Ukudibanisa i-Hydroelectric Power Plant kwi-Local Power Grid

Ukudibanisa i-Hydroelectric Power Plant kwi-Local Power Grid
Izityalo zombane osebenza ngamanzi ziyimithombo ebalulekileyo yamandla ahlaziyekayo, zisebenzisa amandla e-kinetic okuqukuqela okanye ukuwa kwamanzi ukuvelisa umbane. Ukwenza lo mbane usetyenziswe kumakhaya, kumashishini, nakumashishini, umbane owenziweyo kufuneka udityaniswe kwigridi yamandla engingqi. Le nkqubo ibandakanya amanyathelo aphambili aliqela okuqinisekisa ukhuseleko, ukuthembeka, nokusebenza kakuhle.
1. Ukuveliswa koMbane kunye noTshintsho loMbane
Xa amanzi ehamba kwi-injini yombane wamanzi, ijikelezisa ijenereyitha evelisa umbane, ngokuqhelekileyo kwinqanaba lamandla ombane aphakathi (umz., 10–20 kV). Nangona kunjalo, i-voltage kweli nqanaba ayifanelekanga ukuhanjiswa komgama omde okanye ukuhanjiswa ngokuthe ngqo kubathengi. Ngoko ke, umbane uthunyelwa kuqala kwi-transformer ye-step-up, eyandisa i-voltage kwizinga eliphezulu (umzekelo, i-110 kV okanye ngaphezulu) ukuhanjiswa ngokufanelekileyo.
2. UQhagamshelwano lweGrid ngokusebenzisa iziKhululo

Umbane one-voltage ephezulu ugqithiselwa kwisitishi esikufutshane, esisebenza njengonxibelelwano phakathi kweplanti yokuvelisa amanzi kunye negridi yengingqi okanye yendawo. Kwisikhululo esingaphantsi, i-switchgear kunye ne-relays ezikhuselayo zihlola kwaye zilawula ukuhamba kombane. Ukuba umzi-mveliso we-hydro unikezela ngombane kwigridi yendawo, amandla ombane anokwehliswa kwakhona kusetyenziswa ii-transformers ngaphambi kokungena kwinkqubo yokuhambisa.
3. Ungqamaniso neGridi
Phambi kokuba umzi-mveliso wombane ophehlwa ngamanzi uhambise umbane kwigridi, imveliso yawo kufuneka idityaniswe nombane wegridi, amaza, kunye nesigaba. Eli linyathelo elibalulekileyo, njengoko naluphi na ukungalingani kunokubangela ukungazinzi okanye umonakalo kwinkqubo. Ulungelelwaniso lufezekiswa ngokusebenzisa iinkqubo zokulawula ezizenzekelayo ezihlala zibeka iliso kwigridi kwaye zilungelelanise ukusebenza kwejeneretha ngokufanelekileyo.
4. Ukulayisha ukulinganisa kunye nokuThumela
I-Hydropower isoloko isetyenziselwa ukulinganisa umthwalo ngenxa yokuguquguquka kwayo kunye nexesha lokuphendula ngokukhawuleza. Abaqhubi begridi bathumela amandla ombane owenziwe ngamanzi ngokwemfuno, bewavumela ukuba ancedise imithombo ephakathi enjengomoya kunye nelanga. Unxibelelwano lwexesha langempela phakathi kwesityalo kunye neziko lolawulo lwegridi liqinisekisa ukwabelana ngomthwalo kunye nokuzinza kwegridi.
5. IiNkqubo zoKhuselo kunye nokuBeka iliso
Ukuthintela iimpazamo okanye ukungaphumeleli, zombini isityalo kunye negridi zixhotyiswe ngeenkqubo zokubeka esweni kunye nokukhusela. Ezi ziquka ii-circuit breakers, i-voltage regulators, kunye ne-SCADA (uLawulo loLawulo nokuFumana iDatha). Xa kukho impazamo, ezi nkqubo zinokuhlukanisa amacandelo achaphazelekayo kwaye zithintele ukungaphumeleli kwe-cascade.

Ukuqukumbela
Ukudibanisa umzi-mveliso wombane ophehlwa ngamanzi kwigridi yasekhaya yinkqubo entsonkothileyo kodwa eyimfuneko yokuzisa amandla acocekileyo eluntwini. Ngokulawula ngononophelo amanqanaba ombane, ulungelelwaniso, kunye nokhuseleko lwenkqubo, izityalo ezisebenza ngamanzi zinokudlala indima ethembekileyo nezinzileyo kumxube wamandla wale mihla.
