Ukusebenzisa Amandla Omoya: Ukuhlolwa Okuqhutshwa Yidatha Ye-FRP (I-Fiber Reinforced Polymer) Ekukhiqizeni I-Wind Turbine Blade

Abstract:

Emzamweni wokuthola amandla esimeme, izinjini zomoya sezivele zagqama. Njengoba imboni ithuthuka, ukukhethwa kwezinto zokwakha ama-turbine blades kudlala indima ebalulekile ekusebenzeni kahle nasekuphileni isikhathi eside. Lesi sihloko, esisekelwe ebufakazini obunamandla, sigqamisa izinzuzo eziningi ze-FRP (I-Fiber Reinforced Polymer) ekwenziweni kwensingo ye-wind turbine blade, igcizelela ukuphakama kwayo ngaphezu kwezinto ezivamile.

1. Inguquko Emandleni Nokuqina:

Isilinganiso samandla nesisindo:

I-FRP: Inkulu ngokumangalisayo izikhathi ezingama-20 kunensimbi.

I-Aluminium: Izikhathi ezi-7-10 kuphela kunezensimbi, ngokuya ngengxubevange ethile.

Uma kubhekwa ukuthi ama-wind turbine blades kufanele abe namandla kodwa angasindi ukuze kuthuthukiswe ukusebenza kwe-aerodynamics nokusekelwa kwesakhiwo, isilinganiso esimangalisayo samandla nesisindo se-FRP sivela njengokuhamba phambili okucacile.

2. Ukulwa Nezitha Zemvelo: Ukugqwala Nokumelana Nesimo Sezulu:

Okutholakele ekuhlolweni kwenkungu kasawoti (ASTM B117):

Insimbi, nakuba iqinile, ibonisa izimpawu zokugqwala ngemva nje kwamahora angu-96.

I-Aluminiyamu izwa i-pitting post amahora angu-200.

I-FRP ihlezi iqinile, ingenakho ukucekelwa phansi ngisho namahora ayi-1,000 edlule.

Ezimweni ezineziyaluyalu lapho kusebenza khona izinjini zomoya, ukumelana nokugqwala okungenakuqhathaniswa kwe-FRP kuqinisekisa ubude besikhathi be-blade enwetshiwe, kuncishiswe ukulondolozwa kanye nezikhawu zokushintshwa.

3. Ukungavumeli Ukukhathala:

Ukuhlolwa kokukhathala ezintweni ezingaphansi kwengcindezi yomjikelezo:

I-FRP ihlale idlula izinsimbi, ikhombisa impilo yokukhathala ephakeme kakhulu. Lokhu kuqina kubalulekile kuma-wind turbine blade, ahlangabezana nemijikelezo yengcindezi engenakubalwa phakathi nesikhathi sokusebenza kwawo.

4. Ukusebenza Kwe-Aerodynamic kanye Nokuvumelana nezimo:

Imvelo ethambile ye-FRP ivumela ukunemba ekwenzeni amaphrofayili e-aerodynamically blade. Lokhu kunemba kuthinta ngokuqondile ukusebenza kahle kokuthwebula amandla, okuholela kumaturbine asebenzisa amandla omoya engeziwe imitha ngalinye lobude be-blade.

5. Imithelela Yezomnotho Ngokusetshenziswa Okunwetshiwe:

Izindleko zeminyaka eyi-10 zokulungisa nokushintsha:

Izindwani zensimbi ne-aluminium: Cishe u-12-15% wezindleko zokuqala, kucatshangelwa ukwelashwa, ukulungiswa, nokushintshwa.

Ama-FRP blades: I-3-4% nje yezindleko zokuqala.

Uma kubhekwa ukuqina kwe-FRP, ukumelana nezingcindezi zemvelo, kanye nezidingo zokunakekelwa okuncane, izindleko zayo eziphelele zobunikazi ziba phansi kakhulu ngokuhamba kwesikhathi.

6. I-Eco-Friendly Manufacturing kanye ne-Lifecycle:

CO₂Okuphumayo Ngesikhathi Sokukhiqiza:

Ukukhiqiza kwe-FRP kukhipha i-CO engaphansi ngo-15%.₂kunensimbi futhi ingaphansi kakhulu kune-aluminium.

Ukwengeza, ubude besikhathi esinwetshiwe kanye nokuncipha kwemvamisa yokushintshwa kwama-FRP kusho ukungcola okuncane kanye nomthelela oncishisiwe wemvelo phezu komjikelezo wokuphila we-turbine.

7. Okuqanjwe kabusha ku-Blade Design:

Ukuzivumelanisa nezimo kwe-FRP kusiza ukuhlanganiswa kwezinzwa kanye nezinhlelo zokuqapha ngokuqondile esakhiweni se-blade, okuvumela ukuqapha ukusebenza kwesikhathi sangempela nokugcinwa okumatasa.

Isiphetho:

Njengoba imizamo yomhlaba wonke ishintshela ezixazululweni zamandla esimeme, izinto ezikhethwa ekwakhiweni kwezinjini zomoya ziba phambili. Ngokuhlaziya okuphelele okuqhutshwa yidatha, ukufaneleka kwe-FRP ekukhiqizeni i-wind turbine blade kugqanyiswa ngokungananazi. Ngenhlanganisela yayo yamandla, ukuguquguquka, ukuqina, kanye nokucatshangelwa kwemvelo, i-FRP ihlelelwe ukubusa ikusasa lengqalasizinda yamandla omoya, iqhubekisele imboni ekuphakameni okusha kokusebenza kahle nokusimama.
