Imvamisa ye-AC ayihlobene ngqo nesivinini senjini yesiteshi samandla kagesi, kodwa ihlobene ngokungaqondile.
Kungakhathaliseki ukuthi hlobo luni lwemishini yokuphehla amandla, kuyadingeka ukudlulisa amandla kagesi kugridi yamandla ngemva kokukhiqiza amandla kagesi, 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, imvamisa yegridi yamandla ihlobene kuphela nokuthi amandla asebenzayo alinganiselwe.Uma amandla asebenzayo akhishwa isethi yejeneretha emakhulu kunamandla asebenzayo okusetshenziswa kukagesi, imvamisa iyonke yegridi yamandla izokhuphuka, futhi ngokuphambene nalokho.
Ibhalansi yamandla esebenzayo iyisihloko esikhulu segridi 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, engaphinda ilungise ngokushesha ukuphuma okusebenzayo nokusebenzayo kwejeneretha, ukuze ilinganise ngokushesha umthwalo wegridi, kuyilapho amandla ashisayo namandla enuzi kulungisa ukuphuma kwenjini 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 zokuguquguqula imvamisa 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 n ama-electrode, izungeza i-3000 / N ngomzuzu.I-turbine yamanzi kanye nejeneretha ngokuvamile zixhunywa ndawonye ngokusebenzisa indlela ethile yokudlulisela isilinganiso esinqunyiwe, ngakho-ke kungashiwo ukuthi kunqunywa futhi ifrikhwensi yegridi yamandla.
2. Iyiphi indima edlalwa umshini wokulawula amanzi?Lungisa okukhiphayo kwejeneretha, okungukuthi, amandla athunyelwe i-generator kugridi yamandla.Ngokuvamile, amandla athile ayadingeka ukuze kugcinwe ijeneretha ifinyelele isivinini sayo esilinganiselwe, kodwa uma ijeneretha isixhunywe kugridi, isivinini sejeneretha sinqunywa imvamisa yegridi.Ngalesi sikhathi, sivame ukucabanga ukuthi imvamisa yegridi 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, 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.
