emibi emininzi ekusebenzeni okuzinzileyo kunye nobomi beyunithi.
Ngamazwi alula, umsantsa womoya ongalinganiyo ubangela usasazo lwentsimi yemagnethi engalinganiyo, nto leyo ebangela uthotho lweengxaki ze-electromagnetic kunye ne-mechanical. Apha ngezantsi sihlalutya ngokweenkcukacha impembelelo kwi-stator current kunye ne-voltage, kunye neminye imiphumo emibi enxulumene nayo.
I. Impembelelo kwiStator Current
Le yeyona mpembelelo icacileyo nethe ngqo.
1. Ukwanda kokuguquguquka kwamandla angoku kunye ne-Waveform
Umgaqo: Kwiindawo ezinezikhewu zomoya ezincinci, ukumelana nemagnethi kuncinci kwaye uxinano lwe-magnetic flux lukhulu; kwiindawo ezinezikhewu zomoya ezinkulu, ukumelana nemagnethi kukhulu kwaye uxinano lwe-magnetic flux luncinci. Le ntsimi yemagnethi engalinganiyo ibangela amandla e-electromotive angalinganiyo kwii-stator windings.
Ukusebenza: Oku kubangela ukungalingani kwimijelo ye-stator yesigaba esithathu. Okubaluleke ngakumbi, inani elikhulu lee-harmonics eziphezulu, ngakumbi ii-harmonics ezingaqhelekanga (ezifana ne-3rd, 5th, 7th, njl.njl.), zifakwa kwi-current waveform, nto leyo ebangela ukuba i-current wave ingabi yi-smooth sine wave kodwa ijijeke.
2. Ukuveliswa kweeComponents zangoku ezineeFrequencies eziKhethekileyo
Umgaqo: Intsimi yemagnethi ejikelezayo engaqhelekanga ilingana nomthombo wemodyuli ophantsi olawula umbane wefrequency yamandla asisiseko.
Ukusebenza: Iibhendi ezisecaleni ziyavela kwi-stator current spectrum. Ngokukodwa, iinxalenye zefrequency eziphawulekayo ziyavela kumacala omabini e-fundamental frequency (50Hz).
3. Ubushushu obugqithisileyo beendawo ezijikelezileyo
Umgaqo: Izinto ezihambelanayo kwi-current ziyandisa ukulahleka kobhedu (ukulahleka kwe-I²R) kwi-stator windings. Kwangaxeshanye, i-harmonic currents ivelisa ukulahleka okongezelelweyo kwe-eddy current kunye ne-hysteresis kwi-iron core, nto leyo ekhokelela ekulahlekelweni kwe-iron.
Ukusebenza: Ubushushu bendawo be-stator windings kunye ne-iron core bunyuka ngokungaqhelekanga, nto leyo enokudlula umda ovumelekileyo wezinto zokukhusela ubushushu, ikhawulezise ukuguga kwe-insulation, kwaye ide ibangele neengozi zokutsha kwe-short-circuit.
II. Impembelelo kwiStator Voltage
Nangona impembelelo kwi-voltage ingathanga ngqo njengakwi-current, ibaluleke ngokulinganayo.
1. Ukuphambuka kweVoltage Waveform
Umgaqo: Amandla e-electromotive aveliswa yijenereyitha anxulumene ngokuthe ngqo ne-air gap magnetic flux. I-Unegant air gap ibangela ukugqwetheka kwe-magnetic flux waveform, nto leyo ebangela ukuba i-induction stator voltage waveform nayo igqwetheke, iqulethe ii-harmonic voltages.
Ukusebenza: Umgangatho we-output voltage uyancipha kwaye awuseyiyo i-standard sine wave.
2. Ukungalingani kweVolthi
Kwiimeko ezinzima ezingafaniyo, kunokubangela ukungalingani okuthile kwi-voltage ye-output yesigaba sesithathu.
III. Ezinye Iziphumo Ezimbi Ezingakumbi (Ezibangelwa Ziingxaki Zangoku Nezombane)
Iingxaki zamandla kagesi kunye ne-voltage ezingentla ziya kubangela uthotho lwee-chain reactions, ezidla ngokuba zibulalayo ngakumbi.
1. Ukutsalwa kweMagnetic okungalinganisekanga (UMP)
Esi sesona siphumo siphambili nesiyingozi sokungangqinelani komoya.
