Ukuthandwa kwemakethe ye-solar photovoltaic kuye kwaqhuba ukuthuthukiswa kwe-solari-inverterimboni.Ngokuvamile, ama-solar inverter ahlukaniswe abe izinhlobo ezintathu: ama-inverter aphakathi nendawo, ama-inverter ezintambo, nama-inverter amancane.
Ama-inverter amaphakathi, ahlangana kuqala bese eshintsha, afaneleka kakhulu izitshalo zamandla ezimaphakathi nendawo ezinokukhanya okufanayo.Ngenxa yezindleko zayo eziphansi, isetshenziswa kakhulu eziteshini zamandla kagesi ze-photovoltaic ezinkulu ezimaphakathi njengezimboni ezinkulu ezinokukhanya kwelanga okufanayo kanye neziteshi zikagesi zasogwadule.
Ama-inverter ezintambo asetshenziselwa ukuguqula abese eguquguquka, ikakhulukazi ophahleni abancane naphakathi nendawo, izitshalo ezincane zamandla aphansi, nezinye izimo.Izimo zokufaka izicelo zihluke kakhulu, futhi zingasetshenziswa ezinhlotsheni ezahlukene zeziteshi zikagesi, njengeziteshi zikagesi ezimaphakathi, iziteshi zikagesi ezisabalalisiwe, kanye neziteshi zikagesi eziphezu kophahla, ngentengo ephakeme kancane kuneziteshi zikagesi ezimaphakathi nendawo.
Ama-Micro inverters aguqulwa ngokuqondile futhi axhunywe kugridi, ikakhulukazi afanele izimo zasendlini nezincane ezisabalalisiwe.Ngokuvamile, amandla angaphansi kuka-1kw, ikakhulukazi eziteshini zamandla zasendlini ezisabalalisiwe nezincane ezisabalalisiwe ezisophahleni lwezimboni nezohwebo, kodwa intengo iphezulu, futhi kunzima ukuyinakekela uma kwenzeka yehluleka.
Ubuholi obubiza kancane
Iimboni ye-nverterngaphambi kuka-2010 wayengeyena owaseShayina.Njengemakethe ye-photovoltaic ebaluleke kakhulu, i-Europe ibala ngaphezu kwe-60% yomthamo omusha we-photovoltaic ofakwe emhlabeni wonke unyaka ngamunye phakathi kuka-2004 no-2011. Njengamandla amakhulu kagesi, i-SMA, i-photovoltaic giant, yaqala ukuthuthukisa ama-photovoltaic inverters ngo-1987, futhi yethula I-inverter yokuqala yochungechunge lwezentengiselwano kanye ne-inverter emaphakathi, ehola imboni ngokuthembela ezinzuzweni zobuchwepheshe.
Imakethe yomhlaba wonke icishe iphathwe yizinkampani zaseYurophu, futhi phakathi kwe-10 ephezulu yokuthunyelwa kwe-photovoltaic inverter, ngaphandle kwezinkampani ezintathu zaseNyakatho Melika, ezinye zivela eYurophu.Izinkampani ezinhlanu zase-Europe, i-SMA, i-KACO, i-Fronius, i-Ingeteam, ne-Siemens kuphela, yenza u-70% wesabelo semakethe.Isabelo semakethe sezinkampani ze-SMA sesifinyelele ku-44%, okulingana nengxenye yemakethe ye-photovoltaic inverter.
Ngesikhathi lapho ukuthuthukiswa kwe-photovoltaic kuqhubeka ngokugcwele eYurophu, intuthuko ye-photovoltaic yaseChina isencane: ukuntuleka kocwaningo lwezobuchwepheshe kanye nempumelelo yentuthuko kuye kwaba yisici esikhulu esivimbela ukuthuthukiswa.Njengoba sonke sazi, ama-inverters e-photovoltaic axhuma i-photovoltaic array kanye negridi yamandla, engaguqula amandla e-DC akhiqizwa yisistimu ibe amandla e-AC adingekayo empilweni ngokusebenzisa ubuchwepheshe bokuguqula amandla kagesi, futhi ingabizwa ngokuthi inhliziyo yalo lonke uhlelo lwe-photovoltaic.
