1. Project Overview

Chirongwa ichi chinosanganisira kuiswa kwe AC-coupled photovoltaic-storage integrated system panzvimbo yemutengi we4S muCambodia. Inosanganisira 125kW photovoltaic inverter uye system itsva yekuchengetera simba, zvichiita kuti pave nemabasa maviri: 'kuzvigadzira wega wega nekushandisa zvakanyanya ku grid' uye 'off-grid backup power'. Dhizaini yesystem iyi inonyatso tarisa mashandisirwo emagetsi emutengi (avhareji yekushandiswa kwezuva nezuva kweinenge 14.8kWh, maawa ekushanda 8:00–20:00) uye inotsigira kutengeswa kwemagetsi anosvika 15kWh kugrid zuva nezuva.

2. Project Details

kunyoresa

Sisitimu inoshanda nenzira mbiri:

Grid-yakabatana modhi:

- Mitoro yemasikati inonyanya kukosha pakugadzira simba remagetsi rinoshandisa simba rezuva;

- Kugadzira PV yakawandisa kunotanga kuchaja mabhatiri ekuchengetera;

- Kana bhatiri razara, simba rePV rakawandisa rinogona kutengeswa kugrid (rakavharirwa pa15kWh/zuva);

Munguva yehusiku kana kuti madota, kuburitswa kwebhatiri kunopa simba kusvika SOC yadzikira pasi pe10%, panguva iyo sisitimu inodzima uye inochinja kuenda kune mains supply;

Kuchaja mabhatiri kubva kumagetsi makuru hakubvumirwi.

Maitiro Ekumira Asina Gridhi:

Kana magetsi akadzimwa, sisitimu yekuchengetera magetsi inochinja yega kuenda kukushanda kwekunze kwegridi kuti ipe mitoro yakakosha;

Sisitimu iyi inodzima kana bhatiri rasvika paSOC < 10%, zvichikonzera kuti mutoro udzimwe.

3. Projekti Yakanakira

Kuvandudza Hupfumi: Kunowedzera kuzvigadzira uye kushandisa magetsi kuti kuderedze kushandiswa kwemagetsi; kunotsigira kuwedzerwa kwemari zuva nezuva kuti uwane mari yakawanda.

Kuchengetedzwa Kwesimba: Inopa simba rekuchengetedza risingashande pamagetsi panguva yekudzima kwemagetsi, zvichiita kuti mutoro wakakosha ushande kwenguva pfupi.

Kuronga Kwakangwara: Inochinja otomatiki nzira dzekuchaja/kuburitsa simba zvichibva pamiganho yeSOC (10%–100%) kuti iwedzere hupenyu hwebhatiri.

Kushanda Kwazvo: Nzvimbo dzekutaurirana dzakachengetwa dzinobatsira kubatanidzwa nemaitiro ePV aripo uye michina yekuyera grid.

Kugadziriswa Kwenzvimbo: Pfungwa dzekutonga dzakagadzirwa dzakagadzirirwa kushandiswa kwakaderera kwezuva nezuva kwevatengi (inenge 14.8kWh) uye maawa ekushanda, zvichidzivirira kubhadharwa kwakawandisa.
