Chii chinonzi photovoltaic, chii chekuchengetedza simba, chii chinoshandura, chii inverter, chii chinonzi PCS uye mamwe mazwi makuru
01, Kuchengetera magetsi uye photovoltaic maindasitiri maviri
Ukama huri pakati pavo ndehwokuti photovoltaic system inoshandura simba rezuva mumagetsi emagetsi, uye simba rekuchengetedza simba rinochengetedza simba remagetsi rinogadzirwa ne photovoltaic equipment. Kana ichi chikamu chesimba remagetsi chichidikanwa, chinoshandurwa kuita chinochinjanisa ikozvino kuburikidza neshanduko yekuchengetera simba rekutakura kana kushandisa grid.
02, Tsanangudzo yemazwi akakosha
Zvinoenderana netsananguro yaBaidu: muhupenyu, dzimwe nguva dzinoda kushandura AC simba kuita DC simba, inova dunhu rekugadzirisa, uye mune dzimwe nguva, zvinodikanwa kushandura DC simba kuita AC simba. Iyi reverse process inoenderana nekugadzirisa inotsanangurwa se inverter circuit. Pasi pemamwe mamiriro, seti yemaseketi e thyristor anogona kushandiswa seese ari maviri rectifier wedunhu uye inverter wedunhu. Chishandiso ichi chinonzi chinoshandura, chinosanganisira rectifiers, inverters, AC converters, uye DC converters.
Ngatinzwisise zvakare:
Chirungu cheshanduro inoshandura, iyo inowanzoonekwa nemagetsi emagetsi zvikamu, uye basa rayo nderekuziva kufambiswa kwesimba. Zvinoenderana nemhando dzakasiyana dzemagetsi pamberi uye mushure mekushandura, yakakamurwa kuva anotevera marudzi:
DC / DC inoshandura, kumberi uye kumashure kune DC, iyo voltage yakasiyana, basa reDC transformer
AC/DC inoshandura, AC kuenda kuDC, basa remugadzirisi
DC / AC inoshandura, DC kuenda kuAC, basa reiyo inverter
AC / AC inoshandura, kumberi uye kumashure ma frequency akasiyana, basa reiyo frequency converter
Pamusoro peiyo huru dunhu (zvichitevera rectifier redunhu, inverter seketi, AC shanduko yedunhu uye DC shanduko yedunhu), inoshandura inodawo kuve neinokonzeresa dunhu (kana dhiraivha yedhiraivha) kudzora pa-kudzima kwesimba rekuchinja chinhu uye ziva kudzorwa kwesimba remagetsi, control circuit.
Iro zita rechirungu rekushandura simba rekuchengetedza simba iPower Conversion System, inonzi PCS, iyo inodzora kuchaja nekuburitsa bhatiri uye kuita shanduko yeAC-DC. Iyo inoumbwa neDC/AC bidirectional converter uye control unit.
03, PCS general classification
Inogona kupatsanurwa kubva kumaindasitiri maviri akasiyana, photovoltaic uye kuchengetedza simba, nekuti mabasa anoenderana akasiyana zvakanyanya:
Mune photovoltaic industry, pane: centralized type, tambo mhando, micro inverter
Inverter-DC ku AC: Basa guru ndere kushandura yakananga ikozvino inoshandurwa nemagetsi ezuva kuti iite alternating current kuburikidza ne photovoltaic equipment, inogona kushandiswa nemitoro kana kubatanidzwa mugridi kana kuchengetwa.
Pakati pepakati: chiyero chekushandisa yakakura-yepasi magetsi zviteshi, akagoverwa maindasitiri uye ekutengesa photovoltaics, uye simba rekubuda rose rakakura kupfuura 250KW.
Rudzi rwetambo: chiyero chekushandisa yakakura-yepasi magetsi zviteshi, yakagoverwa maindasitiri uye ekutengesa photovoltaics (general kubuda simba isingasviki 250KW, matatu-chikamu), imba photovoltaics (yakajairwa kubuda simba isingasviki kana yakaenzana ne10KW, imwe-chikamu) ,
Micro-inverter: chiyero chekushandisa chakagoverwa photovoltaic (general gout power ishoma pane kana kuenzana ne5KW, matatu-phase), imba photovoltaic (yakajairwa kubuda simba isingasviki kana kuenzana ne2KW, imwe-chikamu)
Magetsi ekuchengetedza masisitimu anosanganisira: hombe chengetedzo, maindasitiri uye ekutengesa ekuchengetedza,kuchengetedza mhuri, uye inogona kukamurwa kuita magetsi ekuchengetedza simba (chinyakare simba rekuchengetedza magetsi, Hybrid) uye akasanganiswa michina.
Shanduko-AC-DC shanduko: Basa guru ndere kudzora kubhadharisa uye kubuda kwebhatiri. Iyo DC simba rinogadzirwa ne photovoltaic simba rekugadzira rinoshandurwa kuita AC simba kuburikidza ne inverter. Ikozvino inochinja inoshandurwa kuita yakananga ikozvino yekuchaja. Kana ichi chikamu chesimba remagetsi chichidikanwa, iyo yakananga ikozvino mubhatiri inoda kushandurwa kuita inochinjanisa ikozvino (kazhinji 220V, 50HZ) neinoshandura simba rekuchengetedza kuti ishandiswe nemutoro kana kubatana kune grid. Uku ndiko kubuda. process.
Kuchengetera kwakakura: chiteshi chemagetsi epasi, yakazvimirira simba rekuchengetedza simba chiteshi, iyo yakajairika yekubuda simba yakakura kupfuura 250KW
Indasitiri uye yekutengesa kuchengetedza: general kubuda simba ishoma pane kana kuenzana ne250KW
Chengetedzo yemumba: simba remagetsi rinobuda riri pasi kana kuenzana ne10KW
Echinyakare ekuchengetedza simba anoshandura: kunyanya shandisa iyo AC coupling scheme, uye mamiriro ekushandisa anonyanya kuchengetwa hombe.
Hybrid inverter: inonyanya kutora iyo DC coupling scheme, uye mamiriro ekushandisa anonyanya kuchengetedza imba
All-in-one inverter: inoshandura simba rekuchengetedza simba + bhatiri paki, zvigadzirwa zvinonyanya Tesla uye Ephase
