Hopolokelo ea matlaindasteri, PCS, kapa Power Conversion System, sesebelisoa sa polokelo ea matla.
Hangata polokelo ea betri e arotsoe ka maemo a mararo a maholo a kopo: polokelo e kholo, polokelo ea khoebo le ea indasteri, le polokelo ea malapa, le li-PCS / inverters tse lumellanang le maemo a fapaneng le tsona li fapane haholo. Sehlooho sena se khetholla PCS bakeng sa polokelo e kholo, PCS bakeng sa polokelo ea indasteri le ea khoebo, le PCS bakeng sa polokelo ea malapa ho tloha likarolong tse 'nè tse pharaletseng: tekanyo ea matla, maemo a kopo, litlhoko tsa theknoloji, litšenyehelo le theko, ka ho latellana.
I. Sekala sa Matla
Likhomphutha tse kholo tsa polokelo:
Boemo ba matla bo phahame, hangata boemong ba MW (megawatt), bo ka ba holimo ho 100MW kapa ho feta. Litsamaiso tse kholo tsa polokelo ea matla li ka boloka ho fihla ho lihora tse 'maloa tsa megawatt kapa esita le lihora tse makholo tsa matla a megawatt ho tsamaisana le litlhoko tse kholo tsa polokelo ea matla a marang-rang, ho fihlela taolo ea maqhubu a marang-rang, phetoho ea tlhoro le mesebetsi e meng.
Li-PC tsa polokelo ea khoebo le ea indasteri:
Matla ka kakaretso a pakeng tsa mashome a kW (kilowatts) le MW tse 'maloa. E sebetsa ho basebelisi ba indasteri le ba khoebo, matla a polokelo a tloha ho makholo a 'maloa a kWh ho ea ho likete tse' maloa tsa kWh, e sebelisetsoang ho sebetsana ka katleho le litefiso tse phahameng le ho finyella litlhoko tsa ho tšepahala ha matla.
Li-PC tsa polokelo ea malapa:
Matla a manyane, hangata a pakeng tsa kW tse seng kae le tse leshome le metso e 'meli tsa kW. Haholo-holo e sebeletsa polokelo ea motlakase ea PV lapeng le matla a tšohanyetso,tsamaiso ea ntlo ea polokelo ea matlamatla ka kakaretso a maemong a kWh tse seng kae ho isa ho mashome a kWh.
II. Maemo a Kopo
Likhomphutha tse kholo tsa polokelo:
Grid-side: ho leka-lekanya phepelo le tlhokeho ea marang-rang, ho bebofatsa tlhahiso ea nakoana ea matla a moea le tlhahiso ea matla a photovoltaic, le ho ntlafatsa boleng le botsitso ba matla a marang-rang. Ka mohlala, ha mochine o moholo oa motlakase oa photovoltaic o hokahane le marang-rang, o ka boloka matla a feteletseng motšehare le ho lokolla matla bosiu kapa ka matsatsi a maru.
Ho ts'ehetsa liteishene tse kholo tsa motlakase: sebelisana le liteishene tse kholo tsa motlakase kapa tse fehlang motlakase ka metsi ho etsa taolo e kopaneng ea maqhubu, ho arabela ka potlako tlhokong ea taolo ea maqhubu a grid, le ho ntlafatsa ts'ebetso ea taolo ea maqhubu a sistimi ea motlakase.
Li-PC tsa polokelo ea khoebo le ea indasteri:
Ho kuta litlhoro le ho tlatsa liphula: basebelisi ba liindasteri le khoebo ba boloka motlakase nakong ea theko ea motlakase ebe ba o lokolla nakong ea tlhoro ho fokotsa litšenyehelo tsa tšebeliso ea motlakase. Ka mohlala, litsi tsa data li lefella bosiu 'me li tsoa motšehare ho fokotsa tlhokahalo ea tlhōrō ea matla a marang-rang.
Tiisetso ea phepelo ea matla a tšohanyetso: Fana ka tšehetso ea matla a tšohanyetso bakeng sa lisebelisoa tsa bohlokoa tsa likhoebo ha marang-rang a motlakase a hloleha, 'me u netefatse ts'ebetso ea mantlha ea likhoebo le ts'ebetso e tloaelehileng ea lits'ebeletso tsa bohlokoa.
Li-PC tsa polokelo ea malapa:
Ts'ehetso ea ho fehla motlakase oa lelapa: e sebetsa ka mokhoa o ts'oanang le sistimi ea letsatsi ea photovoltaic ea lelapa ho fetolela matla a DC ho motlakase oa AC bakeng sa ts'ebeliso ea lelapa, ka matla a feteletseng a bolokiloeng ka har'a betri ho ntlafatsa ho iphelisa ka matla ka lapeng.
