Raws li qhov hloov tau yooj yim thiab cov khoom siv hluav taws xob muaj txiaj ntsig, cov chaw tsim khoom microb tau siv hauv cov ntaub ntawv, kev lag luam thiab lwm cov chaw kho mob kom ntseeg tau lub zog tseem ceeb. Hauv microgrid microgrid, hwj huam hloov khoom yog ib qho ntawm cov tseem ceeb ntawm cov khoom sib xyaw ua ke thiab kev ntseeg tau. Ntawm lawv, zoo li qub hloov (STS) thiab tsis siv neeg hloov mus hloov (ATTS) yog ob lub zog hloov hluav taws xob hloov khoom siv. Lawv muaj qhov sib txawv tseem ceeb nyob rau hauv kev ua haujlwm, daim ntawv thov kev pab daws, thiab kev ua tau zoo. Kab lus no yuav delve rau hauv lub luag haujlwm thiab qhov sib txawv ntawm cov ss thiab atts hauv nruab nrab microgrid.
1 Dab tsi yog microgram
(1) Kev txhais thiab cov qauv ntawm microgrid
Lub microgrid yog lub zog me me thiab xa tawm cov ntaub ntawv hluav taws xob (xws li cov roj hluav taws xob, thiab lwm yam), thauj khoom, thiab cov khoom siv tshuaj xyuas thiab saib xyuas thiab tshuaj xyuas cov khoom siv. Nws tuaj yeem ua haujlwm nyob rau hauv parallel nrog lub hwj chim sib tw lossis ywj pheej nyob rau hauv hom Island
(2) Kev Lag Luam Hom ntawm Microgrid system
Daim phiaj sib txuas ua haujlwm hom: Hauv Daim Phiaj Kev Sib Koom Tes Ua Haujlwm, lub microgrid tau txuas nrog Microgrid tuaj yeem muab lub zog hluav taws xob. Kev siv hluav taws xob ntau dhau kuj tuaj yeem kis tau rau daim phiaj loj. Nyob rau tib lub sijhawm, thaum lub zog hluav taws xob tsis pub dhau lub microgrid tsis txaus, cov phiaj loj tuaj yeem muab kev txhawb nqa fais fab rau lub microgrid.
Kob ua hauj lwm pab pawg: thaum muaj kev txhaum lossis npaj lub zog hluav taws xob hauv lub pob sib koom ua ke, lub microgram tuaj yeem raug txiav tawm los ntawm lub zog hluav taws xob thiab nkag mus rau Island Office hom. Hauv kev ua haujlwm hauv paus kev lag luam hom, micrograms tso siab rau lawv tus kheej faib khoom siv rau cov khoom siv hluav taws xob hauv zos, ua kom muaj zog ntawm cov khoom lag luam tseem ceeb.
2 Lub ntsiab lus ntawm STS thiab ATTS
1. Li qub hloov pauv (STS)
Sts (Li qub hloov mus) yog lub hwj chim hloov ntaus ntawv raws li cov hluav taws xob hluav taws xob, feem ntau yog siv los ua kom tiav nrawm thiab hloov kho AC FRIDES. Nws cov ntsiab lus tseem ceeb suav nrog tus tswj hwm kev txawj ntse, cov neeg nrawm nrawm, thiab cov sib txuas sib tshuam.
2. Tsis Siv Neeg Hloov Hloov (ATTS)
ATS (tsis siv neeg hloov hloov mus) yog lub zog kho tshuab hluav taws xob hloov kho lub zog hluav taws xob kom hloov lub zog hluav taws xob los ntawm ib lub zog rau lwm lub hwj chim rau lwm tus. Hloov chaw ua haujlwm yog feem ntau cov neeg ua npe nkag lossis Circuit Court.
3 Lub luag haujlwm ntawm SMS thiab ATTS
(1) lub luag haujlwm ntawm ss
1. Hloov nrawm
CLS tuaj yeem hloov kho lub zog fais fab sai sai, nrog lub sijhawm hloov pauv tsis dhau 8\/4 lub voj voog (tsawg dua los yog sib npaug rau 5 milliseconds). Cov khoom siv nrawm nrawm ua haujlwm tsis muaj kev cuam tshuam ntawm cov khoom siv hluav taws xob, zam kev poob cov ntaub ntawv poob lossis khoom siv puas tsuaj los ntawm hluav taws xob.
2. Kev ntseeg siab
Lub zog fais fab BS yog tsim nyog rau cov ntawv thov uas yuav tsum muaj cov chaw zov me nyuam, kev sib txuas lus, txhim kho qhov rov qab los ntawm lub zog hluav taws xob.
