Amandla weTidal wuhlobo lwamandla avuselelekayo, njengoba igama lawo liphakamisa, asebenzise ngokunenzuzo umehluko olwandle oludalwe amagagasi ukuthola amandla. Kodwa-ke, luhlobo lwamandla avuselelekayo olusathuthukiswa kancane kakhulu ngenxa yokukhiqizwa kwalo okuphansi nobunzima balo ekutholeni amandla ngendlela enenzuzo.
Kodwa-ke, ngenxa yephrojekthi exhaswa ngezimali ezivela e-European Union, i-FLOTEC ikwazile ukukhiqiza i-turbine yokuthola amandla kumagagasi ngomsebenzi ocishe ufane kakhulu nowezinjini zomoya ezingasolwandle. Lokhu kuyirekhodi emlandweni wamandla avuselelekayo futhi, ngaphezu kwakho konke, izindaba ezinhle zokukhiqizwa kwamandla okuhlanzekile kwesikhathi esizayo.
Ukwenziwa kwethenjini esebenza kahle
I-turbine eyenziwe yi-FLOTEC (Floating Tidal Energy Commercialization) ikwazile ukukhiqiza ngaphezu kwe-18MWh (amahora wama-megawatt) esikhathini sokuhlolwa esingaphazanyiswa samahora angama-XNUMX. Le mpumelelo isho ukuthi amandla olwandle angazinza ezimakethe zamandla zamandla avuselelekayo zomhlaba wonke ngoba icishe isebenze njengomoya ophephela ogwini olwandle.
Amandla akhiqizwa ngamagagasi angatholakala ngendlela efanayo naleyo eyenziwe ngamapulazi omoya asogwini, kepha ngama-turbine acwiliswe emanzini. Ngale ndlela, sibonga ukuminyana kwamanzi okuphezulu uma kuqhathaniswa nomoya, kungenzeka ukusizakale ngokuhamba kwamanzi akhiqizwa amagagasi.
Amandla weTidal anamandla amakhulu wamandla uma athuthukiswa futhi ephenywa ngokuphelele. Kodwa-ke, kuze kube manje, amandla ayo awakaguquki nakancane uma kuqhathaniswa neminye imikhakha yamandla avuselelekayo afana nelanga nomoya. Lokhu kungenxa yokuthi iqiniso lokuthi imvelo yasolwandle idinga ukuthi izindawo zokukhiqiza amandla ziqine ngokwengeziwe, zimelane nokugqwala okukhiqizwa usawoti, zingabi nemithelela ezilwaneni zasolwandle nasezimileni, ukuze zimelane nezehlakalo zesimo sezulu esibi kakhulu, njll. Yingakho ke, ukuthi ukuthuthukiswa kobuchwepheshe kumandla olwandle kubiza kakhulu futhi kunzima ukwedlula konke okunye.
Iphrojekthi Yokuthuthukisa Amandla weTidal
Le phrojekthi ixhaswe ngemali yase-European FLOTEC eyenzelwe ukuthuthukisa nokusebenzisa amandla okuphehla amandla olwandle angaba nawo. Kokubili amandla olwandle, amandla amaza kanye nomoya ogudle ulwandle yizinhlobo zamandla avuselelekayo angasiza ekwenzeni ngcono imvelo, angasiza ekulweni nokuguquka kwesimo sezulu, adale imisebenzi emisha futhi athuthukise kakhulu ubuchwepheshe bokuvuselelwa.
Iphrojekthi izama futhi ukukhombisa ukuthi ukwenziwa ngcono kobuchwepheshe bamandla olwandle kungasiza ekwehliseni izindleko nezingozi, kuthuthukise ukwethembeka kokuphakelwa kwamandla futhi kuthule lolu hlobo lwamandla ohlakeni lwezohwebo ukuze lufakwe kugridi kagesi we-All Europe.
I-turbine yolwandle esetshenzisiwe, ecishe isebenze njenge-turbine yasolwandle, Idizayinelwe ukuhlala iminyaka engaphezu kwengu-20 futhi ingabanjiswa cishe kunoma yiluphi uhlobo lolwandle, inqobo nje uma ingamamitha angama-25 ukujula. Ngo-Ephreli walo nyaka, i-SR2000 turbine yakwazi ukukhiqiza ama-MW amabili wamandla amakhulu. Kodwa-ke, ithimba lephrojekthi belisebenza ukuthuthukisa ukusebenza kahle futhi likwazile ukukhiqiza i-18MWh. Ukuze kuthuthukiswe ukusebenza kwe-turbine, bakhuphule ububanzi be-Rotor ukusuka kumamitha ayi-16 kuye kwangama-20. Lokhu kudale ukuthi kukhuphuke u-50% ekukhiqizeni ugesi. Uhlelo ukuhlolwa kwenziwa e-European Marine Energy Center (EMEC) e-Orkney, eScotland (UK), lapho ubuchwepheshe bokuthengisa buxhunywe kugesi kagesi ka-Orkney ukuthekelisa amandla ngezigaba.
Iphrojekthi iphinde iphenye ukwanda kwamandla nokusebenza kahle kwe-hydrodynamic ukuze kwehliswe izindleko nokulungiswa. Njengoba ukwazi ukubona, lokhu yingqophamlando emlandweni wamandla olwandle, okuzokwenza igebe lokuncintisana namanye amandla avuselelekayo isikhathi ngasinye.
Kukhona amandla ahlanzekile anele ngaphezu kokuhlangabezana nezidingo "zomuntu", into esintula yona "umshini", okwazi ukuwuthola futhi uwugxilise kahle futhi uzuze.
