Hauv plawv ntawm txhua lub chaw tsim hluav taws xob hydropower, deb ntawm lub suab nrov ntawm cov turbines thiab lub zog loj heev ntawm cov penstocks, muaj ib qho chaw ntsiag to: lub vaj huam sib luag tswj. Cov ntxaij vab tshaus, cov qhov hloov pauv, cov cim qhia, thiab cov tswj hwm no yog lub hlwb ntawm tag nrho kev ua haujlwm, kom ntseeg tau tias lub zog muaj zog ntawm dej tau hloov mus ua hluav taws xob txhim khu kev qha thiab muaj txiaj ntsig zoo.
Cov Haujlwm Tseem Ceeb
Lub luag haujlwm tseem ceeb ntawm lub vaj huam sib luag tswj hwm yog los muab ib qho chaw sib txuas lus rau kev saib xyuas thiab kev txib txhua yam txheej txheem tseem ceeb hauv lub Hoobkas. Nws cov haujlwm tseem ceeb tuaj yeem faib ua peb qhov tseem ceeb:
Kev Soj Ntsuam thiab Kev Tau Txais Cov Ntaub Ntawv: Lub vaj huam sib luag tswj hwm tau txais cov ntaub ntawv tiag tiag los ntawm ntau pua lub sensors thoob plaws hauv qhov chaw. Qhov no suav nrog:
Cov Kev Ntsuas Hluav Taws Xob: Cov zis ntawm lub tshuab hluav taws xob (voltage, current, frequency, power factor), qhov xwm txheej ntawm transformer, thiab qhov chaw ntawm lub circuit breaker.
Xwm Txheej Txheem Kho Tshuab: Qhov ceev ntawm lub turbine (RPM), qhov chaw ntawm lub qhov rooj wicket, qhov kub ntawm lub bearing, thiab qib kev co.
Cov xwm txheej hydraulic: Cov dej hauv lub pas dej thiab cov dej hauv qab, qhov chaw ntawm lub qhov rooj ntawm lub pas dej, thiab cov nqi ntws hauv cov pas dej.
Kev Tswj thiab Kev Ua Haujlwm: Los ntawm lub vaj huam sib luag, cov neeg ua haujlwm tuaj yeem ua cov lus txib kom meej los tswj cov txheej txheem tsim hluav taws xob. Qhov no suav nrog:
Pib thiab Nres cov chav turbine-generator.
Synchronizing lub generator nrog lub grid hluav taws xob.
Kho qhov hnyav los ntawm kev tswj lub qhov rooj wicket kom tswj tau qhov dej ntws, phim lub zog tso zis nrog qhov xav tau ntawm lub grid.
Kev siv cov tshuab pabcuam xws li cov twj tso dej txias, cov tshuab lubrication, thiab cov compressor units.
Kev Tiv Thaiv thiab Kev Nyab Xeeb: Qhov no tej zaum yog qhov tseem ceeb tshaj plaws. Lub vaj huam sib luag tswj hwm tau koom ua ke nrog lub kaw lus tiv thaiv zoo uas ua rau lub tswb ceeb toom thiab pib kaw cov kab ke yog tias muaj qhov ntsuas twg tshaj qhov txwv kev nyab xeeb. Qhov no tiv thaiv kev puas tsuaj loj heev rau cov khoom siv, xws li kev ua tsis tiav ntawm lub tshuab los ntawm kev khiav ceev dhau lossis kev ua txhaum hluav taws xob.
Cov Cheebtsam Tseem Ceeb ntawm Lub Vaj Huam Sib Luag Niaj Hnub
Txawm hais tias cov chav tswj hwm ib txwm muaj cov phab ntsa loj ntawm cov nyees khawm tawv, teeb, thiab cov ntsuas analog, cov vaj huam sib luag niaj hnub tau hloov zuj zus:
Kev Sib Txuas Lus Tib Neeg-Tshuab (HMI): Cov ntxaij vab tshaus kov loj, muaj kev daws teeb meem siab tam sim no yog qhov ib txwm muaj. Lawv qhia txog cov duab qhia txog tag nrho cov nroj tsuag, uas tso cai rau cov neeg ua haujlwm pom cov txheej txheem thiab nkag mus rau hauv cov kab ke tshwj xeeb nrog kev kov ib zaug xwb.
