1. Qhov project Overview

Qhov project no nyob rau hauv Ghana, Africa, thiab ua haujlwm ua qhov chaw ua qauv qhia kev lag luam uas suav nrog kev tsim hluav taws xob los ntawm lub hnub ci, kev khaws cia roj teeb, thiab kev them hluav taws xob rau lub tsheb. Tsim los rau kev ua haujlwm them EV, qhov chaw nres tsheb tau dhau los ua qhov chaw ua yeeb yam hauv cheeb tsam rau kev siv hluav taws xob huv.

Lub tshuab hluav taws xob hauv zos muaj peev xwm tsuas yog 120 kVA xwb . Vim muaj peev xwm tsawg ntawm lub network thiab hluav taws xob tsis ua haujlwm ntau zaus, cov khoom siv hluav taws xob uas twb muaj lawm tsis tuaj yeem txhawb nqa txhua qhov chaw them hluav taws xob uas ua haujlwm ntawm lub zog tag nrho, ua rau lub chaw them hluav taws xob muaj peev xwm thiab kev ua haujlwm zoo tsis zoo.

Yuav kom daws tau ob qho tib si qhov tsis txaus ntawm lub grid thiab kev muab hluav taws xob tsis txhim khu kev qha, tus neeg siv khoom tau xaiv peb lub txee cia hluav taws xob roj teeb 125 kW/261 kWh , ua ke nrog lub STS static transfer switch thiab lub photovoltaic carport system.

Nyob rau hauv cov xwm txheej ib txwm muaj ntawm lub network, lub hnub ci system, lub roj teeb cia, thiab lub network hluav taws xob ua haujlwm ua ke los txhawb cov khoom siv them fais fab kom muaj zog tag nrho. Yog tias lub network tsis ua haujlwm, lub system ua tiav kev hloov pauv ntawm kev txuas nrog lub network mus rau kev ua haujlwm tawm ntawm lub network hauv ib vib nas this. Cov khoom them ceev ceev DC muaj zog heev yuav raug kaw ib ntus, thaum lub system txuas ntxiv muab hluav taws xob rau cov khoom siv them AC li ntawm 5-8 teev , kom ntseeg tau tias cov kev pabcuam them fais fab tseem ceeb tseem muaj.

2. Cov ntsiab lus ntawm qhov project

2.1 Daim Ntawv Thov

Qhov project no yog ib qho kev siv lag luam ib txwm muaj ntawm lub hnub ci-cia-EV them hluav taws xob.

Lub chaw them fais hauv Ghana ntsib peb qhov teeb meem loj:

• Kev xav tau them siab tshaj plaws
• Muaj peev xwm tsawg hauv zos
• Kev siv hluav taws xob tsis txhim khu kev qha

Kev cia siab rau lub zog fais fab xwb yuav tsis tuaj yeem txhawb nqa txhua yam khoom siv them hluav taws xob uas ua haujlwm tib lub sijhawm. Kev txhim kho lub peev xwm ntawm lub transformer ib txwm yuav xav tau kev nqis peev ntau thiab kev tsim kho thiab kev pom zoo ntev.

Lub chaw nres tsheb photovoltaic tsim hluav taws xob huv ncaj qha ntawm qhov chaw, thaum lub kaw lus khaws cia roj teeb ntxiv rau lub grid thaum lub sijhawm xav tau them ntau. Lub kaw lus kuj tseem muab kev hloov pauv thaum muaj xwm txheej ceev ceev thaum lub grid tsis ua haujlwm.

Cov kev daws teeb meem no txhawb nqa kev them nqi puv ntoob hauv qab qhov xwm txheej ib txwm muaj thaum tseem tswj hwm cov kev pabcuam them nqi tseem ceeb thaum muaj kev cuam tshuam hluav taws xob. Nws txo qhov kev vam khom rau hluav taws xob ntawm cov tuam txhab hluav taws xob, txo cov nqi khiav lag luam, thiab tshwj xeeb tshaj yog tsim rau cov chaw them nqi EV lag luam hauv thaj chaw Africa uas muaj cov hluav taws xob tsis muaj zog lossis tsis ruaj khov.

3. Cov Txiaj Ntsig Tseem Ceeb ntawm Qhov Project

3.1 Kov yeej qhov kev txwv ntawm lub zog hluav taws xob

Lub tshuab khaws cia hluav taws xob 125 kW/261 kWh ntxiv rau qhov kev muab hluav taws xob tsawg, ua rau lub chaw them hluav taws xob ua haujlwm tau zoo txawm tias lub transformer 120 kVA uas twb muaj lawm muaj peev xwm txwv.

3.2 Kev Sib Koom Tes ntawm Lub Hnub Ci, Kev Khaws Cia, thiab Kev Ua Haujlwm ntawm Lub Grid

Lub tshuab photovoltaic, lub tshuab khaws roj teeb, thiab lub network hluav taws xob ua haujlwm ua ke nrog kev txawj ntse los txhawb kev xav tau them hluav taws xob. Qhov no ua rau kev siv lub zog hnub ci huv si ntau ntxiv thiab txo cov hluav taws xob uas yuav los ntawm lub network.

3.3 Ua Haujlwm Txuas Ntxiv Thaum Lub Fais Fab Tsis Ua Haujlwm

Lub STS ua rau muaj kev sib txuas nrog lub grid thiab kev hloov pauv tawm ntawm lub grid sai. Thaum lub sijhawm tsis muaj hluav taws xob, lub kaw lus tuaj yeem txuas ntxiv muab cov khoom siv them AC li ntawm 5-8 teev, kom ntseeg tau tias cov kev pabcuam them hluav taws xob tseem ua haujlwm tau.

3.4 Cov Nqi Tsim Kho Vaj Tse thiab Kev Ua Haujlwm Tsawg Dua

Cov kev daws teeb meem no zam kev siv nyiaj ntau thiab lub sijhawm siv ntev uas cuam tshuam nrog kev txhim kho lub tshuab hluav taws xob. Kev siv hluav taws xob los ntawm lub hnub, kev txhawb nqa thaum muaj hluav taws xob ntau, thiab kev khaws cia hluav taws xob kuj pab txo cov nqi hluav taws xob thiab kev siv nyiaj ua haujlwm mus sij hawm ntev ntawm lub chaw nres tsheb.
