Inverter yemagetsi isina grid

Nhanganyaya yeChigadzirwa
Iyo PV off-grid inverter chishandiso chekushandura simba chinosunda nekudhonza chinowedzera simba remagetsi reDC rekupinda uye chobva charishandura kuita simba re220V AC kuburikidza ne inverter bridge SPWM sinusoidal pulse width modulation technology.
Kufanana nema inverters akabatana negrid, ma inverters ePV off-grid anoda kushanda zvakanaka, kuvimbika kwakanyanya, uye huwandu hwakasiyana hwemagetsi ekupinda eDC; mumasisitimu emagetsi ePV ane simba repakati nerepamusoro, kubuda kwe inverter kunofanirwa kunge kuri sinusoidal wave ine kukanganiswa kwakaderera.

Kushanda uye Zvimiro
1. 16-bit microcontroller kana 32-bit DSP microprocessor inoshandiswa kudzora.
2.PWM control mode, inovandudza zvikuru mashandiro.
3. Adopt digital kana LCD kuratidza ma parameter akasiyana-siyana ekushanda, uye inogona kuisa ma parameter akakodzera.
4. Mafungu emativi mana, mafungu akagadziriswa, mafungu esine. Mafungu anobuda, mafungu esine, mwero wekukanganisika kwechimiro chewave uri pasi pe5%.
5. Kururama kwekudzikamisa voltage yepamusoro, mutoro uri pasi pechiyero, kunyatsobuda kwemhedzisiro kazhinji kunenge kuri pasi pe plus kana minus 3%.
6. Kutanga zvishoma nezvishoma kudzivirira kukanganiswa kwakawanda kwemagetsi pabhatiri nemutoro.
7. Kupatsanura transformer ine frequency yakakura, saizi diki uye huremu hwakareruka.
8. Yakashongedzerwa neinterface yekutaurirana yeRS232/485, yakakodzera kudzora kutaurirana kuri kure.
9. Inogona kushandiswa munzvimbo iri pamusoro pe5500 metres pamusoro pegungwa.
10. Iine dziviriro yekubatanidza reverse, dziviriro yekupinda undervoltage, dziviriro yekupinda overvoltage, dziviriro yekupinda overvoltage, dziviriro yekupinda overvoltage, dziviriro yekupinda overload, dziviriro yekupinda short circuit, dziviriro yekupisa zvakanyanya uye mamwe mabasa ekudzivirira.

Zviyero zvakakosha zvehunyanzvi zvema inverters asina grid
Pakusarudza inverter isina grid, kunze kwekuteerera ma waveform anobuda uye rudzi rwe isolation ye inverter, kune mamwe ma technical parameters akakoshawo, akadai se system voltage, output power, peak power, conversion efficiency, switching time, nezvimwewo. Kusarudzwa kwema parameters aya kune simba guru pakudiwa kwemagetsi emutoro.
1) Vheji yemagetsi:
Ndiwo voltage yebhatiri. Voltage yekupinda yeinverter iri kunze kwegrid uye voltage yekubudisa yecontroller zvakafanana, saka pakugadzira nekusarudza modhi, chenjerera kuti irambe yakafanana necontroller.
2) Simba rekuburitsa:
Kubuda kwesimba remagetsi kubva pamagetsi e-inverter ari kunze kwegrid kune mhando mbiri, imwe yacho inonzi pachena, iyo unit ndiVA, iyi ndiyo reference UPS mark, simba remagetsi rinobuda rinofanirawo kuwedzera simba, senge 500VA off-grid inverter, simba remagetsi i0.8, simba remagetsi rinobuda i400W, kureva kuti, rinogona kutyaira 400W resistive load, senge mwenje yemagetsi, ma induction cooker, nezvimwewo; yechipiri inonzi active power expression, iyo unit ndiW, senge 5000W off-grid inverter, simba remagetsi rinobuda i5000W.
3) Simba repamusoro-soro:
Mu PV off-grid system, ma modules, mabhatiri, ma inverter, ma loads zvinoumba system yemagetsi, simba re inverter rinobuda, rinotsanangurwa nemutoro, mimwe mitoro inopinda, senge ma air conditioners, ma pombi, nezvimwewo, mota iri mukati, simba rekutanga rinopetwa katatu kusvika kashanu kupfuura simba rakatarwa, saka inverter iri kunze kwegrid ine zvinodiwa zvakakosha zvekuremerwa. Simba repamusoro ndiro simba re overload re inverter iri kunze kwegrid.
Iyo inverter inopa simba rekutanga kumutoro, chikamu kubva kubhatiri kana PV module, uye yakawandisa inopihwa nezvikamu zvekuchengetera simba mukati meinverter - ma capacitor nema inductors. Ma capacitor nema inductors ese ari maviri zvikamu zvekuchengetera simba, asi musiyano ndewekuti ma capacitor anochengeta simba remagetsi muchimiro chemunda wemagetsi, uye kana capacitor ikakura, simba rayo rinogona kuchengeta. Kune rumwe rutivi, ma inductor anochengeta simba muchimiro chemunda wemagnetic. Kana magnetic permeability ye inductor core yakakura, inductance yakakura, uye simba rakawanda rinogona kuchengetwa.
4) Kushanda zvakanaka kwekushandura:
Kushanda zvakanaka kwekushandura system yeOff-grid kunosanganisira zvinhu zviviri, chimwe ndechekuti muchina wacho unoshanda zvakanaka, dunhu reinverter reoff-grid rakaoma, rinogona kupfuudzwa nenzira dzakasiyana-siyana, saka kushanda zvakanaka kwacho kwakaderera zvishoma pane inverter yakabatana negrid, kazhinji pakati pe80-90%, simba remuchina weinverter rinokura, kupatsanurwa kwema frequency akawanda kupfuura kushanda zvakanaka kwe frequency, uye kushanda zvakanaka kwemagetsi esystem kunowedzerawo. Chechipiri, kushanda zvakanaka kwekuchaja nekuburitsa bhatiri, iyi ndiyo mhando yebhatiri ine hukama, kana kugadzirwa kwesimba re photovoltaic uye kuenderana kwesimba remutoro, photovoltaic inogona kupa mutoro wekushandisa zvakananga, pasina chikonzero chekuchinja bhatiri.
5) Nguva yekuchinja:
Sisitimu yeOff-grid ine mutoro, kune nzira nhatu dzePV, bhatiri, utility, kana simba rebhatiri risina kukwana, chinja kuenda ku utility mode, pane nguva yekuchinja, mamwe ma inverter eoff-grid anoshandisa electronic switch switch, nguva iri mukati memamirisekonzi gumi, makomputa edesktop haadzime, mwenje haudzime. Mamwe ma inverter eoff-grid anoshandisa relay switching, nguva inogona kunge inopfuura mamirisekonzi makumi maviri, uye komputa yedesktop inogona kudzima kana kutangazve.
