1. project Txheej txheem cej luam

Qhov project no muaj xws li kev siv lub AC-coupled photovoltaic-storage integrated system ntawm tus neeg siv khoom lub khw muag khoom 4S hauv Cambodia. Nws muaj lub 125kW photovoltaic inverter thiab lub energy storage system tshiab, uas ua rau muaj ob txoj haujlwm: 'self-generation for self-consuming with surplus feed-in to the grid' thiab 'off-grid backup power'. Tus qauv tsim ntawm lub system no suav nrog tus neeg siv khoom cov qauv siv hluav taws xob (kev siv nruab nrab txhua hnub yog kwv yees li 14.8kWh, sijhawm ua haujlwm 8:00–20:00) thiab txhawb kev muag hluav taws xob ntxiv txog li 15kWh rau lub grid txhua hnub.

2. Cov Hauj Lwm Qhia

Daim ntawv thov

Lub kaw lus ua haujlwm hauv ob hom:

Grid-connected hom:

- Cov khoom siv thaum nruab hnub muab qhov tseem ceeb rau lub zog photovoltaic;

- Kev tsim hluav taws xob PV ntau dhau them cov roj teeb cia ua ntej;

– Thaum lub roj teeb them tag, lub zog PV seem yuav raug muag rau lub grid (kaw ntawm 15kWh/hnub);

Thaum hmo ntuj lossis huab cua tsaus ntuj, lub roj teeb tso tawm fais fab kom txog thaum SOC poob qis dua 10%, thaum ntawd lub kaw lus kaw thiab hloov mus rau qhov chaw muab hluav taws xob tseem ceeb;

Txwv tsis pub them cov roj teeb los ntawm cov hluav taws xob.

Hom Standby Tawm ntawm Grid:

Thaum lub sijhawm hluav taws xob tsis ua haujlwm, lub kaw lus khaws cia hluav taws xob yuav hloov mus rau kev ua haujlwm tawm ntawm lub network kom muab cov khoom tseem ceeb;

Lub kaw lus yuav kaw thaum lub roj teeb tso tawm mus txog SOC < 10%, ua rau lub nra hnyav tsis txuas nrog.

Nruab Muaj Peev Xwm

Sab photovoltaic: 125kW inverter

Sab cia hluav taws xob: 100kW / 215kWh

Cov khoom siv txhawb nqa: 1 x 200kVA static transfer switch (STS)

Cov Khoom Siv Tseem Ceeb

Photovoltaic inverter

Lub tshuab hloov hluav taws xob (PCS)

Kev hloov pauv hloov pauv (STS)

Battery Management System (BMS)

Cua txias

Cov cuab yeej ntsuas ntsuas

Kev Sib Txuas Lus Sib Txuas Lus: RS485 Tseg (PV Inverter & Grid Connection Meter)

3. Qhov zoo ntawm qhov project

Kev Txhim Kho Kev Lag Luam: Ua kom muaj peev xwm tsim hluav taws xob thiab siv hluav taws xob ntau tshaj plaws kom txo tau kev siv hluav taws xob; txhawb nqa kev pub hluav taws xob ntau dhau txhua hnub kom tau nyiaj ntxiv.

Kev Ruaj Ntseg Zog: Muab lub zog thaub qab tawm ntawm lub network thaum lub sijhawm hluav taws xob tsis ua haujlwm, ua kom ntseeg tau tias kev ua haujlwm luv luv ntawm cov khoom tseem ceeb.

Kev Teem Sij Hawm Ntsig: Hloov pauv cov tswv yim them/tso tawm raws li SOC thresholds (10%–100%) kom ntev lub neej ntawm lub roj teeb.

Kev Sib Txuas Lus Zoo: Cov kev sib txuas lus txheem tshwj tseg ua rau kev sib koom ua ke nrog cov kab ke PV uas twb muaj lawm thiab cov khoom siv ntsuas hluav taws xob.

Kev Hloov Kho Hauv Zos: Kev tswj hwm kev cai tsim kho kom haum rau cov neeg siv khoom siv hluav taws xob tsawg tsawg txhua hnub (kwv yees li 14.8kWh) thiab cov sijhawm ua haujlwm, tiv thaiv kev muab khoom ntau dhau.
