Qhov cuam tshuam ntawm daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob rau yav tom ntej fais fab kev loj hlob

Qhov cuam tshuam ntawm daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob rau kev tsim kho kab sib chaws yav tom ntej:
1. Kev cuam tshuam ntawm load ncov thiab hav ntawm daim phiaj fais fab. Vim hais tias daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob tsis muaj peev xwm ntawm kev tswj hwm lub ncov thiab kev tswj hwm zaus, nws yuav muaj kev cuam tshuam rau thaum sawv ntxov ncov load thiab yav tsaus ntuj peak load ntawm daim phiaj. Qhov nce hauv lub zog tsim hluav taws xob ntawm daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob tsis txo cov naj npawb ntawm cov khoom siv rotary. Daim phiaj hluav taws xob yuav tsum tau npaj ntau qhov kev sib hloov ntawm cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob photovoltaic los daws cov teeb meem ntawm qhov chaw thau khoom thaum sawv ntxov thiab yav tsaus ntuj. Daim phiaj-txuas hnub ci photovoltaic fais fab tsim tshuab muab lub zog rau hauv daim phiaj ntawm tus nqi txo cov sij hawm ntawm ib chav tsev ntawm kev siv, uas tau kawg tsis yog qhov tsim hluav taws xob xav pom.
2. Kev hloov pauv nruab hnub thiab hmo ntuj, qhov sib txawv ntawm lub sijhawm sab hnub tuaj-sab hnub poob thiab lub caij nyoog hloov ntawm daim phiaj hluav taws xob. Vim lub sij hawm ntawm lub hnub ci thiab kev thauj khoom, qhov nce hauv lub zog tsim hluav taws xob ntawm daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob tsis tuaj yeem txo qhov kev thov rau lub peev xwm ntawm daim phiaj.
3. Cov kev hloov hauv huab cua. Thaum lub nroog photovoltaic ru tsev daim phiaj-kev sib txuas hluav taws xob mus txog ib qho kev ntsuas, yog tias thaj chaw thiab huab cua hloov pauv zoo heev, daim phiaj yuav muab cov chav nyob hauv cheeb tsam rotating txaus thiab muaj peev xwm them rov qab rau cov phiaj xwm txuas nrog hnub ci photovoltaic lub zog tsim los tswj thiab kho qhov zaus thiab voltage ntawm qhov system. Hauv qhov no, daim phiaj hluav taws xob yuav txi cov kev lag luam kev lag luam kom ntseeg tau tias kev ua haujlwm ruaj ntseg thiab ruaj khov ntawm daim phiaj hluav taws xob.
4. Ntev-ntev photovoltaic fais fab kis. Thaum daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob yog kev lag luam thiab kev muaj peev xwm ntawm kev sib kis mus ntev, nws yuav ua rau muaj teeb meem kev ruaj ntseg tshiab rau AC daim phiaj vim tias tsis muaj kev sib hloov inertia, tus tswv xeev thiab excitation system rau daim phiaj-txuas photovoltaic fais fab tiam. Yog tias daim phiaj sib txuas nrog photovoltaic fais fab tsim tsim cov nplai siv hluav taws xob siab AC / DC kis tau tus mob, nws yuav ua rau muaj kev ruaj ntseg thiab teeb meem nyiaj txiag rau AC system uas nyob ib sab ntawm daim phiaj txuas nrog photovoltaic fais fab kis. Cov kab sib kis tau mob siab rau daim phiaj-kev sib txuas ntawm photovoltaic lub zog tsim hluav taws xob, vim qhov ua haujlwm qis, yuav txwv kev siv suab puam hnub ci zog. Cov kab sib kis tau siv los qiv los yog coj mus rau hauv tus account cov hluav taws xob ntawm daim phiaj-txuas hnub ci photovoltaic fais fab kev tsim hluav taws xob, vim qhov qis qis, tsis muaj nyiaj txiag. Txawm hais tias siv high voltage AC los yog DC kis tau tus mob, photovoltaic daim phiaj-txuas fais fab chaw nres tsheb yuav tsum tau nruab nrog tsis siv neeg reactive voltage tswj li. Raws li qhov cuam tshuam rau kev ruaj ntseg ntawm daim phiaj hluav taws xob, tsis muaj cov qauv lej ntawm kev tsim hluav taws xob photovoltaic (nrog rau cov qauv siv hluav taws xob thiab cov qauv thauj khoom) hauv kev ntsuas hluav taws xob ruaj khov. Nws tseem tsis tau paub meej tias yuav muaj kev cuam tshuam ntau npaum li cas photovoltaic fais fab kev lag luam ntawm daim phiaj.
