2017 imadziwika kuti ndi chaka choyamba cha anagawira PHOTOVOLTAIC wa China, kuwonjezeka pachaka anagawira PV anaika mphamvu pafupifupi 20GW, zikuoneka kuti banja anagawira PV chawonjezeka ndi mabanja oposa 500,000, amene Zhejiang, Shandong zigawo ziwiri za Kukhazikitsa kwa PV m'nyumba kuli mabanja opitilira 100,000.
Monga amadziwika kwa onse, poyerekeza ndi siteshoni yaikulu mphamvu pansi, chilengedwe cha denga anagawira siteshoni mphamvu photovoltaic ndi zovuta kwambiri, pofuna kupewa chikoka cha zopinga monga kampanda, nyumba zozungulira, zingwe pamwamba, chimney padenga, dzuwa. chotenthetsera madzi, ndi kupewa vuto la kusiyana kwa denga kuyatsa sikukugwirizana, kupezeka denga kukhazikitsa malo adzachepetsedwa ndipo anaika mphamvu adzakhala ochepa.
Ngati gawo ili lachitetezo silingapewedwe, siteshoni yamagetsi idzayambitsa kusagwirizana kwa mndandanda ndi kufanana chifukwa cha chishango kapena kuyatsa kosagwirizana, ndipo mphamvu zonse zopangira magetsi pamalopo zidzachepetsedwa.Malinga ndi malipoti ofunikira ofufuza, mthunzi wam'deralo wa ma module a photovoltaic udzatsitsa mndandanda wonse wamagetsi opangira mphamvu kuposa 30%.
Malingana ndi kusanthula kwa PVsyst modelling, chifukwa cha makhalidwe a photovoltaic series, ngati mphamvu yopangira gawo limodzi la photovoltaic imachepetsedwa ndi 30%, mphamvu zowonjezera zigawo zina mu gulu lonse zidzagweranso pamtunda womwewo. ndi zotsatira za bolodi lalifupi la mbiya yamatabwa mu dongosolo la gulu la photovoltaic.
Poganizira zomwe zili pamwambazi, tikulimbikitsidwa kukhazikitsa PV mphamvu optimizer, yomwe imatha kulamulira kuthamanga ndi kugwa kwa gawo lililonse la PV, kuthetsa mavuto a mndandanda ndi kufanana kwa magulu a photovoltaic chifukwa cha ming'alu yobisika, malo otentha, kutsekeka kwa mthunzi, ukhondo wosiyanasiyana, mawonekedwe osagwirizana ndi kuunikira, ndipo zitha kupititsa patsogolo mphamvu zonse zamagetsi.
Milandu itatu idagwiritsidwa ntchito kuyesa mphamvu ya photovoltaic power optimizer.
8KW padenga lamagetsi, mphamvu yopangira malo okhathamiritsa idakwera ndi 130%, imapanga magetsi owonjezera 6 KWH tsiku lililonse.
Malo opangira magetsi apanyumba a 8KW amamangidwa pansanjika yachitatu ya nyumbayo.Zigawo zina zimayikidwa pa khonde la khonde ndipo zina zimayikidwa pamtunda wa matailosi.
Battery module imayikidwa pamthunzi ndi chowotcha chamadzi ndi nsanja yamadzi yoyandikana nayo, yomwe imatsatiridwa ndi PVsyst kwa miyezi 12 ya chaka.Zotsatira zake, zimapanga magetsi ochepera 63% kuposa momwe ziyenera kukhalira, 8.3 KWH patsiku,
Chowonjezeracho chikayikiridwa pamndandandawu, poyerekeza mphamvu zamagetsi m'masiku 10 adzuwa asanayambe komanso atatha kuyika, kusanthula kuli motere:
Tsiku loyamba la ntchito optimizer anali December 20, pa nthawi yomweyo, imvi gawo la mphamvu kuyerekeza gulu anawonjezera kusanthula kusaganizira chikoka cha ma radiation, kutentha ndi zosokoneza zina.Pambuyo pa kukhazikitsidwa kwa optimizer, mphamvu yowonjezera mphamvu ndi 130%, ndipo mphamvu yowonjezera tsiku ndi tsiku ndi 6 KWH.
Malo opangira magetsi padenga la 5.5KW, kupanga magetsi kwamagulu okhathamiritsa kudakwera ndi 39.13%, kumapanga magetsi owonjezera a 6.47 KWH tsiku lililonse.
