Nigute Washyiraho Anti-Reverse (Zeru-Kohereza) Ibipimo by'ingufu muri sisitemu ya PV - Ubuyobozi bwuzuye

Intangiriro

Nkuko kwifotoza (PV) kwihuta, imishinga myinshi irahurazeru-byohereza hanze. Ibikorwa bikunze kubuza ingufu z'izuba zirenze gusubira muri gride, cyane cyane mubice bifite transformateur zuzuye, uburenganzira budasobanutse bwuburenganzira bwo guhuza imiyoboro, cyangwa amategeko akomeye yubuziranenge. Aka gatabo gasobanura uburyo bwo kwishyirirahoanti-revers (zeru-yohereza) metero z'amashanyarazi, ibisubizo byibanze birahari, hamwe nuburyo bukwiye bwa sisitemu ya PV itandukanye.

1. Ibitekerezo byingenzi mbere yo kwishyiriraho

Ibiteganijwe gutegekwa kuri Zeru-Kohereza

  • Kwiyuzuza: Iyo transformateur zaho zimaze gukora mubushobozi buhanitse, imbaraga zinyuranye zishobora gutera kurenza urugero, kugendagenda, cyangwa ibikoresho byananiranye.

  • Kwikoresha wenyine (nta gride yohereza ibicuruzwa byemewe): Imishinga idafite gride yo kugaburira ibyemezo igomba gukoresha ingufu zose zabyaye mugace.

  • Kurinda ubuziranenge bw'ingufu: Imbaraga zinyuranye zishobora kumenyekanisha ibice bya DC, guhuza, cyangwa imizigo idahwitse, kugabanya ubuziranenge bwa gride.

Urutonde rwibanze

  • Guhuza ibikoresho: Menya neza ko metero yapimwe ubushobozi bwa metero ihuye nubunini bwa sisitemu ya PV (icyiciro kimwe ≤8kW, ibyiciro bitatu> 8kW). Reba itumanaho rya inverter (RS485 cyangwa ibisa nayo).

  • Ibidukikije: Kubikoresho byo hanze, tegura ibirindiro bitarinda ikirere. Kuri sisitemu nyinshi-inverter, tegura RS485 wiring ya bisi cyangwa Ethernet yibanda kuri data.

  • Kubahiriza n'umutekano: Emeza grid ihuza ingingo hamwe ningirakamaro, hanyuma urebe ko urwego rwimitwaro ihuye nibiteganijwe kuri PV.

2. Core Zero-Kohereza Ibisubizo

Igisubizo 1: Kugabanya imbaraga ukoresheje Igenzura rya Inverter

  • Ihame: Imashini yubwenge ipima icyerekezo nyacyo cyerekezo. Iyo hagaragaye imigendekere yinyuma, metero ivugana na RS485 (cyangwa izindi protocole) hamwe na inverter, igabanya imbaraga zayo zisohoka kugeza kohereza hanze = 0.

  • Koresha imanza: Guhindura uduce twuzuye, imishinga yo kwikorera hamwe n'imitwaro ihamye.

  • Ibyiza: Byoroshye, bidahenze, igisubizo cyihuse, ntabwo bikenewe kubika.

Igisubizo 2: Kuramo Absorption cyangwa Kwibika Ingufu

  • Ihame: Metero ikurikirana ikigezweho kuri gride ihuza. Aho kugabanya umusaruro wa inverter, imbaraga zirenze urugero zerekeza muri sisitemu yo kubika cyangwa guta imizigo (urugero, ubushyuhe, ibikoresho byinganda).

  • Koresha imanza: Imishinga ifite imitwaro ihindagurika cyane, cyangwa aho kugwiza ibisekuru bya PV nibyingenzi.

  • Ibyiza: Inverters iguma muburyo bwa MPPT, ingufu ntizipfusha ubusa, sisitemu yo hejuru ROI.

3. Kwerekana ibintu byubunini bwa sisitemu

Sisitemu imwe imwe (≤100 kWt)

  • Iboneza: 1 inverter + 1 metero yubwenge ya metero ebyiri.

