Abukho ubudlelwano obuqondile phakathi kwefrikhwensi ye-AC kanye nesivinini senjini sesiteshi samandla aphehlwa ngamanzi, kodwa kunobudlelwano obungaqondile.
Kungakhathaliseki ukuthi hlobo luni lwemishini yokuphehla ugesi, ngemva kokukhiqiza ugesi, idinga ukuhambisa ugesi kugridi yamandla, okungukuthi, i-generator idinga ukuxhunywa kugridi ukuze iphehle ugesi. Uma igridi yamandla ibe nkulu, iba yincane ibanga lokuguquguquka kwefrikhwensi, futhi izinza zizinzile. Ifrikhwensi yegridi ihlobene kuphela nokuthi amandla asebenzayo alinganiselwe yini. Uma amandla asebenzayo akhishwa isethi yejeneretha emakhulu kunamandla asebenzayo kagesi, imvamisa iyonke yegridi yamandla izokhula. ,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. Kunjalo, amandla amakhulu aphehlwa ngamanzi eMigobho Emithathu Ukusetshenziswa okuyinhloko ukukhiqiza ugesi. Uma kuqhathaniswa nezinye izinhlobo zeziteshi zikagesi, iziteshi eziphehla amandla kagesi zinezinzuzo ezikhona ekulawulweni kwamaza. I-hydro turbine ingakwazi ukulungisa ngokushesha isivinini, engalungisa ngokushesha ukuphuma okusebenzayo nokusebenzayo kwejeneretha, ukuze ilinganise ngokushesha umthwalo wegridi, kuyilapho amandla ashisayo namandla enuzi, njll., ilungisa okukhiphayo kwenjini ukuze kube kancane Kakhulu. Uma nje amandla asebenzayo egridi elinganiswe kahle, i-voltage izinzile. Ngakho-ke, isiteshi sikagesi esiphehlwa ngamanzi sinegalelo elikhulu ekuzinzeni kwefrikhwensi yegridi.
Njengamanje, izimboni eziningi zikagesi ezincane neziphakathi nendawo ezweni zingaphansi kwegridi kagesi, futhi igridi yamandla kufanele ibe nokulawula okuphelele phezu kwezitshalo zamandla ezishintsha imvamisa, ukuze kuqinisekiswe ukuzinza kwefrikhwensi yegridi yamandla kanye ne-voltage. 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 ama-electrode angu-n, ingu-3000/n revolutions ngomzuzu. Isondo lamanzi kanye nejeneretha ngokuvamile kuxhunywa ndawonye ngenye indlela yokudlulisa isilinganiso esinqunyiwe, ngakho-ke kungashiwo ukuthi kunqunywa nobuningi begridi.
2. Iyini indima yomshini wokulungisa amanzi? Lungisa okukhiphayo 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 imvamisa 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 esivinini esilinganiselwe liye izikhathi eziningana, futhi kulula ukubangela ingozi esheshayo!
3. Amandla akhiqizwa ijeneretha azophinde athinte imvamisa yegridi, futhi iyunithi kagesi ngamanzi ngokuvamile isetshenziswa njengeyunithi yokumodela imvamisa ngenxa yezinga eliphezulu lokulawula uma kuqhathaniswa.