“Njengengqondo” yezinhlelo zokuphehla amandla e-photovoltaic, ukukhiqizwa nokukhiqiza kwayo kuhlanganisa ubuchwepheshe bokuklama isistimu yamandla, ubuchwepheshe be-semiconductor, ubuchwepheshe bamandla kagesi, ubuchwepheshe be-microcomputer, ubuchwepheshe bokuhlela isoftware, njll. Embonini eyinkimbinkimbi kakhulu edinga izinga eliphezulu lobuchwepheshe. ukubambisana ukuqedela, ama-inverters afana nabaholi abahambisa ezinye izingxenye ngobuchopho babo, futhi ukunyakaza kwabo konke kuzothinta ngokuqondile umkhuba jikelele wezinhlelo ze-photovoltaic.
Ukuguqulwa kwayo kahle nokuthembeka kube yizinkomba eziyinhloko zokwahlulela ukusebenza kwe-inverter.Uma nje amandla eba phezulu, angasho ukulahlekelwa okuphansi, okungenye yempumelelo ebalulekile ekunciphiseni izindleko zikagesi ngehora le-kilowatt ngamaphrojekthi we-photovoltaic.NgoZibandlela wezi-2003, i-Sungrow Power yethula igridi yokuqala yaseShayina engu-10kW photovoltaic exhunywe isiguquli esinamandla esinamalungelo empahla yengqondo ezimele, okwenza igxathu elibalulekile eliya phambili ekuguquleni ngendlela esebenza kahle futhi ngaleyo ndlela kwephule ukubusa kwamanye amazwe.
Ukuhlanganiswa kwesitoreji esibonakalayo kuwumkhuba ongenakugwemeka
Isiguquli se-photovoltaic esijwayelekile esixhunywe kugridi singakwazi ukwenza ukuguqulwa kwendlela eyodwa kuphela ukusuka ku-DC kuya kumandla we-AC, futhi sikhiqiza ugesi kuphela emini.Amandla akhiqizwayo angaphinde athinteke isimo sezulu, esinezinkinga ezingalindelekile.Kodwa-ke, i-inverter yokugcina amandla ihlanganisa imisebenzi yeziteshi zamandla ezixhunywe kugridi ye-photovoltaic kanye neziteshi zamandla zokugcina amandla, ukugcina amandla kagesi uma eningi, futhi iguqule amandla kagesi agciniwe lapho enganele ukuwakhipha kugridi, ukulinganisa amandla umehluko wokusetshenziswa phakathi kwemini nobusuku nezinkathi ezahlukene zonyaka, Idlala indima ekushebeni okuphezulu nokugcwaliswa kwesigodi.
I-inverter yokugcina amandla kanye ne-inverter exhunyiwe yegridi inobuchwepheshe obufanayo.Yize isekethe yokuvikela kanye nesekhethi ye-buffer ihlukile, inkundla yehadiwe kanye nesakhiwo se-topology kuyafana, ngakho indlela yokunciphisa izindleko ngokuyisisekelo ihambisana ne-photovoltaic.i-inverter.
Esikhathini esifushane, isidingo sokugcinwa kwamandla nokufakwa ikakhulukazi siqhutshwa uhlangothi lwenqubomgomo, futhi luthintwa yizingqinamba endaweni yokumuncwa kanye nokuguquguquka kukagesi, ohulumeni abahlukahlukene baye basheshisa ukwethulwa kochungechunge lwezinqubomgomo ezifanele ukukhuthaza imakethe yokugcina amandla. .Ezinye izifundazwe namadolobha aseShayina aze agunyaza ukwabiwa nokugcinwa kwamandla amasha.
Ngokuhamba kwesikhathi, ukuhlanganiswa kwe-optical kanye nesitoreji kuwumkhuba ongenakugwemeka, futhi izinqubomgomo kufanele zikhuthaze kuqala ukwabiwa nokugcinwa kwamandla amasha.Ngokombono, esimweni lapho amandla e-photovoltaic enikezwa ngokuphelele, kuyadingeka ukulungiselela isitoreji samandla esingu-1:3 kuya ku-1:5 ukuze kuzuzwe ukunikezwa kwamandla okungaphazanyiswa.Ukuhlanganiswa kwe-Optical storage kulindeleke ukuthi kube yisixazululo samandla ahlanzekile esizayo.