​
Umgaqo: Kwicala elinomsantsa womoya omncinci, ukutsalwa kwemagnethi kukhulu kakhulu kunecala elinomsantsa womoya omkhulu. Olu xhulumaniso lwe-net magnetic (UMP) luya kutsala ngakumbi i-rotor iye kwicala elinomsantsa womoya omncinci.
Umjikelo Onobundlongondlongo: I-UMP iya kuzibangela ingxaki yokungabikho komoya olinganayo, yenze umjikelo onobundlongondlongo. Okukhona ubundlongondlongo busiba bukhulu, kokukhona i-UMP iba ​​nkulu; kokukhona i-UMP iba ​​nkulu, kokukhona ubundlongondlongo busiba bukhulu.
Iziphumo:
•Ukwanda kokungcangcazela kunye nengxolo: Le yunithi ivelisa ukungcangcazela okuphindwe kabini (ngokuyintloko amaxesha amabini kune-frequency yamandla, i-100Hz), kwaye amanqanaba okungcangcazela kunye nengxolo ayanda kakhulu.
•Umonakalo kwiMishini kwiZinto: I-UMP yexesha elide iya kubangela ukwanda kokuguguleka kweebheringi, ukudinwa kwejenali, ukugoba kweshaft, kwaye inokubangela ukuba i-stator kunye ne-rotor zikhuhlane (ukungqubana kunye nokungqubana), nto leyo ebangela ukungaphumeleli okukhulu.
2. Ukwanda kokungcangcazela kweyunithi

Imithombo: Ngokuyintloko ivela kwiinkalo ezimbini:
1. Ukungcangcazela kwe-electromagnetic: Okubangelwa kukutsalwa kwe-magnetic okungalinganiyo (UMP), i-frequency inxulumene ne-rotary magnetic field kunye ne-grid frequency.
2. Ukungcangcazela koomatshini: Kubangelwa kukuguguleka kweebheringi, ukungalingani kweshaft kunye nezinye iingxaki ezibangelwa yi-UMP.
Iziphumo: Ichaphazela ukusebenza okuzinzileyo kweseti yonke yejenereyitha (kuquka ne-turbine) kwaye isongela ukhuseleko lwesakhiwo sendlu yamandla.
3. Impembelelo kuQhagamshelo lweGridi kunye neNkqubo yoMbane
Ukuphazamiseka kwe-voltage waveform kunye ne-current harmonics ziya kungcolisa inkqubo yamandla esityalo kwaye zifake kwi-grid, nto leyo enokuchaphazela ukusebenza okuqhelekileyo kwezinye izixhobo kwibhasi enye kwaye ayihlangabezani neemfuno zomgangatho wamandla.
4. Ukusebenza Okunciphileyo kunye Namandla Okuphuma
Ukulahleka okongeziweyo kwe-harmonic kunye nokufudumeza kuya kunciphisa ukusebenza kakuhle kwejenereyitha, kwaye phantsi kwamandla amanzi angenayo afanayo, amandla asebenzayo asebenzayo aya kuncipha.
Isiphelo

Umsantsa womoya ongalinganiyo phakathi kwe-stator kunye ne-rotor kwiijenereyitha ezinkulu ze-hydro ayisiyonto ilula. Iqala njengengxaki ye-electromagnetic kodwa ngokukhawuleza iguqukela kwimpazamo enkulu edibanisa imiba yombane, ye-mechanical, kunye ne-thermal. Ukutsalwa kwe-magnetic okungalinganiyo (UMP) okubangelayo kunye nokungcangcazela okukhulu okubangelwa yizinto eziphambili ezisongela ukusebenza ngokukhuselekileyo kweyunithi. Ke ngoko, ngexesha lokufakwa kweyunithi, ukulungiswa, kunye nokusebenza kunye nokugcinwa kwemihla ngemihla, ukufana komsantsa womoya kufuneka kulawulwe ngokungqongqo, kwaye iimpawu zokuqala zeempazamo ze-eccentricity kufuneka zifunyanwe kwaye ziphathwe ngexesha elifanelekileyo ngokusebenzisa iinkqubo zokubeka esweni kwi-intanethi (ezifana nokungcangcazela, umbane, kunye nokubeka esweni umsantsa womoya).
