Kev tsim hluav taws xob hauv hluav taws xob, raws li kev rov ua dua tshiab, tsis muaj kuab lom thiab huv lub zog, tau ntev los ntawm tib neeg. Niaj hnub no, cov chaw nres tsheb loj thiab nruab nrab cov chaw siv dej tau siv dav thiab cov thev naus laus zis thev naus laus zis thev naus laus zis thoob ntiaj teb. Piv txwv li, Peb Gorges hydropower chaw nres tsheb hauv Suav teb yog qhov chaw nres tsheb loj tshaj plaws hauv ntiaj teb. Txawm li cas los xij, cov chaw nres tsheb loj thiab nruab nrab muaj ntau qhov cuam tshuam tsis zoo rau ib puag ncig, xws li cov kwj dej thaiv cov dej ntws zoo ntawm cov dej ntws, thaiv cov dej ntws tawm, thiab hloov cov ecosystem ib puag ncig; Kev tsim kho ntawm cov chaw nres tsheb hauv dej kuj tseem yuav tsum tau muaj dej ntws los ntawm thaj av, ua rau muaj coob tus neeg tuaj txawv teb chaws.
Raws li lub zog tshiab, lub zog me me muaj qhov cuam tshuam me me rau ntawm ib puag ncig ecological, thiab yog li ntawd tau nce nqi los ntawm tib neeg. Cov chaw nres tsheb me me, zoo li cov chaw nres tsheb loj thiab nruab nrab, yog ob qho tib si hydroelectric fais fab nroj tsuag. Cov feem ntau hu ua "me me hydropower" yog hais txog hydropower chaw nres tsheb lossis hydroelectric fais fab nroj tsuag thiab cov tshuab hluav taws xob nrog lub peev xwm me me, thiab lawv lub peev xwm nruab tau txawv nyob ntawm lub teb chaws ntawm txhua lub teb chaws.
Hauv Suav teb, "me me hydropower" yog hais txog cov chaw nres tsheb hauv dej thiab txhawb cov phiaj xwm hauv zos nrog lub peev xwm ntawm 25MW lossis tsawg dua, uas tau txais nyiaj txiag thiab ua haujlwm los ntawm cov chaw hauv zos, pawg, lossis ib tus neeg. Me me hydropower belongs rau cov uas tsis yog carbon huv zog, uas tsis muaj teeb meem ntawm kev pab cuam depletion thiab tsis ua paug rau ib puag ncig. Nws yog ib qho tseem ceeb ntawm Tuam Tshoj txoj kev siv lub tswv yim txhim kho kom ruaj khov.
Kev tsim lub zog tauj dua tshiab xws li cov dej me me raws li cov xwm txheej hauv zos thiab hloov pauv cov peev txheej hauv cov hluav taws xob zoo tau ua lub luag haujlwm tseem ceeb hauv kev ua kom lub teb chaws kev lag luam thiab kev loj hlob ntawm tib neeg, txhim kho lub neej zoo ntawm cov neeg, daws cov teeb meem ntawm kev siv hluav taws xob hauv cheeb tsam uas tsis muaj hluav taws xob thiab hluav taws xob tsis txaus, txhawb kev tswj hwm dej, kev txhim kho ecological, kev tiv thaiv ib puag ncig, thiab kev loj hlob hauv zej zog.
Tuam Tshoj muaj ntau reserves ntawm me me hydropower peev, nrog rau theoretical kwv yees cia ntawm 150 lab kW thiab muaj peev xwm ntsia tau tshaj 70000 MW rau txoj kev loj hlob. Nws yog ib qho kev xaiv uas yuav tsum tau ua kom muaj zog tsim cov dej me me los txhim kho cov qauv siv hluav taws xob hauv cov ntsiab lus ntawm kev tiv thaiv ib puag ncig qis, kev txuag hluav taws xob thiab txo qis emissions, thiab kev txhim kho kom ruaj khov. Raws li txoj kev npaj ntawm Ministry of Water Resources, los ntawm 2020, Tuam Tshoj yuav tsim 10 lub xeev me me hydropower nrog ib tug muaj peev xwm ntawm ntau tshaj 5 lab kW, 100 loj me me hydropower bases nrog ib tug nruab muaj peev xwm ntawm ntau tshaj 200000 kW, thiab 300 me me hydropower counties nrog ib tug ntsia muaj peev xwm ntawm tshaj 100000 kW. Txog xyoo 2023, raws li Ministry of Water Resources tau npaj tseg, kev tsim hluav taws xob me me yuav tsis tsuas yog ua tiav lub hom phiaj xyoo 2020, tab sis kuj tseem muaj kev txhim kho ntau dua ntawm lub hauv paus no.
Lub tshuab hluav taws xob hluav taws xob yog lub tshuab hluav taws xob tsim hluav taws xob uas hloov dej zog rau hauv hluav taws xob los ntawm lub tshuab hluav taws xob dej, thiab lub tshuab hluav taws xob dej turbine yog cov cuab yeej tseem ceeb rau kev ua tiav lub zog hloov hauv cov tshuab hluav taws xob me me. Cov txheej txheem hloov hluav taws xob ntawm lub tshuab hluav taws xob hluav taws xob tau muab faib ua ob theem.
Thawj theem hloov lub peev xwm ntawm cov dej mus rau hauv lub tshuab hluav taws xob ntawm cov dej turbine. Cov dej ntws muaj lub zog sib txawv ntawm qhov siab thiab qhov chaw sib txawv. Thaum cov dej ntws los ntawm qhov chaw siab dua cuam tshuam rau lub turbine ntawm qhov chaw qis, lub zog muaj peev xwm tsim los ntawm cov dej hloov pauv hloov mus rau hauv lub zog ntawm lub turbine.