5. Cov teeb meem kev noj haus. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm daim phiaj txuas nrog photovoltaic fais fab tuag yog tias nws tuaj yeem hloov pauv kev noj cov fossil fuels. Vim hais tias daim phiaj-txuas photovoltaic zog tsim ua kom lub teb chaws cia lossis thermal cia ntawm lub tshuab fais fab rotating generator, qhov kev txo qis ntawm daim phiaj-txuas photovoltaic lub zog tsim hluav taws xob yuav tsum txiav tawm lub zog poob los ntawm rotary reserve lossis thermal reserve. Kev txo qis kev ua haujlwm ntawm daim phiaj-txuas photovoltaic lub zog tsim hluav taws xob yuav tsum xav txog qhov kev ua haujlwm poob los ntawm kev txo qis hauv cov sij hawm siv ntawm lub tshuab hluav taws xob ntawm lub tuam txhab tsim hluav taws xob vim hluav taws xob muab los ntawm daim phiaj-txuas hnub ci photovoltaic lub zog tsim hluav taws xob. Vim tias lub zog hluav taws xob ua haujlwm tag nrho, photovoltaic daim phiaj sib txuas hluav taws xob tsim hluav taws xob rau hauv daim phiaj yuav cuam tshuam rau kev nyiam ntawm lwm lub tshuab hluav taws xob, uas yog ib qho teeb meem uas cov neeg tsim cai yuav tsum xav txog. Qhov no yog vim qhov kev xav tias nyob rau hauv thiaj li yuav kom cov kab sib chaws ua haujlwm zoo, ruaj khov thiab kev lag luam, nws tsis yog tsuas yog yuav tsum tau siv lub tshuab hluav taws xob ua hluav taws xob los ua kev hloov pauv. Yog li ntawd, theoretical standard thee consumer txo qhov sib npaug rau tag nrho cov nyiaj ntawm photovoltaic daim phiaj-txuas txuas fais fab hauv lub kaw lus yuav tsum tau muab faib los ntawm qhov zoo tshaj 1, thiab cov nroj tsuag hluav taws xob poob ntawm lub rotating standby unit yuav tsum tau muab rho tawm hauv qhov sib npaug.
Cov mis rau kev txiav txim qhov kev txo qis ntawm kev siv hluav taws xob photovoltaic:
w =[(Wc/Wn)* Wp-(Pc/Pn)Pd);1
1) W -- kev txo qis ntawm daim phiaj-txuas photovoltaic fais fab tuag (tus qauv rau thee);
2) Wc - tag nrho thermal zog tsim ntawm daim phiaj fais fab;
3) Wn -- tag nrho lub zog tsim ntawm daim phiaj;
4) Wp -- Theoretical noj txo ntawm daim phiaj-connected photovoltaic fais fab tuag (tus qauv rau thee)
5) PC-tag nrho lub zog noj ntawm thermal fais fab nroj tsuag (tus qauv thee);
6) Pn- tag nrho cov nroj tsuag siv hluav taws xob hauv daim phiaj hluav taws xob (tus qauv thee);
7) Lub zog poob ntawm PD-rotary standby chav tsev (tus qauv thee).
6. Kev tiv thaiv ib puag ncig; Txawm hais tias qhov kev txo qis ntawm cov hluav taws xob hluav taws xob photovoltaic yuav tsum tsuas yog xav txog cov sulfur dioxide thiab carbon dioxide emissions ntawm thermal zog tiam tseem yuav tau kawm, vim hais tias thaum photovoltaic fais fab tuag txuas nrog daim phiaj, daim phiaj tseem xav txog kev nyab xeeb, kev ruaj ntseg thiab kev lag luam. kev khiav hauj lwm ntawm daim phiaj, feem ntau tsis yog tsuas yog thermal fais fab nroj tsuag txo cov zis, tab sis kuj txiav txim siab qhov kev sib hloov ntawm standby. Tsis yog nws tsuas yog cov chaw tsim hluav taws xob hydropower uas ua haujlwm ntawm kev hloov pauv rov qab (cov nroj tsuag dej muaj tsawg dua los ntawm kev hloov cov haujlwm thaub qab).
