Chidule:

Pa Juni 21, 2022, tsamba la Unduna wa Zanyumba ku China ndi Urban-Rural Development linatulutsaKhodi Yamapangidwe a Electrochemical Energy Storage Station (Zokonzekera Ndemanga). Khodi iyi idalembedwa ndi China Southern Power Grid Peak ndi Frequency Regulation Power Generation Co., Ltd. komanso makampani ena, omwe amakonzedwa ndi Unduna wa Zanyumba ndi Kutukuka kwa Mizinda-Kumidzi. Muyezowu ukuyenera kugwiritsidwa ntchito popanga malo atsopano, okulitsidwa kapena osinthidwa a electrochemical energy storage station ndi mphamvu ya 500kW ndi mphamvu ya 500kW·h ndi kupitilira apo. Ndi mulingo wokakamiza wadziko lonse. Tsiku lomaliza la ndemanga ndi Julayi 17, 2022.

Zofunikira pa Mabatire a Lithium:

Muyezowu umalimbikitsa kugwiritsa ntchito mabatire a lead-acid (lead-carbon), mabatire a lithiamu-ion ndi mabatire oyenda. Kwa mabatire a lithiamu, zofunikira ndi izi (potengera zoletsa zamtunduwu, zofunikira zokha ndizo zomwe zalembedwa):

1. Zofunikira zaumisiri za mabatire a lithiamu-ion ziyenera kutsatiridwa ndi zomwe zikuchitika mdziko munoMabatire a Lithium-ion Ogwiritsidwa Ntchito Posungira MphamvuGB/T 36276 ndi mulingo wamakono wamakampaniZaukadaulo Za Mabatire a Lithium-ion Ogwiritsidwa Ntchito mu Electrochemical Energy Storage StationNB/T 42091-2016.

2. Mphamvu yamagetsi ya lithiamu-ion batri modules iyenera kukhala 38.4V, 48V, 51.2V, 64V, 128V, 153.6V, 166.4V, etc.

3. Zofunikira zaukadaulo za kasamalidwe ka batire la lithiamu-ion ziyenera kugwirizana ndi zomwe zikuchitika mdziko munoZaukadaulo Za Mabatire a Lithium-ion Ogwiritsidwa Ntchito mu Electrochemical Energy Storage StationGB / T34131.

4. Njira yamagulu ndi topology yolumikizira ya batri iyenera kufanana ndi mawonekedwe a topology ya chosinthira chosungira mphamvu, ndipo ndikofunikira kuchepetsa kuchuluka kwa mabatire olumikizidwa mofanana.

5. Dongosolo la batri liyenera kukhala ndi zida za DC, ma switch switch ndi zida zina zodulira ndi chitetezo.

6. DC mbali voteji ayenera kutsimikiziridwa molingana ndi makhalidwe batire, voteji kukana mlingo, ntchito kutchinjiriza, ndipo sayenera kukhala apamwamba kuposa 2kV.

Ndemanga ya Mkonzi:

Muyezo uwu ukukambitsirana, zolemba zofananira zitha kupezeka patsamba lotsatirali. Monga muyezo wokakamiza wadziko lonse, zofunikirazo zidzakhala zovomerezeka, ngati simungathe kukwaniritsa zofunikira za muyezo uwu, kukhazikitsidwa kwapambuyo pake, kuvomereza kudzakhudzidwa. Ndikofunikira kuti makampani azidziwa zofunikira za muyezo, kuti zofunikira za muyezo zitha kuganiziridwa pagawo la kapangidwe kazinthu kuti muchepetse kukonzanso kwazinthu pambuyo pake.

Chaka chino, China yakhazikitsa ndikusintha malamulo angapo ndi miyezo yosungiramo mphamvu, monga kukonzanso kwa GB/T 36276 standard, Twenty-fine Requirements for Prevention of Power Production Accidents (2022) (chithunzi cha ndemanga) (onani m'munsimu kuti mudziwe zambiri), Kukhazikitsidwa kwa Chitukuko Chatsopano Chosungirako Mphamvu Zatsopano mu Pulani ya 14 ya Zaka zisanu, ndi zina zotero. Miyezo iyi, ndondomeko, malamulo amachitira chithunzi ntchito yofunikira ya mphamvu. kusungirako m'dongosolo lamagetsi, pamene zikusonyeza kuti pali zolakwika zambiri mu mphamvu yosungirako mphamvu, monga electrochemical (makamaka lithiamu batire) yosungirako mphamvu, ndipo China idzapitirizabe kuganizira zolakwa izi.
