Txhua lub tshuab hluav taws xob tsim nyob ib puag ncig lub tshuab hluav taws xob teeb lossis kab hluav taws xob-tied inverters ntsib qhov teeb meem tseem ceeb hauv kev zais uas hu ua lub zog rov qab. Txawm hais tias qhov teeb meem no ua rau muaj kev ceeb toom me ntsis thaum xub thawj siab ib muag, nws ua rau muaj kev puas tsuaj loj heev.
Yooj yim txhais, rov qab fais fab tshwm sim thaum hluav taws xob ntws rov qab los ntawm koj lub zog hluav taws xob. Ib qho xwm txheej tshwm sim: lub tshuab hluav taws xob tsim kom xa hluav taws xob tawm mus rau daim phiaj tam sim ntawd rub lub zog tawm ntawm daim phiaj, khiav zoo li lub tshuab hluav taws xob hloov. Lwm qhov tshwm sim thaum lub teeb hluav taws xob hluav taws xob: hnub ci lossis roj teeb cia inverters tsis raug kaw thiab ua kom thawb lub zog rov qab mus rau hauv cov khoom siv hluav taws xob. Qhov kev hloov hluav taws xob thim rov qab no ua rau tsis muaj kev ceeb toom ua ntej, thiab tuaj yeem ua rau rov qab tsis tau, lub neej - hem kev puas tsuaj hauv vib nas this xwb - suav nrog cov qhab nia hnyav ntawm lub tshuab hluav taws xob prime mover lub tog raj kheej, kev puas tsuaj loj thiab tawg ntawm inverter fais fab modules, lossis hluav taws xob tag nrho.
Txhawm rau rhuav tshem cov neeg kho tshuab thiab hluav taws xob puas tsuaj, pib nrog cov tshuab hluav taws xob synchronous khiav nyob rau hauv tib lub sij hawm nrog rau daim phiaj siv hluav taws xob. Yog hais tias cov khoom siv roj txiav tawm los yog tus tswv xeev system ua haujlwm tsis zoo, tus thawj txav mus los poob cov zis torque. Daim phiaj ces rub lub tshuab hluav taws xob nrog rau ntawm synchronous ceev tiv thaiv nws lub hom phiaj ua haujlwm.
Thaum lub cav diesel tau spun passively li no, ib txwm combustion siab thiab tiv thaiv lubricating roj zaj duab xis ploj. Kev sib txhuam ntawm cov piston, lub tog raj kheej liner thiab cov hlua txuas txuas nrawm nrawm, ua kom muaj cua sov ntau dhau. Tsis pub dhau lub vib nas this, qhov no ua rau lub tog raj kheej phab ntsa cov qhab nia, xauv cov bearings, lossis ua tiav cov pas nrig txuas tsis ua haujlwm.
Rau kev teeb tsa hnub ci PV, daim phiaj hluav taws xob poob yuav tsum ua rau lub inverter kaw tam sim. Yog hais tias chav tsev ua haujlwm tsis zoo, nws tsis nyeem cov kab sib txuas uas tsis yog qhov chaw nyob thiab ua haujlwm tawm ntawm nws qhov kev siv hluav taws xob sab hauv, tsim kom muaj qhov txaus ntshai ntawm lub zog hluav taws xob. Thaum cov neeg ua haujlwm siv hluav taws xob lossis cov khoom siv tsis siv neeg rov- kaw daim phiaj tawg tom qab, qhov tsis sib xws ntawm qhov hluav taws xob tsis sib haum thiab qhov amplitude ntawm cov kab hluav taws xob sib cais thiab daim phiaj tseem ceeb tsim kom muaj kev cuam tshuam loj heev tam sim no. Qhov no tam sim ntawd hlawv tawm lub inverter lub DC tsheb npav capacitors thiab IGBT fais fab hloov, tawm hauv melted, charred hardware nyob rau hauv lub txee tswj.
Kev tiv thaiv rov qab fais fab: Automated ceev-Kev Tiv Thaiv Kev Nyab Xeeb
Kev tiv thaiv hluav taws xob rov qab ua haujlwm tam sim, tsis siv neeg tiv thaiv kev nyab xeeb kom nres cov kev ua tsis tiav ua ntej lawv nce. Nws cov khoom siv tseem ceeb yog qhov siab - qhov tseeb lub zog kev taw qhia ntsuas qhov ntsuas tau nyob hauv lub zog zoo saib lossis tiv thaiv relays.
Qhov no sensor txuas ntxiv mus kuaj tiag tiag -lub sij hawm voltage thiab tam sim no waveforms, xam ob qho tib si lub ntim thiab taw qhia ntawm lub active zog khiav. Lub kaw lus ua rau muaj kev ceeb toom rov qab fais fab tuag thaum ob qho xwm txheej tau ntsib:
1.Rov qab lub zog muaj zog tshaj tus neeg siv -kho qhov pib, ib txwm teeb tsa nruab nrab ntawm 5% thiab 15% ntawm chav tsev ntsuas rau pem hauv ntej lub zog tso zis;
2.Qhov rov qab ntws mus rau yav dhau los lub sijhawm luv luv lub sijhawm ncua sijhawm (ntau mus rau pua pua milliseconds), ua rau kom tshem tawm cov kev ua txhaum cai tsis raug cai los ntawm lub zog hloov pauv.
