I-Photovoltaic off-grid inverter

Isingeniso Somkhiqizo
I-PV Off-Grid Inverter iyithuluzi lokuguqulwa elinamandla elidlulela kulo amandla okufaka ama-DC bese lingena emandleni angama-220v ac nge-Inverter Bridge Sinusoidal Pulse
Njengama-inverters axhunywe nge-grid, ama-pv off-grid amandla adinga ukusebenza okuphezulu, ukuthembeka okuphezulu, kanye nohlu olubanzi lwe-DC Inpul Voltage; Kuzinhlelo ze-PV amandla aphakathi nendawo, okukhishwayo kwe-inverter kufanele kube yi-sinusoidal wave ngokuhlanekezela okuphansi.

Ukusebenza Nezici
1. I-16-bit microcontroller noma i-32-bit DSP Microprocessor isetshenziselwa ukulawula.
Imodi yokulawula ye-2.PWM, ithuthukise kakhulu ukusebenza kahle.
I-3.adopt digital noma i-LCD ukubonisa amapharamitha ahlukahlukene wokusebenza, futhi ingasetha amapharamitha afanele.
4. I-Square Wave, i-Wave eguquliwe, okukhipha ama-Sine Wave. Ukukhishwa kwe-Sine Wave, izinga lokuhlanekezela lokuhlanekezela lingaphansi kwama-5%.
I-5
I-6. Umsebenzi we-Slow Start ukugwema umthelela omkhulu wamanje ebhethri nomthwalo.
7. I-High Frequency Transformer ihlukaniswa, usayizi omncane nesisindo esikhanyayo.
8. Ihlome ngesikhombimsebenzisi sokuxhumana esijwayelekile se-RS232 / 485, elula yokulawula okukude kokuxhumana.
9. Ingasetshenziswa endaweni engenhla kwamamitha angama-5500 ngaphezulu kwezinga lolwandle.
I-10, ngokuvikelwa kokuxhunywa okubuyiselwe emuva, ukuvikelwa kokufakwa kwama-undervoltage, ukuvikelwa kwama-overvoltage, okuvikelekile kokukhishwa ngokweqile, ukuvikelwa okukhiqizwa ngokweqile, ukuvikelwa kokukhipha okuphumayo, ukuvikelwa ngokweqile kanye neminye imisebenzi.

Amapharamitha abalulekile wezobuchwepheshe we-inverters off-grid
Lapho ukhetha i-inverter off-grid, ngaphandle kokunaka i-wavexform ye-wavexform kanye ne-inverter ye-inverter, kunamapharamitha amaningi wezobuchwepheshe abaluleke kakhulu, njengamandla aphezulu wesistimu, amandla okuphuma, amandla okuguqula, isikhathi sokushintsha, Njll. Ukukhethwa kwalawa mapharamitha kunomthelela omkhulu kwisidingo sikagesi somthwalo.
1) I-System Voltage:
Kungamandla kagesi wephakethe lebhethri. I-voltage yokufaka ye-inverter-yegridi ye-off-grid kanye ne-voltage ekhishwayo yesilawuli iyafana, ngakho-ke lapho uklama futhi ukhetha imodeli, unake ukuqhubeka unjalo ngesilawuli.
2) Amandla okukhipha:
Ukukhishwa kwamandla kagesi okungekho-grid kunezinhlobo ezimbili, enye indlela ebonakalayo yamandla, iyunithi yi-VA, le yinkomba kamaki, amandla okusebenza angokoqobo nawo adinga ukwengeza isici samandla, njenge-500va off-grid inverter , i-Power Factor ingu-0,8, amandla angokoqobo asebenzayo angama-400w, okusho ukuthi, angashayela umthwalo we-400w wokuthula, njengamalambu kagesi, abapheki be-invances, njll.; Okwesibili kungukubonisa kwamandla asebenzayo, iyunithi yi-W, njenge-5000wf off-grid inverter, amandla wangempela wokuphuma angu-5000w.
3) Amandla we-Peak:
Kuhlelo lwe-PV Off-Grid, amamojula, amabhethri, ama-inverter, imithwalo akha uhlelo kagesi, amandla okukhipha, anqunywa umthwalo womoya, amaphampu, njll. Amandla okuqala ahlale izikhathi ezi-3-5 amandla alinganiselwe, ngakho-ke i-Off-Grid Inverter inezidingo ezikhethekile zokulayishwa ngokweqile. Amandla okuphezulu awonke amakhono aphezulu we-inverter off-grid.
I-inverter ihlinzeka ngamandla wokuqalisa emthwalweni, ngokwengxenye kusuka kumojula yebhethri noma ye-PV, futhi okweqile kuhlinzekwa ngezinto zokugcina amandla ngaphakathi kwe-inverter - ama-capacitors kanye ne-inductor. Ama-capacitors kanye ne-inductors zombili izingxenye zokugcinwa kwamandla, kepha umehluko ukuthi ama-capacitors agcina amandla kagesi ngendlela yensimu kagesi, futhi enkulu umthamo we-capacitor, amandla amaningi angawagcina. Ngakolunye uhlangothi, ama-Inductor, agcina amandla ngendlela kazibuthe. Lapho kukhula inani le-magnetic permeability ye-inductor core, okukhulu kakhulu kwe-inductance, namandla amaningi angagcinwa.
4) Ukuguqulwa kokuguqulwa:
Ukusebenza kahle kwe-Off-Grid System kufaka phakathi izici ezimbili, enye indlela yokusebenza komshini uqobo, i-Off-Grid Inverter Circuit iyinkimbinkimbi, ukuze iguqulwe i-multi-stage, ngakho-ke ukusebenza okuphelele kuphansi kancane kune-inverter exhunywe yigridi, ngokuvamile Phakathi kuka-80-90%, kwalapho amandla amakhulu omshini we-Inverter, ukuhlukaniswa okuthe xaxa okuphezulu kokuhlukaniswa kwe-frequency isolate kuphakeme, kuphakama i-System Voltage Effession. Okwesibili, ukusebenza kahle kokushaja kwebhethri nokukhipha, lolu hlobo lwebhethri olunobudlelwano, lapho ukukhiqizwa kwamandla okulayisha nokulayishwa kwamandla okulayishwa, i-Photovoltaic ingakunikeza ngokuqondile umthwalo ongawasebenzisa, ngaphandle kwesidingo sokudlula ekuguqukeni kwebhethri.
5) Isikhathi sokushintsha:
Isistimu ye-Off-Grid enomthwalo, kukhona i-PV, ibhethri, izindlela ezintathu zezindlela ezinganele, shintshela kwimodi yokusebenzisa, kukhona isikhathi sokushintsha, isikhathi esingu-10 millonity, Amakhompiyutha e-Desktop ngeke avale phansi, ukukhanyisa ngeke kufane. Abanye abakwa-Inverters off-grid basebenzisa ukushintshana okudluliselwe emuva, isikhathi singaba ngaphezu kwama-20 millisecond, futhi ikhompyutha yedeskithophu ingavala noma iqale kabusha.
