Ntau dhau ntawm kev them nyiaj ev, cov neeg zej zog tuaj yeem nqa cov khoom thauj khoom?
Hauv cov neeg nyob ze hauv Shenzhen, thaum 20 tshiab nruab 7 degree, qhov ntsuas kub uas nthuav tawm qhov kev tiv thaiv lub zog tom qab lub luag haujlwm ntawm Evs. Cov ntaub ntawv hauv lub xeev qhia tias xyoo 2023, cov naj npawb ntawm kev them nyiaj rau cov neeg thaj chaw thoob plaws hauv 240% xyoo, thaum lub transformer sib txig perve los ntawm 57%. Qhov no "them lub kiv puag ncig" yog kuaj cov resilience ntawm lub nroog loj hauv nroog loj.
I. Tus "Zog Dub Dub" ntawm Piles Piles
Lub zog ntawm 7kW qeeb them pawg yog sib npaug rau 5 teeb tsa 3 hp cua txias khiav tib lub sijhawm. Yog tias lub zej zog muaj 5 {{{{{10} pawv tas nrho ntawm 350kw, superimposed ntawm cov neeg nyob hauv lub zog yooj yim (li 150kw), tag nrho cov load ntau dua li 500kw. 630KVA Hloov pauv kev ruaj ntseg thauj tau tsuas yog 504kW (630 × 0.8), lub sijhawm no lub kaw lus yog nyob rau verge ntawm vau.
Dab tsi txaus ntshai tshaj yog qhov cuam tshuam tam sim no ntawm kev them nyiaj sai sai. 120kW DC Cov Khoom Taw Qhia Ceev Tam Sim Ntawd, lub ncov tam sim no tuaj yeem nce mus txog 3 zaug ntawm tus nqi ntsuas, ua rau muaj hluav taws xob poob ntawm 15%. Kev ntsuas nyob hauv ib cheeb tsam hauv ib cheeb tsam hauv ib cheeb tsam hauv ib lub sijhawm ua haujlwm ntawm chav npav faib rau hauv chav tos npav kom poob los ntawm 320V, ua rau muaj kev ncua ntev ntawm cov khoom lag luam.
II.Qhov hloov pauv "triple tsim txom"
Thermal Kev Laus: Thaum lub load tus nqi tshaj 90%, transformer winding kub nce siab nce los ntawm 4 zaug. Ib lub koom haum kuaj xyuas lub chaw ua hauj lwm pom tsis pom kev ua haujlwm ntawm kev hloov pauv daim ntawv Polymerization los ntawm 900 txog 400, lub neej luv los ntawm 60%.
Harfonic Puring: Lub 5th thiab 7 Harmonics tau tsim los ntawm kev them cov neeg inverters nce transformer hlau poob los ntawm 35%. Tom qab lub zej zog hauv Shanghai ntxiv cov cuab yeej lim, cov nyiaj poob ib hlis poob ntawm 9.7% rau 4.2%.
Peb-theem tsis txaus: Ib leeg-theem nkag mus rau txoj kab them nyiaj coj mus rau ib txoj kab no tam sim no ntau dua 70a, thiab lub zej zog yog li muaj cable meltdown huam yuaj. Tom qab npaj cov thev naus laus zis hloov pauv hloov pauv, peb-theem tsis txaus tau nias los ntawm 45% mus rau 8%.
III.Thov txoj kev los ua kom tawg "plaub-seem program"
Muaj peev xwm hloov kho mis:
Them Pawg Pile tag nrho (KW) {{{{0} × transformer muaj peev xwm (kva transformer)}}} puage bead load (kw)
Piv txwv li: 630kva transformer rho tawm load, tag nrho cov nqi txawb hluav taws xob yog capped ntawm 241kw (txog {kW piles).
Intelligent Discatch System:
- Lub sijhawm sib koom: Siv lub Valley fais fab tuag (0. 3 RMB \/ KWRING thov rau 23: {}}}
- Kev faib hluav taws xob ntau zog dynic: cia li derate lub zog them nyiaj rau 4kW thaum tus nqi thauj mus los txog 85
Tom qab daim ntawv thov hauv ib lub zej zog hauv Hangzhou, qhov nruab nrab txhua hnub Transformer load tus nqi tau txo los ntawm 97% mus rau 72%.
Zog Cia Ua Pas Dej Ua:
Teeb tsa nrog 100kW \/ 200kW Lithphate Zog Khoom Siv Hluav Taws Xob, nws tuaj yeem ua tau raws li 20 lub tsheb thaum hmo ntuj. Lub Guangzhou Pilot Project qhia tau hais tias lub zog cia hluav taws xob txiav peak transformer thauj los ntawm 41%, nrog lub sijhawm them tsuas yog 4.2 xyoos.
Daim ntawv teev cov cuab yeej hloov kho:
1. Hloov cov amorphous alloy transformer (tsis muaj-thau khoom poob los ntawm 70%)
2. Ntxiv Syng Dynamic Reactive Fais Kev Them Nyiaj Ntaus (Felf Factor ntau dua lossis sib npaug {15)
3. Kho kom zoo rau 240 hli tooj liab tub ntxhais core cable (ntsaws muaj zog ntxiv rau 500a)
Iv.Qhov "Zog Neural Network" ntawm lub zej zog yav tom ntej
Lub v2g (lub tsheb-rau-phiaj kev sib tham) kev ua yeeb yam hauv Suzhou Industrial Park hloov pauv chaw nres tsheb txawb chaw nres tsheb. Thaum lub sij hawm Peak, cov tsheb tuaj yeem tawm mus txog 2mw ntawm Rauv hluav taws xob, sib npaug rau cov chaw tsim hluav taws xob me me. Qhov no "peak chais thiab Valley Filling" hom txhab ruaj tus nqi hloov pauv ntawm 65% {}}% ntawm cov khoom siv golden.
Lub xeev kev twv kwv yees tias muaj 2025 lub luag haujlwm them nqi ntse tuaj yeem txo tus nqi ntawm kev faib khoom network ntawm 23 billion yuan. Thaum peb ntsaws rau hauv lub tsheb them nyiaj rau lub tsheb, cov kev npaj ua kom zoo nkauj thiab kev tsim kho txuj ci ntse hauv lub zog ua haujlwm, txhawm rau ua kom muaj kev mus ncig ua si ntsuab "lub zog ntsuab".
