Amandla e-hydropower yiteknoloji yamandla avuselelekayo esebenzisa amandla e-kinetic amanzi ukuvelisa umbane. Ngumthombo wamandla acocekileyo asetyenziswa kakhulu onezibonelelo ezininzi, ezinje ngokuhlaziywa, ukukhutshwa okuphantsi, uzinzo kunye nokulawulwa. Umgaqo wokusebenza kwamandla e-hydropower usekelwe kwingcamango elula: ukusebenzisa amandla e-kinetic okuhamba kwamanzi ukuqhuba i-turbine, ethi yona iguqule i-generator ukuvelisa umbane. Amanyathelo okuvelisa amandla e-hydropower ngala: ukuphambuka kwamanzi kwidama okanye emlanjeni, okufuna umthombo wamanzi, ngesiqhelo i-reservoir (indawo yokugcina amanzi eyenziweyo) okanye umlambo wendalo, obonelela ngamandla; isikhokelo sokuhamba kwamanzi, apho ukuhamba kwamanzi kujoliswe kwiiblades ze-turbine ngetshaneli yokuphambuka. Itshaneli yokuphambuka inokulawula ukuhamba kwamanzi ukulungisa amandla okuvelisa umbane; i-turbine iyasebenza, kwaye ukuhamba kwamanzi kubetha iiblades ze-turbine, okubangela ukuba ijikeleze. I-turbine ifana nevili lomoya ekuveliseni umbane womoya; i-generator ivelisa umbane, kwaye ukusebenza kwe-turbine kujikelezisa i-generator, evelisa umbane ngomgaqo wokungenisa umbane nge-electromagnetic; ukuhanjiswa kwamandla, amandla avelisiweyo adluliselwa kwigridi yamandla kwaye anikwe izixeko, amashishini kunye namakhaya. Kukho iintlobo ezininzi zamandla ombane aphuma emanzini. Ngokwemigaqo yokusebenza eyahlukeneyo kunye neemeko zokusetyenziswa, inokwahlulwahlulwa ibe kukuveliswa kwamandla omlambo, ukuveliswa kwamandla edama, ukuveliswa kwamandla olwandle kunye nolwandle, kunye nombane omncinci ophuma emanzini. Amandla ombane aphuma emanzini aneenzuzo ezininzi, kodwa kukho nezinye iingxaki. Iingenelo zezi: amandla ombane aphuma emanzini ngumthombo wamandla avuselelekayo. Amandla ombane axhomekeke ekujikelezeni kwamanzi, ngoko ke avuseleleka kwaye akayi kucinywa; ngumthombo wamandla ococekileyo. Amandla ombane aphuma emanzini akavelisi iigesi zegreenhouse kunye nongcoliseko lomoya, kwaye akanampembelelo ingako kwindalo esingqongileyo; alawuleka. Izitishi zamandla ombane aphuma emanzini zinokulungiswa ngokwemfuno ukuze zibonelele ngamandla omthwalo asisiseko anokuthenjwa. Iingxaki eziphambili zezi: iiprojekthi zamandla ombane amakhulu aphuma emanzini zinokubangela umonakalo kwindalo esingqongileyo, kunye neengxaki zentlalo ezifana nokufuduka kwabemi kunye nokuhluthwa komhlaba; amandla ombane aphuma emanzini athintelwe kukufumaneka kwezixhobo zamanzi, kwaye ukoma okanye ukuncipha kokuhamba kwamanzi kunokuchaphazela amandla okuvelisa umbane.
Amandla ombane ahlaziyiweyo, njengohlobo lwamandla avuselelekayo, anembali ende. Iiturbine zamanzi zokuqala kunye namavili amanzi: Kwasekuqaleni kwenkulungwane yesi-2 BC, abantu baqala ukusebenzisa iiturbine zamanzi kunye namavili amanzi ukuqhuba oomatshini abanjengeemill kunye neesawmill. Aba matshini basebenzisa amandla e-kinetic okuhamba kwamanzi ukuze basebenze. Ukufika kokuveliswa kombane: Ngasekupheleni kwenkulungwane ye-19, abantu baqala ukusebenzisa izityalo zamandla ombane wamanzi ukuguqula amandla amanzi abe ngumbane. Isikhululo samandla ombane wamanzi sokuqala emhlabeni sakhiwa eWisconsin, e-USA ngo-1882. Ukwakhiwa kwamadama kunye namadama okugcina amanzi: Ekuqaleni kwenkulungwane yama-20, ubungakanani bamandla ombane wamanzi banda kakhulu ngokwakhiwa kwamadama kunye namadama okugcina amanzi. Iiprojekthi zamadama ezidumileyo ziquka iHoover Dam e-United States kunye neThree Gorges Dam eTshayina. Inkqubela phambili kwezobuchwepheshe: Ngokuhamba kwexesha, iteknoloji yamandla ombane wamanzi iye yaphuculwa rhoqo, kubandakanya ukuqaliswa kweeturbines, ii-hydro-generators kunye neenkqubo zolawulo ezikrelekrele, eziphucule ukusebenza kakuhle kunye nokuthembeka kwamandla ombane wamanzi.
