Kusiyana pakati pa makina amagetsi a dzuwa olumikizidwa ndi gridi ndi makina osakhala ndi gridi

Mphamvu ya dzuwa ya photovoltaicmalo opangira magetsi amagawidwa m'magulu awirimachitidwe osakhala pa gridi (odziyimira pawokha)ndi makina olumikizidwa ndi gridi, ndipo tsopano ndikukuuzani kusiyana pakati pa ziwirizi: Ogwiritsa ntchito akasankha kukhazikitsa malo opangira magetsi a solar photovoltaic, choyamba ayenera kutsimikizira kugwiritsa ntchito malo opangira magetsi a solar photovoltaic omwe sali pa gridi kapena malo opangira magetsi a solar photovoltaic omwe ali ndi gridi, kugwiritsa ntchito ntchito ziwirizi sikofanana kwenikweni, ndithudi, kapangidwe ka malo opangira magetsi a solar photovoltaic sikofanana, mtengo wake nawonso ndi wosiyana kwambiri.

(1)Kupatula gridiMalo opangira magetsi a solar photovoltaic, omwe amadziwikanso kuti malo opangira magetsi a photovoltaic odziyimira pawokha, ndi makina omwe sadalira gridi yamagetsi ndipo amagwira ntchito pawokha. Amapangidwa makamaka ndi mapanelo amagetsi a solar photovoltaic, mabatire osungira mphamvu, zowongolera zoyatsira ndi kutulutsa, ma inverter ndi zida zina. Magetsi omwe amatulutsidwa ndi gulu lopangira magetsi a solar photovoltaic amalowa mwachindunji mu batri ndipo amasungidwa. Akafunika kupereka mphamvu yamagetsi, mphamvu yamagetsi mwachindunji mu batri imadutsa mu inverter ndipo imasinthidwa kukhala mphamvu yamagetsi ya 220V, yomwe ndi njira yobwerezabwereza ya mphamvu ndi kutulutsa. Mtundu uwu wa malo opangira magetsi a solar photovoltaic umagwiritsidwa ntchito kwambiri chifukwa sungalekeredwe ndi dera. Itha kuyikidwa ndikugwiritsidwa ntchito kulikonse komwe dzuwa limawala. Chifukwa chake, ndi yoyenera kwambiri kumadera akutali opanda gridi yamagetsi, zilumba zotalikirana, maboti osodza, malo oberekera akunja, ndipo ingagwiritsidwenso ntchito ngati zida zopangira magetsi mwadzidzidzi m'malo omwe magetsi amazima pafupipafupi.

Malo opangira magetsi a dzuwa omwe sagwiritsidwa ntchito pa gridi yamagetsi ndi 30-50% ya mtengo wa makina opangira magetsi chifukwa ayenera kukhala ndi mabatire. Ndipo nthawi yogwiritsira ntchito batire nthawi zambiri imakhala zaka 3-5, pambuyo pake iyenera kusinthidwa, zomwe zimawonjezera mtengo wogwiritsira ntchito. Ponena za zachuma, zimakhala zovuta kupeza njira zosiyanasiyana zolimbikitsira ndi kugwiritsa ntchito, kotero sizoyenera kugwiritsidwa ntchito m'malo omwe magetsi ndi abwino.

Komabe, ili ndi mphamvu yothandiza kwambiri m'mabanja omwe ali m'madera omwe magetsi sagwira ntchito kapena magetsi azimitsidwa pafupipafupi. Makamaka kuti muthetse vuto la kuunikira magetsi akatha, mutha kugwiritsa ntchito nyali zosungira mphamvu za DC, zomwe ndi zothandiza kwambiri. Chifukwa chake, malo opangira magetsi a dzuwa omwe si a grid ndi ogwiritsidwa ntchito makamaka m'malo omwe magetsi azimitsidwa pafupipafupi.

(2)Yolumikizidwa ndi gridiMalo opangira magetsi a dzuwa otchedwa photovoltaic amatanthauza kuti ayenera kulumikizidwa ku gridi yamagetsi ya anthu onse, zomwe zikutanthauza kuti malo opangira magetsi a dzuwa otchedwa photovoltaic, gridi yamagetsi yapakhomo ndi gridi yamagetsi ya anthu onse alumikizidwa pamodzi. Iyi ndi njira yamagetsi yamagetsi ya dzuwa yotchedwa photovoltaic yomwe iyenera kudalira gridi yamagetsi yomwe ilipo kuti igwire ntchito. Yopangidwa makamaka ndi gulu lamagetsi amagetsi a dzuwa la photovoltaic ndi inverter, gulu lamagetsi a dzuwa la photovoltaic lomwe limasinthidwa mwachindunji kukhala 220V-380V ndi inverter.

Mphamvu yosinthira imagwiritsidwanso ntchito popereka mphamvu ku zipangizo zapakhomo. Pamene magetsi opangidwa ndi dzuwa padenga akupanga magetsi ambiri kuposa omwe amagwiritsidwa ntchito ndi zipangizo, otsalawo amatumizidwa ku gridi ya anthu onse. Ngati mphamvu yochokera ku siteshoni yamagetsi ya photovoltaic yapakhomo singathe kukwaniritsa zosowa za zipangizo zapakhomo, imadzazidwanso yokha kuchokera ku gridi. Njira yonseyi imayendetsedwa mwanzeru, popanda kuyatsa kapena kuzimitsa kwa munthu.

Ngati mukufuna kudziwa zambiri za izi, dinani pakona yakumanja ya pansi, tidzakulumikizani posachedwa.
