Distribution Automation Terminal (DAT) ua haujlwm ua haujlwm ntawm kev faib khoom siv hluav taws xob thiab yog ib qho tseem ceeb ntawm lub kaw lus. Nws feem ntau saib xyuas thiab tswj cov khoom siv hloov pauv hauv qhov system faib khoom thiab muab kev ua haujlwm xws li qhov chaw txhaum thiab kev cais tawm, nrog rau kev tiv thaiv kab ke.
Distribution automation terminals feem ntau muab faib ua peb hom: Feeder Terminal Units (FTUs), Distribution Substation Terminal Units (DTUs), thiab Transformer Terminal Units (TTUs). Nyob ntawm daim ntawv thov scenario, FTUs feem ntau yog ntsia rau ntawm cov khoom siv hluav taws xob los sau cov ntaub ntawv hloov pauv ntawm cov hluav taws xob hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam khoom siv. Cov ntaub ntawv xwm txheej no raug xa mus rau lub sijhawm tiag tiag mus rau qhov chaw nres tsheb tus tswv ntawm wireless transceiver modules. Nyob rau hauv qhov kev tshwm sim ntawm ib tug txhaum, FTU kuj tswj cov khoom sib txuas sib txuas raws li cov lus txib los ntawm lub chaw nres tsheb tswv.
Thaum lub sijhawm teeb tsa, ib qho FTU feem ntau yog siv los saib xyuas ib tus ncej -mounted hloov. Thaum ob kab txuas rau ntawm tib tus ncej, txhawm rau txo cov nqi, ob lub FTU tuaj yeem raug tsim los ua tus tswv - qhev configuration, qhov twg tus tswv FTU sib txuas lus ncaj qha nrog tus tswv chaw nres tsheb, thaum tus qhev FTU sib txuas lus nrog tus tswv chaw nres tsheb indirect ntawm tus tswv FTU.
Raws li daim ntawv thov scenarios, cov terminals faib tam sim no siv nyob rau hauv kev faib automation feem ntau poob rau hauv pawg hauv qab no:
(1) Feeder Terminal Unit (FTU): Lub chaw xa khoom xa tawm tau nruab rau ntawm cov khoom siv hluav taws xob lossis cov chaw zoo sib xws nrog cov khoom siv hluav taws xob sib txuas, nruab nrog cov teeb liab chaw taws teeb, ntsuas cov chaw taws teeb, thiab cov chaw taws teeb tswj kev ua haujlwm;
(2) Distribution Terminal Unit (DTU): Lub chaw xa khoom xa tawm tau teeb tsa hauv cov chaw hloov pauv, chav faib khoom, lub nplhaib tseem ceeb, lossis cov chaw ntim khoom ntim hauv cov khoom siv hluav taws xob sib txuas, nruab nrog cov chaw taws teeb qhia, ntsuas chaw taws teeb, thiab kev tswj chaw taws teeb;
(3) Transformer Terminal Unit (TTU): Ib lub davhlau ya nyob twg siv rau kev saib xyuas thiab ntsuas ntau yam kev ua haujlwm ntawm cov khoom xa tawm.
Nyob ntawm lawv cov dej num thiab thaj tsam ntawm daim ntawv thov, cov khoom siv hluav taws xob faib hluav taws xob tuaj yeem muab faib ua hom hauv qab no:
1. Lub zog saib xyuas Terminals: Lub luag haujlwm tseem ceeb hauv kev sau cov ntaub ntawv los ntawm ntau yam khoom siv hluav taws xob hauv kev faib khoom, ua kom muaj tseeb - lub sijhawm saib xyuas thiab sau cov ntaub ntawv hais txog kev ua haujlwm, kev siv hluav taws xob, kev thauj khoom, thiab kev ua haujlwm tsis raug, yog li ua kom muaj kev nyab xeeb thiab ruaj khov ntawm kev faib khoom network.
2. Tswj Terminals: Feem ntau yog lub luag haujlwm rau kev ua haujlwm hauv chaw taws teeb thiab kev tswj hwm ntawm ntau yam khoom siv hluav taws xob hauv qhov kev faib khoom, yog li ua kom zoo dua qub thiab txhim kho kev tswj hwm kev lag luam thiab cov txheej txheem kev lag luam ntawm kev faib khoom.
3. Kev sib txuas lus Terminals: Cov no yog lub luag haujlwm tseem ceeb rau kev hloov cov ntaub ntawv sib pauv ntawm ntau lub davhlau ya nyob twg, ua kom cov ntaub ntawv xa mus thiab kev sib txuas lus ntawm lawv, thiab yog li ua kom muaj kev ruaj khov thiab ua haujlwm tsis siv neeg thiab tswj cov khoom siv hluav taws xob.
4. Zaub Terminals: Cov no yog lub luag haujlwm tseem ceeb rau kev nthuav tawm thiab tshuaj xyuas cov ntaub ntawv thiab cov ntaub ntawv los ntawm lub zog faib hluav taws xob. Lawv ua cov ntaub ntawv khaws cia rau hauv cov ntaub ntawv sib xws uas tso tawm ntawm cov ntxaij vab tshaus rau cov neeg ua haujlwm saib thiab txheeb xyuas, ua kom muaj tseeb - lub sijhawm saib xyuas cov khoom siv hluav taws xob thiab ceeb toom ntxov ntawm ntau yam kev tsis sib haum xeeb.
5. Integrated Terminals: Cov terminals no ua ke cov dej num ntawm cov lus hais saum toj no thiab muaj peev xwm faib hluav taws xob automation tswj, ua rau lawv yog pawg tseem ceeb tshaj plaws ntawm cov terminals hauv lub zog faib hluav taws xob. Los ntawm lawv tus kheej logic tswj muaj peev xwm, cov terminals pauv cov ntaub ntawv nrog lub computer network kom ua tiav kev tswj xyuas kev ua haujlwm ntse thiab kev tswj xyuas.
6. Cov neeg siv khoom Terminal: Feem ntau muab kev pabcuam rau cov neeg siv khoom lag luam thiab kev lag luam, suav nrog - lub sijhawm saib xyuas kev siv hluav taws xob, kev siv hluav taws xob, thiab cov lus pom zoo rau kev siv hluav taws xob zoo. Los ntawm cov neeg siv khoom davhlau ya nyob twg, cov neeg siv tau yooj yim nkag mus rau cov ntaub ntawv ntawm kev siv hluav taws xob ntawm cov khoom siv hluav taws xob, yog li ua tiav kev txuag hluav taws xob thiab txo nqi.
Hauv cov ntsiab lus, cov hluav taws xob faib hluav taws xob automation terminals tuaj yeem muab faib ua ntau hom raws li lawv txoj haujlwm thiab cov peev txheej ntawm daim ntawv thov, suav nrog lub zog saib xyuas cov khoom siv hluav taws xob, tswj cov terminals, kev sib txuas lus terminals, cov khoom siv hluav taws xob, cov khoom siv sib txuas, thiab cov neeg siv khoom.