  • Umwanya wa metero: Hagati ya inverter AC isohoka na breaker nyamukuru. Ntayindi mitwaro igomba guhuzwa hagati.

  • Urutonde.

  • Birumvikana: Metero ipima icyerekezo n'imbaraga, hanyuma inverter ihindura ibisohoka kugirango ihuze umutwaro.

  • Inyungu: Gukoresha byoroshye, igiciro gito, igisubizo cyihuse.

Sisitemu nyinshi-Inverter Sisitemu (> 100 kWt)

  • Iboneza: Inverters nyinshi + 1 metero yububasha bwimbaraga + 1 yibanze kuri data.

  • Umwanya wa metero: Kuri gride ihuriweho hamwe (ibisubizo byose byahinduwe).

  • Wiring.

  • Birumvikana: Ikusanyamakuru ryegeranya metero yamakuru kandi ikwirakwiza amategeko kuri buri inverter ugereranije.

  • Inyungu: Igipimo kinini, gishyizwe hamwe, igenamiterere ryoroshye.

4. Kwishyiriraho muburyo butandukanye bwimishinga

Kwikoresha wenyine Imishinga

  • Ibisabwa: Nta gride yohereza ibicuruzwa byemewe.

  • Umwanya wa metero: Hagati ya inverter AC isohoka hamwe nuwamennye imitwaro yaho. Nta gride ihuza imiyoboro ikoreshwa.

  • Reba: Gerageza munsi yisekuru yuzuye nta mutwaro - inverter igomba kugabanya imbaraga kuri zeru.

Imishinga yo Kwuzuza Impinduka

  • Ibisabwa: Imiyoboro ya gride iremewe, ariko imbaraga zinyuranye zirabujijwe rwose.

  • Umwanya wa metero: Hagati ya inverter isohoka na gride ihuza breaker.

  • Birumvikana: Niba imbaraga zinyuranye zagaragaye, inverter igabanya ibisohoka; nkibikubiyemo, abamena barashobora gutandukana kugirango birinde guhangayika.

Gakondo-Kwikoresha + Imishinga yohereza ibicuruzwa hanze

  • Ibisabwa: Kohereza ibicuruzwa byemewe, ariko bigarukira.

  • Gushiraho metero: Anti-revers ya metero yashyizwe murukurikirane hamwe na metero ya fagitire yingirakamaro.

  • Birumvikana: Metero anti-reverse ibuza kohereza hanze; gusa mugihe byananiranye gukora metero yingirakamaro yandika kugaburira.

5. Ibibazo

Q1: Ese metero ubwayo ihagarika gusubira inyuma?
Oya. Imetero ipima icyerekezo cy'amashanyarazi ikabimenyesha. Inverter cyangwa umugenzuzi akora ibikorwa.

Q2: Sisitemu ishobora kwihuta gute?
Mubisanzwe mumasegonda 1-2, bitewe numuvuduko witumanaho hamwe na software ya inverter.

Q3: Bigenda bite mugihe cyo kunanirwa kwurusobe?
Itumanaho ryaho (RS485 cyangwa igenzura ritaziguye) rituma hakomeza kurindwa nubwo nta interineti.

Q4: Izi metero zishobora gukora muri sisitemu yo gucamo ibice (120 / 240V)?
Nibyo, moderi zimwe zagenewe gukemura ibice-ibice byakoreshejwe muri Amerika ya ruguru.

Umwanzuro

Zeru-yoherezwa mu mahanga ihinduka itegeko mu mishinga myinshi ya PV. Mugushiraho anti-revers yububasha bwimbaraga za metero ahantu heza kandi ukabihuza na inverter, imizigo yataye, cyangwa ububiko,EPC, abashoramari, nabateza imbereIrashobora gutanga sisitemu yizewe, yubahiriza-izuba. Ibi bisubizo ntabwo byonyinekurinda urusobeariko nanonekugwiza cyane kwikoresha na ROIkubakoresha-nyuma.
