Txhawm rau hloov lub zog siv hluav taws xob mus rau qhov hloov pauv tam sim no kom tau raws li tus qauv kab sib chaws, cov cua turbines yuav tsum tau nruab nrog lub zog hloov pauv, los ntawm qhov uas cov tshuab hluav taws xob muaj nyob rau hauv cov cua turbine nrog kev hloov ceev tau hloov mus rau qhov ruaj khov hloov tam sim no nyob rau hauv txoj kab nrog cov kab hluav taws xob thiab zaus tsis, peb hu no lub zog hloov dua siab tshiab lub zog tsim system.
Muaj ntau hom hluav taws xob tsim hluav taws xob rau niaj hnub loj cua turbines. Cov tuam txhab cua turbine sib txawv tau xaiv txoj kev sib txawv, thiab lawv tau tsim thiab tsim cov cua turbines nrog ntau hom kev tsim hluav taws xob, yog li peb tau pom cua turbines nrog cov duab sib txawv thiab sab hauv.
Raws li hom tsav tsheb, cua turbine hom tuaj yeem muab faib ua peb pawg: kev kub ceev tsav, nruab nrab ceev tsav thiab tsav ncaj qha, qhov chaw siab ceev tsav lub zog tsim hluav taws xob feem ntau suav nrog ob lub tshuab hluav taws xob asynchronous lub zog tsim hluav taws xob thiab squirrel tawb asynchronous zog. tiam systems, qauv peb hu ob-fed asynchronous generator teev thiab squirrel tawb asynchronous generator poob lawm; nruab nrab ceev tsav peb kuj hu ua semi-direct tsav, lub zog tsim tshuab rau cov hlau nplaum ruaj khov zog tsim tshuab, qauv peb hu ua semi-direct drive qauv. Lub tshuab hluav taws xob tsis tshua muaj hluav taws xob tsim hluav taws xob yog cov hlau nplaum ruaj khov generating system.
Txawm hais tias muaj ntau hom hluav taws xob tsim hluav taws xob, lawv cov kev teeb tsa tseem ceeb yog qhov zoo sib xws. Cov khoom tseem ceeb ntawm lub tshuab hluav taws xob tsim hluav taws xob yog cov tshuab hluav taws xob thiab cov hloov pauv. Raws li qhov sib txawv ntawm cov qauv ntawm cov tsav tsheb thiab qhov sib txawv ntawm cov tshuab hluav taws xob thiab cov hloov pauv, ntau lub tshuab hluav taws xob tsim hluav taws xob tau hloov zuj zus thiab tau ua tiav zoo rau cov cua turbines.
Ib qho ntawm cov khoom tseem ceeb ntawm lub tshuab hluav taws xob cua turbine yog lub tshuab hluav taws xob, uas hloov cov tshuab hluav taws xob rau hauv kev hloov tam sim no los ntawm lub tshuab hluav taws xob. Lub hom phiaj tseem ceeb ntawm cov tshuab hluav taws xob yog cov hlau nplaum ruaj khov synchronous generators, muab ob npaug rau asynchronous induction generators thiab squirrel tawb generators; ntau hom tshuab hluav taws xob sib txawv yog tsim rau ntau hom tsav saw hlau. Vim qhov tsis ruaj tsis khov ntawm cov cua, qhov zaus thiab qhov hluav taws xob ntawm qhov hloov pauv tam sim no los ntawm lub tshuab hluav taws xob tsis ruaj khov, yog li lub zog tsim hluav taws xob kuj yuav tsum tau nruab nrog lwm cov khoom tseem ceeb.
Lwm qhov tseem ceeb ntawm no yog lub converter. Cua turbines hloov qhov zaus thiab qhov hluav taws xob tsis ruaj tsis khov hluav taws xob los ntawm lub tshuab hluav taws xob mus rau hauv zaus thiab qhov hluav taws xob ruaj khov hluav taws xob uas ua tau raws li cov qauv kab sib chaws los ntawm lub converter, uas feem ntau muaj xws li tag nrho-fed converter thiab ob-fed converter. Lub tshuab hluav taws xob sib txawv yuav tsum tau teeb tsa nrog cov hloov pauv sib txawv kom ua tiav lub zog tsim hluav taws xob ruaj khov zoo, lub zog tsim hluav taws xob, tswj lub zog thiab lwm yam haujlwm.
Yog li, dab tsi yog lub ntsiab qauv teeb tsa ntawm kev lag luam cua fais fab rau lub tshuab tsim hluav taws xob? Cov hauv qab no yog cov lus qhia rau txhua tus ntawm lawv, muab rau koj saib macro ntawm hom hluav taws xob tsim hluav taws xob, lawv cov teeb tsa tseem ceeb thiab cov ntawv thov scenarios.
Doubly-fed asynchronous zog tsim tshuab
Doubly-fed asynchronous generators ntxiv rau doubly-fed converters
Lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob ob npaug ntawm lub tshuab hluav taws xob asynchronous cua turbine yog lub tshuab hluav taws xob ceev, thiab nws lub zog tsim hluav taws xob yog lub tshuab hluav taws xob sib txuas ua ke, uas muaj ob lub tshuab hluav taws xob asynchronous thiab lub tshuab hluav taws xob doubly-fed.
Lub impeller ntawm ob chav pub noj yog txuas nrog lub rotor ntawm lub tshuab hluav taws xob ob npaug ntawm asynchronous los ntawm kev ua kom nrawm nrawm. Qhov zaus, voltage, amplitude thiab theem ntawm lub rotor winding excitation tau hloov kho los ntawm lub converter raws li kev khiav hauj lwm yuav tsum tau, kom lub tsev yuav tsim hluav taws xob sib txawv speeds nrog ib tug tas li zaus, uas muaj qhov zoo ntawm ntau yam ceev. Kev tswj hwm, kev ywj pheej hloov ntawm lub zog ua haujlwm thiab rov ua haujlwm, lub peev xwm me me ntawm rotor excitation converter (kwv yees li 1/3 ntawm lub peev xwm ntsuas ntawm lub tshuab hluav taws xob), kev kub ceev, lub zog me me, qhov loj me thiab qhov hnyav, qhov loj ceev nce piv ntawm lub gearbox, Lub tshuab hluav taws xob nrog Slip rings thiab txhuam hniav cuam tshuam kev ntseeg tau rau qee yam. Tam sim no, ob chav pub khoom noj yog cov cua turbines tshaj plaws.
Squirrel tawb asynchronous power generation systems
Squirrel tawb asynchronous generators ntxiv rau tag nrho lub hwj chim converters
Piv nrog rau ob-fed asynchronous cua turbines, qhov sib txawv tseem ceeb ntawm squirrel-cage asynchronous cua turbine zog tsim tshuab yog tias lub tshuab hluav taws xob rotor yog lub kaw lub tawb kaw, uas tsis tas yuav tsum muaj cov qauv xws li txhuam thiab cov hlua khi, thiab lub tshuab hluav taws xob stator windings. yog networked ntawm ib tug tag nrho-power converter.
