Photovoltaic ke eng, polokelo ea matla ke eng, converter ke eng, inverter ke eng, PCS le mantsoe a mang a bohlokoa
01, Ho boloka matla le photovoltaic ke liindasteri tse peli
Kamano e teng pakeng tsa bona ke hore tsamaiso ea photovoltaic e fetola matla a letsatsi hore e be matla a motlakase, 'me tsamaiso ea polokelo ea matla e boloka matla a motlakase a hlahisoang ke lisebelisoa tsa photovoltaic. Ha karolo ena ea matla a motlakase e hlokahala, e fetoloa ho fetoha hona joale ka sesebelisoa sa polokelo ea matla bakeng sa tšebeliso ea mojaro kapa grid.
02, Tlhaloso ea mantsoe a bohlokoa
Ho ea ka tlhaloso ea Baidu: bophelong, linako tse ling li hloka ho fetola matla a AC hore e be matla a DC, e leng potoloho ea tokiso, 'me ka linako tse ling, hoa hlokahala ho fetola matla a DC hore e be matla a AC. Ts'ebetso ena e fapaneng e tsamaellanang le tokiso e hlalosoa e le potoloho ea inverter. Tlas'a maemo a itseng, sete ea li-circuits tsa thyristor li ka sebelisoa e le potoloho ea rectifier le potoloho ea inverter. Sesebelisoa sena se bitsoa converter, e kenyelletsang li-rectifiers, li-inverters, li-converter tsa AC, le li-converter tsa DC.
Ha re utloisise hape:
Senyesemane sa converter ke converter, eo ka kakaretso e lemohuoang ka likarolo tsa elektronike tsa matla, 'me mosebetsi oa eona ke ho hlokomela phetiso ea matla. Ho ea ka mefuta e fapaneng ea motlakase pele le ka mor'a phetoho, e arotsoe ka mefuta e latelang:
DC / DC converter, ka pele le ka morao ke DC, motlakase o fapane, mosebetsi oa motlakase oa DC
AC / DC converter, AC ho DC, karolo ea mohlophisi
DC / AC converter, DC ho AC, karolo ea inverter
AC/AC converter, maqhubu a ka pele le a ka morao a fapane, karolo ea mofetoleli oa maqhubu
Ntle le potoloho ea mantlha (ka ho latellana rectifier circuit, inverter circuit, AC converter circuit le DC conversion circuit), converter e boetse e hloka ho ba le trigger circuit (kapa drive circuit) ho laola ho tima ha ntho ea motlakase le ho hlokomela taolo ea matla a motlakase, taolo ea potoloho.
Lebitso la Senyesemane la converter ea polokelo ea matla ke Power Conversion System, e bitsoang PCS, e laolang ts'ebetso ea ho tjhaja le ho ntša betri le ho fetola AC-DC. E entsoe ka DC/AC bidirectional converter le unit control.
03, PCS kakaretso sehlopha
E ka aroloa ho tsoa liindastering tse peli tse fapaneng, photovoltaic le polokelo ea matla, hobane mesebetsi e lumellanang e fapane haholo:
Ka indasteri ea photovoltaic, ho na le: mofuta o bohareng, mofuta oa likhoele, micro inverter
Inverter-DC ho AC: Mosebetsi o ka sehloohong ke ho khelosa motlakase o tobileng o fetotsoeng ke matla a letsatsi hore o fetohe hona joale ka lisebelisoa tsa photovoltaic, tse ka sebelisoang ke meroalo kapa ho kenngoa ka har'a marang-rang kapa ho bolokoa.
Bohareng: boholo ba ts'ebeliso ke liteishene tse kholo tsa matla a fatše, li-photovoltaics tsa indasteri le tsa khoebo tse ajoang, 'me matla a kakaretso a tsoang a feta 250KW.
Mofuta oa likhoele: boholo ba ts'ebeliso ke liteishene tse kholo tsa matla a fatše, li-photovoltaics tsa indasteri le tsa khoebo (kakaretso ea matla a ka tlase ho 250KW, mekhahlelo e meraro), li-photovoltaics tsa malapa (matla a kakaretso a hlahisoang ka tlase kapa a lekanang le 10KW, mohato o le mong) ,
Micro-inverter: boholo ba ts'ebeliso bo ajoa photovoltaic (matla a kakaretso a hlahisoang a tlase kapa a lekana le 5KW, mekhahlelo e meraro), photovoltaic ea lelapa (matla a kakaretso a hlahisoang a ka tlase kapa a lekana le 2KW, mohato o le mong)
Sistimi ea polokelo ea matla e kenyelletsa: polokelo e kholo, polokelo ea indasteri le ea khoebo,polokelo ea lelapa, 'me e ka aroloa ka li-converter tsa polokelo ea matla (li-converter tsa setso tsa polokelo ea matla, Hybrid) le mechine e kopantsoeng
Phetoho ea converter-AC-DC: Mosebetsi oa mantlha ke ho laola tjhaja le ho tsoa ha betri. Matla a DC a hlahisoang ke motlakase oa photovoltaic a fetoloa matla a AC ka inverter. Mohala o fapanyetsanoang o fetoloa hore e be oa hona joale o tobileng bakeng sa ho tjhaja. Ha karolo ena ea matla a motlakase e hlokahala, motlakase o tobileng ka har'a betri o hloka ho fetoloa hona joale (ka kakaretso 220V, 50HZ) ke converter ea polokelo ea matla bakeng sa ho sebelisoa ke mojaro kapa ho hokahanngoa le marang-rang. Sena ke ho tsoa. tshebetso.
Sebaka se seholo sa polokelo: seteishene sa matla a fatše, seteishene sa matla sa polokelo ea matla se ikemetseng, matla a kakaretso a tsoang a feta 250KW
Liindasteri le polokelo ea khoebo: matla a tlhahiso ea kakaretso a tlase kapa a lekana le 250KW
Polokelo ea ka tlung: matla a kakaretso a tsoang a tlase kapa a lekana le 10KW
Li-converter tsa setso tsa polokelo ea matla: haholo-holo li sebelisa leano la ho kopanya AC, 'me maemo a ts'ebeliso ke polokelo e kholo haholo.
Hybrid inverter: haholo-holo e amohela morero oa ho kopanya oa DC, 'me boemo ba kopo ke haholo-holo polokelo ea malapa
All-in-one inverter: converter ea polokelo ea matla + betri pakete, lihlahisoa haholo-holo Tesla le Ephase