Nyob rau theem ob, lub zog txhua yam ntawm cov dej turbine yog thawj zaug hloov mus rau hauv hluav taws xob hluav taws xob, uas yog tom qab ntawd xa mus rau cov khoom siv hluav taws xob los ntawm cov kab sib txuas ntawm daim phiaj hluav taws xob. Tom qab raug cuam tshuam los ntawm cov dej ntws, cov dej turbine tsav lub coaxial txuas lub tshuab hluav taws xob tig. Lub tshuab hluav taws xob rotating rotor tsav lub excitation magnetic teb kom tig, thiab lub stator winding ntawm lub tshuab hluav taws xob txiav cov excitation magnetic teb kab los tsim induced electromotive quab yuam. Ntawm ib sab, nws outputs hluav taws xob lub zog, thiab ntawm qhov tod tes, nws generates electromagnetic braking torque nyob rau hauv lub opposite kev taw qhia ntawm kev sib hloov ntawm lub rotor. Cov dej ntws tsis tu ncua cuam tshuam rau cov khoom siv dej turbine, thiab cov rotational torque tau los ntawm cov dej turbine los ntawm cov dej ntws overcomes lub electromagnetic braking torque generated nyob rau hauv lub generator rotor. Thaum ob qho tib si ncav cuag qhov sib npaug, chav dej turbine yuav ua haujlwm ntawm qhov nrawm kom ruaj khov tsim hluav taws xob thiab ua tiav lub zog hloov pauv.
Lub tshuab hluav taws xob hydroelectric teeb yog ib qho tseem ceeb ntawm lub zog hloov hluav taws xob uas hloov lub peev xwm ntawm dej mus rau hauv hluav taws xob hluav taws xob. Nws feem ntau muaj lub tshuab hluav taws xob dej, lub tshuab hluav taws xob, lub tshuab hluav taws xob ceev, lub zog excitation, cua txias system, thiab cov cuab yeej tswj fais fab. Kev taw qhia luv luv rau cov hom thiab kev ua haujlwm ntawm cov cuab yeej tseem ceeb hauv cov txheej txheem hydroelectric generator yog raws li hauv qab no:
1) Dej turbine. Muaj ob hom kev siv dej turbines: impulse thiab reactive.
2) Lub tshuab hluav taws xob. Feem ntau cov tshuab hluav taws xob siv hluav taws xob zoo siab synchronous generators.
3) Excitation system. Vim qhov tseeb tias cov tshuab hluav taws xob feem ntau yog cov hluav taws xob zoo siab synchronous generators, nws yog ib qho tsim nyog los tswj cov DC excitation system kom ua tiav cov kev cai voltage, nquag thiab reactive zog tswj ntawm hluav taws xob lub zog, thiaj li yuav txhim kho qhov zoo ntawm cov zis hluav taws xob zog.
4) Kev tswj ceev thiab tswj cov cuab yeej (nrog rau kev tswj ceev thiab cov cuab yeej roj siab). Tus tswv xeev yog siv los tswj qhov ceev ntawm cov dej turbine, kom qhov zaus ntawm cov zis hluav taws xob ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob.
5) Cua txias system. Cov tshuab hluav taws xob me me feem ntau siv cua txias, siv lub tshuab ua pa los pab kom cov cua sov thiab txias ntawm lub tshuab hluav taws xob lub tshuab hluav taws xob stator, rotor, thiab cov tub ntxhais hlau.
6) Braking ntaus ntawv. Hydraulic generators uas muaj peev xwm tshaj li ib qho nqi yog nruab nrog cov khoom siv braking.
7) Fais fab nroj tsuag tswj cov cuab yeej. Cov cuab yeej siv hluav taws xob feem ntau siv lub tshuab hluav taws xob digital tswj kom ua tiav cov haujlwm xws li kev sib txuas ntawm kab sib chaws, kev tswj hwm zaus, kev tswj hluav taws xob, kev tswj hwm hluav taws xob, kev tiv thaiv, thiab kev sib txuas lus ntawm lub zog hluav taws xob.
Lub tshuab hluav taws xob me me tuaj yeem muab faib ua hom kev hloov pauv, hom twj tso kua mis, thiab hom hybrid raws li txoj kev ntawm lub taub hau concentrated. Feem ntau cov chaw siv hluav taws xob me me hauv Suav teb yog cov kev lag luam sib txawv ntawm cov chaw siv hluav taws xob me me.
Cov yam ntxwv ntawm lub tshuab hluav taws xob me me yog qhov chaw nres tsheb me me, kev tsim vaj tsev yooj yim, kev yuav khoom yooj yim, thiab siv tus kheej, tsis muaj hluav taws xob xa mus rau qhov chaw nyob deb ntawm qhov chaw nres tsheb; Daim phiaj hluav taws xob me me muaj peev xwm me me, thiab lub peev xwm tsim hluav taws xob kuj tseem me me. Kev tsis lees txais cov hluav taws xob me me muaj zog hauv zos thiab cov yam ntxwv loj.
Raws li lub zog huv si, me me hydropower tau pab txhawb kev tsim kho cov zej zog tshiab zog hauv Suav teb. Peb ntseeg hais tias kev sib xyaw ntawm me me hydropower thiab lub zog cia technology yuav ua rau kev loj hlob ntawm me me hydropower ntau eye-catching nyob rau hauv lub neej yav tom ntej!