Emergency Backup Power: E fana ka ts'ireletso ea mantlha ea matla bakeng sa malapa nakong ea ho tima grid, ho boloka ts'ebetso ea lisebelisoa tsa bohlokoa tse kang mabone, lihatsetsi le lisebelisoa tsa puisano.
Ⅲ. Litlhoko tsa Tekheniki
Likhomphutha tse kholo tsa polokelo:
Phetoho e sebetsang hantle: ho sebetsa hantle haholo hoa hlokahala, ka kakaretso ka holimo ho 95%, ho fokotsa tahlehelo ea matla le ho ntlafatsa moruo oa tsamaiso ea polokelo ea matla.
Lebelo la karabo: E ka arabela ka potlako ho litaelo tsa ho romela marang-rang, ea fetola matla a ho tjhaja le ho ntša matla ka li-milliseconds ho boloka botsitso ba grid.
Khokahano ea Sistimi: Khokahano e ntle le lits'ebetso tsa betri tse kholo tsa polokelo ea matla le sistimi e rarahaneng ea grid, e ikamahanyang le litšobotsi tse fapaneng tsa betri le litlhoko tsa phihlello ea grid.
Li-PC tsa polokelo ea indasteri le ea khoebo:
Ho tšepahala: ho tšepahala ho phahameng, ho fokotsa nako ea phoso, ho kopanaindasteri le khoebotlhahiso e tsoelang pele kapa litlhoko tsa ts'ebetso, li hloka nako e telele e tloaelehileng e se nang liphoso.
Power Factor Regulation: E laola matla a motlakase ka katleho, e ntlafatsa boleng ba motlakase bakeng sa basebelisi ba indasteri le khoebo, 'me e fokotsa litšenyehelo tsa motlakase tsa khoebo ka matšeliso a sebetsang.
Li-PC tsa polokelo ea malapa:
Tšireletseho: e nang le sistimi e phethahetseng ea taolo ea betri ho thibela ho tjhaja ho feta tekano, ho chacha ho feta tekano le ho potoloha ho khuts'oane ha libeteri ho netefatsa polokeho ea botho le thepa ea basebelisi ba malapa.
Tšebeliso e bonolo: e bonolo ho sebetsa le ho e boloka, e nang le sebopeho se bonolo le se bonolo ho utloisisa, ho bonolo ho kenya le ho kopanya tsamaisong ea matla a ntlo.
Ⅳ. Litšenyehelo le Litheko
Likhomphutha tse kholo tsa polokelo:
Litšenyehelo li holimo, 'me litheko li ka ba lidolara tse likete ka kilowatt. Matla a phahameng, litlhoko tsa tekheniki tse rarahaneng haholo, le tlhahiso ea tlhahiso e ngata li fella ka R&D e phahameng, thepa e tala le litšenyehelo tsa tlhahiso, empa litheko li fokotseha butle-butle ka litlamorao tse kholo le tsoelopele ea mahlale.
Li-PC tsa polokelo ea khoebo le ea indasteri:
Litsenyehelo le theko li pakeng tsa li-PC tse kholo tsa polokelo le li-PC tsa polokelo ea malapa, 'me theko ka kW e ka ba ho pota 1000 - 5000 Dollars. Theko e angoa ke matla, ts'ebetso, mofuta le lintlha tse ling, ho khutlisa matsete ke ntlha ea bohlokoa bakeng sa basebelisi ba indasteri le ba khoebo ho nahana ka ho reka.
Li-PC tsa polokelo ea malapa:
Litsenyehelo li batla li le tlaase, 'me theko ka kW e ka tloha ho lidolara tse makholo a seng makae ho ea ho liranta tse ka bang 2,000. Matla a manyenyane, mosebetsi o batla o le bonolo, ka ho atolosoa ha 'maraka oa polokelo ea matla a ntlo, theko e lebeletsoe hore e fokotsehe ka ho eketsehileng ho ntlafatsa kamohelo ea basebelisi ba malapa.
Li-PCS tse kholo tsa polokelo bakeng sa lits'ebetso tse kholo tsa marang-rang le lits'ebetso tsa seteishene sa matla, matla a phahameng, litlhoko tse thata tsa tekheniki, litšenyehelo tse phahameng; liindasteri le tsa khoebo polokelo PCS ditshebeletso indasteri le khoebo tlhoro ho kuta le maemo a tšohanyetso, matla a itekanetseng, ho tšepahala ho boima, joalo-joalo, theko e mahareng; polokelo ea malapa PCS bakeng sa PV ea lapeng le ts'ebeliso ea tšohanyetso, matla a manyane, polokeho ea lintlha le boiketlo ba tšebeliso, litšenyehelo tse tlase.
