Umqondo ojwayelekile

Ukufeza ukusebenza okuphelele kwesikhungo samandla se-photovoltaic (PV), noma ngabe sincane, esifakwe ophahleni lwendlu yomndeni noma enkulu, eselulela ezindaweni ezinkulu, kuyadingeka ukwenza iphrojekthi eyinkimbinkimbi. Le phrojekthi ifaka phakathi ukukhethwa okulungile kwamapaneli e-PV nezinye izinto ezinjengokwakhiwa kwemishini, isistimu enhle yezintambo (indawo efanelekile yezakhi, ukwengamela okulungile kwekhebula, ukuxhumana okuvikelayo noma ukuvikelwa kwenethiwekhi) kanye nokuvikelwa kwangaphandle nangaphakathi kumbani nasekuvutheni kwamandla. Inkampani ye-LSP inikela ngamadivayisi wokuvikela ukuqhuma (i-SPD), angavikela utshalomali lwakho ngenani lezindleko zokuthenga eziphelele. Ngaphambi kokuphrojusa amadivayisi wokuvikela ukuqhuma, kuyadingeka ukuthi ujwayelane namaphaneli we-photovoltaic athile nokuxhumeka kwawo. Lolu lwazi luhlinzeka ngemininingwane eyisisekelo yokukhethwa kwe-SPD. Kuphathelene namandla aphezulu wesifunda avulekile wepaneli le-PV noma intambo (uchungechunge lwamapaneli axhunywe ochungechungeni). Ukuxhuma kwamapaneli e-PV ochungechungeni kukhulisa inani lamandla kagesi e-DC, abese eguqulwa abe ngama-voltage ka-AC kuma-inverters. Izicelo ezinkulu zingafinyelela ngokujwayelekile ku-1000 V DC. I-voltage yesekethe evulekile yephaneli le-PV inqunywa ngamandla emisebe yelanga ewela kumaseli ephaneli kanye nethempelesha. Ikhuphuka ngemisebe ekhulayo, kepha yehla ngokushisa okukhulayo.

Esinye isici esibalulekile sihilela ukufaka uhlelo lwangaphandle lokuvikela umbani - induku yombani. I-CSN EN 62305 ed.2 ejwayelekile yokuvikelwa kombani, Ingxenye 1 kuye ku-4 ichaza izinhlobo zokulahleka, izingozi, amasistimu wokuvikela umbani, amazinga okuvikela umbani nebanga elanele lokulinganisa. La mazinga amane okuvikelwa kombani (I kuya ku-IV) anquma imingcele yeziteleka zombani futhi ukuzimisela kunikezwa yizinga lobungozi.

Ngokomthetho, kunezimo ezimbili. Esimweni sokuqala, ukuvikelwa kwento ngohlelo lwangaphandle lokuvikela umbani kuyadingeka, kepha ibanga lokugoba (isb. Ibanga eliphakathi kwenethiwekhi yokuqeda umoya nohlelo lwe-PV) alinakugcinwa. Ngaphansi kwalezi zimo, kubalulekile ukuqinisekisa ukuxhumana kwe-galvanic phakathi kwenethiwekhi yokuqeda umoya kanye nesakhiwo sokusekela samaphaneli we-PV noma amafreyimu wephaneli le-PV. Umbani uhambisa u-I_imp (umfutho wamanje ngepharamitha ka-10/350 μs) bayakwazi ukungena kumasekethe e-DC; ngakho-ke kuyadingeka ukufaka uhlobo lokuvikela lwedivayisi yokuvikela uhlobo. I-LSP inikeza isisombululo esifaneleke kakhulu ngohlobo lwamadivayisi wokuvikela uhlobo oluhlanganisiwe lwe-1 + 1 FLP2-PV chungechunge, akhiqizelwa i-voltage ka-7 V, 600 V no-800 V noma nge-signization eyihlane noma ngaphandle. Esimweni sesibili, asikho isidingo sokuhlomisa into evikelwe ngohlelo lwangaphandle lokuvikela umbani, noma ibanga lokugoqa lingagcinwa. Kulesi simo, imisinga yombani ayikwazi ukungena kusifunda se-DC futhi kubhekwa kuphela i-overvoltage ebangelwa (impulse current nepharamitha ye-1000/8 μs), lapho uhlobo lwentambo yokuvikela ukuqhuma 20 lwanele, isb SLP2-PV series, ekhiqizwa i-voltage ka-40 V, 600 V, no-800 V, futhi nge-signization eyihlane noma ngaphandle kwayo.

Lapho sifaka amadivayisi wokuvikela ukuqhuma, kufanele sicabangele uhlangothi lwe-AC kanye nolayini nezindlela zokuxhumana, ezisetshenziswa ngokujwayelekile esiteshini samanje se-PV. Isiteshi samandla se-PV naso sisongelwa ngasohlangothini lwenethiwekhi ye-DC (distribution). Ngakolunye uhlangothi, ukukhethwa kwe-SPD efanelekile kubanzi kakhulu futhi kuya ngohlelo olunikeziwe. Njengomvikeli wokwanda komhlaba wonke, sincoma idivaysi yesimanje yochungechunge lwe-FLP25GR, efaka zonke izinhlobo ezintathu ze-1 + 2 + 3 ngaphakathi kwamamitha amahlanu ukusuka endaweni yokufaka. Ifaka inhlanganisela yama-varistor kanye nesiboshwa sombani. I-LSP inikeza uchungechunge oluningi lwamadivayisi wokuvikela ukukhuphuka wokulinganisa kanye nezinhlelo zokulawula kanye nolayini bokudlulisa idatha. Izinhlobo ezintsha zama-inverter zivame ukufakwa izixhumi ezivumela ukuqapha kwazo zonke izinhlelo. Imikhiqizo ifaka izinhlobo ezahlukahlukene zokuhlangana nezilinganiso ezahlukahlukene zamaza ahlukahlukene nenani elikhethiwe lamabhangqa. Njengesibonelo, singancoma uchungechunge lwe-DIN Rail olufakwe i-SPDs FLD2 uchungechunge noma umvikeli wokukhuphuka kwe-PoE ND CAT-6A / EA.

Cabanga ngezibonelo ezilandelayo zezicelo ezintathu eziyisisekelo: isiteshi samandla amancane se-PV ophahleni lwendlu yomndeni, isiteshi esiphakathi nendawo ophahleni lwesakhiwo sokuphatha noma sezimboni kanye nepaki enkulu elanga enwebeka ngaphezu kwesiqephu esikhulu.

Zonke izinhlobo zinikela ngokuvikelwa okusebenzayo kwemishini exhunywe kwimodi ejwayelekile nemiphumela yokwanda kwemodi ehlukile ngokuya nge-IEC 61643-21. Umkhawulo olinganisiwe wamanje wolayini abavikelwe ngamunye I_L <0,1A. Lawa madivayisi aqukethe amashubhu wokukhipha igesi, i-impedance yochungechunge, nokuhamba. Inani lamabhangqa avikelwe lingakhethwa (1-2). Lawa madivayisi akhiqizelwa amandla we-voltage phakathi kwebanga le-6V-170V. Isikhathi sokukhishwa esiphezulu ngu-10kA (8/20). Ukuvikelwa kolayini bezingcingo, kunconywa ukusebenzisa uhlobo olunamandla kagesi u-U_N= 170V.
