Lub ntsuas hluav taws xob yog dab tsi?
- Nws yog ib qho khoom siv uas ntsuas cov hluav taws xob siv hluav taws xob hauv tsev, kev lag luam lossis ib qho khoom siv hluav taws xob.
Active Zog - lub zog tiag tiag;ua haujlwm (W)
Consumer - kawg-siv hluav taws xob;lag luam, vaj tse
Kev siv - tus nqi ntawm lub zog siv thaum lub sij hawm them nqi.
Kev thov - tus nqi zog uas yuav tsum tau tsim nyob rau hauv ib lub sijhawm.
Zog - tus nqi ntawm lub zog siv nyob rau hauv ib lub sij hawm.
Load Profile - sawv cev ntawm qhov sib txawv ntawm qhov hluav taws xob load piv rau lub sijhawm.
Fais fab - tus nqi ntawm lub zog hluav taws xob ua haujlwm.(V x I)
Reactive - tsis ua hauj lwm, siv los magnetize motors thiab transformers
Tariff - nqi hluav taws xob
Tariffication – lub sij hawm ntawm cov nqi los yog cov nqi uas muaj feem xyuam rau qhov tau txais hluav taws xob los ntawm cov chaw muab kev pab.
Threshold – ncov tus nqi
Utility - lub tuam txhab fais fab

Instantaneous Values
- tuaj yeem nyeem tus nqi tam sim no ntawm cov hauv qab no: voltage, tam sim no, lub zog, lub zog thiab qhov xav tau.
Sijhawm-ntawm-siv (TOU)
- Teem sijhawm npaj txwv kev siv hluav taws xob raws li lub sijhawm nruab hnub
Cov neeg siv khoom nyob
Cov neeg siv khoom lag luam loj
Vim li cas thiaj siv TOU?
a. Txhawb kom cov neeg siv khoom siv hluav taws xob thaum lub sijhawm tsis nco qab.
- qis
- luv nqi
b.Pab cov nroj tsuag hluav taws xob (generators) kom sib npaug ntawm cov khoom siv hluav taws xob.
Load Profile
Lub Sijhawm Teev Sijhawm (RTC)
- siv rau qhov tseeb system lub sij hawm rau meters
- muab lub sijhawm muaj tseeb thaum lub sijhawm tshwj xeeb / qhov xwm txheej tshwm sim hauv lub ntsuas.
- suav nrog lub sijhawm thaj tsam, xyoo leap, lub sijhawm synchronization thiab DST
Kev sib txuas ntawm Relay thiab Disconnection
- koom nrog thaum lub sijhawm tswj kev ua haujlwm load.
- txawv hom
- tuaj yeem tswj manually, hauv zos lossis nyob deb.
