Sei Kudzivirirwa Kwekuvhiyiwa Kwakakosha MuSolar PV Systems?

Kana mainjiniya vachikurukura maitiro ekugadzira solar PV system Magadzirirwo emagetsi, kunyanya kutarisisa saizi yemagetsi ezuva ePV, kusarudzwa kwemagetsi emagetsi, uye magadzirirwo emabhatiri. Zvisinei, chimwe chinhu chakakosha chinokanganisa zvakananga kuvimbika kwemagetsi kudzivirira kukwira kwemagetsi.

Kuchinja-chinja kunokonzerwa nemheni uye mavoltage anochinja-chinja ndezvimwe zvezvikonzero zvinonyanya kukonzera kutadza kushanda kwe inverter, kukuvara kwe MPPT, uye kutadza kushanda zvakanaka kwe control system. Pasina dziviriro ye PV system yakagadzirwa zvakanaka, kunyangwe solar PV system yakagadzirwa zvakanaka inogona kusangana nenguva isingatarisirwi yekushanda uye kugadzirisa kunodhura.

Mumazuva ano dhizaini yesolar PV system, dziviriro yekukwira kwemagetsi haisi yekusarudza—inokosha pakuchengetedza magetsi uye kushanda kwenguva refu.

MaSolar PV SPDs Anodzivirira Sei Kubva Pakupfuura Mwero Kwemagetsi Kwenguva Pfupi?

A akasarudzwa nemazvo simba rezuva rePV SPD (mudziyo wekudzivirira kukwira kwesimba rezuva) unoderedza kukwira kwesimba kwesimba remagetsi kuburikidza nekutsausa simba remagetsi kuti riende pasi zvakachengeteka risati rasvika kuzvinhu zvinonzwa.

Manyuko eKupfuura Mwero muSolar PV Systems

1. Mheni inorova zvakananga kana kuti iri pedyo

2. Kukwira kwemagetsi kwakakonzerwa nekumhanya kwenguva refu kwetambo dzeDC

3. Kuchinja kwemasimba kubva mukukanganiswa kwegridi

4. Kuchinja kwemukati kwema inverters nemitoro mikuru

Zvese zviri zviviri sisitimu yezuva yePV yakasungirirwa pagrid uye sisitimu yezuva yePV yekunze kwegridi Magadzirirwo emagetsi ezuva eHybrid PV system anotarisana nekukwira kwakanyanya kuoma nekuda kwekubatana kwemabhatiri negrid.

Nzira yekudzivirira muDC neAC Circuits

Masisitimu ezuva ePV ane zvikamu zveDC neAC:

• Rutivi rweDC: Pakati pema solar panels ne inverter

• Rutivi rweAC: Pakati pe inverter nebhodhi rekuparadzira

Kudivi reDC, tambo dzine simba guru—kunyanya mumakambani makuru ekutengeserana—dzinoda dziviriro chaiyo yakaita seyakayerwa zvakanaka. mudziyo wekudzivirira kubuda kwezuva yakagadzirirwa ma PV input circuits. Mukushandiswa kwe high-voltage, DC SPDs dzinofanira kuenderana ne system voltage uye insulation class.

Giredhi rehunyanzvi Dziviriro yeDC pakuputika kwemhepo Mhinduro dzakagadzirirwa zvakananga nzvimbo dzine magetsi ezuva nezuva ane magetsi akawanda akazaruka uye mazinga emagetsi anochinja-chinja.

Kudivi reAC, dziviriro ye surge yakaiswa pa inverter output uye main distribution panel kudzivirira kubva pakukanganiswa kwegrid.

Midziyo Inodzivirira Kubuda Kwezuva Inofanira Kuiswa Kupi?

Nzvimbo chaiyo yekuisa chinhu chakakosha pakuisa marongerwo e solar PV system kuronga.

1. PaPV Array (DC Side Protection)

Kune masisitimu ane matambo marefu kana marongero edenga akafumurwa:

• Isa SPD pedyo nebhokisi rekubatanidza

• Kana kubatanidza SPD mukati mechikamu chekupinda che inverter DC

Izvi zvinodzivirira ma DC terminals e inverter kubva pakukwira kwemagetsi.

2. PaInverter AC Output

Mune sisitimu yezuva yePV yakasungirirwa pagrid, maSPD anowanzoiswa:

• Pa inverter AC output terminals

• Pabhodhi guru rekugovera reAC

Izvi zvinovimbisa kudzikiswa kwekuwedzera kwenzira yakazara.

3. PaBattery Storage Systems (Hybrid / Off-Grid)

Mukati sisitimu yezuva yehybrid PV uye sisitimu yezuva yePV yekunze kwegridi magadzirirwo:

• Isa maSPD pabhazi reDC rebhatiri

• Dzivirira MPPT charge controller input/output

• Iva nechokwadi chekubatana kwakakodzera kune system yekudzika

Masisitimu emabhatiri anowedzera kunzwa kwesisitimu nekuti magetsi emagetsi anoshanda nguva dzose ari pasi pemutoro.

Maitiro Ekubatanidza Dziviriro Yekukwira Mukugadzira Solar PV System?

Kana uri kuongorora maitiro ekugadzira solar PV system nemazvo, dziviriro yekukwira kwemvura inofanira kurongwa panguva yekutanga kwekugadzira—kwete kuwedzerwa gare gare.

