Sobanukirwa na sisitemu ya PV Sisitemu: Uruhare rwa Inverteri ninsinga mugukumira ikirwa

1. Fenomenon yo mu kirwa ni iki muri sisitemu ya PV ihujwe?

Ibisobanuro

Ikirwa kibaho kiboneka muri gride ihujwe na fotovoltaque (PV) mugihe gride ihuye numuriro w'amashanyarazi, ariko sisitemu ya PV ikomeje gutanga ingufu mumitwaro ihujwe. Ibi birema "ikirwa" cyaho cyo kubyara amashanyarazi.

Akaga kirwa

• Ibyago byumutekano: Ingaruka kubakozi bakora ibikorwa byo gusana gride.
• Kwangiza ibikoresho: Ibice byamashanyarazi birashobora gukora nabi kubera voltage idahindagurika hamwe ninshuro.
• Imiyoboro idahwitse: Ibirwa bitagenzuwe birashobora guhagarika imikorere ya gride nini.

2. Ibyingenzi byingenzi nibipimo byimiterere ihindagurika

Ibyingenzi byingenzi biranga Inverters

1. Kurinda Ibirwa: Koresha uburyo bukora kandi bworoshye bwo gutahura kugirango uhite uhagarika mugihe cyananiranye.
2. MPPT ikora neza (Gukurikirana imbaraga ntarengwa): Yongera imbaraga zo guhindura ingufu ziva kuri panne ya PV.
3. Gukora neza cyane: Mubisanzwe> 95% kugirango ugabanye igihombo cyingufu.
4. Itumanaho ryubwenge: Shyigikira protocole nka RS485, Wi-Fi, cyangwa Ethernet yo gukurikirana.
5. Ubuyobozi bwa kure: Emerera gukurikirana no kugenzura sisitemu kure.

Ibipimo byingenzi bya tekiniki

3. Guhuza Hagati ya PV Cable Guhitamo no Kurinda Ibirwa

Akamaro k'insinga za PV

Intsinga nziza ya PV ifite uruhare runini mukubungabunga umutekano no kugenzura neza imiterere ya gride, ningirakamaro muburyo bwo kurwanya ibirwa.

1. Gukwirakwiza Amashanyarazi neza: Kugabanya ibitonyanga bya voltage nigihombo cyingufu, kwemeza ingufu zihoraho muri inverter.
2. Ikimenyetso Cyukuri: Kugabanya urusaku rw'amashanyarazi no gutandukana, kunoza ubushobozi bwa inverter yo kumenya ibyananiranye.
3. Kuramba: Iremeza igihe kirekire kwizerwa mubihe bitandukanye bidukikije, ikomeza imikorere ihamye.

4. BasabweImiyoboro ya PV ya sisitemu ihujwe na sisitemu

Amahitamo ya PV yo hejuru

1. EN H1Z2Z2-K
   • Ibiranga: Umwotsi muke, halogene, irwanya ikirere kinini.
   • Kubahiriza: Yujuje ibipimo bya IEC 62930.
   • Porogaramu: Sisitemu ya PV yubatswe hejuru kandi hejuru yinzu.
2. TUV PV1-F
   • Ibiranga: Kurwanya ubushyuhe buhebuje (-40 ° C kugeza + 90 ° C).
   • Kubahiriza: Icyemezo cya TÜV kubipimo byumutekano muke.
   • Porogaramu: Ikwirakwizwa rya PV sisitemu na agrivoltaics.
3. Umugozi wa PV
   • Ibiranga: Kongera imbaraga zo gukingira no kuramba.
   • Kubahiriza: Yujuje IEC 62930 na EN 60228.
   • Porogaramu: Inganda zingana na PV sisitemu n'ibidukikije bikaze.

Imbonerahamwe yo Kugereranya

Danyang Winpower Wire na Cable Mfg Co, Ltd.

Uwakoze ibikoresho byamashanyarazi nibikoresho, ibicuruzwa byingenzi birimo insinga z'amashanyarazi, ibyuma bifata insinga hamwe na elegitoronike. Ikoreshwa muri sisitemu yo murugo ifite ubwenge, sisitemu yo gufotora, sisitemu yo kubika ingufu, hamwe na sisitemu yimodoka

Umwanzuro n'ibyifuzo

• Gusobanukirwa Ikirwa: Ibirwa bitera ingaruka zikomeye kumutekano, ibikoresho, hamwe na gride itajegajega, bisaba ingamba zifatika zo gukumira.
• Guhitamo Inverteri iburyo: Hitamo inverter zifite uburinzi bwo kurwanya ikirwa, gukora neza, hamwe nubushobozi bukomeye bwo gutumanaho.
• Gushyira imbere insinga nziza: Hitamo insinga za PV hamwe nigihe kirekire, impedance nkeya, nibikorwa byizewe kugirango sisitemu ihamye.
• Kubungabunga buri gihe: Kugenzura ibihe bya sisitemu ya PV, harimo inverteri ninsinga, nibyingenzi kubwizerwa burigihe.

Muguhitamo neza ibice bikwiye no kubungabunga sisitemu, imiyoboro ya PV ihujwe na grid irashobora kugera kumikorere myiza numutekano mugihe yubahiriza ibipimo byinganda.
