Ipulazi lomoya elingasolwandle elikhulu kunawo wonke emhlabeni

Ngo-1991, ipulazi lomoya lokuqala eligudle ulwandle lasungulwa, lelo le- Vindeby. Yayifakwe eDenmark, emanzini oLwandle iBaltic, futhi inezinjini zomoya eziyishumi nanye. Ekupheleni konyaka we-2016, amandla afakiwe omoya wasolwandle afinyelela ngaphezulu kwe-9000 (MW). Namuhla, amandla omoya aphesheya kwezilwandle ahlala njengenye yezindawo zokubheja ezicacile zesikhathi esizayo zokuvuselelwa, yize kungakabi ubuchwepheshe obunenzuzo ngokuphelele.

Njengamanje, ipulazi lomoya elingasolwandle elikhulu kunawo wonke elisogwini lwaseKent (eNgilandi). Yize iyipaki enkulu kunazo zonke emhlabeni, abagqugquzeli bayo bahlela ukukhulisa amandla ayo kuze kufike ku-870 MW esigabeni sesibili kulindwe ukuvunywa.


Kusukela uNdunankulu waseBrithani, uDavid Cameron, avule ipulazi lomoya elingasolwandle e ILondon Array ephuma emlonyeni woMfula iThames ngoJulayi 2013, le ngqalasizinda ithathwa njengepulazi lomoya elikhulu kunawo wonke aselwandle elakhiwe kuze kube manje.
Abulawa ngokuqalwa kwenhlangano yezinkampani ezakhiwa amaJalimane Eon, isiDanish Dong kanye nomphakathi womphakathi wokukhuthaza amandla avuselelekayo IMasdar ezinze e-Abu Dhabi, njengamanje isebenza ngokugcwele ikhiqiza amandla anele ukuhlinzeka ngenombolo emangalisayo ye amakhaya ayisigamu sesigidi, ngomthamo ofakiwe we I-630 MW.

Ngemuva kweminyaka emine yokwakhiwa nokutshalwa kwezimali okungaphezulu kwe-Izigidi ezingu-2.200 ama-euro, ipaki yakhiwe Ama-injini omoya angu-175 amaVestas SWT, Lokhu kunabela olwandle okuhlala endaweni engamakhilomitha-skwele ayi-100 ebangeni lamakhilomitha angama-20 ukusuka ogwini lwaseKent, eningizimu-mpumalanga yeNgilandi.

Isilinganiso se- 450 amakhilomitha izintambo zasemanzini kanye iziteshi ezimbili ezingasolwandle, okwenza amandla abe maphakathi namandla akhiqizwa imishini yomoya ngaphambi kokuyihambisa iye emhlabathini ngaphakathi.

Ukuhlanganisa imishini yomoya

Ngokufakwa kweturbine yomoya ngayinye osebeni lolwandle, kuye kwadingeka ukuthi kwakhiwe imeshi ejwayelekile yezinqwaba ezivumelaniswe nezici ezithile zolwandle, ngokujula okuhluka phakathi kwamamitha ama-5 kuye kwangama-25 kuye ngecala. Lezi zisekeli zivumela ukuthi imishini yenjini ngayinye iphakanyiswe IVestas SWT-3.6MW-120 ngenhla kogu lolwandle, ngakolunye uhlangothi, zisebenza njengesisekelo sokudlulisa isisindo saso sifike ku- Amathani we-225 emhlabathini.

Umhlangano wepulazi lomoya wasolwandle

Imishini yomoya ngayinye engu-175 inokuphakama kwe- Amamitha angu-147, Amamitha angu-90 ubukhulu be-Rotor nobude be-blade Amamitha angu-58,5. Ukuthuthwa kwamandla akhiqizwe ngamunye wabo, kukhona 210 km yekhebula lomkhumbi wamanzi elixhuma u-turbine ngamunye neziteshi ezimbili ezingasolwandle, bese zona zixhuma nokufakwa esikhundleni Cleve hill emhlabathini owomile ngokusebenzisa Izintambo ezi-4 ezingama-150 kV efinyelela kufayela le- 220 km yobude.

Ngokwezibalo zabagqugquzeli, ngo-2012 ipulazi lomoya elisogwini olukhona kuze kube yimanje lahlinzeka cishe nge 1,5% kagesi, kodwa nge-London Array lesi sibalo kulindeleke ukuthi sikhuphuke ngaphezu kwe- 5% ngaleyo ndlela ugwema ukuphuma kwe- Amathani we-925.000 i-CO2 yonyaka.

Ukwamukelwa kwamandla omoya njengenye yezinto ezingcolisa kakhulu nokuphepha endaweni yamandla yaseYurophu sekuqala ukudlala indima efanele ekukhiqizweni kwamandla avuselelekayo emhlabeni wonke. Endabeni yomoya wasogwini, amandla akhiqizwa ama-turbine anomthelela omncane ku imvelo, Akudingi ukulahlwa noma ukususwa komhlaba, futhi ukutholakala ngasogwini lolwandle, kunomthelela nolaka oluncane ezilwaneni nohlaza uma kuqhathaniswa nomoya ovamile.

Ukunwetshwa kwesikhathi esizayo

ILondon Array isidlulile obekulindelwe yipulazi lomoya IGesGuMbikude, ingqalasizinda esendaweni efanayo kuze kube manje ibambe isihloko sendawo enkulu kunazo zonke ipulazi lomoya elwandle emhlabeni onamandla afakiwe we I-500 MW. Kepha akupheleli lapho.

Ngombono wokuqhubeka nokuhola umjaho obabazekayo emoyeni wasogwini owenziwe yi-United Kingdom, abagqugquzeli beLondon Array manje bahlose ukukhulisa amandla ayo kusuka ku-630 MW wamanje kuye ku 870. Lesi sigaba sesibili sisalinde ukuvunywa yiziphathimandla ezinamakhono ahlukahlukene, kepha sizohlanganisa leli pulazi lomoya njengelikhulu kunawo wonke ake akhiwa. Kulesi 2017 sizoba nempendulo?
