Kev tsom xam ntawm cov tub ntxhais muaj nuj nqi ntawm PV nodes hauv cov nyiaj hli zoo li qub (SVG)

Nyob rau hauv daim teb ntawm lub zog tswj kev tswj hwm, tus pv node ua hauj lwm raws li lub luag haujlwm tseem ceeb rau cov pv voltage (svg), thiab yog dab tsi yog qhov kev txiav txim siab ntawm pv

Kuv {. tswj txoj ntsiab cai ntawm PV nodes

Lub PV ntawm hom ntawm cov static vari bisator (SVG) yog hais txog kev sib txuas ntawm kev sib txuas tas los ntawm kev tswj hwm cov hluav taws xob tawm {}}

1. voltage kaw-LOP kev cai kaw, sib piv nrog cov lus qhia lub tsheb npav, thiab ntau tiam ntawm cov lus qhia hluav taws xob {}}
{{02. teb sai sai mechanism: lub zog sai sai ntawm igbt tuaj yeem kho cov khoom siv hluav taws xob reactive hauv milliseconds.
3.}}}} kev sib koom tes ntau: ua tiav voltage kev cai thaum tseem xav txog cov haujlwm ua kom zoo xws li Harmonic lim.

Thaum lub kaw lus voltage flacking, cov zoo li cov neeg them nyiaj ntau dua los ntawm kev txhawb nqa hluav taws xob tau cuam tshuam nrog cov kev txhawb nqa hluav taws xob tau cuam tshuam nrog cov kev txhawb nqa hluav taws xob tau cuam tshuam nrog cov kev txhawb nqa hluav taws xob tau txhim kho kev ua haujlwm ntawm cov tsev txhab nyiaj tau ntau nrawm

Ii {. Daim ntawv thov ntawm Fais Fab Lub Zog Hluav Taws Xob

PV node ua haujlwm ntawm cov neeg muaj pes tsawg tus roj ntsha

1. voltage ronpressed supression: mitigating hloov voltage: kev hloov pauv sai sai ntawm cov zis ntawm photovoltaic lossis cua lub zog .
2.} Tsawg-voltage caij-los: muab kev txhawb zog hluav taws xob zoo li lub sij hawm sib tsoo
3.} Cov Faction Faction: Txhim kho cov hluav taws xob cuam tshuam thaum lub zog txwv kev ua haujlwm
{{04. Kev Reponance Damping: Suppressing Sub-synchronous oscillations los ntawm Lub Zog Tshiab Lub Zog

Qhov chaw nres tsheb tiag tiag ntawm 200MW photoovoltaic lub chaw nres tsheb fais fab qhia tau hais tias tus neeg ntsuas hluav taws xob zoo li qub (SVG) tau sib txuas tau tuaj yeem khaws cov phiaj xwm txuas ntxiv hauv ± 1% conflication .

III {. Daim Ntawv Thov Kev Muaj Zog Hluav Taws Xob Hluav Taws Xob

Hauv cov xwm txheej muaj xwm txheej, pv ntawm cov haujlwm uas muaj cov teeb meem zoo:

1. Qhov Cuam Tshuam Luv Khoom Them Nyiaj: Kev txhim kho ntawm cov flicker tshwm sim los ntawm cov mills, thiab lwm yam.
2. voltage Tassee poob cov paj meuvent: Qhov kev paub tseeb zoo rau cov khoom siv tseem ceeb
{{03. Txoj Kev Ua Haujlwm Ua Haujlwm: Tswj cov qauv hluav taws xob qhov tseeb hauv qab distorted Waveforms
4. Lub Zog Zog Ua Kom Zoo: Los ntawm kev tswj hwm hluav taws xob, txo cov kab poob qis.
