Substation Digital Interface
Daim ntawv thov ntawm substation comprehensive automation technology nyob rau hauv lub hwj chim system tau mature rau xyoo lawm. Cov neeg vam khom ntau thiab ntau dua ntawm automation coj peb yooj yim. Qhov tsis zoo ntawm cov cuab yeej siv niaj hnub tsis tuaj yeem hloov mus rau txoj kev loj hlob ntawm lub zog tam sim no. Qhov sib txawv ntawm qhov chaw nres tsheb automation tam sim no, qhov chaw nres tsheb digital muaj lwm yam ntxwv: lub photoelectric transformer txais lub hauv paus ntsiab lus ntawm Rogowski coil yog lub ntsiab feature ntawm lub photoelectric transformer yog cov qauv yooj yim, me me, lub teeb yuag, dav ct dynamic ntau yam, tsis muaj saturation tshwm sim, Tsis muaj resonance, theem nrab tso zis tsis ntshai ntawm qhib Circuit Court, cov zis cov yam ntxwv. substation
Feem ntau, nws tuaj yeem muab faib ua ob hom: nquag thiab passive. Active photoelectric transformers, uas yog, lub taub hau sensor yuav tsum tau ntxiv "zog" los yog "zog" fais fab mov, thiab siv fiber ntau optical xa cov ntaub ntawv, uas yog ib qho yooj yim mus cuag high precision thiab siab ntseeg ntawm hluav taws xob circuits. Qhov nyuaj yog nyob rau hauv lub hwj chim mov ntawm tej thaj chaw deb siv technology thiab kev tswj fais fab, lub sij hawm ntawm lub cev muaj zog yog txwv, lub sij hawm ntev-lub zog laser fais fab mov yuav cuam tshuam rau lub neej ntawm optoelectronic cov cuab yeej, thiab nws yog raug rau electromagnetic cuam tshuam. Tus kheej-excited transformer tsis xav tau ib tug passive photoelectric transformer nrog rau sab nraud fais fab mov. Qhov nyuaj yog Yuav ua li cas txo qhov "tsim" lub kaum ntse ntse, siv lead ua birefringence, fiber ntau polarization cuam tshuam, qhov dav ntawm qhov kub thiab txias.
Vim hais tias nws muaj peev xwm hais tias cov pa transformers thiab photoelectric transformers nyob rau tib lub sij hawm, los yog photoelectric transformers yog peb-theem AC, lub ntsiab transformer yuav tsum tau txais cov ntaub ntawv nyob rau hauv lub ncua sij hawm ntawm txawv voltage sab rau sib txawv kev tiv thaiv, busbars yog sib txawv ntawm txawv lub sij hawm, sib txawv. kev tiv thaiv ntawm ob sab ntawm txoj kab, thiab cov cuab yeej kev nyab xeeb yog synchronized Cov kev xav tau ntawm cov ntaub ntawv tau txais thiab kev faib tawm ntawm point-to-point fiber optic network ua rau qhov tshwm sim ntawm cov hubs tshwj xeeb. Cov khoom siv ntse hauv substation yuav tsum xub muaj qhov digital interface. Ib qho khoom siv yog qhov ntsuas pom lub voj voog thiab tswj kev tsav tsheb. Nws yog tsim los nrog microprocessor thiab photoelectric technology. Qhov thib ob Circuit Court thiab nws cov logic Circuit Court ntawm lub substation ntawm cov pa relay yog hloov los ntawm ib tug programmable maub los. Cov pa muaj zog tam sim no analog teeb liab thiab hloov cov tswj cable los ntawm photoelectric serial tooj thiab optical fiber. substation
Muab cov ntaub ntawv hluav taws xob rau cov khoom siv hluav taws xob los ntawm cov txheej txheem tsheb thauj mus los, tau txais cov lus txib xws li tripping thiab kaw ntawm cov khoom siv bay, input hloov txoj hauj lwm, tsis tshua muaj hluav taws xob, thiab rooj vag txoj hauj lwm ntawm txhua lub Circuit Court breaker ntse davhlau ya nyob twg, thiab tso zis dhia commands, suav nrog tswj circuits, lub ntsiab lub cev txawj ntse terminals nkag mus rau hauv wireless hluav taws xob, nruab nrab taw tes riam txoj hauj lwm, iav txoj hauj lwm thiab lwm yam teeb liab tso zis txoj hauj lwm tswj, nruab nrab taw tes riam txoj hauj lwm tswj thiab kiv cua tswj kev sib cuag, cov khoom ntse yog ib tug ntxiv ua ke ntawm mechatronics. substation
