Kutchuka kwa msika wa solar photovoltaic kwayendetsa chitukuko cha solarinvertermakampani.Nthawi zambiri, ma inverters a solar amagawidwa m'mitundu itatu: ma inverters apakati, ma inverters a zingwe, ndi ma inverters ang'onoang'ono.
Ma inverters apakati, omwe amalumikizana koyamba kenako ndikusintha, amakhala oyenera kwambiri pamagetsi akuluakulu apakati okhala ndi zowunikira zofanana.Chifukwa cha mtengo wake wotsika, amagwiritsidwa ntchito makamaka m'malo akuluakulu apakati pamagetsi a photovoltaic monga mafakitale akuluakulu okhala ndi dzuwa lofanana ndi malo opangira magetsi m'chipululu.
Ma inverters a zingwe amagwiritsidwa ntchito kutembenuza kenako kutembenuza, makamaka pamadenga ang'onoang'ono ndi apakatikati, zida zazing'ono zamagetsi zapansi, ndi zina.Zochitika zogwiritsira ntchito ndizosiyana kwambiri, ndipo zingagwiritsidwe ntchito ku mitundu yosiyanasiyana ya magetsi, monga malo opangira magetsi apakati, malo opangira magetsi ogawidwa, ndi malo opangira magetsi padenga, ndi mtengo wokwera pang'ono kuposa malo opangira magetsi apakati.
Ma Micro inverters amatembenuzidwa mwachindunji ndikulumikizidwa ku gridi, makamaka oyenera zochitika zapakhomo ndi zazing'ono zogawira.Nthawi zambiri, mphamvuyo imakhala pansi pa 1kw, makamaka yomwe imagwira ntchito panyumba zogawika komanso zazing'ono zogawira magetsi padenga ndi malonda, koma mtengo wake ndi wokwera, ndipo ndizovuta kusunga ngati zalephera.
Utsogoleri wotsika mtengo
The inverter industryisanafike 2010 sichinali cha China.Monga msika wofunikira kwambiri wa photovoltaic, Europe idawerengera zoposa 60% ya mphamvu yatsopano yapadziko lonse lapansi yapadziko lonse lapansi pakati pa 2004 ndi 2011. Monga mphamvu yayikulu yamagetsi, SMA, chimphona cha photovoltaic, idayamba kupanga ma inverters a photovoltaic mu 1987, ndikuyambitsa woyamba malonda mndandanda inverter ndi centralized inverter, kutsogolera makampani podalira ubwino luso.
Msika wapadziko lonse lapansi watsala pang'ono kulamulidwa ndi makampani aku Europe, ndipo pakati pa 10 zapamwamba zotumizira ma photovoltaic inverter, kupatula makampani atatu aku North America, ena onse aku Europe.Makampani asanu aku Europe, SMA, KACO, Fronius, Ingeteam, ndi Nokia okha, amawerengera 70% ya msika.Gawo la msika la makampani a SMA lafika 44%, lofanana ndi theka la msika wa photovoltaic inverter.
Pa nthawi yomwe chitukuko cha photovoltaic chikuyenda bwino ku Ulaya, chitukuko cha photovoltaic cha China chikadali chaching'ono: kusowa kwa kafukufuku wamakono ndi chitukuko cha chitukuko chakhala chinthu chachikulu cholepheretsa chitukuko.Monga tonse tikudziwira, ma inverters a photovoltaic amagwirizanitsa gulu la photovoltaic ndi gridi yamagetsi, yomwe imatha kusintha mphamvu ya DC yopangidwa ndi dongosolo kukhala mphamvu ya AC yofunikira pa moyo kudzera mu teknoloji yotembenuza magetsi, ndipo imatha kutchedwa mtima wa dongosolo lonse la photovoltaic.
