Tekinoroji yekuchengetedza simba inobatsira mapurojekiti e photovoltaic (PV) kuderedza kuderedzwa kwemagetsi uye inoita kuti grid isanganiswe nema PV systems akawanda. Pakati pematekinoroji ekuchengetedza simba aripo iye zvino uye ari kutengeswa, kuchengetedza simba remagetsi kwakakodzera kubatanidzwa nemapurojekiti ePV nekuda kwezvakanaka zvayo zvekusakanganiswa nemamiriro ekunze, kukurumidza kupindura, uye hupenyu hwenguva refu.
I. Sisitimu yePhotovoltaic
Kugadzira simba remagetsi rezuva, iro rinozivikanwawo sekugadzira simba remagetsi rezuva, itekinoroji inoshandura simba rechiedza kuita simba remagetsi ichishandisa simba remagetsi remagetsi panzvimbo ye semiconductor interface. Inonyanya kuumbwa nezvikamu zvitatu: ma solar panels (PV modules), ma controllers, uye ma inverters.
Zviteshi zvemagetsi zve photovoltaic zvinogona kukamurwa kuita zvikamu zviviri zvichienderana nekurongeka kwezvikamu: zviteshi zvemagetsi zve PV zviri pakati nepakati uye zviteshi zvemagetsi zve PV zvakaparadzirwa.
Nzvimbo dzeMagetsi dzePV dzakakura: Idzi inzvimbo dzemagetsi dzePV dzakakura dzakavakwa munzvimbo dzakakura dzakadai semarenje, magetsi anogadzirwa akabatanidzwa zvakananga mugridi yeruzhinji uye akabatana nesystem yekutumira magetsi ine simba guru kuti ipe mitoro iri kure. Dzinowanzo kuwanikwa munzvimbo dzakadai seQinghai, Ningxia, Gansu, neXinjiang.
Zviteshi zveMagetsi zvePV Zvakaparadzirwa: Izvi zvinovakwa uye zvinofambiswa panzvimbo yemushandisi kana pedyo, kunyanya kuti zvishandiswe zvega nemagetsi akawandisa anoiswa mugrid. Zvinowanzo shandisa matenga edzimba, nzvimbo dzekupaka mota, nedzimwe nzvimbo dzakapararira kuvaka zviteshi zvemagetsi zvePV uye zvakajairika kuSouth neNorth China. Kugadzirwa kwePV yakaparadzirwa kwakambosangana nematambudziko nekuda kwekuverengerwa mukutarisira zviyero. Zvisinei, yakava nyaya inopisa muindasitiri nekuda kwemutemo we "dunhu rese rakagoverwa pilot".
II. Nzira dzekubatanidza masisitimu ekuchengetera simba
Zviteshi zvemagetsi zvePV zvinogona kushandisa nzira mbiri dzehunyanzvi: kubatanidzwa kweAC-side centralized uye kubatanidzwa kweDC-side distributed.
Kubatanidzwa kweCentralized kudivi reAC:
Munzira iyi, bhatiri rekuchengetera simba rinoiswa pakati pechiteshi chemagetsi chinosimudzira simba/chinochinja simba. Simba reDC rinodzoserwa mberi uye rinowedzerwa simba risati rabatanidzwa nebhazi reAC rechiteshi chinosimudzira simba, nekuchinjana kwesimba pakati pesystem yekuchengetera simba nesystem yesimba kuchidzorwa ne dispatch. Nzira iyi inoda kugadzirisa maPCS akawanda (Power Conversion Systems) kuti ashande pamwe chete uye kuwedzera ma booster transformers nemidziyo yekugovera.
Kubatanidzwa Kwakaparadzirwa kweDC:
Nzira iyi inogovera mayuniti ekuchengetera simba mumaPV sub-array akasiyana-siyana, imwe neimwe ine mudziyo wayo wekuchengetera simba, kunyanya inosanganisira PV inverter, booster transformer, DC/DC module, uye bhatiri rekuchengetera. Muchirongwa ichi chekuchengetera simba chakagoverwa, kutaurirana pakati peDC/DC module nePV inverter kunogona kupfavisa simba rinobuda, asi haigone kuchengetedza simba rakawanda kudivi reAC. Kuti simba rifambe zvakanaka, PV inverter inofanira kutsiviwa nePCS yedivi rimwe chete.
Kune zviteshi zvemagetsi zvePV zviripo, nzira yekubatanidza yakagoverwa neDC inosangana nematambudziko nekuda kwenzvimbo shoma yekuisa michina uye kugadziriswa kwakakosha kwewaya dzemagetsi, zvinoda kudzimwa kwemagetsi kwenguva refu kuti zvigadzirwe patsva, nokudaro zvichikonzera mari yakawanda.
Kushandisa masisitimu ekuchengetera simba remagetsi nemakemikoro kumapurojekiti ePV kunoita kuti simba remagetsi rakachena rishande zvakanaka uye zvakanaka, zvichizadzisa zvinodiwa nemakambani emagetsi. Izvi zvinogadzirisawo nyaya yekuderedzwa kwechiedza uye kuderedza kutambisa zviwanikwa.
