Ichi chinyorwa chinopa kambani yedu yakagadziridzwa 250kW-1050kWh Grid-yakabatana Energy Storage System (ESS).Muitiro wacho wose, kusanganisira kugadzira, kuisa, kugadza, uye kushanda kwamazuva ose, kwakatora mwedzi mitanhatu yose.Chinangwa chechirongwa ichi ndechekuita peak shaving uye nzira dzekuzadza mipata kuderedza mutengo wemagetsi.Pamusoro pezvo, chero magetsi akawandisa anogadzirwa anotengeswa kugedhi, zvichiunza imwe mari.Mutengi akaratidza kugutsikana kukuru nemhinduro yechigadzirwa nemasevhisi edu.
Yedu Grid-yakabatana ESS System ndiyo yakarongedzwa mhinduro inopa yakavimbika uye inoshanda simba rekuchengetedza masimba.Inopa kubatanidzwa kusina musono negridi, ichibvumira kwakaringana kurodha manejimendi uye mashandisirwo emhando yepamusoro-mupata wemisiyano yemitengo senge regidhi redunhu remitengo.
Iyo sisitimu ine zvinhu zvakasiyana siyana, zvinosanganisira lithium iron phosphate mabhatiri, bhatiri manejimendi masisitimu, simba rekuchengetedza bidirectional inverters, gasi moto kudzvinyirira masisitimu, uye nharaunda kutonga masisitimu.Aya ma subsystems akabatanidzwa zvine hungwaru mukati meiyo yakamisikidzwa yekutakura mudziyo, ichiita kuti ive yakasiyana-siyana uye yakakodzera kune dzakasiyana siyana dzekushandisa.
Mamwe mabhenefiti akakosha eGridhi-yakabatana ESS System anosanganisira:
● Yakananga grid interconnection, kufambisa mhinduro ine simba kune simba rekutakura kuchinja uye kusiyana kwemutengo wemusika.
● Kuvandudza hupfumi hwehupfumi, zvichiita kuti kugadzirwa kwemari kwakagadziridzwa uye nguva dzekubhadhara mari.
● Kutsvaga kukanganisa kunoshanda uye nzira dzekukurumidza kupindura kuitira kuchengetedza kushanda kwenguva refu.
● Modular dhizaini inobvumira scalable kuwedzera kwemabhatiri mayuniti uye simba rekuchengetedza bidirectional inverters.
● Real-time kuverenga kwekushandiswa kwemagetsi uye kugadzirisa mari maererano nematunhu grid pricing policy.
● Injiniya yakarongeka yekuisa maitiro, zvichiita kuti kuderedza kushanda uye kugadzirisa mari.
● Yakanakira kudzora mutoro kuderedza mari yemagetsi ebhizinesi.
● Inokodzera kurongeka kwegridi uye kugadzikana kwemitoro yekugadzira.
Mukupedzisa, yedu Grid-yakabatana ESS System ndeye yakavimbika uye inoshanda zvakasiyana mhinduro yakagamuchira kurumbidzwa kukuru kubva kune vatengi vedu vanogutsikana.Dhizaini yayo yakazara, kusanganisa isina musono, uye kushanda kwakanaka kunoita kuti ive chinhu chakakosha kune akasiyana maindasitiri uye maapplication.

Nhanganyaya kune Kudzora kweContainer Energy Storage System
3.1 Running state
Iyi sisitimu yekuchengetedza simba inoisa mashandiro ebhatiri mumatunhu matanhatu akasiyana: kuchaja, kuburitsa, kugadzirira static, kukanganisa, kugadzirisa, uye DC otomatiki grid yekubatanidza nyika.
3.2 Kuchaja uye kuburitsa
Iyi sisitimu yekuchengetedza simba inokwanisa kugashira nzira dzekutumira kubva papuratifomu yepakati, uye aya mazano anobva abatanidzwa uye akaiswa mukati meiyo dispatch control terminal.Mukushaikwa kwechero nzira nyowani dzekutumira dziri kugamuchirwa, sisitimu inotevedzera yazvino zano rekutanga kuchaja kana kuburitsa mashandiro.
3.3 Yakagadzirira kusaita basa
Kana iyo simba rekuchengetedza sisitimu yapinda munzvimbo yakagadzirira isina basa, iyo simba bidirectional kuyerera controller uye bhatiri manejimendi system inogona kusetwa kune yekumira mode kuderedza mashandisiro emagetsi.
3.4 Bhatiri rakabatana kune grid
Iyi simba rekuchengetedza sisitimu inopa yakazara DC grid yekubatanidza logic kutonga kushanda.Kana paine musiyano wevoltage unopfuura kukosha kweseti mukati mebhatiri paki, inodzivirira yakananga grid yekubatanidza yenhevedzano bhatiri paki ine yakawandisa voltage musiyano nekuvhara anowirirana maconta.Vashandisi vanogona kupinda iyo otomatiki DC grid yekubatanidza mamiriro nekuitanga, uye sisitimu inozopedzisa kubatanidza grid yeese akateedzana mabhatiri mapaketi ane akakodzera voltage anofananidzwa, pasina kudiwa kwekupindira kwemaoko.
3.5 Emergency shutdown
Iyi sisitimu yekuchengetera simba inotsigira manyorerwo ekumisikidza kuvharika, uye nechisimba kudzima mashandiro ehurongwa nekubata chiratidzo chekudzima chiri kure nemhete yeko.
3.6 Rwendo rwakafashukira
Kana iyo simba rekuchengetedza sisitimu yaona kukanganisa kwakakomba, inozodzima otomatiki iyo inotyora wedunhu mukati mePCS uye yoparadzanisa gidhi remagetsi.Kana muparadzi wedunhu aramba kushanda, sisitimu inoburitsa chiratidzo chekufashukira rwendo kuti iite yekumusoro redunhu breaker rwendo uye kuparadzanisa kukanganisa.
3.7 Kudzima gasi
Iyo simba rekuchengetedza sisitimu ichatanga iyo heptafluoropropane yekudzima moto system kana tembiricha yadarika kukosha kwealarm.
