Monga katswiri wamkulu muzolumikizira PV yosungirako inverters, Amass imayang'anira msika ndi zosowa za makasitomala, ndipo mosalekeza kulimbikitsa kafukufuku wazinthu ndi chitukuko ndi luso laukadaulo. Kupititsa patsogolo mlingo wa utumiki, kupereka makasitomala ndi kothandiza, otetezeka, makonda njira lifiyamu-ion ntchito kugwirizana ntchito, mu makampani Takhala kutamandidwa mu makampani.
Chikalata chaposachedwa cha heavyweight "Chidziwitso Cholimbikitsa Mabizinesi Opangira Mphamvu Zowonjezedwanso Kuti Amange kapena Kugula Kutha Kwambiri Kuti Achulukitse Sikelo ya Kuphatikizana kwa Gridi" ikufuna kuwonjezereka kwa kuphatikizika kwa gridi yamagetsi ongowonjezedwanso.
Ngakhale kuti palibe kutchula mwachindunji kusungirako mphamvu, koma msika wakhala ukuwona kusungirako mphamvu ngati chinthu chabwino kwambiri.
Chifukwa cha kusinthasintha kwachilengedwe kwa kuwala ndi mphepo, zomwe zimapangitsa kuti pakhale mphamvu yosasunthika, mphamvu ya photovoltaic ndi mphepo yamkuntho sichitha nthawi zonse kukwaniritsa zofunikira za gridi, ndiko kuti, kuwala kosiyidwa ndi mphepo. Izi ndizongotaya. Ngati mphamvu zowonongekazi zikhoza kusungidwa, ndiye kuti mtengo wopangira mphamvu zowonjezera udzapitirira kuchepa. Ndipo ichi ndi chifukwa chake kuphulika kwa likulu la kusunga mphamvu.
Pambuyo pofotokoza mbali zonse, ndikofunikira kuyang'ana gawolo ndi mphamvu yamphamvu kwambiri yophulika.
Ngati titsatira izi, ndiye kuti inverter ndi dzanja losankha mbewu.
Mfundo yochititsa zimenezi si yovuta kwenikweni kuimvetsa. Mu dongosolo la PV, inverter imagwira ntchito yofunikira monga kutembenuka kwa AC/DC, kuwongolera mphamvu, ndi kusinthana kofanana/kuchoka pa gridi. Ndipo mu inverter, magawo ake ocheperako inverter cholumikizira magwiridwe antchito amafunikanso kulabadira.
Popanda kuthandizidwa ndi mphamvu yosungirako mphamvu, magetsi opangidwa ndi PV amalumikizidwa mwachindunji ndi gridi kudzera mu inverter. Ndi kusungirako mphamvu, magetsi opangidwa ndi PV amayamba kusungidwa muzosungirako kudzera mu inverter, ndiyeno magetsi amagwirizanitsidwa ndi gridi kudzera mu inverter. Ngakhale pali kutembenuka kwina kwina, koma kudzatha kupulumutsa magetsi otayika (kuwala kosiyidwa), motero kukulitsa nthawi yogwiritsira ntchito PV.
Kukula kwa kufunikira kwa ma inverters sikungapeweke. Malinga ndi zoneneratu za kafukufuku wofananira, inverter yapadziko lonse ya PV yosungira mphamvu yofananira ndi mphamvu yoyika mpaka 104GW mu 2025, pomwe mphamvu yoyika padziko lonse lapansi mu 2020 inali 5.3GW yokha. ndiko kuti, ka 20 m’zaka 5, ndi chiwonjezeko chokulirapo pachaka choposa 80%.
Mwina anthu ena anganene kuti, mphamvu zatsopano zigawo zonse, kufunikira kukukulirakulira, ndiye kuti kuchuluka kwa inverter kuli kuti?
