Kodi pali kusiyana kotani pakati pa inverter yosungirako mphamvu ndi photovoltaic inverter?

Monga chigawo chachikulu chakupanga mphamvu ya photovoltaicndi machitidwe osungira mphamvu, ma inverters ndi otchuka.Anthu ambiri amawona kuti ali ndi dzina lofanana ndi gawo lomwelo ndipo amaganiza kuti ndi mtundu womwewo wa mankhwala, koma izi sizili choncho.

Chithunzi ma voltaics ndi ma inverters osungira mphamvu sikuti ndi "othandizana nawo bwino kwambiri", komanso amasiyana pamagwiritsidwe ntchito monga ntchito, kuchuluka kwa magwiritsidwe, ndi ndalama.

Inverter yosungirako mphamvu

Mphamvu yosungirako mphamvu (PCS), yomwe imadziwikanso kuti "bidirectional energy storage inverter", ndiye gawo lalikulu lomwe limazindikira njira ziwiri za mphamvu yamagetsi pakati pa makina osungira mphamvu ndi gridi yamagetsi.Amagwiritsidwa ntchito kuwongolera njira yolipirira ndi kutulutsa batire ndikusintha ma AC ndi DC.Sinthani.Ikhoza kupereka mphamvu mwachindunji ku katundu wa AC pamene palibe gridi yamagetsi.

1. Mfundo zoyendetsera ntchito

Malinga ndi zochitika zomwe zimagwiritsidwa ntchito komanso mphamvu zosinthira mphamvu zosungiramo mphamvu, zosinthira mphamvu zosungiramo mphamvu zimatha kugawidwa kukhala zosinthira zosakanizidwa za photovoltaic, zosinthira zamagetsi zazing'ono, zosinthira mphamvu zosungira mphamvu zapakati, ndi zosinthira zosungira mphamvu zapakati.makina oyenda, etc.

Photovoltaic energy storage hybrid ndi zosinthira mphamvu zochepa zosungira mphamvu zimagwiritsidwa ntchito pazochitika zapakhomo ndi mafakitale ndi zamalonda.Mphamvu zamagetsi za Photovoltaic zitha kugwiritsidwa ntchito ndi katundu wamba poyamba, ndipo mphamvu zochulukirapo zimasungidwa mu batri.Pamene akadali owonjezera mphamvu, akhoza kusankha pamodzi.mu gridi.

Mphamvu zapakati, zosinthira mphamvu zosungiramo mphamvu zapakati zimatha kupeza mphamvu zowonjezera ndipo zimagwiritsidwa ntchito m'mafakitale ndi malonda, malo opangira magetsi, ma gridi akuluakulu amagetsi ndi zochitika zina kuti akwaniritse kumeta nsonga, kudzaza zigwa, kumeta nsonga / kusinthasintha pafupipafupi ndi ntchito zina.

2. Kuchita mbali yofunika kwambiri pazambiri zamafakitale

Electro Makina osungira mphamvu zamagetsi nthawi zambiri amakhala ndi magawo anayi oyambira: batire, dongosolo loyang'anira mphamvu (EMS), inverter yosungira mphamvu (PCS), ndi dongosolo loyang'anira mabatire (BMS).

Inverter yosungiramo mphamvu imatha kuwongolera njira yolipirira ndi kutulutsamphamvu yosungirako batire paketindikusintha AC kukhala DC, yomwe imagwira ntchito yofunika kwambiri pamakina ogulitsa mafakitale.

Kumtunda: zida za batri, othandizira zida zamagetsi, etc.;

Midstream: ophatikiza makina osungira mphamvu ndi okhazikitsa dongosolo;

Mapeto a ntchito yotsika: malo opangira magetsi a mphepo ndi photovoltaic,machitidwe a gridi yamagetsi, nyumba / mafakitale ndi malonda, ogwira ntchito zoyankhulirana, malo opangira deta ndi ena ogwiritsa ntchito mapeto.

Photovoltaic inverter

Photovoltaic inverter ndi inverter yoperekedwa kumunda wamagetsi opangira mphamvu ya solar photovoltaic.Ntchito yake yayikulu ndikusinthira mphamvu ya DC yopangidwa ndi ma cell a solar kukhala mphamvu ya AC yomwe imatha kuphatikizidwa mwachindunji mu gridi ndikunyamula kudzera muukadaulo wosinthira mphamvu zamagetsi.

Monga chipangizo cholumikizira pakati pa maselo a photovoltaic ndi gridi yamagetsi, photovoltaic inverter imasintha mphamvu ya maselo a photovoltaic kukhala mphamvu ya AC ndikutumiza ku gridi yamagetsi.Zimagwira ntchito yofunika kwambiri pamagetsi opangira magetsi a photovoltaic grid.

Ndi kukwezedwa kwa BIPV, kuti muwonjezere kutembenuka kwamphamvu kwa mphamvu ya dzuwa ndikuganizira mawonekedwe okongola a nyumbayo, zofunikira za mawonekedwe a inverter zimasiyanitsidwa pang'onopang'ono.Pakalipano, njira zodziwika bwino za solar inverter ndi: centralized inverter, string inverter, multi-string inverter ndi component inverter (micro-inverter).

Zofanana ndi Kusiyana pakati pa Kuwala / Kusungirako Inverters

"Mnzanu Wabwino Kwambiri": Ma photovoltaic inverters amatha kupanga magetsi masana okha, ndipo mphamvu zomwe zimapangidwira zimakhudzidwa ndi nyengo ndipo zimakhala zosayembekezereka komanso zina.

The mphamvu yosungirako Converter akhoza mwangwiro kuthetsa mavutowa.Pamene katundu ali otsika, linanena bungwe mphamvu ya magetsi amasungidwa mu batire.Pamene katunduyo ali pachimake, mphamvu yamagetsi yosungidwa imatulutsidwa kuti ichepetse kupanikizika pa gridi yamagetsi.Gridi yamagetsi ikalephera, imasinthira ku off-grid mode kuti ipitilize kupereka mphamvu.

Kusiyana kwakukulu: Kufunika kwa ma inverters muzochitika zosungira mphamvu kumakhala kovuta kwambiri kusiyana ndi zochitika zolumikizidwa ndi grid photovoltaic.

Kuphatikiza pa kutembenuka kwa DC kupita ku AC, ikufunikanso kukhala ndi ntchito monga kutembenuka kuchokera ku AC kupita ku DC ndikusintha mwachangu kuchokera pagululi.Panthawi imodzimodziyo, PCS yosungirako mphamvu imakhalanso yosinthira bidirectional yokhala ndi mphamvu zoyendetsera mphamvu zonse poyendetsa ndi kutulutsa.

Mwanjira ina, ma inverters osungira mphamvu ali ndi zotchinga zapamwamba zaukadaulo.

Kusiyana kwina kumawonekera mu mfundo zitatu izi:

1. Mlingo wodzigwiritsira ntchito wamtundu wa photovoltaic inverters ndi 20% yokha, pamene chiwerengero chodzigwiritsira ntchito cha otembenuza mphamvu zosungiramo mphamvu ndi 80%;

2. Pamene mains mphamvu akulephera, ndiphotovoltaic grid-yolumikizidwa inverteryalumala, koma chosinthira chosungira mphamvu chikhoza kugwirabe ntchito bwino;

3. Pankhani ya kuchepetsedwa kosalekeza kwa zothandizira zothandizira magetsi opangidwa ndi gridi, ndalama zogulitsira mphamvu zosungiramo mphamvu ndizoposa za photovoltaic inverters.