Monga "ubongo" wamagetsi opangira magetsi a photovoltaic, kupanga ndi kupanga kwake kumagwirizanitsa luso la mapangidwe a mphamvu, teknoloji ya semiconductor, teknoloji yamagetsi yamagetsi, teknoloji ya microcomputer, teknoloji ya mapulogalamu a algorithm, ndi zina zotero. mgwirizano kuti amalize, ma inverters ali ngati atsogoleri omwe akugwiritsa ntchito zigawo zina ndi ubongo wawo, ndipo kusuntha kwawo kulikonse kudzakhudza mwachindunji machitidwe onse a photovoltaic.
Kutembenuka kwake bwino ndi kudalirika kwakhalanso zizindikiro zazikulu zoweruza ntchito ya inverter.Malingana ngati mphamvuyo imakhala yochuluka, imatha kutanthauza kutayika kochepa, komwe ndi chimodzi mwazofunikira kwambiri pakuchepetsa mtengo wamagetsi pa ola la kilowatt pamapulojekiti a photovoltaic.Mu Disembala 2003, Sungrow Power idakhazikitsa gridi yoyamba yaku China ya 10kW photovoltaic yolumikizidwa inverter yokhala ndi ufulu wodziyimira pawokha waluso, zomwe zidapita patsogolo kwambiri pakutembenuka mtima ndikuphwanya maulamuliro akunja.
Kuphatikiza kosungirako kwa Optical ndi njira yosapeŵeka
Magetsi opangidwa ndi grid-olumikizidwa ndi photovoltaic inverter amatha kutembenuza njira imodzi yokha kuchokera ku DC kupita ku mphamvu ya AC, ndipo amangopanga magetsi masana.Mphamvu zomwe zimapangidwa zimatha kukhudzidwanso ndi nyengo, yomwe ili ndi zovuta zosayembekezereka.Komabe, inverter yosungiramo mphamvu imagwirizanitsa ntchito za magetsi opangidwa ndi magetsi opangidwa ndi magetsi a photovoltaic gridi ndi magetsi osungiramo mphamvu, kusunga mphamvu yamagetsi ikakhala yochuluka, ndikutembenuza mphamvu yamagetsi yosungidwa pamene sikukwanira kuitulutsa ku gridi, kugwirizanitsa mphamvu. kusiyana pakati pa usana ndi usiku ndi nyengo zosiyanasiyana, kumathandizira pakumeta kwambiri komanso kudzaza zigwa.
Inverter yosungirako mphamvu ndi grid yolumikizidwa inverter ili ndi ukadaulo womwewo.Ngakhale dera lodzitchinjiriza ndi dera lozungulira ndi losiyana, nsanja ya hardware ndi mawonekedwe a topology ndizofanana, chifukwa chake njira yochepetsera mtengo imagwirizana kwambiri ndi photovoltaic.inverter.
M'kanthawi kochepa, kufunikira kosungirako mphamvu ndi kukhazikitsa kumayendetsedwa makamaka ndi mbali ya ndondomeko, ndikukhudzidwa ndi zopinga pa malo otsekemera ndi kusinthasintha kwa magetsi, maboma osiyanasiyana adafulumizitsa kukhazikitsidwa kwa ndondomeko zoyenera zolimbikitsa msika wogulitsa mphamvu. .Machigawo ndi mizinda ina ku China adalamulanso kugawa ndi kusunga mphamvu zatsopano.
Pakapita nthawi, kuphatikiza kwa kuwala ndi kusungirako ndi njira yosapeŵeka, ndipo ndondomeko ziyenera kulimbikitsa kugawa ndi kusunga mphamvu zatsopano.Mwachidziwitso, panthawi yomwe mphamvu ya photovoltaic imaperekedwa kwathunthu, m'pofunika kukonza 1: 3 ku 1: 5 yosungirako mphamvu kuti mukwaniritse mphamvu zopanda mphamvu.Kuphatikiza kosungirako kwa Optical kukuyembekezeka kukhala njira yothetsera mphamvu yamtsogolo.