Mwachidule, ma inverters ali ndi malingaliro ogwiritsira ntchito. Kutalika kwa moyo wa chomera chachikulu cha PV chokwera pansi nthawi zambiri kumakhala zaka 20. Inverter imachepetsedwa ndi zida zamkati zamagetsi (IGBT, capacitors, inductors, etc.), moyo wautumiki nthawi zambiri siwopitilira zaka 10. M'mawu ena, PV mphamvu chomera
Mwanjira ina, chomera cha PV chimafunikira ma inverters 2 pa moyo wake wonse. Izi zimabweretsa kufunikira kwa inverter kupindula osati kungowonjezera PV, komanso ndi katundu. Kuchuluka kwa kufunikira kwa mtsinje nthawi zambiri kumabweretsa kukwera kwamitengo yazinthu zakumtunda. Pokhapokha, chidwi chachikulu pamakampani a inverter sikukwera kwamitengo, koma mawonekedwe amakampani pagawo loperekera. Chifukwa chomwe simukuyenera kuyembekezera kukwera kwamitengo, chifukwa ma inverters ali ndi zotchinga zonse zaukadaulo, komanso kutchula mtengo wotsika. Kwa ma inverters a photovoltaic, mwachitsanzo, 1 inverter yolumikizidwa ndi zidutswa khumi ndi ziwiri za ma modules a photovoltaic, inverters kamodzi kokha vuto, dongosolo lonse lidzakhala lopuwala. Kugogomezera chitetezo, kupanga ma inverters oyambirira amapangidwa ku Germany. Komabe, pokhudzana ndi mndandanda wonse wamakampani a PV, inverter ndiye gawo lotsika kwambiri lazachuma, ntchito yowunikira kwambiri ya ulalo, ndipo izi zimaperekanso kubisala kotsika mtengo.
Inverter yolumikizidwa ndi zidutswa khumi ndi ziwiri za ma module a photovoltaic, momwe ma terminals a photovoltaic inverter DC ndi ofunikira, nthawi yomweyo monga zigawo zazikulu zolumikizira, kamodzi kokha ubwino wa mavuto ake, komanso zosavuta kwambiri kuti zitsogolere ziwalo za dongosolo lonse yosungirako mphamvu!
Opanga zapakhomo kenako anapowolera mwa zenera luso, ndipo anatenga mzimu wa ntchito yaikulu, mwamsanga kufalitsa mphamvu kupanga (ukonde chuma ntchito ya makampani, kukula mphamvu ndi mofulumira), ndi khalidwe labwino ndi otsika mtengo mankhwala, kulanda gawo msika pa nthawi yomweyo, komanso inverter mu photovoltaic system.Total mtengo wa umwini wosakwana 10%. Opanga apakhomo amagulitsa zinthu zakunja, zapakati komanso zapakhomo zogulitsira zida za 0,25 yuan / W ndi 0.5 yuan / W, zotsika kwambiri kuposa mabizinesi akunja 0,57 yuan / W ndi 0,78 yuan / W mtengo wogulitsa.
Kuphatikiza pakuwonjezeka kwamitengo sikukomera mawonekedwe amakampaniwo, padzakhala chiwopsezo chakugwa ndi makasitomala. Masiku ano, chinthu choyipa kwambiri pamakampani a PV ndi ma cell otsika komanso opanga ma module. Kumtunda omwe amayesa kukweza mitengo, adzagwirizana ndi nyundo yemwe - mtengo ukuwonjezeka koma unkayang'ana pa silicon, galasi la photovoltaic ndi chitsanzo. Monga katswiri pa zotsika mtengozolumikizira zosungira mphamvu, Amass amatenga njira yopangira mgwirizano wamakasitomala ambiri, omwe amatsimikizira kuti zinthu zili bwino komanso zimachepetsa mtengo wake nthawi imodzi, ndikusunga mtengo kwa makasitomala ambiri. Mkhalidwe wabwino kwambiri ndi kupambana-kupambana. Kupambana-kupambana kokha kungatsimikizire chitukuko chokhazikika. Mwa njira iyi, zikuwoneka kuti chitsanzo chabwino cha mafakitale ndi nkhuku yomwe imayika mazira a golide m'manja mwa makampani a inverter.
