Zigawo za photovoltaic system
1.PV system components PV system imakhala ndi zigawo zofunika zotsatirazi.Ma modules a Photovoltaic amapangidwa kuchokera ku maselo a photovoltaic kukhala mapepala owonda kwambiri omwe amaikidwa pakati pa encapsulation layer.Inverter ndikusintha mphamvu ya DC yopangidwa ndi gawo la PV kukhala mphamvu ya AC yolumikizidwa ndi grid.Batire ndi chipangizo chomwe chimasunga mphamvu zamagetsi mwachindunji (DC).Zokwera za Photovoltaic zimapereka chithandizo pakuyika ma module a PV.
2. Mitundu ya machitidwe a PV akhoza kugawidwa m'magulu awiri.Dongosolo lolumikizidwa ndi gridi: ubwino wa mtundu uwu wa dongosolo ndikuti palibe kusungirako kwa batri, kulumikizidwa mwachindunji ku gridi ya dziko lonse, musade nkhawa ndi kutha kwa magetsi;off-grid system: off-grid system imafuna batire kuti isunge mphamvu, motero mtengo wake udzakhala wokwera kwambiri.
Zitsanzo zamakina olumikizidwa ndi gridi ndi machitidwe akunja akuwonetsedwa poyerekeza:
Photovoltaic system wiring:
1. PV system series-parallel Connection PV modules ikhoza kugwirizanitsidwa mofanana kapena mndandanda malinga ndi zofunikira, ndipo imatha kulumikizidwa muzosakaniza zosakanikirana.Mwachitsanzo, ma module a 4 12V PV amagwiritsidwa ntchito popanga 24V off-grid system: 16 34V PV modules amagwiritsidwa ntchito popanga grid-connected system yomwe ili ndi magawo awiri.
2. Kulumikiza zigawo za inverter zitsanzo.Chiwerengero cha zigawo zomwe zingathe kuphatikizidwa pamitundu yosiyanasiyana ya ma inverters ndizotsimikizika, ndipo kuchuluka kwa maulumikizidwe a gulu lililonse la zigawo zitha kugawidwa molingana ndi kuchuluka kwa nthambi za inverter, monga momwe tawonetsera pachithunzichi:
3. Njira yolumikizira ma inverter ya DC yowononga dera ndi AC yophwanya dera iyenera kukhazikitsidwa pamagetsi a DC ndi AC yotulutsa inverter motsatana.Ngati pali gulu limodzi la ma inverters oti alumikizike nthawi imodzi, ma terminal a DC a gulu lililonse la inverters ayenera kulumikizidwa ndi gawo padera, ndipo ma terminal a AC amatha kulumikizidwa ndi gridi mofanana, ndi mainchesi a chingwe. ziyenera kukhuthala molingana.
4. Kulumikizana kwa gridi ya AC nthawi zambiri kumalumikizidwa ndi gululi ndi kampani yopangira magetsi, cholumikizira chimangofunika kusungitsa cholumikizira cha AC mu bokosi la mita, ndikuyika cholumikizira cholumikizira.Ngati mwiniwake sagwiritsa ntchito gululi kapena sanavomerezedwe kuti agwirizane ndi gridi.Kenako gawo loyika liyenera kulumikiza kumapeto kwa AC kumapeto kwenikweni kwa cholumikizira chamagetsi.Wogwiritsa ntchito adzafunika inverter ya magawo atatu ngati alumikizidwa ndi mphamvu yamagawo atatu.
Chigawo cha bracket:
Gulu la simenti lathyathyathya denga simenti lathyathyathya denga lathyathyathya akhoza kugawidwa m'magawo awiri, imodzi ndi gawo loyambira la bulaketi ndipo linalo ndi gawo la bulaketi.Maziko a bulaketi amapangidwa ndi konkriti ndi muyezo C30.Mabokosi opangidwa ndi opanga osiyanasiyana ndi osiyana, ndipo mabatani omwe amagwiritsidwa ntchito ndi osiyana malinga ndi zochitika zapadera za malo.Choyamba, ndikosavuta kumvetsetsa zida za bulaketi wamba komanso mawonekedwe a gawo lililonse kuti akhazikitse mwachangu mabakiti.