Amandla ombane ahlaziyiweyo ngumthombo wamandla ococekileyo novuselelekayo, kwaye uthotho lwawo lweshishini lugubungela amakhonkco aliqela abalulekileyo, ukusuka kulawulo lwemithombo yamanzi ukuya ekudlulisweni kwamandla. Ikhonkco lokuqala kuthotho lwamandla ombane kulawulo lwemithombo yamanzi. Oku kuquka ucwangciso, ukugcinwa kunye nokusasazwa kokuhamba kwamanzi ukuqinisekisa ukuba amanzi anokunikezelwa ngokuzinzileyo kwiiturbines ukuze kuveliswe umbane. Ulawulo lwemithombo yamanzi ludla ngokufuna ukujonga iiparameter ezifana nemvula, isantya sokuhamba kwamanzi kunye nenqanaba lamanzi ukuze kwenziwe izigqibo ezifanelekileyo. Ulawulo lwemithombo yamanzi lwanamhlanje lukwagxila ekuzinzeni ukuqinisekisa ukuba amandla okuvelisa umbane anokugcinwa nakwiimeko ezinzima njengembalela. Amadama kunye neendawo zokugcina amanzi zizinto ezibalulekileyo kuthotho lwamandla ombane. Amadama adla ngokusetyenziselwa ukuphakamisa amanqanaba amanzi nokwenza uxinzelelo lwamanzi, ngaloo ndlela kwandisa amandla ombane okuhamba kwamanzi. Amadama asetyenziselwa ukugcina amanzi ukuqinisekisa ukuba ukuhamba kwamanzi okwaneleyo kunokubonelelwa ngexesha lemfuno ephezulu. Uyilo kunye nokwakhiwa kwamadama kufuneka kuqwalaselwe iimeko zejoloji, iimpawu zokuhamba kwamanzi kunye nempembelelo yendalo ukuqinisekisa ukhuseleko kunye nokuzinza. Iiturbines zezona zinto ziphambili kuthotho lwamandla ombane. Xa amanzi ehamba ngeeblades zeturbine, amandla ayo e-kinetic aguqulwa abe ngamandla oomatshini, okwenza iturbine ijikeleze. Uyilo kunye nohlobo lweturbine lunokukhethwa ngokwesantya sokuhamba kwamanzi, isantya sokuhamba kunye nokuphakama ukuze kufezekiswe ukusebenza kakuhle kwamandla. Xa iturbine ijikeleza, iqhuba ijenereyitha edibeneyo ukuze ivelise umbane. Ijenereyitha sisixhobo esibalulekileyo esiguqula amandla oomatshini abe ngamandla ombane. Ngokubanzi, umgaqo wokusebenza wejenereyitha kukukhuthaza umbane ngokusebenzisa intsimi yemagnethi ejikelezayo ukuze kuveliswe umbane otshintshanayo. Uyilo kunye nomthamo wejenereyitha kufuneka kumiselwe ngokwemfuno yamandla kunye neempawu zokuhamba kwamanzi. Amandla aveliswa yijenereyitha yi-alternating current, edla ngokufuna ukucutshungulwa nge-substation. Imisebenzi ephambili ye-substation ibandakanya ukunyuka (ukuphakamisa i-voltage ukunciphisa ukulahleka kwamandla xa umbane udluliselwa) kunye nokuguqula uhlobo lwamandla (ukuguqula i-AC ibe yi-DC okanye ngokuchaseneyo) ukuhlangabezana neemfuno zenkqubo yokuhambisa umbane. Ikhonkco lokugqibela kukudlulisela umbane. Amandla aveliswa yisikhululo samandla adluliselwa kubasebenzisi bamandla ezidolophini, kwimizi-mveliso okanye emaphandleni ngemigca yokuhambisa. Imigca yokuhambisa kufuneka icwangciswe, iyilwe kwaye igcinwe ukuqinisekisa ukuba umbane udluliselwa ngokukhuselekileyo nangokufanelekileyo ukuya kwindawo oya kuyo. Kwezinye iindawo, umbane unokufuna ukucutshungulwa kwakhona ngesitishi esingaphantsi komhlaba ukuze kuhlangatyezwane neemfuno zevolthi ezahlukeneyo kunye neefrequencies.
