Hydropower tseem yog lub ntiaj teb loj tshaj plaws ntawm cov hluav taws xob tauj dua tshiab, tsim dua 4,500 terawatt- teev ib xyoos ib zaug thiab muab li 14% ntawm lub ntiaj teb xav tau hluav taws xob. Raws li lig 2025, kev txhim kho tsis tu ncua ntawm cov cuab yeej tseem ceeb xws li turbines, generators, thiab cov twj tso kua mis tau txhim kho kev ua tau zoo, txo cov kev cuam tshuam ib puag ncig, thiab pab sib koom ua ke ntau cua thiab hnub ci rau hauv daim phiaj. Cov thev naus laus zis thev naus laus zis no tsom mus rau qhov hloov pauv tau yooj yim, kev ruaj khov, thiab kev hloov kho tshiab ntawm cov nroj tsuag uas twb muaj lawm, ua rau hydropower yog ib feem tseem ceeb ntawm kev hloov hluav taws xob huv.
Nrog rau lub ntiaj teb hydropower ntxiv muaj peev xwm nce mus txog 24.6 GW hauv 2024- suav nrog kev nce siab hauv cov twj tso kua mis-qhov kev lag luam no tau loj hlob kom tau raws li qhov xav tau hluav taws xob nce ntxiv thaum txhawb kev ruaj ntseg ntawm daim phiaj. Kev tsim kho tshiab hauv hydropower turbines, generators, thiab cov ntaub ntawv yog tsav cov kev hloov pauv no, tso cai rau cov nroj tsuag ua haujlwm kom ntseeg tau ntau dua hauv cov xwm txheej sib txawv.
Niaj hnub nimno turbines: Siv cov kev hloov pauv hloov tau zoo dua
Kev kho ib txwm muaj - ceev turbines ua haujlwm zoo ntawm kev thauj khoom tag nrho tab sis poob kev ua haujlwm thaum dej hloov pauv. Kev hloov pauv tshiab - ceev turbines kho lawv cov kev sib hloov ceev kom phim cov dej muaj, txhim kho kev ua haujlwm ntawm cov khoom thauj ib nrab thiab tso cai rau cov lus teb sai dua rau cov kev xav tau ntawm daim phiaj.
Cov tshuab no feem ntau siv cov kev tswj hwm qib siab xws li ob -fed induction generators. Cov tuam txhab xws li Voith Hydro thiab GE Vernova yog cov thawj coj nrog cov qauv tsim uas ua haujlwm tau zoo tshaj lub taub hau dav thiab ntws ntau. Qhov kev hloov pauv no yog qhov tseem ceeb rau cov kab sib chaws uas muaj kev sib koom siab ntawm kev sib txuas ntxiv dua tshiab.
Tsawg- lub taub hau thiab modular turbines tab tom qhib qhov chaw tshiab. Hydrokinetic turbines tsim hluav taws xob los ntawm cov dej ntws tsis muaj dams loj, thaum lub twj tso kua mis -raws li - turbines (PATs) muab cov nqi qis - kev xaiv rau cov haujlwm me.
Ntses-Tus phooj ywg Turbine Designs: Tiv Thaiv Dej Dej
Ib qho kev sib tw loj rau hydropower yog ntses hla turbines. Cov qauv tsim tshiab hais txog qhov no ncaj qha.
Natel Energy's Restoration Hydro Turbine (RHT) siv tuab, slanted hniav nrog cov npoo npoo. Kev ntsuas ywj pheej qhia tau tias 98-100% kev ciaj sia rau cov ntses xws li American eels, salmon, thiab sturgeon-ntau dua li 78% qhov nruab nrab rau cov pa turbines. Cov turbines no kuj haum rau cov dams uas twb muaj lawm, feem ntau tshem tawm qhov xav tau ntawm cov ntxaij vab tshaus ntses kim.
Lwm qhov kev tsim kho tshiab suav nrog yam tsawg kawg nkaus -gap runners thiab hydrokinetic designs uas txo cov kev pheej hmoo rau migrating hom. Cov ntses no-kev nyab xeeb hydropower turbines tso cai rau cov haujlwm kom ua tau raws li kev cai ib puag ncig nruj dua thaum tsim hluav taws xob
Kev txhim kho Generator rau Grid Support
Generators tau hloov zuj zus los muab ntau tshaj li qhov tso zis hluav taws xob xwb.
Cov hlau nplaum ruaj khov (PMGs) me dua thiab ua haujlwm tau zoo ntawm qhov nrawm, zoo tagnrho rau kev khiav - ntawm - dej los yog cov nroj tsuag me. Hloov pauv tau - cov tshuab hluav taws xob ceev, ua ke nrog cov thev naus laus zis xws li ob npaug -fed induction systems, muab kev tswj hwm zoo dua thiab cov kev pabcuam ntxiv xws li kev tswj hwm zaus.
Xyoo 2025, tej yaam num xws li Is Nrias teb lub Tehri twj tso kua mis cia cog commissioned lub teb chaws tus thawj variable - ceev units, txhim kho daim phiaj yooj.
Pumped Storage Hydropower: Loj hlob "Dej Roj Teeb"
Pumped storage hydropower (PSH) khaws lub zog los ntawm kev siv dej nce toj thaum xav tau qis thiab tso tawm kom tsim hluav taws xob thaum xav tau. Nws suav rau feem ntau daim phiaj thoob ntiaj teb- teev cia.
Hauv 2024, 8.4 GW ntawm PSH peev xwm tshiab tuaj hauv online, nqa tag nrho lub peev xwm mus rau 189 GW. Cov kav dej thoob ntiaj teb tam sim no tshaj 600 GW, nrog kev loj hlob muaj zog hauv Suav teb, Europe, thiab Africa.
Kev sib txawv - ceev PSH units txhim kho kev ua haujlwm hauv ob qho tib si siv thiab tsim hom. Hybrid systems sib txuas nrog PSH nrog roj teeb kuj tseem tshwm sim rau cov lus teb sai dua.
Advanced Materials thiab Digital Tools
Cov ntaub ntawv tshiab ua rau cov khoom siv sib dua thiab ntev dua -. Composites tuaj yeem txo qhov hnyav ntawm turbine los ntawm 50-80% thaum tiv thaiv corrosion thiab hnav. Superhydrophobic coatings txiav kev sib txhuam losses thiab tiv thaiv buildup.
Cov menyuam ntxaib digital, sensors, thiab AI ua kom muaj tseeb - lub sijhawm saib xyuas thiab kev saib xyuas kev kwv yees, txhawb kev tsim tawm thiab txo qis sijhawm. Cov hydropower kev nce qib hauv cov ntaub ntawv thiab digitalization txuas ntxiv cov nroj tsuag lub neej thiab cov nqi qis dua.
Raws li peb txav mus rau net-zero lub hom phiaj, cov kev txiav-ntug hydropower technologies ua kom cov sector tseem ntseeg tau, ua tau zoo, thiab lub luag haujlwm ntawm ib puag ncig. Los ntawm kev sib txawv ntawm -cov tshuab ceev mus rau ntses- qauv tsim, 2025 tau ua tiav kev nce qib hauv kev ua dej hauv lub hauv paus ntawm lub zog ruaj khov thoob ntiaj teb.
