Inotungamirwa ne "double kabhoni" zvinangwa (carbon peaking uye kabhoni kusarerekera), yeChina photovoltaic indasitiri iri kusangana nekuchinja kusati kwamboitika uye kusvetuka.Muchikamu chekutanga cha2024, China itsva photovoltaic power generation grid-yakabatana simba yakasvika 45.74 miriyoni kilowatts, uye cumulative grid-yakabatana simba rakapfuura 659.5 miriyoni kilowatts, zvichiratidza kuti photovoltaic indasitiri yapinda padanho idzva rebudiriro.Nhasi, tichaongorora zvakadzama kuumbwa uye kupatsanurwa kwegridi-yakabatana photovoltaic magetsi ekugadzira masisitimu.Kunyangwe iri "kuzvishandisa wega kweyakagoverwa photovoltaic uye grid-yakabatana yakawedzera simba", kana iyoyakakura-yakakura grid yekubatanidzaye centralized photovoltaic.Iwe unogona kuzvireva zvichibva pane zvinyorwa zvemukati.
Classification yegrid-yakabatanaphotovoltaic simba rekugadzira masisitimu
Grid-yakabatana photovoltaic magetsi ekugadzira masisitimu anogona kupatsanurwa kuita countercurrent grid-yakabatana masisitimu, asiri-anopokana grid-akabatana masisitimu, switching grid-yakabatana masisitimu, DC uye AC gidhi-yakabatana masisitimu, uye yedunhu gidhi-yakabatana masisitimu zvichienderana nekuti iwo magetsi. simba rinotumirwa kune simba system.
1. Countercurrent grid-yakabatana simba rekugadzira system
Apo simba rinogadzirwa ne solar photovoltaic power generation system rinokwana, simba rinosara rinogona kutumirwa kune grid yeruzhinji;apo simba rinopiwa ne solar photovoltaic power generation system harina kukwana, magetsi emagetsi anopa simba kumutoro.Sezvo simba rinopihwa kune grid mune yakatarisana negedhi, inonzi countercurrent photovoltaic simba rekugadzira system.
2. Grid-yakabatana simba rekugadzira system pasina countercurrent
Kunyange kana solar photovoltaic power generation system inogadzira simba rakakwana, haipe simba kune grid yeruzhinji.Zvisinei, kana solar photovoltaic power generation system inopa simba risina kukwana, ichave inoshandiswa nemagetsi evanhu vose.
3. Kushandura grid-yakabatana simba rekugadzira hurongwa
Iyo switching grid-yakabatana simba rekugadzira system ine basa re otomatiki maviri-nzira switching.Kutanga, apo photovoltaic simba rekugadzira hurongwa hunoita simba risina kukwana nekuda kwemamiriro ekunze, kuchena kwekushayikwa, nezvimwewo, kushandura kunogona kushandura kudivi rekupa simba regridhi, uye girasi remagetsi rinopa simba kumutoro;chechipiri, apo girasi remagetsi rinongoerekana rarasikirwa nesimba nokuda kwechimwe chikonzero, iyo photovoltaic simba rekugadzira hurongwa Inogona kushandura yega kuti iparadzanise girasi remagetsi kubva kune photovoltaic power generation system uye kuva yakazvimirira photovoltaic power generation system.Kazhinji, kushandura grid-yakabatana photovoltaic magetsi ekugadzira masisitimu ane midziyo yekuchengetedza simba.
4. Giridhi yekuchengetedza magetsi-yakabatana simba rekugadzira hurongwa
Iyo grid-yakabatana photovoltaic simba rekugadzira system ine simba rekuchengetedza mudziyo ndeyekugadzirisa simba rekuchengetedza mudziyo zvinoenderana nezvinodiwa mumhando dzataurwa pamusoro apa dzegridhi-yakabatana photovoltaic magetsi ekugadzira masisitimu.Photovoltaic masisitimu ane masimba ekuchengetedza emagetsi anoshanda zvakanyanya uye anogona kushanda akazvimirira uye kupa simba kumutoro kazhinji kana paine kupera kwemagetsi, muganhu wemagetsi kana kukundikana mugedhi remagetsi.Naizvozvo, iyo grid-yakabatana photovoltaic simba rekugadzira system ine simba rekuchengetedza mudziyo inogona kushandiswa semagetsi emagetsi enzvimbo dzakakosha kana mitoro yekukurumidzira senge yekukurumidzira yekutaurirana magetsi, zvekurapa, zviteshi zvegasi, evacuation site chiratidzo uye mwenje.
5. Yakakura-yakabatana grid-yakabatana simba rekugadzira system
Iyo yakakura-yakakura grid-yakabatana photovoltaic simba rekugadzira system inoumbwa akati wandei grid-yakabatana photovoltaic magetsi ekugadzira zvikamu.Imwe neimwe photovoltaic magetsi yekugadzira unit inoshandura iyo DC simba rinogadzirwa nesolar cell array kuita 380V AC simba kuburikidza neiyo photovoltaic grid-yakabatana inverter, uye yozoishandura kuita 10KV AC high-voltage simba kuburikidza neiyo booster system.Inobva yatumirwa kune 35KV transformer system uye yakabatanidzwa mu35KV AC simba.Mugetsi remagetsi epamusoro-voltage, iyo 35KV AC yakakwira-voltage simba inoshandurwa kuita 380 ~ 400V AC simba kuburikidza nenhanho-pasi sisitimu semagetsi ekuchengetedza magetsi echiteshi chemagetsi.
6. Kugoverwa kwemagetsi hurongwa
Distributed photovoltaic power generation system, inozivikanwawo seyakagoverwa simba rekugadzira kana kugovera simba rekupa, inoreva kumisikidzwa kwediki mafotovoltaic magetsi ekupa masisitimu panzvimbo yemushandisi kana padhuze nesaiti yekushandisa simba kuti isangane nezvinodiwa zvevashandisi chaivo uye kutsigira hupfumi hwe iyo iripo yekugovera network.oparesheni, kana zvose.
7. Intelligent microgrid system
Microgrid inoreva diki diki kugadzirwa kwemagetsi uye yekugovera sisitimu inoumbwa neakagoverwa magetsi masosi, magetsi ekuchengetedza magetsi, magetsi ekushandura magetsi, ane hukama mitoro, yekutarisa uye yekudzivirira zvishandiso.Ihurongwa hunokwanisa kuona kuzvidzora, kudzivirira nekudzivirira.Iyo inotungamirwa inozvimiririra sisitimu inogona kushanda pamwe chete neyekunze gidhi remagetsi kana iri yega.Iyo microgrid yakabatana nedivi remushandisi uye ine hunhu hwemutengo wakaderera, yakaderera voltage uye yakaderera kusvibiswa.Iyo microgrid inogona kubatanidzwa kune yakakura magetsi grid, kana inogona kubviswa kubva kune huru grid uye inomhanya yakazvimiririra kana gidhi remagetsi ratadza kana kudiwa.
Kuumbwa kwegridi-yakabatana photovoltaic simba rekugadzira system
Iyo photovoltaic array inoshandura simba rezuva kuita DC simba, rinoisanganisa kuburikidza nebhokisi rekubatanidza, uye yozoshandura iyo DC simba kuita AC simba kuburikidza neinverter.Iyo voltage level ye photovoltaic power station yakabatana kune gidhi remagetsi inotarirwa maererano nehukuru hwe photovoltaic power station inotsanangurwa nekombiyuta yekubatanidza photovoltaic power station kune girasi remagetsi., mushure mokunge magetsi awedzerwa ne transformer, yakabatanidzwa kune grid power grid.
