Wind Turbines Power Curve

 

Ijika lamandla lakhiwe ukushwiba komoyad njengokuguquguquka okuzimele (X), tAmandla asebenzayo asebenza njengokuhlukahluka okuncikile (Y) ukuze kusungulwe uhlelo lokuxhumanisa.Isiqephu sokuhlakaza sesivinini somoya namandla asebenzayo sifakwe ijika elifanele, futhi ekugcineni ijika elingabonisa ubudlelwano phakathi kwesivinini somoya namandla asebenzayo ayatholakala.Embonini yamandla omoya, ukuminyana komoya okungu-1.225kg/m3 kubhekwa njengokuminyana komoya okujwayelekile, ngakho-ke ijika lamandla ngaphansi kokuxineka komoya okujwayelekile libizwa ngokuthi ijika lamandla elijwayelekile le-wind turbin.es.

 

Ngokusho kwejika lamandla, i-coefficient yokusetshenziswa kwamandla omoya ye-turbine yomoya ngaphansi kwebanga elihlukile lesivinini somoya ingabalwa.I-coefficient yokusebenzisa amandla omoya ibhekisela esilinganisweni samandla amuncwa i-blade kumandla omoya ageleza kuyo yonke indiza ye-blade, ngokuvamile avezwa ku-Cp, okuyiphesenti lamandla amuncwa i-wind turbine esuka emoyeni.Ngokombono ka-Baez, isilinganiso esiphezulu sokusetshenziswa kwamandla omoya kwezinjini zomoya ngu-0.593.Ngakho-ke, lapho i-coefficient yokusetshenziswa kwamandla omoya ebaliwe inkulu kunomkhawulo we-Bates, ijika lamandla lingathathwa njengelingelona iqiniso.

 

Ngenxa yemvelo yensimu yokugeleza eyinkimbinkimbi epulazini lomoya, imvelo yomoya ihlukile endaweni ngayinye, ngakho-ke ijika lamandla elilinganiselwe le-wind turbine ngayinye epulazini lomoya eliqediwe kufanele lihluke, ngakho isu lokulawula elihambisanayo nalo lihlukile.Nokho, esifundweni sokungenzeka noma isigaba sokukhetha sesizinda esincane, unjiniyela wensiza yamandla omoya wesikhungo sokuklama noma umkhiqizi weturbine yomoya noma umnikazi angathembela kuphela esimweni sokufaka ijika lamandla elicatshangelwayo noma ijika lamandla elilinganiselwe elinikezwe umenzi.Ngakho-ke, endabeni yezindawo eziyinkimbinkimbi, kungenzeka ukuthola imiphumela ehlukile kunangemva kokwakhiwa kwepulazi lomoya.

 

Uma sithatha amahora agcwele njengombandela wokuhlola, kungenzeka ukuthi amahora agcwele ensimini afana namanani abalwe ngaphambilini, kodwa amanani ephoyinti elilodwa ahluka kakhulu.Isizathu esikhulu salo mphumela ukuchezuka okukhulu ekuhlolweni kwemithombo yomoya yendawo eyinkimbinkimbi yendawo yesayithi.Kodwa-ke, ngokombono wejika lamandla, ijika lamandla okusebenza lephoyinti ngalinye kule ndawo yensimu lihluke kakhulu.Uma ijika lamandla libalwa ngokwale nkambu, ingase ifane nejika lamandla elisetshenziswa enkathini edlule.

Ngesikhathi esifanayo, ijika lamandla alikona okuhlukile okukodwa okushintsha ngesivinini somoya, futhi ukwenzeka kwezingxenye ezihlukahlukene ze-turbine yomoya kubophezelekile kubangele ukushintshashintsha kwejika lamandla.Ijika lamandla etiyetha kanye nejika lamandla elilinganisiwe lizozama ukuqeda umthelela wezinye izimo ze-turbine yomoya, kodwa ijika lamandla ngesikhathi sokusebenza alikwazi ukuziba ukushintshashintsha kwejika lamandla.

 

Uma ijika lamandla elilinganisiwe, ijika lamandla elijwayelekile (ithiyori) kanye nezimo zokubunjwa kanye nokusetshenziswa kwejika lamandla elikhiqizwe ukusebenza kweyunithi kudidekile omunye komunye, nakanjani kubangele ukudideka ekucabangeni, kulahlekelwe indima ijika lamandla, futhi ngesikhathi esifanayo, izingxabano ezingadingekile kanye nokuphikisana kuzovela.
