Wind Turbines Power Curve

 

Mphamvu yopindika imapangidwa ndi mafunde amphepod monga chosiyana chodziyimira pawokha (X), tmphamvu yogwira imagwira ntchito ngati chosinthika chodalira (Y) kukhazikitsa dongosolo logwirizanitsa.Chiwembu chobalalitsa cha liwiro la mphepo ndi mphamvu yogwira ntchito chimayikidwa ndi kolowera koyenera, ndipo pamapeto pake mkombero womwe ungawonetse ubale pakati pa liwiro la mphepo ndi mphamvu yogwira ntchito umapezeka. M'makampani opanga mphamvu zamphepo, kachulukidwe ka mpweya wa 1.225kg/m3 amaonedwa kuti ndi kachulukidwe ka mpweya, kotero mphamvu yokhotakhota pansi pa kachulukidwe ka mpweya imatchedwa mphamvu yopindika ya turbin yamphepo.es.

 

Malinga ndi mapindikidwe amagetsi, mphamvu yogwiritsira ntchito mphamvu yamphepo ya turbine yamphepo pansi pamitundu yosiyanasiyana yama liwiro amphepo imatha kuwerengedwa. Mphamvu yogwiritsira ntchito mphamvu ya mphepo imatanthawuza chiŵerengero cha mphamvu zomwe zimatengedwa ndi tsamba ku mphamvu ya mphepo yomwe imadutsa mundege yonse ya blade, yomwe imasonyezedwa mu Cp, yomwe ndi peresenti ya mphamvu zomwe zimatengedwa ndi turbine ya mphepo kuchokera ku mphepo. Malinga ndi chiphunzitso cha Baez, mphamvu yayikulu yogwiritsira ntchito mphamvu yamphepo yama turbines amphepo ndi 0.593. Choncho, pamene mphamvu yowerengetsera yogwiritsira ntchito mphamvu ya mphepo ndi yaikulu kuposa malire a Bates, mphamvu yokhotakhota imatha kuonedwa kuti ndi yabodza.

 

Chifukwa cha malo ovuta othamanga pamunda wa mphepo, chilengedwe cha mphepo ndi chosiyana pa mfundo iliyonse, kotero kuti mphamvu yoyezera mphamvu yamagetsi amtundu uliwonse wamphepo yamphepo yomalizidwa iyenera kukhala yosiyana, kotero kuti njira yoyendetsera kayendetsedwe kake imakhalanso yosiyana. Komabe, mu kafukufuku wotheka kapena gawo la kusankha malo ang'onoang'ono, injiniya wopangira mphamvu zamphepo kapena wopanga makina opangira makina opangira mphepo kapena mwini wake angangodalira momwe amalowera ndi njira yamphamvu yongoyerekeza kapena njira yokhotakhota yamagetsi yoperekedwa ndi wopanga. Choncho, pankhani ya malo ovuta, n'zotheka kupeza zotsatira zosiyana kusiyana ndi pamene famu yamphepo imamangidwa.

 

Kutenga maola athunthu monga muyeso wowunika, ndizotheka kuti maola athunthu m'mundamo ndi ofanana ndi omwe adawerengedwa kale, koma zikhalidwe za mfundo imodzi zimasiyana kwambiri. Chifukwa chachikulu cha chotsatirachi ndi kupatuka kwakukulu pakuwunika kwa mphamvu za mphepo za malo ovuta a malowa. Komabe, potengera mphamvu yopindika, mphamvu yogwiritsira ntchito pamfundo iliyonse mderali ndi yosiyana kwambiri. Ngati mphamvu yokhotakhota ikuwerengedwa molingana ndi gawoli, ikhoza kukhala yofanana ndi mphamvu yamaganizo yomwe imagwiritsidwa ntchito nthawi yapitayi.

Panthawi imodzimodziyo, phokoso lamagetsi silili losinthika limodzi lomwe limasintha ndi liwiro la mphepo, ndipo zochitika za mbali zosiyanasiyana za turbine ya mphepo zimayenera kuchititsa kusinthasintha kwa mphamvu yamagetsi. Mphepete mwa mphamvu yowunikira ndi mphamvu yoyezera mphamvu idzayesa kuthetsa kukhudzidwa kwa zinthu zina za turbine ya mphepo, koma mphamvu yokhotakhota panthawi yogwira ntchito siyinganyalanyaze kusinthasintha kwa magetsi.

 

Ngati kupindika kwa mphamvu yoyezera, mphamvu yokhazikika (yongopeka) ndi mapangidwe ake ndikugwiritsa ntchito njira yokhotakhota yomwe imapangidwa ndi magwiridwe antchito a unityo yasokonezedwa wina ndi mnzake, ndiye kuti izi zingayambitse chisokonezo m'malingaliro, kutaya gawo la mphamvu yokhotakhota, ndipo nthawi yomweyo, mikangano yosafunikira ndi zotsutsana zidzawuka.
