Cov chaw tsim hluav taws xob axial-flow, feem ntau nruab nrog Kaplan turbines, zoo tagnrho rau cov chaw uas muaj qhov dej ntws qis mus rau nruab nrab thiab cov dej ntws loj. Cov turbines no siv dav hauv cov dej ntws thiab cov dej ntws qis vim lawv ua haujlwm tau zoo thiab hloov tau yooj yim. Kev vam meej ntawm cov chaw tsim hluav taws xob hydropower no vam khom rau kev tsim qauv zoo thiab ua tib zoo ua haujlwm, uas tsim lub hauv paus rau kev ua haujlwm ntawm turbine, kev ruaj khov ua haujlwm, thiab kev nyab xeeb.
1. Kev Npaj Qhov Chaw thiab Kev Hloov Tus Dej
Ua ntej yuav pib ua kev tsim kho loj, kev npaj qhov chaw yog qhov tseem ceeb heev. Qhov no suav nrog kev tshem tawm thaj chaw tsim kho, teeb tsa txoj kev nkag, thiab tsim kom muaj lub kaw lus hloov dej kom hloov txoj kev thiab tsim kom muaj ib puag ncig ua haujlwm qhuav. Cofferdams—cov chaw kaw ib ntus uas ua hauv lossis hla tus dej—feem ntau yog siv los cais qhov chaw tsim kho ntawm dej.
2. Cov Qauv Txais Tos
Cov qauv dej nkag tswj cov dej nkag mus rau hauv lub chaw tsim hluav taws xob thiab xyuas kom tsis muaj khib nyiab, dej ntws ruaj khov mus rau lub turbine. Nws suav nrog cov khib nyiab, rooj vag, thiab qee zaum cov chaw ntxuav cov av qias neeg. Kev tsim hydraulic kom zoo yog qhov tseem ceeb los tiv thaiv kev tsim vortex, txo qhov poob ntawm lub taub hau, thiab tiv thaiv lub turbine ntawm cov khib nyiab ntab.
3. Penstock los yog Qhib Channel
Nyob ntawm seb qhov layout zoo li cas, cov dej los ntawm qhov intake yuav raug xa mus rau lub turbine los ntawm cov penstocks (cov kav dej kaw) lossis cov channel qhib. Hauv ntau qhov axial-flow designs—tshwj xeeb tshaj yog nyob rau hauv cov nroj tsuag qis--ib qho qhib intake txuas ncaj qha rau lub turbine yog siv. Kev ruaj khov ntawm cov qauv, kev ntws sib npaug, thiab kev txo qis ntawm kev poob hydraulic yog qhov kev txhawj xeeb tseem ceeb thaum lub sijhawm no.
4. Lub Tsev Fais Fab
Lub chaw ua hluav taws xob muaj cov chav turbine-generator, cov txheej txheem tswj, thiab cov khoom siv pabcuam. Rau Kaplan turbines, uas feem ntau yog ntsia ntsug, lub chaw ua hluav taws xob yuav tsum tau tsim los txhawb cov khoom thauj loj axial thiab cov zog dynamic. Kev ruaj khov ntawm kev co, kev tiv thaiv dej, thiab kev yooj yim nkag mus rau kev saib xyuas yog cov yam tseem ceeb ntawm kev tsim qauv.
5. Lub raj xa dej thiab kev sib tw khiav tsheb
Lub raj xa dej ua lub luag haujlwm tseem ceeb hauv kev rov qab tau lub zog kinetic ntawm cov dej uas tawm hauv lub turbine. Lub raj xa dej uas tsim tau zoo ua rau muaj kev ua haujlwm zoo dua. Lub qhov dej tom qab xa dej rov qab mus rau tus dej kom muaj kev nyab xeeb. Ob qho tib si yuav tsum tau ua kom raug kom txo tau qhov cua daj cua dub thiab cov dej ntws rov qab.
6. Chav Tswj thiab Cov Tsev Pabcuam
Sib nrug ntawm cov qauv tseem ceeb, cov haujlwm pej xeem kuj suav nrog kev tsim cov chav tswj hwm, chaw nyob rau cov neeg ua haujlwm, cov chaw ua haujlwm, thiab lwm lub tsev ua haujlwm. Cov chaw no ua kom ntseeg tau tias lub Hoobkas ua haujlwm tau zoo thiab kev saib xyuas mus sij hawm ntev.
7. Kev Xav Txog Ib Puag Ncig thiab Geotechnical
Kev tshawb nrhiav av, kev ruaj khov ntawm qhov av, kev tswj kev yaig av, thiab kev tiv thaiv ib puag ncig yog cov feem tseem ceeb ntawm kev npaj pej xeem. Cov txheej txheem ntws dej kom zoo, txoj kev nuv ntses (yog tias xav tau), thiab kev ua haujlwm kho kom zoo nkauj pab txo qhov cuam tshuam rau ib puag ncig ntawm qhov project.
Lub hauv paus tseem ceeb ntawm kev tsim kho vaj tse ntawm lub chaw tsim hluav taws xob axial-flow yog qhov tseem ceeb rau nws txoj kev ua haujlwm thiab lub neej ntev. Txhua lub qauv - los ntawm qhov nkag mus rau qhov kawg - yuav tsum tau tsim thiab ua tib zoo kom tiv taus cov zog hydrological, cov xwm txheej geological, thiab kev xav tau kev ua haujlwm. Kev koom tes ze ntawm cov kws ua haujlwm pej xeem, cov neeg muab khoom siv hydropower, thiab cov kws tshaj lij ib puag ncig yog qhov tseem ceeb rau kev xa cov kev daws teeb meem hydropower nyab xeeb, ua haujlwm tau zoo, thiab ruaj khov.
