Sechikamu chakakosha chekugadzira simba re photovoltaic, basa guru re inverter nderekushandura direct current kubva kuma photovoltaic modules kuita alternating current. Parizvino, inverter yakajairika iri pamusika inonyanya kupatsanurwa mu centralized inverter uye group series inverter, uye inverter itsva yakagoverwa.
Mashandiro azvinoita:
· Series inverter: nhevedzano yemasero e photovoltaic kuita input ye DC ine voltage yakawanda, uye yozoshandurwa kuita AC output.
· Parallel inverters: masero akawanda e photovoltaic akabatana parallel kuti awedzere huwandu hwemagetsi, ayo anozoshandurwa kuita AC output.
· Muchina wekuchinja mabhiriji: kushandiswa kwedunhu rebhiriji pakushandura dc-to-ac.
· Intermediate-frequency inverter: nekushandura DC input kuita intermediate-frequency AC, iyo inoshandurwa mutransformer kuti iwane AC output inodiwa.
Zvichibva pane waveform inobuda:
· Sine wave inverter: chinobuda iwaya ine sine yakachena, yakakodzera zvinodiwa zvemhando yepamusoro yesimba remagetsi.
· Inverter ye sinusoidal yakagadziriswa: waveform inobuda iwaveform ye sinusoidal yakagadziriswa, ine zvimwe zvikamu zve harmonic zvakachekwa kushandiswa mudzimba nemabhizimisi.
· Muchina wekugadzirisa mafungu emativi mana: muchina wekugadzirisa mafungu emativi mana une mafungu emativi mana, uri nyore uye wakaderera, asi uchaunza mamwe maharmoniki.
· Inverter yePulse width modulation (PWM): kushandiswa kwetekinoroji yePWM yepamusoro kugadzira waveform inobuda near-sinusoidal.
Zvichienderana nenzvimbo dzekushandisa:
· Inverter yakazvimirira: yemasisitimu ekugadzira magetsi akazvimirira asina grid guru remagetsi, akadai semwenje, magetsi, nezvimwewo.
· Solar inverter: batanidza simba re photovoltaic kugrid huru woisa simba rakawandisa mugrid kana risingadiwi, wowana simba risina kukwana kubva kugrid.
· Micro-grid inverter: sisitimu ye micro-grid inogona kuwana networking uye management, ichave nemagetsi akasiyana (akadai sezuva, mhepo, nezvimwewo) uye mutoro wakabatana.
Aya ndiwo mamwe mapoka emagetsi ezuva anowanzo shandiswa. Mhando dzakasiyana dzemagetsi ezuva dzine hunhu hwakasiyana uye mamiriro ezvinhu anoshanda. Zvakakosha kusarudza mhando yemagetsi ezuva zvichienderana nezvinodiwa uye mamiriro ezvinhu ekushandiswa.
Chii chinonzi solar inverter:
Iyo solar inverter inoshandiswa kushandura direct current (DC) inogadzirwa nemapaneru e photovoltaic (mapaneru ezuva) kuita alternating current (AC). Mapaneru e photovoltaic anoshandura chiedza chezuva kuita direct current, uye solar inverter inoshandura direct current iyoyo kuita alternating current yatinowanzo shandisa kupa magetsi mudzimba, maindasitiri nemabhizinesi.
Mabasa makuru e solar inverter ndeaya anotevera:
1. Kuchinja Simba: simba rinobuda mu solar panel reDC mu AC kuti rienderane nezvinodiwa ne power grid. Alternating current (AC) ndiyo mhando yesimba remagetsi rinoshandiswa muhupenyu hwedu hwezuva nezuva uye mukugadzirwa kwemaindasitiri.
2. Grid-connected: kune masisitimu e photovoltaic akabatana negrid, solar inverter inogona kuisa simba rakawandisa mugrid kuderedza kuvimba negrid uye kugadzira mari yakati wandei online.
3. Kutarisira simba: solar inverter inowanzo kwanisa kutarisa nekutarisira sisitimu yePV, kutarisa mamiriro, magetsi, voltage, nezvimwewo zvepaneru yePV munguva chaiyo, kupa vashandisi kugona kwekutarisa nekuvandudza mashandiro emasisitimu ePV.
4. Mabasa ekudzivirira: solar inverter inowanzo kuve nedziviriro yekuwedzeredza, dziviriro yepfupi, dziviriro yekuwedzeredza, dziviriro yekusawedzera simba, nezvimwewo kuti ive nechokwadi chekuti PV system inoshanda zvakachengeteka.
Muchidimbu, solar inverter inoita basa rakakosha mu photovoltaic systems, ichishandura simba rechiedza kuita alternating current inobatsira, ichibvumira simba rezuva kushandiswa pakupa magetsi uye kuwana grid, kuzadzisa zvinangwa zvebudiriro inochengetedza simba uye kuderedza utsi.
Zvinhu zvikuru zve inverter zvinosanganisira zvinotevera:
1. Mudziyo weSemiconductor: chinhu chikuru cheinverter mudziyo wePower semiconductor, unowanzo shandisa power Transistor (IGBT) kana Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). Midziyo iyi inoshandiswa kushandura simba remagetsi kubva kuDC kuenda kuAC.
2. MaCapacitor nemaInductor: maCapacitor nemaInductor anoshandiswawo mumaInverters kuchengetedza nekusefa simba remagetsi. MaCapacitor anogadzirisa voltage inobuda uye current, ukuwo maInductor achisefa ruzha rwepamusoro-soro uye harmonics.
3. Chishandiso chekupisa nechinhu chinodziya: Chishandiso chemagetsi chiri mu inverter chinoburitsa kupisa kwakawanda, chinoda chinhu chinodziya nechinhu chinodziya kuti chideredze kupisa zvinobudirira, uye chive nechokwadi chekuti mudziyo unoshanda zvakanaka. Ma radiator anowanzo gadzirwa nearuminiyamu kana mhangura kuti ape nzvimbo yakakwana yekutonhodza.
4. PCB (Bhodhi reDunhu Rakadhindwa): PCB ndiyo inotakura kuiswa nekubatanidza zvikamu zvemagetsi mu inverter, ine conductivity yakanaka yemagetsi uye simba remakanika. Dhizaini yedunhu re inverter ichaenderana nezvinodiwa nesimba uye marongerwo edunhu re wiring nekubatanidza zvinoenderana.
5. Zvikamu zvemagetsi nezvikamu zvedunhu: inverter inodawo kushandisa zvikamu zvakasiyana-siyana zvedunhu, zvakaita semadiode, resistors, transformers, fuses, connectors, nezvimwewo. pakudzora, kudzivirira uye kubatana kwedunhu.
Pamusoro pezvo, bhokisi remuchina we inverter rinowanzo gadzirwa nezvinhu zvesimbi, zvakaita se aruminiyamu alloy kana simbi, zvinoshandiswa kudzivirira zvakanaka michina uye kupisa.
Izvi ndizvo zvinhu zvikuru zve inverter, zvinhu izvi mukugadzira nekugadzira inverter zvinoita basa rakakosha pakuona kuti inverter inoshanda uye yakavimbika.
