1. Project Overview

Chirongwa ichi chiri kuGhana, Africa, uye chinoshanda senzvimbo yekuratidzira mabhizimisi inosanganisira kugadzirwa kwesimba rezuva, kuchengetwa kwesimba remabhatiri, uye kuchaja mota dzemagetsi. Yakagadzirirwa mabasa ekuchaja magetsi emagetsi, chiteshi ichi chave nzvimbo yekuratidzira nharaunda yekushandisa simba rakachena.

Transformer yemuno ine simba re120 kVA chete . Nekuda kwekusakwana kwegrid uye kudzimwa kwemagetsi nguva nenguva, grid iripo haigone kutsigira nzvimbo dzese dzekuchaja dzinoshanda nesimba rakazara, zvichideredza zvakanyanya kugona kwekuchaja kwechiteshi uye kushanda zvakanaka kwacho.

Kuti tigadzirise kusakwana kwegrid pamwe nemagetsi asina kuvimbika, mutengi akasarudza kabhineti yedu yekuchengetera simba rebhatiri ye125 kW/261 kWh , pamwe chete neSTS static transfer switch uye photovoltaic carport system.

Mumamiriro ezvinhu akajairwa egrid, solar system, bhatiri storage system, uye utility grid zvinoshanda pamwe chete kutsigira michina yekuchaja iri pamagetsi akazara. Kana grid ikadzima, system inopedzisa shanduko kubva pagrid-connected kuenda ku off-grid operation mukati mesekondi imwe chete. MaDC fast chargers ane simba guru anodzimwa kwenguva pfupi, nepo system ichiramba ichipa simba kuAC charging equipment kweinenge maawa mashanu kusvika masere , zvichiita kuti mabasa ekuchaja arambe aripo.

2. Project Details

2.1 Chikumbiro

Chirongwa ichi chinoshandiswa zvakanyanya mukutengeserana kwemagetsi ezuva akabatanidzwa ekuchaja magetsi emagetsi emagetsi.

Nzvimbo yekuchaja muGhana yakatarisana nematambudziko makuru matatu:

• Kudiwa kwekuchaja kwepamusoro-soro
• Kukwanisa kwegridi yemunharaunda kushoma
• Simba remagetsi risingavimbike

Kuvimba chete negrid yemagetsi kwaisagona kutsigira michina yese yekuchaja inoshanda panguva imwe chete. Kuvandudzwa kwesimba re transformer kwakajairika kwaizoda mari yakawanda uye kuvaka kwakareba uye kubvumidzwa.

Nzvimbo yemagetsi inoburitsa magetsi akachena zvakananga panzvimbo iyi, ukuwo sisitimu yekuchengetedza simba remabhatiri ichibatsirawo grid panguva dzekuchaja zvakanyanya. Sisitimu iyi inopawo shanduko nekukurumidza panguva yekudzima kwegrid.

Mhinduro iyi inotsigira mashandiro ekuchaja zvizere mumamiriro ezvinhu akajairwa ukuwo ichichengetedza mabasa ekuchaja akakosha panguva yekukanganiswa kwemagetsi. Inoderedza kuvimba nemagetsi emagetsi, inoderedza mari yekushandisa, uye inonyanya kukodzera nzvimbo dzekuchaja dzemagetsi dzekutengeserana munzvimbo dzeAfrica dzine magridi emagetsi asina kusimba kana asina kugadzikana.

3. Zvakanakira Zvikuru zvePurojekiti

3.1 Inokunda Miganhu Yekugona Kwegrid

Sisitimu yekuchengetera simba ye125 kW/261 kWh inowedzera huwandu hushoma hwemagetsi, zvichiita kuti nzvimbo yekuchaja ishande zvakanaka pasinei nekukwanisa kushoma kwetransformer iripo ye120 kVA.

3.2 Kushanda Kwakabatana Kwezuva, Kuchengeta, uye Grid

Sisitimu yemagetsi inobuda nemagetsi, sisitimu yekuchengetera mabhatiri, uye grid yemagetsi zvinoshanda pamwe chete nehungwaru kutsigira kudiwa kwekuchaja. Izvi zvinowedzera kushandiswa kwesimba rezuva rakachena uye zvinoderedza magetsi anotengwa kubva pagrid.

3.3 Kushanda Nguva Dzose Panguva Yekudzimwa Kwemagetsi

STS inobvumira kushandura grid nekukurumidza uye kunze kwegrid. Panguva yekudzima, sisitimu inogona kuramba ichipa michina yekuchaja yeAC kwemaawa angangoita mashanu kusvika masere, zvichiita kuti mabasa ekuchaja arambe achishanda.

3.4 Kudzikira kweZvivakwa uye Mari Yekushanda

Mhinduro iyi inodzivirira mari yakawanda uye nguva yakareba yekushandisa inobatanidzwa nekuvandudza transformer yemagetsi. Kuzvishandisa kwezuva, rutsigiro rwemagetsi akawandisa, uye kuchengetedza simba zvinobatsirawo kuderedza mari yemagetsi yenguva refu uye yekushandisa kwechiteshi.