Danho 1: Funga nezveDziviriro yeKuputika Munguva yeSaizi yeSolar PV System

Munguva saizi yesolar PV system, mainjiniya vanoverenga:

• Kuverenga saizi yemapaneru ezuva

• Saizi yemagetsi ezuva (solar inverter)

• Saizi yebhatiri rezuva

Panguva imwe chete, mwero wemagetsi esystem unofanirwa kutsanangurwa. Kusarudzwa kweSPD kunoenderana zvakananga ne:

• Maximum yakavhurika-circuit voltage (Voc)

• AC voltage yezita

• Rudzi rwehurongwa hwevhu

Kusateerera izvi padanho rehukuru kunowanzoita kuti SPD isaenzane.

Danho rechipiri: Kubatanidza maSPD muSolar PV Balance of System (BOS)

Midziyo yekudzivirira kukwira kweropa chikamu che BOS inoyera simba rezuva rePV rehurongwa hweBOS, zvinosanganisira:

• Mabhokisi ekubatanidza

• Kubviswa kweDC

• Maputsi eAC

• Mutongi wekuchaja weMPPT

• Masisitimu ekutarisa

MaSPD anofanirwa kurongeka nemabreaker uye kudimbura michina kuti ive nechokwadi chekuti anoshandiswa zvakanaka.

Mhinduro dzekudzivirira kupisa dzinovimbika dzePV system dzinofanira kuenderana nezvinodiwa zvekudzivirira kupisa kwe photovoltaic uye mamiriro ekunze anokanganisa nharaunda.

Unogona kutsvaga matekinoroji ekudzivirira e photovoltaic padanho remugadziri kuburikidza ne Leikexing kuti tinzwisise zviri nani nzira dzekubatanidza.

Kuti uwane gwara rekushandisa DC-side, mareferensi ehunyanzvi anowanikwa mune zvakatsaurirwa Dziviriro yeDC pakuputika kwemhepo zviwanikwa.

Danho rechitatu: Kugadzirisa Kugadzika uye Kugadzirisa Kurongeka kweCable

Kudzivirira kukwira kwemvura zvinobudirira kunoda:

• Kudzika kwepasi kwepasi-impedance

• Mafambiro mapfupi ekubatanidza SPD

• Kubatana kwakakodzera pakati pePV furemu uye system yekudzika

• Kudzivirira tambo dzemagetsi pakurongeka kwe solar PV system

Kugadzirwa kwechimiro chisina kunaka kunogona kuderedza kushanda kweSPD zvakanyanya, kunyangwe kana chiyero chemudziyo chakarurama.

Mhedziso

Kunzwisisa maitiro ekugadzira solar PV system zvivakwa zvinopfuura kusarudza module uye kugona kweinverter. Sisitimu yakasimba inofanira kunge iine dziviriro yakarongeka yePV system surge muDC neAC circuits.

Nekubatanidza michina yekudzivirira kubuda kwezuva muzvikamu zve solar PV system kubva pakutanga—panguva yekukura kwe solar PV system uye kuronga marongerwo ayo—mainjiniya anogona kuvandudza zvakanyanya kugadzikana kwesystem, kuchengetedzeka, uye kuvimbika kwekushanda kwayo kwenguva refu.

Kuti muwane mazano ehunyanzvi pakubatanidza dziviriro yekuputika kwemhepo mumagadzirirwo akaomarara e photovoltaic, rutsigiro rweinjiniya rwakananga runogona kukumbirwa kuburikidza nevakuru vehurumende. peji rekuonana.

Mibvunzo Inowanzo bvunzwa (Mibvunzo Inowanzo bvunzwa)

Sei kudzivirira kukwira kwemvura kuchikosha pakugadzira solar PV system?

Dziviriro yekukwira kwemagetsi inodzivirira overvoltage yenguva pfupi kubva kuma inverters anokuvadza, MPPT charge controllers, mabhatiri systems, uye electronics dzinoongorora, zvichiita kuti kushanda kugare kwenguva refu.

Ko sisitimu yega yega yezuva yePV inoda solar PV SPD here?

Ehe. Magadzirirwo ese ari maviri e solar PV system akabatana neasina grid anofanira kusanganisira maSPD akaongororwa zvakanaka pamativi eDC neAC kudzivirira mheni uye maswitching surges.

Ndingasarudza sei mudziyo wakakodzera wekudzivirira kukwira kwezuva?

Kusarudzwa kunoenderana nevoltage yesystem, rudzi rweinverter, grounding configuration, uye voltage yepamusoro-soro ye open-circuit inotsanangurwa panguva yekukura kwe solar PV system.

MaSPD anofanira kuiswa kupi mu hybrid solar PV system?

Mumasystem ehybrid, maSPD anofanirwa kuiswa padivi rePV array DC, inverter AC output, uye DC storage bus yebhatiri kuti ive nechokwadi chekudzivirira nzira yese.

Ko kudzivirira mafungu emvura chikamu cheSOlar PV balance of system (BOS) here?

Ehe. Midziyo yekudzivirira kukwira kwemvura inorongwa sechikamu che solar PV balance ye system BOS, pamwe chete ne disconnects, cables, uye combiner equipment.