Pamalo opangira magetsi padenga la 5.5kW omwe ayamba kugwira ntchito mu 2017, zingwe zonse ziwiri zimakhudzidwa ndi malo okhala mitengo yozungulira, ndipo mphamvu zopangira magetsi ndizotsika kuposa momwe zimakhalira.
Malinga ndi momwe chitetezo chimakhalira pamalopo, kutengera ndi kusanthula kumachitika mu pvsyst.Zingwe ziwirizi zili ndi ma modules a 20 photovoltaic, omwe adzakhala mthunzi kwa miyezi 10 ya chaka, kuchepetsa kwambiri mphamvu zonse zopangira magetsi.Kufotokozera mwachidule, photovoltaic power optimizer imayikidwa pamagulu awiri a ma modules 20 pa malo a polojekiti.
Pambuyo pa 20 photovoltaic optimizers power optimizers aikidwa pa zingwe ziwirizi, poyerekezera mphamvu zamagetsi m'masiku 5 adzuwa asanayambe komanso atatha kuyika, kusanthula kuli motere:
Tsiku loyamba la ntchito optimizer anali December 30, pa nthawi yomweyo, imvi gawo la mphamvu kuyerekeza gulu anawonjezera kusanthula kusaganizira chikoka cha ma radiation, kutentha ndi zosokoneza zina.Pambuyo pa kukhazikitsidwa kwa optimizer, mphamvu yowonjezera mphamvu ndi 39.13%, ndipo mphamvu yowonjezera tsiku ndi tsiku ndi 6.47 KWH.
2MW centralized power station, mphamvu zopangira magulu anayi m'dera la kukhathamiritsa zikuwonjezeka ndi 105.93%, zomwe zimapangidwa ndi 29,28 KWH zamagetsi tsiku lililonse.
Kwa 2MW centralized mountain power station yomwe idayamba kugwira ntchito mu 2015, malo otetezera mthunzi ndi ovuta kwambiri, omwe amagawidwa m'magawo atatu: chitetezo champhamvu, kutchingira mitengo ndi malo ochepa kwambiri a kutsogolo ndi kumbuyo kwa zigawo.Kutsogolo ndi kumbuyo kutchinga kwa zigawo kumawonekera m'nyengo yozizira chifukwa kutalika kwa dzuwa kumakhala kotsika, koma osati m'chilimwe.Kuthirira kwa mitengo ndi mitengo kumachitika chaka chonse.
Chitsanzo cha dongosolo lonse chimakhazikitsidwa mu pvsyst molingana ndi magawo a chitsanzo cha zigawo ndi ma inverters mu dongosolo, malo a polojekiti ndi momwe zimakhalira shaded.M'masiku adzuwa, kutayika kofananira kwa ma radiation ndi 8.9%.Phindu lachidziwitso silingapezeke chifukwa cha kutayika kwa magetsi osagwirizana chifukwa cha kusagwirizana.
Malingana ndi malo a malo, zingwe zinayi zimasankhidwa, 22 photovoltaic power optimizers imayikidwa mu chingwe chilichonse, ndipo chiwerengero cha 88 optimizers chimayikidwa.Poyerekeza kupanga magetsi asanayambe komanso atatha kuyika komanso kupanga magetsi a zingwe zoyandikana zomwe sizinayikidwe, kusanthula kuli motere:
M'masiku adzuwa, kusokonezeka kwa kuwala kwanyengo kuyenera kuchepetsedwa, ndipo gawo la imvi la kufananitsa gulu lamagulu liyenera kuonjezedwa kuti liwunikire kuti lithetse chikoka cha kuchuluka kwa ma radiation, kutentha ndi kusokoneza kwina.Pambuyo pa kukhazikitsidwa kwa optimizer, magetsi opangira magetsi ndi 105.93% apamwamba kuposa nthawi yomwe sichinakhazikitsidwe, mphamvu yowonjezera mphamvu pa chingwe patsiku imawonjezeka ndi 7.32 KWH, ndipo mphamvu yopangira zingwe zinayi wasintha mpaka +29.28 KWH.
Chifukwa cha kuchepetsedwa kwa malo akuluakulu opangira magetsi opangira magetsi komanso zovuta zazinthu ndi chilengedwe monga mapiri, tikulimbikitsidwa kuti anthu ambiri agwiritse ntchito denga kuti akhazikitse dongosolo la photovoltaic.Tidzapereka dongosolo lathunthu la kukhazikitsa dongosolo ndi dongosolo lotsatira loyeretsa solar.Tidzadzipereka nthawi zonse kupatsa ogwiritsa ntchito mphamvu zotetezeka, zokhazikika komanso zodalirika za photovoltaic.
