Keeb kwm thiab cov yam ntxwv ntawm kev huv, rov ua dua tshiab hydroelectric zog

Hydropower yog ib lub tshuab hluav taws xob tauj dua tshiab uas siv lub zog kinetic ntawm dej los tsim hluav taws xob. Nws yog siv dav siv lub zog huv nrog ntau qhov zoo, xws li kev rov ua dua tshiab, tsis muaj emissions, stability thiab controllability. Lub hauv paus ntsiab lus ua haujlwm ntawm hydropower yog raws li lub tswv yim yooj yim: siv lub zog kinetic ntawm cov dej ntws los tsav lub turbine, uas tig lub tshuab hluav taws xob los tsim hluav taws xob. Cov kauj ruam ntawm kev tsim hluav taws xob tsim hluav taws xob yog: kev hloov dej los ntawm ib lub reservoir los yog tus dej, uas yuav tsum tau muaj dej, feem ntau yog ib lub reservoir (cov khoom siv hluav taws xob) los yog ib tug dej ntuj, uas muab lub hwj chim; Kev taw qhia dej ntws, qhov twg cov dej ntws tau coj mus rau cov hniav ntawm lub turbine los ntawm kev hloov pauv channel. Kev hloov pauv channel tuaj yeem tswj cov dej ntws ntws los kho lub zog tsim hluav taws xob; lub turbine khiav, thiab cov dej ntws hits cov hniav ntawm lub turbine, ua rau nws tig. Lub turbine zoo ib yam li lub log cua hauv cua tshuab tsim; lub tshuab hluav taws xob tsim hluav taws xob, thiab kev ua haujlwm ntawm lub turbine tig lub tshuab hluav taws xob, uas tsim hluav taws xob los ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction; lub zog xa hluav taws xob, lub zog tsim hluav taws xob tau xa mus rau hauv daim phiaj hluav taws xob thiab xa mus rau cov nroog, kev lag luam thiab tsev neeg. Muaj ntau hom hydropower. Raws li cov qauv kev ua haujlwm sib txawv thiab cov txheej txheem kev thov, nws tuaj yeem muab faib ua cov dej hluav taws xob tsim hluav taws xob, tsim hluav taws xob reservoir, tidal thiab dej hiav txwv fais fab, thiab me me hydropower. Hydropower muaj ntau yam zoo, tab sis kuj muaj qee qhov tsis zoo. Qhov zoo yog qhov tseem ceeb: hydropower yog lub zog tauj dua tshiab. Hydropower tso siab rau cov dej ntws, yog li nws tuaj yeem rov ua dua tshiab thiab yuav tsis tag; nws yog lub zog huv si. Hydropower tsis tsim cov pa roj carbon monoxide thiab cov pa phem, thiab tsis muaj kev cuam tshuam rau ib puag ncig; nws yog tswj tau. Hydropower chaw nres tsheb tuaj yeem hloov kho raws li qhov xav tau los muab kev ntseeg tau yooj yim load zog. Qhov tsis zoo tseem ceeb yog: cov dej num loj loj tuaj yeem ua rau muaj kev puas tsuaj rau cov ecosystem, nrog rau cov teeb meem hauv zej zog xws li kev tsiv teb tsaws chaw nyob thiab av expropriation; hydropower yog txwv los ntawm kev muaj peev xwm ntawm cov dej, thiab kev qaug zog los yog dej ntws poob yuav cuam tshuam rau kev tsim hluav taws xob.
Hydropower, raws li daim ntawv txuas ntxiv ntawm lub zog, muaj keeb kwm ntev. Cov dej turbines thaum ntxov thiab lub log dej: Thaum ntxov li 2 xyoo pua BC, tib neeg pib siv cov dej turbines thiab cov log dej los tsav cov tshuab xws li zeb thiab sawmills. Cov tshuab no siv lub zog kinetic ntawm cov dej ntws los ua haujlwm. Kev tshwm sim ntawm lub zog tsim hluav taws xob: Nyob rau hauv lub xyoo pua puv 19, tib neeg tau pib siv lub tshuab hluav taws xob hluav taws xob los hloov dej zog rau hauv hluav taws xob. Lub ntiaj teb thawj lub chaw tsim hluav taws xob ua lag luam tau tsim nyob rau hauv Wisconsin, Tebchaws Asmeskas hauv xyoo 1882. Kev tsim cov dams thiab reservoirs: Nyob rau hauv lub xyoo pua 20th, qhov ntsuas ntawm hydropower nthuav dav heev nrog kev tsim cov dams thiab reservoirs. Cov dej num nto moo muaj xws li Hoover Dam hauv Tebchaws Meskas thiab Peb Lub Gorges Dam hauv Suav teb. Kev siv thev naus laus zis: Sijhawm dhau los, kev siv thev naus laus zis thev naus laus zis tau txhim kho tas li, suav nrog kev qhia txog turbines, hydro-generators thiab ntse tswj tshuab, uas tau txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm hydropower.