3. Tau ntau nrog ntau lub zog hluav taws xob
SS tuaj yeem ua tiav kev hloov pauv ntawm UPS thiab UPS, UPS thiab Generator, muab kev txhawb nqa lub zog loj rau cov khoom siv hauv cov khoom siv hluav taws xob nyuaj.
(2) lub luag haujlwm ntawm ATSs
1. Kev hloov ceev rov qab
Nights tsuas yog siv hauv kev siv hluav taws xob muaj xwm txheej ceev. Thaum lub zog loj ua tsis tiav, nws tau hloov kho rau lub zog thaub qab kom ntseeg tau tias kev ua haujlwm tsis tu ncua ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb. Nws lub sijhawm hloov kho feem ntau yog 100 milliseconds, haum rau cov khoom uas yog insensitive luv luv hluav taws xob, xws li teeb pom kev zoo, lub teeb, thiab lwm yam.
2. Kev ntseeg tau ntawm cov qauv neeg kho tshuab
Cov kev pab tau npaj ua kev sib cuag kev hloov pauv, uas muaj cov kev tiv thaiv muaj zog thiab qhov siab hloov mus ua tiav. Nws cov qauv yog qhov yooj yim, tus nqi txij nkawm yog tsawg, thiab nws yog haum rau hloov cov khoom hnyav.
3. Siv dav
ATS tau siv dav hauv kev lag luam tsim, cov chaw zov me nyuam, tsev kho mob, tshwj xeeb tshaj yog nyob rau qhov chaw hloov chaw nrawm tsis siab.
4 Qhov sib txawv ntawm cov ss thiab ATTS
(1) hloov nrawm
BS: hloov ceev ceev yog qhov ceev heev, feem ntau ntawm 5 milliseconds thiab 8 milliseconds, haum rau cov khoom siv tau hais txog hluav taws xob.
ATS: Lub tshuab hloov ceev qeeb qeeb, feem ntau yog 100 milliseconds, thiab muaj peev xwm txawm mus txog 1.5 vib nas this, haum rau cov hluav taws xob tsis muaj zog.
(2) txoj kev hloov mus
BS: Siv hluav taws xob hloov khoom hluav taws xob (qhov nrawm nrawm thyristors) kom ua tiav hloov, tus txheej txheem hloov yog "uas tuaj yeem ua tiav txoj kev hloov tsis sib haum.
ATS: hloov mus ua tiav siv cov neeg kho tshuab (cov neeg sib cuag lossis cov txheej txheem Circuit Regers, thiab cov txheej txheem hloov pauv ntawm cov neeg kho tshuab, uas yuav ua rau cov hluav taws xob tshwj xeeb.
(3) Daim Ntawv Thov Kev Sau Npe
SS: Haum rau cov sijhawm uas muaj cov peev txheej siab heev rau cov ntaub ntawv, kev sib txuas lus hauv paus, cov twj paj nruag, thiab lwm yam.
ATS: Haum rau qee lub sijhawm uas tsis muaj kev nkag siab luv luv rau lub zog hluav taws xob, xws li kev tsim khoom, tsev kho mob, teeb tsa, thiab lwm yam.
(4) kev ntseeg tau
BS: Lub tshuab hluav taws xob hloov txoj kev ua rau nws nkag siab ntau dua rau cov kev cuam tshuam hluav taws xob xws li hluav taws xob daws teeb meem thiab ntsuas kub thiab kev nyab xeeb yog siab dua.
ATS: Cov kev sib ze hu hloov txoj kev ua rau nws muaj zog tiv thaiv kev cuam tshuam, tab sis kev ua txhaum yuav tshwm sim vim kev sib chwv hnav, qhov teeb meem nce thiab teeb meem huab cua sov.
(5) nqi thiab txij nkawm
STS: Cov cuab yeej siv tau yog qhov tseem ceeb, tab sis kev txij nkawm yooj yim.
ATS: Cov cuab yeej siv yog tus nqi qis, tab sis cov qauv cov neeg kho tshuab yuav tsum muaj kev tu ib txwm muaj.
5 lub ntsiab lus
SS, nrog nws cov txiaj ntsig ntawm kev hloov ceev thiab siab kev cia siab fais fab, yog qhov tsim nyog rau cov khoom siv ntsuas uas muaj kev nkag siab rau lub zog hluav taws xob; ATS, ntawm qhov tod tes, yog qhov tsim nyog rau cov khoom siv tsis txaus ntseeg uas tsis txaus ntseeg kom luv luv hluav taws xob vim nws cov kev ntseeg tau zoo thiab tus nqi qis. Hauv kev siv cov tswv yim, STS lossis ATTS yuav tsum tau raug xaiv raws li cov yam ntxwv xws li kev ua haujlwm ruaj khov ntawm microgrid cov tshuab thiab kev ntseeg tau ntawm lub zog fais fab.
