Abagororwa ba PhotoVeltaic bafite amahame ya tekiniki nka bayondo basanzwe. Intingu zose zigomba kubahiriza ibipimo bya tekinike bikurikira kugirango bisuzumwe ibicuruzwa byujuje ibyangombwa.
1. Kuruhuka voltage
Muri sisitemu ya PhotoVoltaic, ingufu z'amashanyarazi zakozwe na selile yizuba zibitswe bwa mbere na bateri, hanyuma zica muri 220v cyangwa 380V gusimbugura unyuze muri inverter. Ariko, bateri yibasiwe nubwishyu bwayo no gusohoka, hamwe nibisohoka voltage iratandukanye cyane. Kurugero, kuri bateri ifite nomil 12v, agaciro ka voltage karashobora gutandukana hagati ya 10.8 na 14.4V (kurenza iyi nkuru birashobora gutera ibyangiritse kuri bateri). For a qualified inverter, when the input voltage changes within this range, the change of the steady-state output voltage should not exceed ±5% of the rated value, and when the load changes suddenly, the output voltage deviation should not exceed ±10% of rated value.
2. Umuhengeri wagoreka ibisohoka voltage
Kuri sine wavers, ntarengwa ntarengwa yo kugoreka (cyangwa guhuza ibikubiyemo) bigomba gusobanurwa. Mubisanzwe bigaragazwa nko kugoreka byose byavuyemo voltage, agaciro kayo ntigomba kurenga 5% (ibisohoka bimwe bisohoka bituma 10%). Kubera ko itondekanya riremwe zikurikiranwa na Inverter rizabyara inyongera nka Eddy iri kumutwaro wa Inductive, niba bidatera urujijo rwibice byimitwaro, bidateza imbere ibice byimitwaro, bidafasha cyane umutekano wibikoresho by'amashanyarazi kandi bigira ingaruka zikomeye kuri sisitemu. gukora neza.
3.
Erega imitwaro harimo moteri, nko gukaraba, abahagaritse imashini, nibindi, kubera ko inshuro zidasanzwe za moteri ari 50hz, zizatera ibikoresho byo gushyuha no kugabanya imikorere ikora hamwe na serivisi. Ibisohoka inshuro bidakwiye kuba bifite agaciro gakomeye, mubisanzwe imbaraga inshuro nyinshi 50hz, kandi gutandukana kwayo bigomba kuba biri muri ± 1% mubihe bisanzwe.
4. Gutwara amashanyarazi
Kuranga ubushobozi bwinzogera kugirango utware inductive cyangwa imizigo. Umutwaro w'imbaraga za sine uhindagurika ni 0.7 kugeza 0.9, hamwe n'agaciro ni 0.9. Kubireba imbaraga zimwe zumutwaro, niba ingufu zanyuma ari nke, ubushobozi bukenewe bwikigo iziyongera, kizongera ikiguzi kandi cyongera imbaraga zigaragara za sisitemu ya ac of the sisitemu ya PhotoVoltaic. Nkuko ikiriho kiriyongera, igihombo kizakwiyongera rwose, kandi uburyo bwo gukora sisitemu nabwo buzagabanuka.
5. Kuvugaranwa
Imikorere ya inverter yerekeza kuri kiti cyibisohoka imbaraga zishingiye ku mbaraga zinjiza mubihe byagenwe, bigaragazwa nkijanisha. Muri rusange, imikorere yizina rya ectovoltaic bivuga umutwaro wo kurwanya, munsi ya 80%. S neza. Kubera ko ikiguzi rusange cya sisitemu ya PhotoVoltaic, inteko ya Photovoltaic igomba kumererwa cyane, gahunda ya sisitemu igomba kugabanywa, kandi imikorere-ikiguzi cya sisitemu ya Photovelletaic igomba kunozwa. Kugeza ubu, uburyo bw'izina bwa bagororotse biri hagati ya 80% na 95%, kandi imikorere ya bayobe nkeya irasabwa kuba munsi ya 85%. Mubishushanyo nyabwo bya sisitemu ya Photovoltaic, ntabwo bigomba gutorwa gusa, ariko icyarimwe, sisitemu igomba gushyirwaho neza kugirango ikore gahunda ya PhotoVoltaic Akazi hafi yingingo nziza bishoboka.
6.
Yerekana ibisohoka byerekeranye na Inverter muburyo bwateganijwe bwamashanyarazi. Ibicuruzwa bimwe byanyuma bitanga ubushobozi buke bwo gusohora, bugaragarira muri VI cyangwa KVA. Ubushobozi bwibintu ni mugihe ibisohoka imbaraga zidahwitse ari 1 (ni ukuvuga umutwaro urwanya), ibisohoka bisohoka voltage nigicuruzwa cyibisohoka bigezweho.
7. Ingamba zo kurinda
Inverter ifite imikorere myiza nayo igomba kuba ifite imikorere yuzuye cyangwa ingamba zo gukemura ibibazo bitandukanye bidasanzwe mugihe cyo gukoresha, kugirango intsinzi ubwayo nibindi bice bya sisitemu bitangiritse.
(1) Kwinjiza Politiki Yintangiriro:
Iyo winjiza voltage iri munsi ya 85% ya voltage yatanzwe, inverter igomba kurinda no kwerekana.
(2) Kwinjiza konti yubwishingizi bwikirenga:
Iyo kwinjiza voltage iri hejuru ya 130% ya voltage yatanzwe, inverter igomba kurinda no kwerekana.
(3) Kurinda birenze urugero:
Kurinda cyane inverter bigomba gushobora kwemeza ibikorwa mugihe umutwaro uheruka cyangwa ikigezweho kirenze agaciro kemewe, kugirango ubibuze kwangizwa no kwiyongera kurubu. Iyo akazi karenze 150% byagaciro, inverter igomba gushobora mu buryo bwikora.
(4) Ibisohoka Ingwate Ntoya
Imbere mu buryo buke bwo kurinda-gufungura igihe ntigomba kurenga 0.5s.
(5) Kwinjiza Ububiko Bwiza:
Iyo inkingi nziza kandi mbi za terefone zinjiza zahinduwe, inverter igomba kugira imikorere yo kurinda no kwerekana.
(6) Kurinda inkuba:
Incumoko igomba kugira inkuba.
(7) Kurinda Ubushyuhe, nibindi
Byongeye kandi, ku bavunitse nta ngamba zo gushinga voltage, inverter nazo zigomba kandi kuba zisohotse ingamba zo kurinda imizigo kugirango zirekurwe mubyangiritse birenze.
8. Gutangira ibiranga
Kuranga ubushobozi bwinzogera kugirango utangire numutwaro nigikorwa mugihe cyo gukora neza. Incumoko igomba kwizerwa gutangira kwizerwa mumutwaro.
9. Urusaku
Guhinduranya, kuyungurura amavuko, kuyungurura amashanyarazi, impinduka zamateka n'abafana mu mbaraga ibikoresho bya elegitoroniki byose bisa urusaku. Iyo inverter iri mubikorwa bisanzwe, urusaku rwarwo ntirugomba kurenga 80DB, kandi urusaku rwa ruto ruto ntirukwiye kurenga 65DB.
