Ib tug phooj ywg xav kom kuv qhia txog cov ntsiab lus tseem ceeb ntawm photovoltaic fais fab nroj tsuag. Nws tuaj yeem pom tias cov peev txheej zoo li no tsis yooj yim nrhiav hauv online. Qhov tseeb, nws tsis xav tias photovoltaics yog kev lag luam tawm zog. Txawm hais tias ntau lub tsev kawm qib siab thiab cov tsev kawm qib siab muaj cov kev kawm tshwj xeeb uas muaj feem xyuam nrog photovoltaic, lawv txhua tus zoo li cov menyuam mos thiab tsis muaj ntau yam kev pab.
Kuv muaj qee lub sijhawm dawb, thiab kuv yuav ua neej nyob raws li kuv tus phooj ywg kev ntseeg siab, yog li kuv yuav qhia qee yam txog cov chaw nres tsheb photovoltaic. Kuv lub peev xwm muaj tsawg, yog li thov sau ntawv los kho kuv yog tias kuv ua yuam kev.
Qhov ntsuas ntawm photovoltaic fais fab chaw nres tsheb tuaj yeem faib ua peb pawg, xws li chaw nres tsheb me, nruab nrab thiab chaw nres tsheb loj. Cov chaw nres tsheb me me muaj peev xwm nruab tau tsawg dua 1 MW, qhov nruab nrab cov chaw nres tsheb muaj peev xwm nruab ntawm 1-30 MW, thiab cov uas muaj peev xwm nruab ntau dua 30 MW yog tag nrho cov chaw nres tsheb loj.
Tam sim no, Shanxi Datong National Advanced Technology Photovoltaic Demonstration Base muaj tag nrho cov peev txheej ntawm 3,000MW; Shanxi Yangquan National Advanced Technology Photovoltaic Power Generation Base muaj tag nrho cov peev txheej ntawm 2,200MW; Shandong Xintai Photovoltaic Power Generation Demonstration Base muaj tag nrho cov peev txheej ntawm 2, 000MW, nrog rau qhov nruab nrab txhua xyoo tsim hluav taws xob txog li 2,894.19 lab degrees, uas tuaj yeem txuag tau 1.01 lab tons ntawm cov qauv thee.
1 MW =1000KW. Lub chaw tsim hluav taws xob photovoltaic nrog lub peev xwm ntawm 1MW yog txaus los txhawb lub zog xav tau ntawm lub lag luam me.
Nyob ntawm qhov chaw teeb tsa, nws tuaj yeem muab faib ua cov chaw nres tsheb photovoltaic hauv nruab nrab thiab faib cov chaw nres tsheb photovoltaic. Centralized fais fab chaw nres tsheb yog qhov nruab nrab thiab loj fais fab chaw nres tsheb, thaum lub zog hauv zos yog cov chaw me me.
Centralized power stations mas concentrated nyob rau hauv cov cheeb tsam uas lub teeb lub zog yog concentrated. Lawv tuaj yeem siv tag nrho cov khoom siv hluav taws xob hauv cheeb tsam, txuas rau daim phiaj hluav taws xob, thiab xa tawm hluav taws xob hluav taws xob. Kev faib hluav taws xob feem ntau yog siv rau tus kheej. Yog tias lub zog siv tsis tau, nws tuaj yeem txuas nrog lub network rau kev sib kis sab nraud.
Qhov chaw nres tsheb photovoltaic thaum kawg yuav txuas nrog lub network. Nws raug faib raws li qib voltage ntawm lub network. Lub chaw nres tsheb photovoltaic tuaj yeem txuas nrog 400V system lossis 10-35Kv system. Nws tseem tuaj yeem txuas nrog 66Kv thiab siab dua qhov system raws li xav tau. Qhov no yuav tsum tau ua tiav los ntawm ib tug booster transformer. Cov kev cai nkag mus rau Network.
Tag nrho cov chaw nres tsheb photovoltaic tuaj yeem suav tau tias yog ib qho kev ywj pheej, uas feem ntau muaj lub hnub ci ntawm tes, lub thawv sib txuas, DC faib txee, inverter, AC faib txee, hnub ci kev tswj xyuas qhov system, thiab kab sib chaws nkag ( boost, ntsuas thiab lwm yam khoom siv), kev saib xyuas thiab kev sib txuas lus, kev tiv thaiv hluav taws xob hauv av thiab lwm yam khoom siv.
Hnub ci photovoltaic modules hloov lub hnub ci ncaj qha mus rau qhov tam sim no. Lub photovoltaic modules txuas nrog rau tib lub sijhawm rau DC faib txee los ntawm DC lub thawv sib txuas. Tom qab converging, lawv txuas nrog DC input kawg ntawm lub inverter los hloov lub zog DC rau hauv alternating tam sim no. AC tso zis kawg ntawm lub inverter yog txuas nrog lub AC faib txee yog ncaj qha mus rau cov neeg siv sab los ntawm lub AC faib txee los yog txuas nrog rau lub hwj chim daim phiaj tom qab hloov los ntawm ib tugkauj ruam-up transformer. Qhov no yog lub hauv paus ntsiab lus ua haujlwm ntawm tag nrho photovoltaic system.
Kab lus no yuav xub tham txog kev faib tawm thiab cov txheej txheem ntawm cov chaw nres tsheb photovoltaic, nrog rau cov hauv paus ntsiab lus ua haujlwm ntawm tag nrho cov kab ke. Yog tias muaj dab tsi tsis tsim nyog, thov sau ntawv los kho nws.
