Hydroelectric generator teeb yog lub zog hloov khoom siv uas hloov lub zog ntawm cov dej mus rau hauv hluav taws xob. Nws feem ntau yog tsim los ntawm dej turbine, lub tshuab hluav taws xob, tus tswv xeev, excitation system, cua txias system thiab cov khoom siv hluav taws xob tswj chaw nres tsheb.
(1) Hydraulic turbine: muaj ob hom hydraulic turbines nquag siv: impulse hom thiab hom tshuaj tiv thaiv.
(2) Lub tshuab hluav taws xob: feem ntau cov tshuab hluav taws xob yog cov tshuab hluav taws xob synchronous, nrog kev ceev qis, feem ntau qis dua 750r / min, thiab qee qhov tsuas muaj kaum tawm ntawm kev hloov pauv / feeb; Vim tias qhov ceev ceev, muaj ntau cov hlau nplaum sib nqus; Cov qauv loj loj thiab qhov hnyav; Muaj ob hom kev teeb tsa ntawm hydraulic generator units: ntsug thiab kab rov tav.
(3) Kev tswj ceev ceev thiab tswj cov cuab yeej (xws li tus tswv xeev ceev thiab cov cuab yeej siv roj): lub luag haujlwm ntawm tus tswv xeev ceev yog tswj xyuas qhov ceev ntawm lub tshuab hluav taws xob hydraulic, txhawm rau xyuas kom meej tias qhov zaus ntawm cov khoom siv hluav taws xob ua tau raws li qhov yuav tsum tau ua ntawm lub hwj chim, thiab ua kom tiav chav ua haujlwm (pib, kaw, hloov ceev, load nce thiab load txo) thiab kev nyab xeeb thiab kev lag luam. Yog li ntawd, kev ua haujlwm ntawm tus tswv xeev yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm sai, cov lus teb rhiab heev, kev ruaj ntseg sai, kev ua haujlwm yooj yim thiab kev saib xyuas, thiab nws tseem yuav tsum muaj kev lag luam txhim khu kev qha thiab kev kaw thaum muaj xwm txheej ceev.
(4) Excitation system: hydraulic generator feem ntau yog electromagnetic synchronous generator. Los ntawm kev tswj hwm ntawm DC excitation system, kev tswj hluav taws xob hluav taws xob hluav taws xob, kev tswj hwm lub zog thiab lub zog reactive thiab lwm yam kev tswj hwm tuaj yeem ua tiav los txhim kho qhov zoo ntawm cov zis hluav taws xob.
(5) Lub tshuab cua txias: cua txias feem ntau yog siv rau lub tshuab hluav taws xob me me kom txias lub stator, rotor thiab hlau core nto ntawm lub tshuab hluav taws xob nrog qhov cua. Txawm li cas los xij, nrog kev nce ntawm ib chav tsev muaj peev xwm, thermal loads ntawm stator thiab rotor yog tas li nce. Txhawm rau ua kom lub zog tso zis ntau ntxiv rau ib chav tsev ntim ntawm lub tshuab hluav taws xob ntawm qee qhov ceev, lub peev xwm loj hydraulic generator txais cov dej txias ncaj qha ntawm stator thiab rotor windings; Los yog lub stator winding yog txias los ntawm dej, thaum lub rotor txias los ntawm cua muaj zog.
(6) Cov khoom siv hluav taws xob tswj chaw nres tsheb: cov khoom siv hluav taws xob hauv chaw tswj hwm yog microcomputer feem ntau, uas paub txog kev ua haujlwm ntawm kev sib txuas ntawm kab sib txuas, kev tswj hluav taws xob, kev hloov pauv zaus, kev tswj hwm lub zog, kev tiv thaiv thiab kev sib txuas lus ntawm cov tshuab hluav taws xob hydraulic.
(7) Braking ntaus ntawv: tag nrho cov tshuab hluav taws xob hydraulic uas muaj peev xwm tshaj li qhov muaj peev xwm tau nruab nrog cov cuab yeej siv braking, uas yog siv los txuas ntxiv nres lub rotor thaum qhov ceev raug txo mus rau 30% ~ 40% ntawm qhov ntsuas ceev thaum lub tshuab hluav taws xob kaw, txhawm rau tiv thaiv qhov kev cuam tshuam ntawm kev kub hnyiab vim roj zaj duab xis puas ntawm qhov ceev. Lwm txoj haujlwm ntawm cov cuab yeej braking yog txhawm rau txhawm rau tig qhov chaw ntawm lub tshuab hluav taws xob nrog cov roj siab ua ntej kev teeb tsa, kev saib xyuas thiab pib. Cov khoom siv braking siv compressed cua rau braking
