Inverter ke mofuta oa sesebelisoa sa tokiso ea matla se entsoeng ka lisebelisoa tsa semiconductor, tse sebelisoang haholo ho fetolela matla a DC ho ba matla a AC, hangata a entsoe ka potoloho ea boost le inverter bridge.Potoloho e matlafatsang e eketsa motlakase oa DC oa sele ea letsatsi ho ea ho motlakase oa DC o hlokoang ke taolo ea tlhahiso ea inverter;Potoloho ea borokho ba inverter e fetola motlakase oa DC o matlafalitsoeng hore e be motlakase o tloaelehileng oa AC ka ho lekana.
Inverter, e tsejoang hape e le taolo ea matla, e ka aroloa ka mefuta e 'meli ea phepelo ea motlakase e ikemetseng le e hokahaneng le grid ho latela ts'ebeliso ea inverter ho sistimi ea ho fehla matla a photovoltaic.Ho latela mokhoa oa waveform modulation, e ka aroloa ka square wave inverter, step wave inverter, sine wave inverter le inverter ea mekhahlelo e meraro.Bakeng sa inverter e sebelisoang tsamaisong ea marang-rang e amanang le marang-rang, ho latela boteng kapa ho ba sieo ha transformer e ka aroloa ka mofuta oa transformer inverter le transformer type inverter.Mekhahlelo ea mantlha ea tekheniki ea solar photovoltaic inverter ke:
1. Rated output voltage
Pv inverter e lokela ho khona ho ntša motlakase o lekantsoeng ka har'a mefuta e lumelletsoeng ea ho feto-fetoha ha motlakase o boletsoeng oa dc.Ka kakaretso, ha motlakase o lekantsoeng e le 220v le mokhahlelo o le mong oa 380v, ho kheloha ha motlakase ho na le lipehelo tse latelang.
(1) Ts'ebetsong ea boemo bo tsitsitseng, phallo ea phallo ea motlakase hangata e hlokahala hore e se fete ± 5% ea boleng bo lekantsoeng.
(2) Ho kheloha ha motlakase ha hoa lokela ho feta ± 10% ea boleng bo lekantsoeng tabeng ea phetoho ea mojaro.
(3) Tlas'a maemo a tloaelehileng a ho sebetsa, tekanyo e sa leka-lekaneng ea phallo ea motlakase ea mekhahlelo e meraro ea inverter ha ea lokela ho feta 8%.
(4) Ho sotha ha maqhubu a motlakase oa mekhahlelo e meraro (sine wave) ha hoa lokela ho feta 5%, 'me tlhahiso ea karolo e le' ngoe ha ea lokela ho feta 10%.
(5) Inverter output AC voltage frequency frequency tlas'a maemo a tloaelehileng a ho sebetsa ho kheloha ha eona ho lokela ho ba ka hare ho 1%.Maqhubu a motlakase a hlahisoang a boletsoeng ho standard standard ea naha ea gb/t 19064-2003 e lokela ho ba lipakeng tsa 49 le 51hz.
2, mojaro matla ntlha
Ntho ea matla ea mojaro e bonts'a bokhoni ba inverter e nang le mojaro oa inductive kapa mojaro oa capacitive.Tlas'a maemo a sine wave, matla a motlakase a tloha ho 0.7 ho isa ho 0.9, 'me tekanyo ke 0.9.Tabeng ea matla a itseng a mojaro, haeba matla a motlakase a inverter a le tlaase, matla a hlokahalang a motlakase a tla eketseha, a lebisang ho eketseha ha litšenyehelo, ka nako e ts'oanang, matla a bonahalang a photovoltaic system AC loop e eketseha, Loop e eketseha hona joale, tahlehelo e tla eketseha, 'me katleho ea sistimi e tla fokotseha.
3. Rated tlhahiso hona joale le bokgoni
Tekanyetso ea hona joale e hlahisoang e bua ka tlhahiso e lekantsoeng ea inverter ka har'a mefuta e boletsoeng ea matla a matla (yuniti: A).Bophahamo ba tlhahiso e lekantsoeng ke sehlahisoa sa motlakase o lekantsoeng o hlahisoang mme o lekantsoe tlhahiso ea hona joale ea inverter ha motlakase o hlahisoang e le 1 (ke hore, mojaro o hloekileng o hanyetsang), ho KVA kapa kW.
