Imvamisa ye-AC ayihlobene ngqo nesivinini senjini yesiteshi samandla kagesi, kodwa ihlobene ngokungaqondile.
Kungakhathaliseki ukuthi hlobo luni lwemishini yokuphehla amandla, idinga ukudlulisa amandla kugridi yamandla ngemva kokukhiqiza amandla, okungukuthi, i-generator idinga ukuxhunywa kugridi ukuze ikhiqize amandla.Ngemva kokuxhunywa kugridi, ixhunywe negridi yamandla iyonke, futhi amaza kuyo yonke indawo kugridi yamandla afana ncamashi.Uma igridi yamandla ibe nkulu, iba yincane ibanga lokuguquguquka kwefrequency kanye nokuzinza kwefrequency.Nokho, ifrikhwensi yegridi yamandla ihlobene kuphela nokuthi amandla asebenzayo abhalansile yini.Uma amandla asebenzayo akhiqizwa isethi yejeneretha emakhulu kunamandla asebenzayo kagesi, imvamisa iyonke yegridi yamandla izokwanda, futhi ngokuphambene nalokho.
Ibhalansi yamandla esebenzayo iyinkinga enkulu yegridi yamandla.Ngenxa yokuthi umthwalo wamandla wabasebenzisi uhlala ushintsha, igridi yamandla kufanele iqinisekise njalo ukuphuma kokukhiqizwa kwamandla kanye nebhalansi yokulayisha.Inhloso ebalulekile yesiteshi sikagesi ophehlwa ngamanzi ohlelweni lwamandla ukushintshwa kwemvamisa.Kunjalo, amandla amakhulu amakhulu aphehlwa ngamanzi we-Three Gorges asetshenziswa kakhulu ukukhiqiza ugesi.Uma kuqhathaniswa nezinye izinhlobo zeziteshi zikagesi, iziteshi eziphehla amandla kagesi zinezinzuzo ezingokwemvelo ekuguquleni imvamisa.I-turbine yamanzi ingakwazi ukulungisa ngokushesha isivinini, engakwazi futhi ukulungisa ngokushesha ukuphuma okusebenzayo nokusebenzayo kwejeneretha, ukuze ilinganise ngokushesha umthwalo wegridi, kuyilapho amandla ashisayo namandla enuzi kulungisa okukhipha injini kancane kakhulu.Uma nje ibhalansi yamandla esebenzayo yegridi yamandla iyinhle, i-voltage izinzile uma kuqhathaniswa.Ngakho-ke, iziteshi eziphehla ugesi ngamanzi zenza umnikelo omkhulu ekuzinzeni kwemvamisa yegridi yamandla.
Njengamanje, iziteshi eziningi zikagesi ezincane neziphakathi nendawo e-China zingaphansi kwegridi kagesi.Igridi yamandla kufanele ibe nokulawula * * * phezu kwezitshalo zamandla zokushintshwa kwefrikhwensi enkulu, ukuze kuqinisekiswe ukuzinza kwefrikhwensi yegridi yamandla kanye ne-voltage.Kalula nje:
1. Igridi yamandla inquma isivinini semoto.Manje sisebenzisa ama-synchronous motors ukukhiqiza amandla, okungukuthi, izinga lokushintsha lifana negridi yamandla, okungukuthi, izikhathi ezingu-50 ngomzuzwana owodwa.Kujeneretha yesitshalo samandla ashisayo enepheya elilodwa kuphela lama-electrode, izungeza ama-revolution angu-3000 ngomzuzu.Ijeneretha yesitshalo samandla kagesi enamapheya angu-n wama-electrode, izungeza 3000 / N ngomzuzu ongu-1.I-turbine yamanzi kanye nejeneretha ngokuvamile zixhunywa ndawonye ngokusebenzisa indlela ethile yokudlulisela isilinganiso esinqunyiwe, ngakho-ke kungashiwo ukuthi kunqunywa futhi ifrikhwensi yegridi yamandla.
2. Iyini indima yendlela yokulawula amanzi?Lungisa okukhiphayo kwejeneretha, okungukuthi, amandla athunyelwe i-generator kugridi yamandla.Ngokuvamile, amandla athile ayadingeka ukuze kugcinwe ijeneretha ifinyelela kusivinini sayo esilinganiselwe, kodwa uma i-generator isixhunywe kugridi yamandla, isivinini se-generator sinqunywa imvamisa yegridi yamandla.Ngalesi sikhathi, sivame ukucabanga ukuthi imvamisa yegridi yamandla ihlala ingashintshile.Ngale ndlela, lapho amandla e-generator edlula amandla adingekayo ukuze kugcinwe isivinini esilinganiselwe, i-generator ithumela amandla kugridi futhi ithatha amandla ngokuphambene nalokho.Ngakho-ke, lapho injini ikhiqiza amandla ngaphansi komthwalo osindayo, uma inqanyuliwe emotweni, ijubane layo lizokhula ngokushesha lisuka ejubaneni elilinganiselwe liye izikhathi eziningana, elivame ukuba nezingozi ezindizayo!
3. Amandla akhiqizwe ijeneretha azophinde athinte ifrikhwensi yegridi, futhi amayunithi aphehlwa ngamanzi avame ukusetshenziswa njengamayunithi okushintsha imvamisa ngenxa yezinga eliphezulu lokulawula uma kuqhathaniswa.
