Cov khoom siv hluav taws xob thib ob yog qhov tseem ceeb ntawm lub zog hluav taws xob, ua kom muaj kev saib xyuas, tswj, kev tiv thaiv, thiab kev sib pauv ntaub ntawv nrog cov cuab yeej tseem ceeb. Txawm li cas los xij, hauv kev siv tshuab ua haujlwm, nws tuaj yeem muab faib ua ntau hom raws li qhov sib txawv ntawm qhov chaw ua haujlwm, qib kev thov, thiab daim ntawv thev naus laus zis. Txhua yam khoom siv muaj nws tus yam ntxwv raws li nws qhov kev ua haujlwm, txoj kev siv, thiab kev ua haujlwm. Kev nthuav qhia qhov sib txawv no pab rau kev xaiv kom raug thiab tsim nyog tsim nyog thaum lub sij hawm npaj, tsim kho, thiab ua haujlwm thiab tu.
Los ntawm kev pom kev ua haujlwm, qhov sib txawv tseem ceeb nyob hauv qhov sib txawv ntawm kev saib xyuas thiab tswj cov khoom siv. Cov cuab yeej saib xyuas tsom mus rau kev sau, nthuav tawm, thiab sau cov txheej txheem kev ua haujlwm tseem ceeb, xws li lub zog xa hluav taws xob, ntsuas cov cuab yeej, thiab cov xwm txheej saib xyuas cov terminals. Nws hais txog qhov raug thiab txuas ntxiv ntawm cov ntaub ntawv, muab cov ntaub ntawv tseem ceeb rau kev soj ntsuam kev ua haujlwm thiab kev txiav txim siab- ua. Cov cuab yeej tswj hwm, ntawm qhov tod tes, tsom mus rau kev ua haujlwm thiab kev hloov pauv ntawm cov cuab yeej tseem ceeb, xws li cov chaw taws teeb tswj chaw taws teeb, cov tswj hluav taws xob tsis siv neeg, thiab cov khoom siv hluav taws xob hloov pauv. Nws yuav tsum tau ua kom tiav cov lus txib sai thiab ntseeg tau thaum tau txais lawv kom ua tiav qhov kev hloov kho ntawm lub xeev system.
Hauv kev tiv thaiv, cov khoom siv thib ob tau muab faib ntxiv rau hauv kev tiv thaiv thawj zaug thiab kev tiv thaiv thaub qab. Cov cuab yeej tiv thaiv tseem ceeb yog tsim los rau cov cuab yeej tshwj xeeb lossis kab, xav tau cov lus teb ceev ceev thiab kev xaiv siab, xws li kab longitudinal differential kev tiv thaiv thiab kev tiv thaiv tsheb npav sib txawv, tsom rau kev sib cais meej ntawm thawj theem ntawm kev ua txhaum. Cov cuab yeej tiv thaiv thaub qab ua haujlwm thaum qhov kev tiv thaiv thawj zaug tsis ua haujlwm lossis ua haujlwm tsis zoo, muab kev tiv thaiv dav dua thiab lub sijhawm teb qeeb, xws li kev tiv thaiv overcurrent thiab xoom- kev tiv thaiv ib ntus, cuam tshuam qhov sib npaug ntawm kev rov ua dua thiab kev ntseeg tau.
Los ntawm kev nkag siab txog qib kev thov, muaj qhov sib txawv tseem ceeb ntawm substation -theem thiab xa tawm -theem ob cov khoom siv. Substation-theem cov cuab yeej ncaj qha hais txog cov cuab yeej tseem ceeb hauv cov chaw tsim hluav taws xob thiab cov chaw ua haujlwm substations, hais txog kev ua tau zoo tiag tiag - lub sijhawm ua haujlwm thiab lub peev xwm ua haujlwm hauv zos, xws li bay - qib kev tiv thaiv thiab tswj cov cuab yeej thiab cov khoom siv ntse. Dispatch-theem cov cuab yeej, nyob rau hauv lub zog hluav taws xob xa tawm chaw lossis chaw tswj hwm cheeb tsam, sib sau cov ntaub ntawv los ntawm ntau lub chaw nres tsheb thiab ua tiav kev soj ntsuam thoob ntiaj teb thiab kev txiav txim siab zoo, xws li kev tswj hwm hluav taws xob (EMS) thiab dav - cheeb tsam ntsuas tshuab (WAMS), tsom ntau dua ntawm cov ntaub ntawv fusion thiab kev sib koom ua haujlwm nyob deb.
Nyob rau hauv cov nqe lus ntawm daim ntawv technical, muaj qhov sib txawv tseem ceeb ntawm cov khoom siv thib ob ib txwm siv thiab cov khoom siv digital / ntse ntse. Cov qub (thawj lub tshuab hluav taws xob) feem ntau yog tsim los ntawm cov khoom siv hluav taws xob tsis sib xws lossis cov khoom siv hluav taws xob, ua rau muaj qhov loj dua, txoj hlua txuas, thiab kev nthuav dav dav. Cov tom kawg (thib ob lub zog hluav taws xob) yog raws li microprocessors thiab embedded systems, ua kom tiav qib siab ntawm kev sib koom ua ke ntawm cov ntaub ntawv tau, kev ua haujlwm logic, thiab kev sib txuas lus. Lawv txhawb cov txheej txheem txheej txheem xws li IEC 61850, muaj tus kheej - kuaj mob, kho tau, thiab muaj peev xwm hloov kho tej thaj chaw deb, txhim kho kev sib raug zoo thiab kev txawj ntse.
Tsis tas li ntawd, raws li kev teeb tsa ib puag ncig, lawv tuaj yeem muab faib ua hom sab hauv tsev thiab sab nraum zoov. Cov qub muaj cov kev xav tau qis dua rau kev tiv thaiv kev tiv thaiv thiab kub thiab av noo adaptability, thaum lub tom kawg yuav tsum tau txhim khu kev ya raws, plua plav tsis kam, ntsev tsuag tsis kam, thiab dav - qhov kub thiab txias muaj peev xwm ua haujlwm, thiab muaj zog dua thiab nyob rau hauv cov tsos thiab qauv.
Hauv cov ntsiab lus, qhov sib txawv ntawm cov cuab yeej siv hluav taws xob theem nrab tau tshwm sim hauv ntau qhov ntev xws li kev faib ua haujlwm, qib kev tiv thaiv, daim ntawv thov, thiab kev siv tshuab. This differentiated design allows the secondary system to meticulously cover the various needs of primary equipment while forming a hierarchical, collaborative, and efficient operating system, providing a solid guarantee for the safe and reliable operation of the power system.
