Daim phiaj {{3} Yam khoom siv hluav taws xob yeej tseem ceeb ntawm kev ntsuas hluav taws xob uas muaj hluav taws xob thiab cov khoom siv hluav taws xob ruaj khov thiab zaus¹.

Grid - Hauv qab hluav taws xob cia: nws ua haujlwm ntawm cov kab sib chaws thiab cov pob zeb hluav taws xob nrog cov kab sib chaws los ntawm theem- xauv cov voj (pll) thev naus laus zis. Daim phiaj - Cov hluav taws xob cia hauv qab yog qhov tseem ceeb tam sim no cov peev txheej tam sim no thiab tsis tuaj yeem muab cov hluav taws xob ntau ntxiv los ntawm lawv tus kheej. Lawv yuav tsum cia siab rau ntawm qhov hluav taws xob thiab cov zaus ntawm lub hwj huam sib chaws¹.

2.Control lub tswv yim

Grid - Kev tsim lub zog hluav taws xob, tswj hwm lub zog hluav taws xob zoo ib yam li theem thiab qhov tseeb ntawm cov zis hluav taws xob. Daim phiaj - Cov tswv yim Converter tuaj yeem ua haujlwm nyob rau hauv parallel lossis tawm {{daim phiaj kev sib tw. Thaum txhawb nqa cov khoom sib xyaw ua ke lossis muaj peev xwm rov qab muaj peev xwm rov qab, Daim phiaj Kev Hloov Pauv kuj tseem tuaj yeem muab ververia thiab damping rau lub system².

Grid - Hauv qab hluav taws xob Cia: Nws txoj kev tswj hwm tau txais cov phiaj xwm thiab theem lub kaum sab xis tam sim no txhaj rau hauv lub hwj huam sib chaws. Grid-} Cov hloov pauv hauv qab no nyob rau ntawm daim phiaj fais fab thiab yuav tsum ua haujlwm hauv parallel. Lawv tsis tuaj yeem muab cov hluav taws xob thiab cov nyiaj tau los ntawm lawv tus kheej².

3. Cov yam ntxwv ntawm cov yam ntxwv

3.1Grid - sib haum hluav taws xob cia

Tshaj dhau lub peev xwm: daim phiaj - hom hluav taws xob cia khoom muaj peev xwm ua haujlwm ntev ntawm 110% ntawm cov ntaus nqi tam sim no. Thaum muaj 120% ntawm qhov ntsuas nyob tam sim no, lub sijhawm ua haujlwm txuas ntxiv yuav tsum tsis pub tsawg tshaj li 2 feeb. Ntawm 150% ntawm cov ntaus nqi tam sim no, lub sijhawm ua haujlwm txuas ntxiv yuav tsum tsis pub tsawg tshaj 1 feeb, thiab ntawm 300% ntawm qhov ntsuas nyob tam sim no, lub sijhawm ua haujlwm txuas ntxiv yuav tsum tsis pub tsawg tshaj 10 vib nas this³.

Cov kev txhawb nqa hluav taws xob nquag: Koom nrog cov hluav taws xob hluav taws xob ntawm lub zog hluav taws xob thiab muab luv luv {{} lub sij hawm reasive fais fab txhawb lub sijhawm thaum lub sij hawm hloov chaw. Grid - hom hluav taws xob cia tshuab, thiab kuj muaj cov peev xwm ua hluav taws xob zoo ib yam li cov khoom muaj zog sab hauv muaj peev xwm thiab hluav taws xob voltage³.

Luv - Circuit Court tam sim no txhawb nqa: Grid - Hom Zog Tam Sim No, thiab nws qhov peev xwm tshaj peb yuav tsum tsis pub tsawg tshaj peb zaug. Lub sijhawm ua haujlwm tas mus li yuav tsum tsis pub tsawg tshaj 10 vib nas this. Lub sijhawm luv - Circuit Court txhawb kev txhawb nqa ntawm Grid {}} Cov Txheej Txheem Zog ntawm lub peev xwm ntawm cov hloov pauv thiab hloov pauv ntau yam. Thaum ntau cov tshuab muaj kev ua haujlwm nyob rau hauv parallel, lub voj voos ntawm tam sim no ntawm lub tshuab nquag yog tsawg dua 5%³.

3.2Grid - Hauv qab hluav taws xob cia

Nyob ntawm daim phiaj phiaj teeb: nws txoj kev tswj hwm yog zaus nyob ntawm qhov zaus thiab kev ntsuas hluav taws xob ntawm lub zog rau kev cai. Qhov no txhais tau tias hauv grid - kev tswj hwm hluav taws xob hauv paus yog "kev tswj hwm lub zog tsuas yog muab kev pab cuam ntxiv rau lub hwj huam sib luag⁴.

Kev tswj hwm hluav taws xob: Feem ntau yog siv rau zaus kev cai, thauj khoom sib npaug, kev hloov kho lub zog, thiab cov khoom siv hluav taws xob hloov kho lossis lub zog txuas ntxiv tsis ruaj khov⁴.