Thaum lees paub qhov kev tshwm sim muaj zog rov qab siv tau, cov khoom siv sab hauv- lub xeev relays lossis cov neeg kho tshuab qhuav xa cov teeb liab tam sim ntawd los qhib daim phiaj khi Circuit Court breaker. Qhov no txiav cov kab sib txuas ceev txaus kom nres cov neeg kho tshuab inertia thiab kub tsim ua ntej kev puas tsuaj mus tas li.
Tiag -Kev tiv thaiv kev puas tsuaj hauv ntiaj teb hla txhua lub cuab tam muaj zog
Qhov kev tiv thaiv kev tiv thaiv no tshem tawm ntau hom kev puas tsuaj loj thoob plaws ntau hom khoom siv hluav taws xob:
Lub tshuab hluav taws xob teeb: Tripping lub breaker cais lub tshuab hluav taws xob los ntawm kab sib chaws, halting passive yuam kev sib hloov ntawm prime mover. Qhov no nres cascading mechanical hnav thaum tsis txhob winding overheating, dhau tam sim no kos thiab tag nrho voltage vau los ntawm kev txhawb zog rov qab.
Hnub ci & roj teeb cia inverters: Kev tiv thaiv hluav taws xob rov qab ua ke ncaj qha nrog kev tiv thaiv- cov txheej txheem kev nyab xeeb ntawm cov kob. Qhov thib ob rov qab fais fab txaus sau npe, AC daim phiaj disconnect hloov qhib, thiab lub inverter's PWM tsav teeb liab kaw tag nrho. Qhov no rub DC tsheb npav capacitors thiab lub zog semiconductors rov qab los ntawm kev txaus ntshai overvoltage thiab thermal tawg.
Tsis siv neeg hloov pauv hloov (ATSE) cov tshuab: Thaum cov khoom siv hluav taws xob thiab lub tshuab hluav taws xob hloov hluav taws xob hloov lub sijhawm ua haujlwm tsis zoo tsim ib ntus circulating hla tam sim no, rov qab fais fab relays thaiv qhov tsis zoo ntawm kev hloov pauv. Cov khoom siv tiv thaiv luv luv ntawm cov khoom siv hluav taws xob sib cais thiab ua kom tsis zoo rau qhov lawv tsim tam sim.
Ntawm -Site System Implementation & Long-Term Operational Value
Peb lub zog zoo saib xyuas thiab cov chaw tiv thaiv kev sib txuas ua ke rov qab lub zog tiv thaiv raws li lub ntsaws - thiab - ua si modular feature rau kev ncaj nraim teb. Ib daim ntawv qhia tag nrho - xim qhia tau hais tias nyob plaub- cov ntaub ntawv hluav taws xob quadrant, cia cov neeg ua haujlwm tam sim ntawd paub qhov txawv ntawm lub zog rau pem hauv ntej thiab lub zog rov qab muaj kev phom sij ntawm ib pliag.
Tag nrho cov kev tiv thaiv tsis tau teeb tsa los ntawm software, nrog hloov kho kom haum rau cov me me diesel gensets ntsuas ntawm kaum tawm kilowatts mus txog rau ntau -megawatt hnub ci ua liaj ua teb. Cov cuab yeej teev cov ntaub ntawv tag nrho rau txhua qhov kev cuam tshuam rov qab fais fab, suav nrog kev ntes cov waveforms, qhov txhaum loj thiab tag nrho lub sijhawm rov qab ntws. Cov ntaub ntawv tiav no ua kom yooj yim tshaj tawm cov ntawv tshaj tawm -fault root- ua rau kev soj ntsuam los txheeb xyuas cov teeb meem xws li roj av ua haujlwm tsis zoo thiab kab sib chaws khi tswj tsis raug rau kev teeb tsa kev tiv thaiv tsis raug.
Tos kom tsis muaj kev tswj hwm rov qab fais fab ntws los rhuav tshem cov nqi hluav taws xob inverters, lub tshuab hluav taws xob thiab cov khoom siv tswj xyuas ua rau cov nqi qis thiab cov khoom hloov pauv. Txhim kho lub zog rov qab tiv thaiv kev tiv thaiv hauv koj lub kaw lus tswj lub txee muab kev ntseeg siab, puag ncig - lub - moos kev nyab xeeb. Los ntawm kev kuaj xyuas lub zog rov qab thiab kev sib txuas ntawm cov hluav taws xob hauv milliseconds, txheej txheej kev nyab xeeb no txuas ntxiv lub tshuab hluav taws xob thiab lub tshuab hluav taws xob inverter, txiav cov nqi kho tsis tau npaj tseg, thiab tiv thaiv koj qhov project fais fab hauv qab -kab nyiaj tau los ntev.
