Isimo sezinjini zomoya eziqandisiwe sithole ukunakwa okukhulu, ikakhulukazi njengoba umhlaba uguqukela emithonjeni yamandla esimeme kakhudlwana. Le ndatshana icubungula inkimbinkimbi yokuthi iqhwa lizithinta kanjani izinjini zomoya, imithelela yokusebenza kahle kwamandla, kanye namasu amasha athuthukiswayo ukuze kuncishiswe lezi zinselele. Ngokuqonda lezi zici, ababambiqhaza emkhakheni wamandla avuselelekayo bangakwazi ukuzulazula kangcono izithiyo ezibangelwa isimo sezulu esibandayo.
Okuqukethwe:
- Ukuqonda umthelela weqhwa kuma-wind turbines
– I-equation yokonga amandla: Ukubala izindleko zamakhaza
- Izixazululo ezintsha zokulwa neqhwa
– Iqhaza lobuchwepheshe ekususeni i-icing
– Ukubheka phambili: Ikusasa lama turbines omoya ezindaweni ezibandayo
Ukuqonda umthelela weqhwa kuma-wind turbines:
Ukunqwabelana kweqhwa kuma-turbines omoya akuyona nje into ekhathazayo ebonakalayo; kuba nomthelela omkhulu ekusebenzeni nokusebenza kahle kwazo. Uma iqhwa lakha ama-blades, lishintsha izici zabo ze-aerodynamic, okuholela ekunciphiseni ukusebenza kahle futhi, kwezinye izimo, ukumisa okuphelele kokusebenza. Ngaphezu kwalokho, isisindo esengeziwe seqhwa singabangela ubunzima bemishini, bubeke izingozi zokuphepha futhi kwandise izindleko zokulilungisa. Lesi sigaba sihlola ukuthi ukwakheka kweqhwa kuzithinta kanjani izinjini zomoya kanye nemithelela ebanzi kumaphrojekthi wamandla avuselelekayo ezindaweni ezibandayo.
Izibalo zokonga amandla: Ukubala izindleko zamakhaza:
Ukuba khona kweqhwa kuma-turbines omoya kwethula okuhlukile okuyinkimbinkimbi kuzibalo zokonga amandla. Ukwehliswa kokusebenza kahle akuthinti nje kuphela umkhiqizo osheshayo wepulazi lomoya kodwa futhi kunomthelela wezezimali esikhathini eside. Le ngxenye ye-athikili ihlola umthelela wezomnotho wokwehla kokusebenza kahle ngenxa ye-icing, okuhlanganisa izindleko zokusebenza ezikhuphukile kanye nokulahlekelwa kwemali engenayo okungaba khona. Ukuqonda lezi zindleko kubalulekile ukuze ababambiqhaza benze izinqumo ezinolwazi mayelana nokutshalwa kwezimali kumaphrojekthi wamandla omoya obandayo.
Izixazululo ezintsha zokulwa nokuqandisa:
Njengoba ibhekene nezinselelo zokunqwabelana kweqhwa, umkhakha wamandla avuselelekayo ububambe iqhaza ekuthuthukiseni izixazululo zokunciphisa le miphumela. Lesi sigaba sigqamisa izindlela eziningi ezintsha, ezihlanganisa ukusetshenziswa kwezimbotshana zokunqanda uqweqwe, ukusetshenziswa kwama-blade ashisayo, kanye nokuqaliswa kwezinhlelo ezisebenzayo zokususa uqweqwe lukaqhwa. Indlela ngayinye inezinzuzo zayo kanye nemikhawulo, futhi ukusebenza kwabo kungahluka ngokusekelwe ezimweni ezithile zemvelo. Ngokuhlola lezi zixazululo, isihloko sinikeza ukukhanya kokuthi imboni izivumelanisa kanjani ukuze kuqinisekiswe ukwethembeka nokusebenza kahle kwezinjini zomoya ezimweni ezibandayo.
Iqhaza lobuchwepheshe ekususeni i-icing:
Intuthuko kwezobuchwepheshe idlala indima ebalulekile ekuxazululeni inkinga yezinjini zomoya eziqandisiwe. Kusukela kuzinzwa eziyinkimbinkimbi ezithola ukwakheka kweqhwa ngesikhathi sangempela kuya ezindleleni ezizenzakalelayo zokususa uqweqwe uqweqwe, ubuchwepheshe buhamba phambili ekulweni neqhwa. Le ngxenye icubungula emisha yakamuva yezobuchwepheshe emkhakheni, idingida ukuthi ikukhulisa kanjani ukuphepha, ukusebenza kahle, nokuphila isikhathi eside kwezinjini zomoya ezisebenza ngaphansi kwezimo ezineqhwa.
Ukubheka phambili: Ikusasa lama-turbines omoya ezindaweni ezibandayo:
Njengoba isidingo samandla avuselelekayo siqhubeka sikhula, ukubaluleka kokuthuthukisa ukusebenza kwenjini yomoya ezindaweni ezibandayo ngeke kugcizelelwe. Lesi sigaba sokuphetha sibonisa inqubekelaphambili eseyenziwe kuze kube manje futhi sibheke phambili entuthukweni yesikhathi esizayo kulo mkhakha. Icabangela amandla ezinto ezintsha, ukuthuthukiswa kwedizayini, kanye nezinguquko zenqubomgomo ukuze kuthuthukiswe ukusebenza kwamandla omoya ezifundeni ezivamise ukubanda.
Isiphetho:
Izinjini zomoya eziqandisiwe zethula isethi eyingqayizivele yezinselelo ekufuneni amandla aqhubekayo. Kodwa-ke, ngenhlanganisela yezixazululo ezintsha, intuthuko yezobuchwepheshe, nocwaningo oluqhubekayo, umkhakha wamandla avuselelekayo wenza igxathu ekunqobeni lezi zithiyo. Njengoba siqhubeka nokuhlola nokusebenzisa amasu asebenzayo okususa uqhwa, ikusasa lamandla omoya ezindaweni ezibandayo libukeka lithembisa, linikeza ukukhanya kwethemba kwendawo yamandla esimeme futhi eqinile.
