Abukho ubudlelwano obuqondile phakathi kwefrikhwensi ye-AC kanye nesivinini senjini sesiteshi sokuphehla amandla ngamanzi, kodwa kukhona ubudlelwano obungaqondile.
Kungakhathaliseki ukuthi hlobo luni lwemishini yokuphehla ugesi, idinga ukudlulisa amandla kugridi ngemva kokukhiqiza ugesi, okungukuthi, i-generator idinga ukuxhunywa kugridi ukuze iphehle ugesi.Uma igridi yamandla ibe nkulu, iba yincane i-frequency yokuguquguquka, kanye nezinzile i-frequency.Ifrikhwensi yegridi ihlobene kuphela nokuthi amandla asebenzayo alinganiselwe yini.Uma amandla asebenzayo akhishwa isethi yejeneretha emakhulu kunamandla asebenzayo kagesi, imvamisa iyonke yegridi yamandla izokwanda.,ngendlela efanayo.
Ibhalansi yamandla esebenzayo iyinkinga enkulu kugridi yamandla.Ngenxa yokuthi umthwalo kagesi wabasebenzisi ushintsha njalo, igridi yamandla kufanele iqinisekise njalo ukuphuma kokukhiqizwa kwamandla kanye nebhalansi yokulayisha.Ukusetshenziswa okubaluleke kakhulu kweziteshi zikagesi ophehlwa ngamanzi ohlelweni lwamandla ukulawulwa kwamafrikhwensi.Inhloso enkulu yokuphehla ugesi ngezinga elikhulu ukukhiqiza ugesi.Uma kuqhathaniswa nezinye izinhlobo zeziteshi zikagesi, iziteshi eziphehla amandla kagesi zinezinzuzo ezikhona ekulawulweni kwamaza.I-hydro turbine ingakwazi ukulungisa ngokushesha isivinini, engakwazi futhi ukulungisa ngokushesha ukuphuma okusebenzayo nokusebenzayo kwejeneretha, ukuze ilinganise ngokushesha umthwalo wegridi, kuyilapho amandla ashisayo, amandla enuzi, njll., ukulungisa okukhiphayo kwenjini kancane kakhulu.Uma nje amandla asebenzayo egridi elinganiswe kahle, i-voltage izinzile.Ngakho-ke, isiteshi sikagesi esiphehlwa ngamanzi sinegalelo elikhulu ekuzinzeni kwefrikhwensi yegridi.
Njengamanje, iziteshi eziningi zikagesi ezincane neziphakathi nendawo ezweni zingaphansi kwegridi yamandla kagesi, futhi igridi kagesi kufanele ibe nokulawula okugcwele phezu kwezitshalo zamandla ezishintshashintshayo eziyinhloko ukuze kuqinisekiswe ukuzinza kwefrikhwensi yegridi yamandla namandla kagesi.kalula nje:
1. Igridi yamandla inquma isivinini semoto.Manje sisebenzisa ama-synchronous motors ukukhiqiza amandla, okusho ukuthi izinga lokushintsha lilingana negridi yamandla, okungukuthi, izinguquko ezingu-50 ngomzuzwana.Kujeneretha esetshenziswa esitshalweni samandla ashisayo esinepheya elilodwa kuphela lama-electrode, ingu-3000 revolutions ngomzuzu.Kujeneretha kagesi enamapheya angu-n ama-electrode, ingu-3000/n revolutions ngomzuzu.Isondo lamanzi kanye nejeneretha ngokuvamile kuxhunywa ndawonye ngenye indlela yokudlulisela isilinganiso esinqunyiwe, ngakho-ke kungashiwo ukuthi kunqunywa nobuningi begridi.
2. Iyini indima yomshini wokulungisa amanzi?Lungisa ukuphuma kwejeneretha, okungukuthi, amandla ijeneretha ewathumela kugridi.Ngokuvamile kuthatha inani elithile lamandla ukugcina i-generator ngesivinini sayo esilinganiselwe, kodwa uma i-generator isixhunywe kugridi, isivinini se-generator sinqunywa i-frequency yegridi, futhi ngokuvamile sicabanga ukuthi i-frequency yegridi ayishintshi. .Ngale ndlela, lapho amandla e-generator edlula amandla adingekayo ukuze kugcinwe isivinini esilinganiselwe, i-generator ithumela amandla kugridi, futhi ngokuphambene nalokho ithatha amandla.Ngakho-ke, lapho injini ikhiqiza amandla ngomthwalo omkhulu, uma inqanyuliwe esitimeleni, ijubane layo lizokhula ngokushesha lisuka ejubaneni elilinganiselwe liye izikhathi eziningana, futhi kulula ukubangela ingozi esheshayo!
3. Amandla akhiqizwe ijeneretha azophinde athinte imvamisa yegridi, futhi iyunithi kagesi ngamanzi ngokuvamile isetshenziswa njengeyunithi yokulinganisa imvamisa ngenxa yezinga eliphezulu lokulawula uma kuqhathaniswa.