4.strengts thiab tsis muaj zog

Cov txiaj ntsig: Nws muaj peev xwm kho tau nws cov txiaj ntsig hauv lub sijhawm los ntawm kev mob nkeeg uas tsis muaj lub zog hluav taws xob tsis muaj sab nraud. Los ntawm kho cov khoom siv hluav taws xob, nws tswj hwm cov hluav taws xob tawm, cov ntaub ntawv xaiv voltage qhov sib txuas, thiab ua kom lub system ruaj khov. Tsis tas li ntawd, hauv lub zog hluav taws xob tsis muaj zog yam tsis muaj qhov hluav taws xob ruaj khov, nws tuaj yeem tsim lub zog ywj siab⁵.

Qhov tsis zoo: qhov muaj peev xwm overcurrent ntawm daim phiaj- kev ua kom 3.0 zaug, yog li tus nqi siab dua li ntawm cov kab sib txuas no⁵.

4.2Grid - Hauv qab hluav taws xob cia

Qhov zoo: Cov qauv kev tswjhwm yog yooj yim, thiab theem - Xauv cov cuab yeej thev naus laus zis ntawm tam sim no. Yog li ntawd, lub kaw lus tuaj yeem tswj tau raws li qhov xwm txheej uas tam sim no thiab lub zog siab tshaj plaws ntawm cov kab ke raug txiav txim⁵.

Qhov tsis zoo: Txawm hais tias theem {- Xauv cov thev naus laus zis zoo nkauj thiab cov hluav taws xob tau muab los ntawm lub zog sib thooj los ua haujlwm ib txwm muaj. Ntxiv mus, qhov ruaj khov ntawm nws tus kheej tswj lub zog yog tsis muaj zog dua li ntawm grid {2} Tsis muaj zog rau cov loops, thiab nws tsis tuaj yeem ua lub luag haujlwm hauv kev txhawb nqa cov kab ke⁵.

5.Aplevication scenarios

5.1rid - sib haum zog cia

Lub zog hluav taws xob tsis muaj zog lossis thaj chaw thaum kawg ntawm cov fais fab ntawm cov teeb meem: Lub cheeb tsam fais fab phiaj xwm kab ke yog qhov tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj zog, nrog kev hloov pauv tsis muaj peev xwm. Lub zog tshiab muaj ntau tab sis cov thauj khoom thov qis, ua cov teeb meem ruaj khov uas muaj tshwm sim. Grid {{2} Kev tsim lub zog hluav taws xob tuaj yeem txhim kho lub zog ntawm cov grids {}} zaj muaj zog thiab nqa lub peev xwm tshiab⁶.

Muab cov kev pab cuam tshuam: Hauv kev ua lag luam hluav taws xob yav tom ntej, kev sib tw ntawm nws cov peev txheej nrawm thiab ntau yam kev txhawb nqa, thiab tau txais txiaj ntsig⁶.

5.2 Daim phiaj - hauv qab hluav taws xob cia

Daim phiaj xwm txheej thiab kev txiav txim siab: Nws tuaj yeem teb sai rau cov kev hloov pauv hauv daim phiaj xwm thiab thauj khoom, thiab kho cov kev tso tawm ntawm cov hluav taws xob lub zog⁴.

Lub Hwj Chim Grid Qhov Chaw: Los ntawm kev ua haujlwm hauv synchronization nrog lub hwj huam kev pab rau kev hloov pauv hauv kev sib tw fais fab xwm⁴.

Load Ntsuas Ntsuas: Muab kev txhawb nqa lub zog:⁴.

Zuag qhia tag nrho, grid - Cov hluav taws xob cia rau cov khoom seem uas tau zoo thiab tsis muaj kev txhawb nqa ntau dua thiab kev txhawb nqa ntau zaus. Piv txwv li, nyob rau hauv loj loj hauv nroog fais fab ci, vim yog lub zoo-}} Cov pob zeb tsim nyog tuaj yeem siv tau cov phiaj xwm ntawm cov khoom siv hluav taws xob¹.

6.Qhov khoom siv txuas ntxiv

Nrog kev nce qib txuas ntxiv ntawm kev nkag mus rau lub zog tshiab, kev hloov pauv ntawm "ua raws li kev tsim kho" los ua ib qho ntawm kev tsim kho yav tom ntej ntawm lub zog cia thev naus laus zis⁷.

Raws li cov thev naus laus zis tawm, grid- cov teeb meem kev sib zog hauv kev lag luam, ntsib cov kev sib tw xws li tsis muaj cov qauv sib koom tes⁷.

Grid {{0} Txoj kev sib sau ua kom muaj zog cia Tshuab yog qhov tseem ceeb yuav tsum txhawb kev tsim kho lub zog hluav taws xob tshiab. Txhawm rau hais txog cov kev cov nyom uas tau coj los ntawm "dual {2} Kev sib sau ua ke, kev sib cav sib ceg ntawm lub zog, thiab kev sib cav sib ceg tsawg ntawm cov hluav taws xob ruaj khov, voltet stability, thiab lub zog lub kaum sab xis⁷.

Yav tom ntej, nrog kev nce qib ntawm thev naus laus zis thiab kev txo qis ntawm cov nqi, grid} Cov Txheej Txheem Tseem Ceeb rau lub zog sib pauv mus rau qhov kev sib pauv siab dua ntawm kev faib tawm dua tshiab⁷.
