Ma solar atha kupanga magetsi olumikizidwa mwachindunji ndi inverter

Mphamvu yopangidwa ndimapanelo a dzuwa ikhoza kulumikizidwa mwachindunji ndi inverter, yomwe ndi imodzi mwa njira zodziwika bwino za ma solar photovoltaic systems. Dzuwa, lomwe limadziwikanso kuti photovoltaic (PV) panel, ndi chipangizo chomwe chimasintha kuwala kwa dzuwa kukhala magetsi olunjika. Komabe, zida zambiri zamagetsi, kuphatikiza zida zapakhomo ndi ma mota am'mafakitale, nthawi zambiri amagwiritsa ntchito alternating current (AC). Chifukwa chake, kuti magetsi opangidwa ndi ma solar agwiritsidwe ntchito ndi zida izi, mphamvu ya DC iyenera kusinthidwa kukhala mphamvu ya ACinverter.

Momwe mungalumikizire ma solar panels ku inverter

Ma solar panel nthawi zambiri amalumikizidwa ndi inverter mu mndandanda kapena mofananira. Pakulumikizana kotsatizana, ma solar panels amalumikizidwa palimodzi kuti apange voteji yomwe ikufunika, pomwe ikulumikizana kofananira, ma solar amalumikizidwa palimodzi kuti apereke mulingo wofunikira wapano. Ma inverters amatha kukhala apakati, zingwe kapena ma micro-inverters kutengera zofunikira ndi kapangidwe kake.

1. Inverter yapakati: Yogwiritsidwa ntchito m'makina akuluakulu a photovoltaic, ma solar angapo amagwirizanitsidwa mndandanda ndi kufanana ndi kulowetsa kwa DC kwa inverter imodzi.
2. String inverter: Chingwe chilichonse cha solar panel chimadutsa pa inverter, yomwe imakulitsa magwiridwe antchito a chingwe cha photovoltaic ndikuwongolera magwiridwe antchito ndi kudalirika.
3. Microinverter: Gulu lililonse la solar kapena mapanelo angapo amalumikizidwa ku microinverter yosiyana, yomwe imatha kukwaniritsa kutsata kwamphamvu kwambiri (MPPT) pagawo lililonse ndikuwongolera magwiridwe antchito onse.

Momwe inverter imagwirira ntchito

Ntchito yayikulu ya inverter ndikusintha mphamvu ya DC kukhala mphamvu ya AC. Njirayi imaphatikizapo kugwiritsa ntchito zamagetsi zamagetsi, monga ma transistors ndi ma diode, kuti apange mawonekedwe osinthika apano kudzera pa pulse wide modulation (PWM) kapena njira zina zosinthira. Inverter ikhozanso kukhala ndi algorithm ya Maximum Power Point Tracking (MPPT) kuti muwonetsetse kuti ma solar akugwira ntchito nthawi zonse pamlingo wawo waukulu.

Inverter bwino ndi ntchito

Kuchita bwino kwa inverter ndiyeso yayikulu pakuchita kwake. Ma inverters apamwamba amatha kuchepetsa kutayika panthawi ya kutembenuka kwa mphamvu ndikuwonjezera mphamvu zonse za dongosolo. Kuchita bwino kwa inverter kumakhudzidwa ndi zinthu zambiri, kuphatikiza kapangidwe kake, mphamvu zamagetsi zomwe zimagwiritsidwa ntchito, kasamalidwe kamafuta ndi ma algorithms owongolera.

Malingaliro a Mapangidwe a System

Popanga solar photovoltaic system, zinthu zotsatirazi ziyenera kuganiziridwa:

1. Mphamvu zonse za solar panel: Izi zimatsimikizira kuchuluka kwa magetsi omwe dongosolo lingathe kupanga.
2. Kuthekera kwa inverter: The inverter iyenera kuthana ndi mphamvu yayikulu kwambiri yopangidwa ndi ma solar.
3. Chitetezo chadongosolo: Inverter iyenera kukhala ndi zochulukira, zozungulira zazifupi komanso zoteteza kutenthedwa.
4. Kugwirizana: The inverter iyenera kukhala yogwirizana ndi mapanelo a solar ndi grid system.
5. Kuyika ndi Kukonza: Inverter iyenera kukhazikitsidwa potsatira malangizo a wopanga ndikusungidwa pafupipafupi kuti zitsimikizire kuti dongosololi likuyenda bwino.

Chitetezo ndi kutsata

Makina a solar PV ndi ma inverters amayenera kupangidwa ndikuyikidwa motsatira ma code amagetsi am'deralo ndi miyezo yachitetezo. Ma inverters nthawi zambiri amafunikira kuti akhale ndi ziphaso zofunikira zachitetezo, monga IEC 62109-1 ndi IEC 62109-2.

Onetsetsani ndi kusunga

Ma inverters amakono nthawi zambiri amakhala ndi ntchito zowunikira zomwe zimatha kuyang'anira magwiridwe antchito munthawi yeniyeni, kuphatikiza kupanga magetsi, mawonekedwe a inverter ndi ma alarm. Izi zimathandiza oyendetsa makina kukhathamiritsa magwiridwe antchito ndikuyankha mwachangu pazovuta zilizonse.

Pomaliza

Makina opangira magetsi a solar panel amagwiritsa ntchito inverter kuti asinthe magetsi achindunji kukhala alternating current kuti agwiritse ntchito pa gridi yamagetsi kapena kuti agwiritse ntchito kunyumba. Kusankha inverter yoyenera ndikofunikira kuti muwonetsetse kuti dongosololi likuyenda bwino komanso kukulitsa kubweza ndalama. Mapangidwe a makina ayenera kuganizira za mtundu, mphamvu, chitetezo ndi zofunikira za inverter, pamene akutsatira malamulo ndi miyezo yoyenera.