Cov Tswj Xyuas Logic Programmable (PLCs) thiab SCADA: Cov no yog lub hauv paus ntse. PLCs yog cov khoos phis tawj kev lag luam uas ua cov kev tswj hwm logic raws li cov lus qhia los ntawm cov sensors. Lawv tau sib txuas ua ke rau hauv Supervisory Control and Data Acquisition (SCADA) system, uas muab lub platform software hauv nruab nrab rau kev sau cov ntaub ntawv, kev tshuaj xyuas keeb kwm, thiab kev tswj hwm chaw taws teeb.
Cov Relays Tiv Thaiv: Cov khoom siv hluav taws xob tshwj xeeb no tiv thaiv cov khoom siv tshwj xeeb (generators, transformers). Lawv saib xyuas cov xwm txheej hluav taws xob tas li thiab tuaj yeem ua rau cov circuit breakers tawg hauv milliseconds kom paub qhov txhaum.
Cov Vaj Huam Sib Luag Tshaj Tawm: Cov no muab cov lus ceeb toom pom thiab hnov tam sim ntawd, tsis meej pem txog qhov ua yuam kev loj, kom ntseeg tau tias cov neeg ua haujlwm yuav tsis plam lub tswb ceeb toom tseem ceeb txawm tias thaum saib xyuas ntau lub vijtsam.
Kev Hloov Pauv: Los ntawm Analog mus rau Digital
Kev taug kev ntawm cov vaj huam sib luag tswj hwm ua piv txwv rau kev hloov pauv thev naus laus zis dav dua. Thaum ntxov xyoo pua 20th cov vaj huam sib luag yog analog tag nrho, vam khom kev sib txuas lus lub cev thiab cov xov hlau nyuaj. Niaj hnub no, cov txheej txheem digital muab cov txiaj ntsig tsis muaj qhov sib piv:
Kev Ua Haujlwm Zoo Dua: Cov txheej txheem tswj hwm tsis siv neeg ua kom zoo dua qhov kev ua tau zoo kom muaj zog ntau tshaj plaws.
Kev Tshawb Xyuas Zoo Dua: Kev tshuaj xyuas cov ntaub ntawv siab heev pab kwv yees qhov xav tau kev saib xyuas, txo lub sijhawm tsis ua haujlwm.
Kev Ua Haujlwm Nyob Deb: Tam sim no ntau lub Hoobkas tuaj yeem saib xyuas thiab tswj tau los ntawm qhov chaw hauv nruab nrab, ua rau muaj kev ywj pheej ntau dua thiab txo qhov xav tau neeg ua haujlwm hauv tsev.
Xaus lus
Lub vaj huam sib luag tswj hwm ntawm lub chaw tsim hluav taws xob hydropower tsis yog tsuas yog ib pawg ntawm cov khawm yooj yim xwb. Nws yog ib lub kaw lus ntse uas sib xyaw ua ke uas hloov cov hluav taws xob hydropower nyoos mus ua lub zog huv uas ruaj khov thiab xa tau. Los ntawm kev muab cov neeg ua haujlwm nrog lub qhov muag, pob ntseg, thiab tes los tswj cov zog loj heev, cov vaj huam sib luag tswj hwm no yog qhov tseem ceeb rau kev ntseeg tau thiab kev ruaj khov ntawm peb lub zog niaj hnub no, kom ntseeg tau tias qhov chaw siv hluav taws xob no ua tau raws li qhov xav tau ntawm lub xyoo pua 21st.