Hydropower yog lub zog huv, rov ua dua tshiab, thiab nws cov saw hlau kev lag luam npog ntau qhov txuas tseem ceeb, los ntawm kev tswj hwm dej mus rau kev xa hluav taws xob. Thawj qhov txuas hauv kev lag luam hydropower yog kev tswj hwm dej. Qhov no suav nrog kev teem sijhawm, khaws cia thiab faib cov dej ntws kom ntseeg tau tias cov dej tuaj yeem ruaj khov rau cov turbines rau kev tsim hluav taws xob. Kev tswj xyuas cov peev txheej dej feem ntau yuav tsum tau saib xyuas qhov ntsuas xws li dej nag, dej ntws nrawm thiab qib dej txhawm rau txiav txim siab tsim nyog. Kev tswj hwm dej niaj hnub no tseem tsom mus rau kev ruaj khov kom ntseeg tau tias lub zog tsim hluav taws xob tuaj yeem tswj tau txawm tias nyob rau hauv qhov xwm txheej hnyav xws li dej qhuav. Dams thiab reservoirs yog cov chaw tseem ceeb hauv kev lag luam hydropower. Cov dams feem ntau yog siv los nce qib dej thiab tsim cov dej siab, yog li ua kom lub zog kinetic ntawm cov dej ntws. Reservoirs yog siv los khaws cov dej kom ntseeg tau tias cov dej txaus txaus tuaj yeem muab tau thaum lub sijhawm xav tau. Kev tsim thiab kev tsim cov dams yuav tsum xav txog geological tej yam kev mob, dej ntws yam ntxwv thiab ecological cuam tshuam los xyuas kom meej kev ruaj ntseg thiab sustainability. Turbines yog cov khoom tseem ceeb hauv kev lag luam hydropower chain. Thaum cov dej ntws los ntawm cov hniav ntawm lub turbine, nws lub zog kinetic hloov mus rau txhua yam zog, uas ua rau lub turbine tig. Cov qauv tsim thiab hom turbine tuaj yeem xaiv raws li cov dej ntws nrawm, tus nqi ntws thiab qhov siab kom ua tiav lub zog siab tshaj plaws. Thaum lub turbine tig, nws tsav lub tshuab hluav taws xob txuas los tsim hluav taws xob. Lub tshuab hluav taws xob yog cov cuab yeej tseem ceeb uas hloov cov tshuab hluav taws xob rau hauv hluav taws xob hluav taws xob. Feem ntau, lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm lub tshuab hluav taws xob yog induce tam sim no los ntawm ib tug rotating magnetic teb los tsim alternating tam sim no. Tus tsim thiab muaj peev xwm ntawm lub tshuab hluav taws xob yuav tsum tau txiav txim siab raws li qhov xav tau ntawm lub zog thiab cov yam ntxwv ntawm cov dej ntws. Lub zog hluav taws xob tsim los ntawm lub tshuab hluav taws xob yog hloov tam sim no, uas feem ntau yuav tsum tau ua tiav los ntawm lub substation. Lub luag haujlwm tseem ceeb ntawm lub chaw nres tsheb muaj xws li kev nce qib (nce qhov hluav taws xob kom txo qis zog thaum lub zog xa mus) thiab hloov hom tam sim no (hloov AC rau DC lossis rov ua dua) kom tau raws li qhov yuav tsum tau muaj ntawm lub zog xa hluav taws xob. Qhov txuas kawg yog kev xa hluav taws xob. Lub zog hluav taws xob tsim los ntawm lub chaw nres tsheb fais fab kis tau mus rau cov neeg siv hluav taws xob hauv nroog, kev lag luam lossis nyob deb nroog los ntawm cov kab sib kis. Cov kab sib kis yuav tsum tau npaj, tsim thiab tswj xyuas kom ntseeg tau tias lub zog xa mus rau qhov chaw nyab xeeb thiab ua haujlwm tau zoo. Hauv qee qhov chaw, lub zog kuj tseem yuav tsum tau ua dua los ntawm lub chaw nres tsheb kom ua tau raws li qhov yuav tsum tau muaj ntawm qhov sib txawv voltages thiab zaus.
