Imboni yamandla omoya ikakhulukazi yakhiwe ukukhiqizwa kwezinto ezingavuthiwe ezikhuphuka nomfula, ukukhiqizwa kwezingxenye ezimaphakathi nomfula kanye nokukhiqizwa kwenjini yomoya, kanye nokusebenza kwepulazi lomoya eliphansi nomfula kanye nokusebenza kwegridi yamandla.I- Wind turbine yakhiwa ikakhulukazi i-impeller, igumbi lenjini nombhoshongo.Njengoba umbhoshongo ngokuvamile ungaphansi kokunikezwa amabhidi ahlukene ngesikhathi sokubhida kwepulazi lomoya, i-wind turbine isho impeller negumbi lenjini ngalesi sikhathi.I-impeller ye-fan inesibopho sokuguqula amandla omoya abe amandla emishini.Yakhiwe ngama-blades, ihabhu kanye ne-fairing.Ama-blades aguqula amandla e-kinetic omoya abe amandla omshini wama-blades kanye ne-main shaft, bese abe amandla kagesi ngokusebenzisa ijeneretha.Usayizi nokuma kwe-blade kunquma ngokuqondile ukusebenza kahle kokuguqulwa kwamandla, kanye namandla eyunithi nokusebenza.Ngakho-ke, i-wind turbine blade isendaweni eyinhloko ekwakhiweni kwe-wind turbine.
Izindleko zama-blade amandla omoya zibalelwa ku-20% - 30% wesamba sezindleko zalo lonke uhlelo lokuphehla amandla omoya.Izindleko zokwakha ipulazi lomoya zingahlukaniswa ngezindleko zemishini, izindleko zokufaka, ubunjiniyela bokwakha nezinye izindleko.Uma sithatha ipulazi lomoya elingu-50MW njengesibonelo, cishe u-70% wezindleko uvela ezindlekweni zemishini;U-94% wezindleko zemishini uvela ezintweni zokuphehla ugesi;U-80% wezindleko zemishini yokuphehla ugesi uvela ezindlekweni zeturbine yomoya kanye no-17% ezindlekweni zombhoshongo.
Ngokwalokhu kubala, izindleko zenjini yomoya zibalelwa ku-51% wesamba sokutshalwa kwezimali kwesiteshi sikagesi, futhi izindleko zombhoshongo zibalelwa ku-11% wesamba semali etshaliwe.Izindleko zokuthenga kokubili yizindleko eziyinhloko zokwakha ipulazi lomoya.Ama-wind power blades azoba nezici zobukhulu obukhulu, ukuma okuyinkimbinkimbi, izidingo zokunemba okuphezulu, ukusatshalaliswa kobuningi obufanayo kanye nokumelana nesimo sezulu esihle.Njengamanje, isilinganiso semakethe yonyaka samandla omoya singama-yuan ayizigidi eziyizinkulungwane eziyi-15-20.
Njengamanje, u-80% wezindleko ze-blade uvela ezintweni ezingavuthiwe, lapho inani eliphelele le-reinforcing fiber, i-core material, i-matrix resin ne-adhesive lidlula ama-85% yenani lenani eliphelele, ingxenye ye-reinforcing fiber kanye ne-matrix resin idlula ama-60% , futhi ingxenye ye-adhesive ne-core material idlula u-10%.I-Matrix resin "ukufakwa" kwayo yonke i-blade, egoqa i-fiber material kanye ne-core material.Inani lezinto ezigoqiwe empeleni linquma inani lempahla ye-matrix, okungukuthi, i-fiber material.
Ngokukhula kwesidingo semakethe sokusebenzisa kahle ama-wind power blades, ukuthuthukiswa kwama-wind power blades kuya ngezinga elikhulu sekuphenduke inkambiso engenakugwemeka.Ngaphansi kobude obufanayo bama-blades, isisindo sezindwani ezisebenzisa i-glass fiber njengesiqiniseko sikhulu kakhulu kunaleso sisebenzisa i-carbon fiber njengesiqiniseko, esithinta ukusebenza nokusebenza kahle kokuguqulwa kwama-wind turbines.
