Daim ntawv thov ntawm SVG zoo li cov neeg siv hluav taws xob hauv lub photovoltaic

Raws li tus nqi nkag siab ntawm photovoltaic muaj hwj chim tseem nce, cov cai ntawm lub zog hluav taws xob rau kev siv fais fab thiab voltage stability tau dhau los nruj. Lub SVG (static var them nyiaj) nrog nws cov millisecond-qib teb qhia pom qhov ua kom tau zoo iR.placholly tau txais txiaj ntsig zoo.

I. Kev tswj hwm kev kho lub zog hluav taws xob los ntawm photovoltaic inverters

SVG li cas cov fais fab hluav taws xob cov nyiaj them nqi thiab photovoltaic inverter daim ntawv ib qho kev cai tswj hluav taws xob nrog cov txiaj ntsig tau zoo:

1. Kev Ua Haujlwm Tshwj Xeeb Kev Ua Haujlwm: Lub SVG Static Reactive Fais Fab Lub Hluav Taws Xob (lub sijhawm sib tham tsawg dua lossis sib npaug rau cov kev txwv ceev) {2}} ms).
2. Kev Tsim Nyog Cov Qauv Ua Haujlwm Zoo Tshaj: Cov Inverter muab cov hluav taws xob ua kom nrawm nrawm nrawm nrawm nrawm nrawm dua hauv cov hluav taws xob nrawm.
3. Kev tswj kev tswj hwm lub tswv yim: Kev faib khoom siv fais fab tau ua tiav los ntawm PQ-V Droop tswj.

Ii. Voltage ruaj khov ntawm qhov kev sib txuas ntawm photovoltaic fais fab chaw

Lub SVG static reactive fais fab nyiaj them rov qab yog lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm lub thawv hluav taws xob:

1. Kev nrawm nrawm ntawm voltage hloov pauv: thaum lub zog hluav taws xob tshwm sim los ntawm huab npog lossis lwm yam, muaj lub zog uas muaj kev tiv thaiv tsis pub dhau 10 milliseconds.
2. Hmo ntuj voltage txoj cai hom kev cai: thaum lub sij hawm tsis muaj photuav hluav taws xob muaj peev xwm capinitive reactive fais fab txhawb nqa kom tswj tau cov kab voltage.
3. Harmonic Them Ua Haujlwm: Tshem tawm cov kev ua kom zoo nkauj siab tsim los ntawm Inverter (thd <3%).

III. Kev txhim kho ntawm lub zog zoo hauv photovoltaic kev txom nyem kev txom nyem Hwjchim

Nyob rau hauv cov chaw nyob deb nroog nrog lub zog hluav taws xob tsis muaj zog, SVG zoo li realic refactive fais fab nyiaj them yug:

1. Kev txhawb nqa hluav taws xob tsawg: los ntawm kev siv cov hluav taws xob muaj zog txhawb nqa, lub davhlau ya nyob voltage yog nce los ntawm {1}}%.
2. Peb-theem tsis txaus: Cov theem them-mais kev them nyiaj muaj peev xwm ua kom muaj kev tsis txaus ntseeg tias qhov tsis txaus ntseeg tsawg dua 2%.
3. Hwj chim Factor ua raws cai: tswj theem ruaj khov saum toj no 0. 98

IV. Transient voltage Txhawb rau cov khoom loj photovoltaic fais fab

Hais txog qhov teeb meem hluav taws xob hloov hluav taws xob thaum lub zog hloov chaw, SVG Static Var them nyiaj tau muab:

1. Tsawg voltage caij-los ntawm cov peev xwm: tuaj yeem ua haujlwm txuas ntxiv rau 1000ms thaum lub zog hluav taws xob mus rau 20%.
2. Dynamic Voltage Rov Qab: Qhov voltage yuav rov qab los rau 9 0% ntawm tus nqi rated tsis pub dhau 0.5 vib nas this.
3. Kev Kho Dua Sas Rov Qab Tom Qab Ua Haujlwm: Pab hauv cov txheej txheem rov qab ruaj khov
