I-Wind Turbines Power Curve

 

Ijika lamandla lakhiwa i-Spee Windd njengokuhluka okuzimele (x), tUsebenza amandla asebenzayo njengokuhlukahluka okuthembekile (y) ukusungula uhlelo lokuxhumanisa.Isakhiwo sokuhlakaza isivinini somoya namandla asebenzayo sifakwe ngejika elifanele, futhi ekugcineni ijika elingabonakala ebudlelwaneni phakathi kwejubane lomoya namandla asebenzayo atholakala. Embonini yamandla omoya, ukuhlukunyezwa komoya kwe-1.225kg / m3 kubhekwa njenge-aunsity yomoya ejwayelekile, ngakho-ke ijika lamandla ngaphansi kokuqina komoya okujwayelekile libizwa ngokuthi ijika lamandla ajwayelekile we-turbin yomoyaes.

 

Ngokuya ngejika lamandla, i-Wind Energy Ukusetshenziswa kwe-coefffied ye-turbine yomoya ngaphansi kwamabanga ahlukahlukene omoya angabalwa. I-coeffient esetshenziswayo yamandla e-Wind Energy isho isilinganiso samandla atholwe yi-blade kumandla omoya ageleza ngendiza yonke, okuvame ukuvezwa ku-cp, okungukuthi iphesenti lamandla atholwe yi-turbine yomoya emoyeni. Ngokusho kwethiyori kaBaez, ukusetshenziswa okuphezulu komoya okusetshenziswayo kwamandla e-turbines yomoya kungu-0.593. Ngakho-ke, lapho i-couffition ebaliwe yokusetshenziswa kwamandla e-Wind Energy

 

Ngenxa yendawo eyinkimbinkimbi yensimu epulazini lomoya, imvelo yomoya ihlukile ephuzwini ngalinye, ngakho-ke amajika wamandla alinganisiwe e-turbine ngayinye yomoya epulazini lomoya eligcwalisiwe kufanele ahluke. Kodwa-ke, ocwaningweni olunokwenzeka noma esiteji sokukhethwa kwesayithi elincane, unjiniyela wezinsizakusebenza zomoya, umsunguli we-tubion wesikhungo somsebenzi noma umnikazi angancika kuphela esimweni sokufaka ijika lamandla e-theory noma ijika elinganisiwe elinikezwe ngumenzi. Ngakho-ke, esimweni seziza eziyinkimbinkimbi, kungenzeka ukuthola imiphumela ehlukile kunangemva kokuba ipulazi lomoya lakhiwe.

 

Ukuthatha amahora agcwele njengendlela yokuhlola, kungenzeka ukuthi amahora aphelele asensimini afana namanani abhalwe ngaphambili, kepha amanani wephuzu elilodwa ahluka kakhulu. Isizathu esiyinhloko salokhu kuphambuka okukhulu ekuhlolweni kwezinsizakusebenza zomoya zendawo eyinkimbinkimbi yendawo. Kodwa-ke, ngokombono wamandla we-Power Curve, ijika lamandla okusebenza kwephuzu ngalinye kule ndawo yensimu ihluke kakhulu. Uma ijika lamandla libalwa ngokusho kwalomkhakha, lingase lifane nejika lamandla e-theory elisetshenziswe esikhathini esedlule.

Ngasikhathi sinye, i-Power Curve akuyona ukuguquguquka okukodwa okushintsha ngejubane lomoya, futhi ukuvela kwezingxenye ezahlukahlukene ze-turbine yomoya kuzodala ukuguquguquka kwejika lamandla. Ijika lamandla e-theoretical kanye nejika lamandla alinganisiwe lizozama ukuqeda ithonya lezinye izimo ze-turbine yomoya, kepha ijika lamandla ngesikhathi sokusebenza alikwazi ukungakunaki ukuguquguquka kwejika lamandla.

 

Uma ijika lamandla elilinganisiwe, ijika lamandla (le-theoretical) elinamandla kanye nemibandela yokwakheka okwenziwe ngokusebenza kweyunithi kudidekile, kuphelelwe yindima yokucabanga, ulahlekelwe yindima ye Ijika lamandla, futhi ngasikhathi sinye, kuzovela izingxabano ezingadingekile nokuphikisana.
