Mhinduro yedu yakabatanidzwa ye photovoltaic, yekuchengetedza simba, uye system yekuchaja inoedza kugadzirisa zvine hungwaru kunetseka kwemotokari dzemagetsi nekubatanidzamapombi ekuchaja eV, photovoltaics, uye matekinoroji ekuchengetedza simba remabhatiri. Inokurudzira kufamba kwemotokari dzemagetsi nenzira yakasarudzika kuburikidza nesimba idzva re photovoltaic, ukuwo ichitsigira kuchengetedza simba ichideredza kumanikidzwa kwegrid kunokonzerwa nemitoro inorema. Inopedzisa cheni yeindasitiri yemabhatiri kuburikidza nekushandiswa kwakarongeka, ichivimbisa kukura kwakanaka kweindasitiri. Kuvakwa kweiyi sisitimu yesimba yakabatana kunokurudzira kuiswa kwemagetsi uye kukura kwakangwara kweindasitiri, zvichiita kuti simba rakachena, senge simba rezuva, rive simba remagetsi kuburikidza ne photovoltaics uye kurichengeta mumabhatiri. Mirwi yekuchaja mota dzemagetsi inobva yatamisa simba iri remagetsi kubva kumabhatiri kuenda kumotokari dzemagetsi, zvichigadzirisa dambudziko rekuchaja.
I. Topology yeSisitimu yeMagiradhi eKuchaja yePhotovoltaic-Storage-Charging
Sezvakaratidzwa mudhayagiramu iri pamusoro apa, michina mikuru ye integrated photovoltaic, energy storage, uye charging microgrid system topology inotsanangurwa pazasi:
1. Chinoshandura simba rekuchengetedza magetsi chiri kunze kwegrid: Rutivi rweAC rwechinoshandura simba re250kW rwakabatana zvakafanana nebhazi re380V AC, uye rutivi rweDC rwakabatana zvakafanana nechina chinoshandura simba re50kW divi rimwe chete, zvichiita kuti simba rifambe nenzira mbiri, kureva kuti, kuchaja nekuburitsa simba rebhatiri.
2. Maconverter eDC/DC anotungamira divi rimwe chete: Rutivi rwemagetsi ane simba re50kW DC/DC rwakabatana neDC terminal yeconverter, uye divi rine simba remagetsi rakabatana nepower battery pack. DC/DC converter yega yega yakabatana nebattery pack imwe chete.
3. Sisitimu yemagetsi yebhatiri: Masero gumi nematanhatu e3.6V/100Ah (1P16S) anoumba module imwe chete yebhatiri (57.6V/100Ah, huwandu hwepamusoro hwe5.76KWh). Mamodule gumi nemaviri emabhatiri akabatanidzwa muzvikamu zvakatevedzana kuti agadzire boka remabhatiri (691.2V/100Ah, huwandu hwepamusoro hwe69.12KWh). Bateri cluster yakabatana ne low-voltage terminal ye bidirectional DC/DC converter. Sisitimu yebhatiri ine ma bhatiri mana ane huwandu hwepamusoro hwe276.48 kWh.
4. MPPT Module: Rutivi rweMPPT module rwakabatana nebhazi re750V DC, nepo divi revoltage rakabatana nephotovoltaic array. Photovoltaic array ine tambo nhanhatu, imwe neimwe ine mamodule 18 275Wp akabatana akatevedzana, e108 photovoltaic modules uye simba rese rinobuda re29.7 kWp.
5. Nzvimbo dzekuchaja: Sisitimu iyi ine matatu ane simba re60kWnzvimbo dzekuchaja dzeDC eV(huwandu nesimba renzvimbo dzekuchaja zvinogona kugadziriswa zvichienderana nekufamba kwemotokari uye kudiwa kwesimba rezuva nezuva). Rutivi rweAC rwenzvimbo dzekuchaja rwakabatana nebhazi reAC uye runogona kushandiswa ne photovoltaics, kuchengetedza simba, uye grid.
6. EMS & MGCC: Masisitimu aya anoita mabasa akadai sekuchaja nekuburitsa simba remagetsi uye kutarisa ruzivo rweSOC yemabhatiri zvichienderana nemirairo kubva kunzvimbo yepamusoro yekutumirwa kwemagetsi.
II. Hunhu hweSisitimu yeSimba reKuchaja rePhotovoltaic-Storage-Charging
1. Sisitimu iyi inoshandisa dhizaini yekudzora ine mativi matatu: denga repamusoro ndiyo sisitimu yekutonga simba, denga repakati ndiyo sisitimu yekudzora yepakati, uye denga repasi ndiyo danda remidziyo. Sisitimu iyi inobatanidza zvishandiso zvekushandura huwandu, zvishandiso zvine chekuita nekutarisa mutoro uye kudzivirira, zvichiita kuti ive sisitimu inozvitonga inokwanisa kuzvidzora, kudzivirira, uye kutonga.
2. Maitiro ekutumira simba remagetsi ehurongwa hwekuchengetedza simba anogadziriswa/akagadziriswa zvichienderana nemitengo yemagetsi yepamusoro-soro, mupata, uye yakatsetseka yegridi yemagetsi uye SOC (kana voltage yekupedzisira) yemabhatiri ekuchengetedza simba. Sisitimu iyi inogamuchira kutumira kubva kuhurongwa hwekutarisira simba (EMS) kuti ikwanise kuchaja nekuburitsa simba.
