CHIWONJEZERO CHA ukadaulo: Pepala Loyera Lokhazikika la MIDA Power Infrastructure

Chowonjezera ichi chimagwira ntchito ngati maziko aukadaulo okwanira a mndandanda wa MIDA Power DC Fast Charging. Chimapatsa ma CPO (Charge Point Operators), oyang'anira magalimoto, ndi omwe amaika ndalama mu zomangamanga chidziwitso chakuya cha zida, mapulogalamu, ndi malamulo omwe amafotokoza mndandanda wazinthu za MIDA za 2026.

I. Kapangidwe ka Zipangizo: Fiziki ya Kusintha Kwambiri

Pakati pa siteshoni iliyonse ya MIDA DC pali malo osinthira magetsi pogwiritsa ntchito ukadaulo waposachedwa kwambiri wa semiconductor wa wide-bandgap. Kusintha kwathu kuchokera ku Silicon IGBTs yachikhalidwe kupita kuMa MOSFET a Silicon Carbide (SiC)ikuyimira kusintha kwa mphamvu ndi kulimba mtima kwa kutentha.

1.1 SiC MOSFET Topology ndi LLC Resonant Converters

Ma module amphamvu a MIDA a 30kW ndi 40kW amagwiritsa ntchitoMlatho Wonse Wosinthidwa Gawo (PSFB)kuphatikiza ndiChosinthira cha Resonant cha LLCsiteji. Kapangidwe kameneka kamalolaKusintha kwa Zero Voltage (ZVS)pamtundu wonse wa katundu. Mwa kuchotsa kutayika kwa kusinthana panthawi yoyatsa magetsi, timapeza mphamvu yosinthira ya 96.5%. Kugwiritsa ntchito zipangizo za SiC kumalola ma frequency osinthira opitilira 100kHz, zomwe zimachepetsa kwambiri kuchuluka kwa zinthu zamaginito monga ma transformer ndi ma inductors, zomwe zimapangitsa kuti kabati ikhale yaying'ono popanda kuwononga mphamvu yotulutsa magetsi.

1.2 Kuziziritsa ndi Kusamalira Kutentha kwa Mpweya Wopatukana

M'mafakitale ndi m'mabizinesi, kulephera kwa zamagetsi nthawi zambiri kumachitika chifukwa cha kuipitsidwa kwa chilengedwe. MIDA engineering yakhala ikutsogolera"Mapayipi Opatukana a Mpweya"kapangidwe kake. Chipinda chamkati chimagawika mopanda mpweya: ma semiconductor amphamvu ndi maginito amaziziritsidwa kudzera mu ngalande ya mphepo yothamanga kwambiri, pomwe ma control logic, ma module olumikizirana, ndi HMI zimasungidwa mu chipinda chotsekedwa, chopanda fumbi. Izi zimatsimikizira kuti ngakhale mu IP54 kapena IP55-rated outdoor installations, fumbi loyendetsa kapena chinyezi sizingalumikizane ndi mabasi amagetsi amphamvu.

II. Gawo la Luntha: Algorithm ya Kukonza Ndondomeko ya Mphamvu ya AI-DES

Kuchaja kwamakono sikungokhudza kupereka ma kilowatts osaphika okha, koma ndi nkhani yokhudza kukonza mphamvu mwanzeru.AI-DES (Kukonza Ndondomeko ya Mphamvu Yosinthika ya AI)Nsanjayi imagwira ntchito pa dongosolo la mfundo zitatu:

• Gawo 1: Kuyankha kwa Gridi-Mphepete:Chojambuliracho chimayang'anira ma gridi apafupi ndi ma voltage transients pamlingo wa 10kHz. Ngati kusakhazikika kwa gridi kwapezeka, makina a AI-DES amatha kuletsa kutulutsa kwamagetsi mkati mwa 20ms kuti apewe kusuntha kwa ma circuit breaker, zomwe zimagwira ntchito ngati chotetezera kwa wopereka chithandizo.
• Gawo 2: Kukonza Magalimoto Pakati pa Galimoto:Pogwiritsa ntchito ISO 15118 “Plug & Charge” telemetry, makina a AI-DES amakambirana njira yabwino kwambiri yolipirira ndi BMS ya galimotoyo. Amawerengera kutentha kwa batri, momwe zinthu zilili (SoH), komanso kukana kwamkati kuti aletse kukalamba msanga kwa maselo a lithiamu.
• Gawo 3: Kuyang'anira Zachuma:Pa malo akuluakulu osungiramo zinthu, dongosololi limagwirizana ndi misika yamagetsi. Limaika patsogolo kuyitanitsa zinthu pa nthawi ya mitengo yotsika ndipo lingagwiritse ntchito Battery Energy Storage Systems (BESS) kuti lichite "Peak Shaving," kupewa ndalama zambiri zomwe zimayikidwa ndi magetsi nthawi ya ntchito.
