Na liphanele tsa letsatsi li ka hlahisa motlakase o hokahaneng ka kotloloho le mochini o kenang motlakaseng?

Matla a hlahisoang keliphanele tsa letsatsi e ka kopanngoa ka ho toba le inverter, e leng e 'ngoe ea mekhoa e tloaelehileng ea ho hlophisa lisebelisoa tsa letsatsi la photovoltaic. Phanele ea letsatsi, eo hape e tsejoang e le photovoltaic (PV) panel, ke sesebelisoa se fetolang khanya ea letsatsi hore e be motlakase o tobileng oa hona joale. Leha ho le joalo, lisebelisoa tse ngata tsa motlakase, ho kenyeletsoa lisebelisoa tsa lapeng le li-motor tsa indasteri, hangata li sebelisa alternating current (AC). Ka hona, e le hore matla a hlahisoang ke lisebelisoa tsa letsatsi a sebelisoe ke lisebelisoa tsena, matla a DC a hloka ho fetoloa matla a AC ka inverter.

Mokhoa oa ho hokahanya liphanele tsa letsatsi homochini o kenya letsoho

Liphanele tsa letsatsi hangata li hokahantsoe le inverter ka letoto kapa ka ho bapisa. Khokahanong ea letoto, liphanele tsa letsatsi li hokahane hammoho ho hlahisa boemo ba motlakase bo hlokahalang, ha li ntse li hokahantsoe ka mokhoa o ts'oanang, liphanele tsa letsatsi li hokahane hammoho ho fana ka boemo bo hlokahalang hajoale. Li-inverters li ka ba bohareng, likhoele kapa li-micro-inverters ho latela litlhoko tsa sistimi le moralo.

1. Inverter e bohareng: E ​​sebelisoa lits'ebetsong tse kholo tsa photovoltaic, lisebelisoa tse ngata tsa letsatsi li hokahane ka letoto 'me li tsamaellana le ho kenya letsoho ha DC ea inverter e le' ngoe.
2. Inverter ea likhoele: Khoele e 'ngoe le e' ngoe ea solar panel e feta ka inverter, e ntlafatsang ts'ebetso ea khoele ea photovoltaic mme e ntlafatsa ts'ebetso ea sistimi le ts'epahalo.

3. Microinverter: Phanele e 'ngoe le e' ngoe ea letsatsi kapa liphanele tse 'maloa li hokahane le microinverter e arohaneng, e ka fihlelang ho latela lintlha tse phahameng tsa matla (MPPT) bakeng sa phanele ka' ngoe le ho ntlafatsa ts'ebetso ea kakaretso ea sistimi.

Tsela eo inverter e sebetsang ka eona

Mosebetsi oa mantlha oa inverter ke ho fetolela matla a DC hore e be matla a AC. Ts'ebetso ena e kenyelletsa ho sebelisa lisebelisoa tsa elektroniki tsa motlakase, joalo ka li-transistors le diode, ho kopanya maqhubu a feto-fetohang ka ho feto-fetoha ha molumo oa pulse (PWM) kapa mekhoa e meng ea ho feto-fetoha ha molumo. Inverter e ka 'na ea boela ea e-ba le algorithm e phahameng ea ho latela lintlha tsa matla (MPPT) ho etsa bonnete ba hore lisebelisoa tsa letsatsi li lula li sebetsa sebakeng sa tsona se phahameng sa matla.

Inverter e sebetsang hantle le ts'ebetso

Ho sebetsa hantle ha inverter ke tekanyo ea bohlokoa ea ts'ebetso ea eona. Li-inverters tse sebetsang hantle haholo li ka fokotsa tahlehelo nakong ea phetolo ea matla le ho eketsa tlhahiso ea motlakase ka kakaretso ea sistimi. Ho sebetsa hantle ha inverter ho angoa ke lintlha tse ngata, ho kenyelletsa moralo oa eona, lisebelisoa tsa elektronike tse sebelisoang, tsamaiso ea mocheso le li-algorithms tsa taolo.

Mehopolo ea Moralo oa Sisteme

Ha ho etsoa moralo oa tsamaiso ea letsatsi la photovoltaic, lintlha tse latelang li lokela ho nkoa:

1. Kakaretso ea matla a solar panel: Sena se lekanyetsa boholo ba motlakase oo tsamaiso e ka o hlahisang.

2. Bokhoni ba inverter: Inverter e lokela ho khona ho sebetsana le matla a mangata a hlahisoang ke liphanele tsa letsatsi.

3. Tšireletso ea Sisteme: Inverter e lokela ho ba le mesebetsi e mengata ea ts'ireletso, potoloho e khuts'oane le ts'ireletso e feteletseng.

4. Tšebelisano: Inverter e lokela ho lumellana le liphanele tsa letsatsi le sistimi ea grid.

5. Tlhophiso le Tlhokomelo: Inverter e lokela ho kengoa ho latela litataiso tsa moetsi le ho hlokomeloa khafetsa ho netefatsa ts'ebetso e nepahetseng ea sistimi.

Tšireletso le ho latela melao

Sistimi ea Solar PV le li-inverters li tlameha ho raloa le ho kengoa ho latela likhoutu tsa motlakase tsa lehae le litekanyetso tsa polokeho. Li-inverters hangata li hlokoa ho ba le litifikeiti tse hlokahalang tsa polokeho, joalo ka IEC 62109-1 le IEC 62109-2.

Lekola le ho hlokomela

Li-inverters tsa sejoale-joale li na le lisebelisoa tsa ho beha leihlo tse ka lekola ts'ebetso ea sistimi ka nako ea nnete, ho kenyelletsa tlhahiso ea matla, boemo ba inverter le lialamo tsa phoso. Sena se thusa basebelisi ba sistimi ho ntlafatsa ts'ebetso ea sistimi le ho arabela kapele litabeng life kapa life.

ha re phethela

Sistimi ea ho fehla matla a solar panel e sebelisa inverter ho fetolela motlakase o otlolohileng hore e be oa hona joale o sebelisoang ho grid ea motlakase kapa ka kotloloho bakeng sa ts'ebeliso ea lapeng. Ho khetha inverter e nepahetseng ho bohlokoa ho netefatsa ts'ebetso e nepahetseng ea sistimi le ho eketsa phaello ho matsete. Moralo oa sistimi o lokela ho ela hloko mofuta, katleho, polokeho le litlhoko tsa tlhokomelo ea inverter, ha o ntse o latela melao le litekanyetso tse amehang.