3. Sisitimu iyi ine mabasa akazara ekutaurirana, kutarisa, kutarisira, kudzora, yambiro yekutanga, uye kudzivirira, ichivimbisa kushanda kwakachengeteka kwenguva refu. Mamiriro ekushanda kwesisitimu anogona kutariswa kuburikidza nekombuta, uye ine kugona kwakakura kwekuongorora data.
4. Sisitimu yekutarisira mabhatiri (BMS) inotaurirana nesisitimu yekutarisira simba (EMS), ichiisa ruzivo rwemabheteri, uye, pamwe chete neEMS nePCS, inoita mabasa ekutarisa nekudzivirira mabhatiri.
Purojekiti iyi inoshandisa PCS inoshandura simba rekuchengetera magetsi, iyo inobatanidza zvishandiso zvekuchinja zviri pagrid nezviri kunze kwegrid uye makabati ekuparadzira. Ine basa rekuchinja pakati pegrid neiri kunze kwegrid mumasekondi asina kujeka, inotsigira nzira mbiri dzekuchaja: simba remagetsi risingaperi riri pagrid uye simba risingaperi, uye inogamuchira kuronga nguva chaiyo kubva pakombuta inochengeta.
III. Kudzora neKutarisira kweSisitimu Yekuchengetera neKuchaja yePhotovoltaic
Kudzora sisitimu kunoshandisa dhizaini ine nhanho nhatu: EMS ndiyo layer yepamusoro yekuronga nguva, system controller ndiyo layer yepakati yekubatanidza, uye DC-DC nemapombi ekuchaja ndiwo layer yemidziyo.
EMS nesystem controller zvinhu zvakakosha, zvinoshanda pamwe chete kuti zvitarisire uye kuronga hurongwa hwe photovoltaic-storage-charging system:
1. Mabasa eEMS
1) Maitiro ekudzora kutumirwa kwesimba anogona kugadziriswa zviri nyore uye nzira dzekuchaja nekubvisa simba rekuchengetedza simba pamwe nemirairo yesimba zvinogona kuiswa zvichienderana nemitengo yemagetsi yenguva yegrid yenzvimbo.
2) EMS inoita telemetry chaiyo uye kutarisa kuchengetedzwa kwezvishandiso zvikuru zviri mukati mesystem, kusanganisira asi kwete kungogumira kuPCS, BMS, photovoltaic inverters, uye mapombi ekuchaja, uye inotarisira zviitiko zvekuvhundutsa zvakataurwa nemidziyo uye kuchengetwa kwedata rekare nenzira yakabatana.
3) EMS inogona kuisa data rekufanotaura kwesystem uye mhedzisiro yekuongorora kuverenga kunzvimbo yepamusoro yekutumirwa kwemagetsi kana sevha yekutaurirana iri kure kuburikidza neEthernet kana 4G communication, uye kugamuchira mirairo yekutumira panguva chaiyo, ichipindura kumutemo weAGC frequency, peak shaving, uye kumwe kutumira kuti kugutse zvinodiwa nesystem yemagetsi.
4) EMS inowana hukama nehurongwa hwekutarisa zvakatipoteredza nekudzivirira moto: kuona kuti michina yese yadzimwa moto usati watanga, kupa maalarm nemaalarm anonzwika uye anoonekwa, uye kuisa zviitiko zvealarms kumashure.
2. Mabasa eMutongi weSisitimu:
1) Mutongi wehurongwa anogamuchira nzira dzekuronga kubva kuEMS: nzira dzekuchaja/kuburitsa magetsi uye mirairo yekuronga magetsi. Zvichienderana nekugona kweSOC kwebhatiri rekuchengetera simba, mamiriro ekuchaja/kuburitsa magetsi ebhatiri, kugadzira simba remagetsi, uye kushandiswa kwemurwi wekuchaja, inogadzirisa manejimendi ebhazi nenzira inochinjika. Nekutarisira kuchaja nekuburitsa magetsi eDC-DC converter, inoita kuti bhatiri rekuchengetera simba ridzorwe nekuchaja, zvichiita kuti pave nekugona kushandisa simba rekuchengetedza magetsi zvakanyanya.
2) Kusanganisa DC-DC charge/discharge mode uyemurwi wekuchaja mota yemagetsiKana ichichaja, inofanira kugadzirisa muganho wesimba re inverter ye photovoltaic uye kugadzira simba re PV module. Inofanirawo kugadzirisa maitiro ekushanda kwe PV module uye kutonga system bus.
3. Mabasa eMidziyo - DC-DC:
1) Chishandiso chemagetsi, chinoita kuti pave nekushandurwa pakati pesimba rezuva nekuchengetedza simba remagetsi.
2) Chinoshandura DC-DC chinowana mamiriro eBMS uye, pamwe chete nemirairo yekuronga yesystem controller, chinoita DC cluster control kuti ive nechokwadi chekuti bhatiri rinogara riripo.
3) Inogona kuzvitonga, kudzora, uye kudzivirirwa zvichienderana nezvinangwa zvakatarwa.
