xob laim tawm tsam ua rau muaj teeb meem loj hauv UK daim phiaj hluav taws xob, thiab roj teeb lub zog cia cov tshuab qhia lawv cov txuj ci ntawm lub sijhawm tseem ceeb
Thaum Lub Yim Hli 9th, Tebchaws Askiv poob 1.5GW ntawm lub peev xwm tsim hluav taws xob vim yog xob laim ntawm lub zog xa hluav taws xob, ua rau muaj hluav taws xob cuam tshuam rau ntau dua 1 lab tsev neeg, uas tsuas yog rov qab zoo li qub tom qab 50 feeb. Daim ntawv tshaj tawm tshiab tau taw qhia tias yog tias tsis muaj lub zog cia roj teeb lub zog cawm, qhov cuam tshuam yuav ntev dua. Hnyav thunderstorms ua rau muaj kev puas tsuaj thiab xob laim nyob rau hauv cov kab sib kis thiab xa tawm ntawm UK. Ntxiv nrog rau kev txo cov kab hluav taws xob ntau zaus (lub zog zaus), kuj tseem muaj hluav taws xob tsis tshua muaj hluav taws xob. Lub Rhein Group (RWE) Me Barford Natural Gas Fais fab cog nrog lub peev xwm ntawm 660MW dheev nres ua haujlwm thaum 4:52 teev tsaus ntuj. 45 vib nas this tom qab, Hornsea Ib, lub ntiaj teb' qhov loj tshaj plaws offshore cua ua liaj ua teb, kuj ua tsis tiav, thiab 1.5GW hluav taws xob poob hauv 1 feeb. Cov kab hluav taws xob Cov zaus qis dua qhov kev nyab xeeb ua haujlwm zaus.
Daim phiaj zaus yog qhov qhia txog qhov sib npaug ntawm cov khoom siv thiab kev thov, qhia qhov zaus ntawm AC lub zog ntawm daim phiaj. Hauv tebchaws Askiv, hom oscillation no tshwm sim 50 zaug ib ob, yog li daim phiaj feem ntau siv 50 Hz. Qhov zaus hauv UK tau poob mus rau 48.9 Hz thaum lub sijhawm ntawd. Qhov qis dua, qhov nyuaj dua yog rau cov chaw tsim hluav taws xob ib txwm siv los pub hluav taws xob rau hauv daim phiaj.
Tim Gree, tus thawj coj ntawm Energy Futures Laboratory ntawm Imperial College London, tau hais tias qhov no yog vim qhov kev ua haujlwm ntawm lub tshuab hluav taws xob loj yuav poob qis vim qhov zaus tsawg zuj zus, uas tseem yog qhov muaj peev xwm tswj tsis tau. Lub tuam txhab British National Electricity Supply Company (National Grid) cuam tshuam cov khoom siv hluav taws xob ntawm 5% ntawm cov tsev neeg kom ntseeg tau tias kev siv hluav taws xob zoo li qub rau 95%.
Txawm li cas los xij, lub roj teeb lub zog cia qhov system tsis txwv los ntawm ntau zaus, tsuav yog cov khoom siv tau qhib thiab lub zog xa tawm ntawm 50Hz fais fab zaus kom tig cov dej ntws. Lub Tuam Txhab Hluav Taws Xob Hauv Tebchaws ntawm Tebchaws Askiv tau hais tias thaum lub sijhawm hluav taws xob hluav taws xob, lub roj teeb lub zog khaws cia nrog tag nrho lub peev xwm ntawm 475 MW tau ua tiav ntau yam.
Qhov loj tshaj plaws tso zis yog lub photovoltaic fais fab nroj tsuag ze London Luton tshav dav hlau, nruab nrog ib tug tag nrho ntawm 6MW lithium roj teeb lub zog cia system. Tus neeg saib xyuas lub tuam txhab hluav taws xob Upside Energy tau hais tias cov roj teeb muab lub zog rau hauv daim phiaj ntawm qhov nrawm thib ob. Txawm hais tias 6MW suab zoo, lub peev xwm zoo ib yam li qhov nruab nrab cua turbine. Yog tias tsev neeg nruab nrab siv qhov nruab nrab ntawm 2000W, 6MW tuaj yeem ua tau raws li qhov xav tau ntawm 3000 tsev neeg.
Tsis tas li ntawd, lub roj teeb ntawm British tus tsim hluav taws xob tauj dua tshiab RES muab 80MW hluav taws xob nyob rau lub sijhawm tseem ceeb. RES tau hais tias daim phiaj zaus tau poob qis ntawm tus nqi ntawm 0.144 Hz ib ob, tab sis lub roj teeb pib them tsis pub dhau 25 vib nas this thiab hloov los ntawm hom kev them nqi mus rau hom tawm, pab rov qab qhov zaus.
Thaum kawg, nrog kev pab los ntawm ntau tog, daim phiaj zaus tshaj 50Hz thaum 4:57 teev tsaus ntuj. Lub Tuam Txhab Hluav Taws Xob Hauv Tebchaws tau taw qhia tias nws siv sijhawm 3 feeb thiab 47 vib nas this rau lub roj teeb lub zog khaws cia kom rov qab tau cov kab sib txuas kom zoo li qub, ntau dua 11 feeb kaum xyoo dhau los. Txawm sai dua. Qhov xwm txheej no zoo ib yam li 2017 Tesla roj teeb hauv South Australia. Thaum lub sij hawm ntawd, thaum lub sij hawm lub thermal fais fab nroj tsuag tripped, Tesla roj teeb xa 100MW ntawm hluav taws xob mus rau daim phiaj nyob rau hauv ib tug ceev heev 140 milliseconds, qhia tau hais tias lub zog cia system muaj txiaj ntsig zoo rau kev ruaj ntseg ntawm daim phiaj.
