1.Njodzi dzakavanzwa dziri shure kweindasitiri ye photovoltaic iri kukura

Mumakore achangopfuura, musika wepasi rose we photovoltaic wave kukura zvinoshamisa, se rocket. Ndichiri kuyeuka pandakapinda kuratidzwa kwesimba rezuva kuGermany makore mashanu apfuura, simba guru re module raive panosvika 300W. Iye zvino, hazvishamisi kuona 600W+ bifacial modules. Zvisinei, pakati pekukura uku kwekuisa, nyaya yakakosha inowanzo furatirwa - kuchengetedzwa kwesystem.

Gore rapera, kambani yedu yakabata nyaya yakabva kuTurkey: chiteshi chemagetsi che5MW chakaiswa pasi. Mwedzi mitatu mushure mekunge chabatanidzwa negrid, ma inverter mana akatsva akatevedzana. Munguva yekuferefeta panzvimbo iyi, zvakaonekwa kuti muridzi wacho akachengetedza mari nekusiya zvishandiso zvekudzivirira surge kudivi reDC. Kurasikirwa kwekupedzisira kwaive kwakakura kusvika kumadhora ekuAmerica anodarika 200,000, izvo zvaikwana kutenga mazana eSPDs epamusoro-soro. Zvidzidzo zvakadaro hazviwanzoitika muindasitiri iyi.

2."Vaurayi vemagetsi" vakatarisana nemasisitimu emagetsi ezuva nezuva

2.1Kurohwa nemheni: njodzi ine njodzi zvikuru

Ndakasangana nechirongwa chekubatsirana nemwaranzi yekubata hove muHainan. Dunhu iri rine mazuva anopfuura makumi mapfumbamwe emvura inonaya gore rega rega. Mutariri wavo wekushanda akandiudza kuti vasati vaisa SPD, vaigara vakaneta munguva yemvura inonaya gore rega rega. Chiitiko chakakomba ndechekuti mheni yakarova yakaita kuti ma inverter ese emhando ye string-type ari mu array yese "arove" pamwe chete.

Zvinofadza kuti vanhu vazhinji vanofunga kuti kurova mheni zvakananga chete kune njodzi. Kutaura zvazviri, data redu rekuona rinoratidza kuti kurova mheni mukati memakiromita matatu kunogona kukonzera kukwira kwakasimba kwakakwana kwekukuvadza michina. Paimbova nepurojekiti yekuBrazil uko nzvimbo yekurova mheni yaive papurazi riri pedyo, asi zvakaita kuti ma module ese ekutarisa e photovoltaic system akundikana.

2.2Kuchinja-chinja kweGrid: Muurayi Asingaonekwe

Patakange tichibatanidzwa mukutanga kwepurojekiti yedenga remba muVietnam gore rapera, takanyora data rinoshamisa: Kuchinja-chinja kwemagetsi emagetsi emunharaunda panguva yekushandiswa kwemagetsi zvakanyanya kwaiwanzopfuura 15%. Kukanganiswa kwemagetsi uku kunokuvadza hupenyu hwemidziyo kupfuura kukwira kwemagetsi ipapo ipapo.

Dambudziko guru rinonetsa isimba remagetsi rinogadzirwa ne photovoltaic system pachayo. Yeuka, pane imwe nguva payakaedza imwe mhando ye inverter, simba remagetsi raiburitsa panguva yekudzima raipeta kane kana kupfuura simba remagetsi rakarongwa! Rudzi urwu rwe "simba remagetsi rinozvigadzira uye rinozvidya" chinhu chisingaonekwe nevaridzi vedzimba vazhinji.

3.SPD inodzivirira sei system ye photovoltaic?

3.1Dziviriro ine mativi akawanda: Pfeka "jira rinodzivirira mabara" rehurongwa

Sistimu yakanaka yekudzivirira inofanira kunge yakaita sehanyanisi ine dziviriro yakawanda. Tinowanzo kurudzira vatengi kuti vashandisenzira yekudzivirira ine nhanho nhatu:

Chikamu cheArray:Isa Type 2 SPD pabhokisi rekubatanidza kuti udzivirire kubva kumhashu dzinokonzereswa nemagetsi.

Danho reInverter: Shandisa SPD ye photovoltaic yakatsaurirwa kudivi reDC input. Nyatsoteerera kusarudzwa kwevoltage yeUc.

Nzvimbo yekubatanidza grid:Isa SPD yakagadzirirwa grid yemuno kudivi reAC.

3.2Kusanzwisisana kweSarudzo: Kana parameter yakakwira, zviri nani

Zvinowanzoonekwa kuti vatengi vanotevera zvisina kujeka maImax values. Kutaura zvazviri, kumapurojekiti mazhinji akapararira, 20kA discharge capacity yakakwana. Chinhu chikuru chiri mu:

- Kugona kufananidza voltage (Uc ≥ 1.2 × Maximum system voltage)

- Simba remagetsi rasara (Izvi zvakakosha sezvo zvichiratidza kana michina ichigona kuchengetedzwa zvechokwadi)

- Basa rekuratidza kuora (Izvi zvakakosha zvikuru sezvo zvichigona kudzivirira "zombie SPD")

Mutengi wekuAustralia akasimbirira pakuisa SPD ine chiyero che40kA. Zvisinei, nekuda kwesarudzo yevoltage yakaderera yeUc, SPD yakakwegura nguva isati yakwana kana sisitimu yacho yave pasi pemutoro wakareruka.

3.3Usarega zvikanganiso zvekudzivirira zvichikanganisa mari inodyarwa

Ndakaona varidzi vedzimba vakawanda vakangwarira vanoda kushandisa mari yakawanda pazvinhu zvepamusoro asi vachinyanya kungwarira nezvekuchengetedza sisitimu. Kutaura zvazviri, mhinduro yeSPD (Surge Protective Device) yakagadzirwa zvakanaka inowanzoita 0.3% kusvika 0.5% yemari yese yepurojekiti, asi inogona kudzivirira kupfuura 80% yekukundikana kwemagetsi.

Zvinokurudzirwa kuti munhu wese afunge nezve zvinotevera panguva yekugadzira:

- Ruzivo rwemunharaunda nezvemazuva emvura ine dutu (runogona kuwanikwa zviri nyore kubva kuhofisi yemamiriro ekunze)

- Mishumo yemhando yegrid

- Mitemo yekushivirira kukwira kwemvura yakaiswa nevagadziri vemidziyo

Mhedziso

Kuti system ye photovoltaic ishande zvakanaka kwemakore makumi maviri nemashanu, inoda dziviriro yakavimbika ye surge. Zvakafanana nekushanda panzvimbo dzakakwirira usina kupfeka bhandi rekuchengetedza - pamwe unogona kuramba wakachengeteka kekutanga ka99, asi kechi100 kunogona kukudhura zvakanyanya.
