Maonekedwe Olumikizidwa ndi Gridi ndi Chitsimikizo cha Chitetezo cha Ma Solar PV Inverters

Maboma ndi makampani opanga magetsi padziko lonse lapansi akuyembekeza kuti kupanga magetsi a photovoltaic kudzakhala ndi gawo lalikulu pakupereka mphamvu zamtsogolo. Kutembenuza magetsi achindunji (DC) opangidwa ndi ma cell a solar kukhala alternating current (AC) omwe amatha kuphatikizika mu gridi sikubweretsa vuto laukadaulo komanso kumapangitsa kuti okonza azitha kukhwimitsa zinthu. Ma inverters a PV amayenera kuchita bwino pamitundu yosiyanasiyana yamagetsi ndi malo ogwirira ntchito pomwe amatsatira mosamalitsa miyezo yachitetezo.

Malingaliro a Kamangidwe ndi Mapangidwe

Photovoltaic inverter design iyenera kuyika patsogolo kutembenuka kwamphamvu kwamphamvu ndikuwonetsetsa chitetezo chadongosolo. Kuyeza mphamvu zenizeni ndi chinthu chofunikira kwambiri pakupititsa patsogolo ntchito ya inverter. Kuti athandizire kusinthika kwaukadaulo wa Photovoltaic, opanga ma inverter ayenera kugwirira ntchito limodzi ndi opanga masensa kuti apange zinthu zomwe zikugwirizana ndi zomwe zaposachedwa.

Kupititsa patsogolo Mphamvu Zopangira Mphamvu

Kuti mutsegule mphamvu zonse zamakina a PV, zoyeserera ziyenera kuyang'ana kwambiri pakukweza mphamvu zamagetsi kuti muchepetse ndalama. Pakadali pano, opanga ma cell a solar akuyesetsa kukulitsa mphamvu yosinthira kuwala kwa magetsi, pomwe opanga ma inverter a PV amayang'ana kwambiri kupanga ma inverter am'badwo wotsatira omwe amaphatikiza zowunikira ndi zina zanzeru kuti apititse patsogolo mphamvu ndikuchita bwino. Ukadaulo wa zingwe zambiri umayimira zomwe zikuchitika, zomwe zimapangitsa kuti chingwe chilichonse cha cell chizikhala ndi chipangizo chodziyimira pawokha cha Maximum Power Point Tracking (MPPT), potero kumapangitsa kuti mphamvu zitheke.

Njira Zochitetezera

Ngakhale mapangidwe opanda ma transformer amathandizira kuchepetsa ndalama ndikuwongolera magwiridwe antchito, amabweretsanso zovuta zina zachitetezo. Mwachitsanzo, zotulutsa za inverter zitha kukhala ndi zida za DC chifukwa cha zinthu monga kusintha kwa IGBT molakwika. Chifukwa chake, masensa enieni apano akuyenera kuphatikizidwa pakupanga kuti achepetse kutsika ndi kugwedezeka, kuwonetsetsa kutsata malire okhwima a jakisoni a DC m'maiko onse. Kuphatikiza apo, kupewa kutayikira kwapansi ndikofunikira, komwe kumachitika pogwiritsa ntchito zida zotsalira (RCDs) kapena njira zofananira zama sensor kuti muteteze dongosolo.

Pamene teknoloji ikupita patsogolo, mapangidwe a photovoltaic inverter akuyembekezeka kukhala ovuta kwambiri. Mwachitsanzo, malire omwe amavomerezedwa padziko lonse lapansi pa kupotoza kwathunthu kwa ma harmonic (THD) a ma inverter otuluka akhoza kutuluka. Izi zimafunikira kuyeza kolondola kwapano ngakhale pama frequency apamwamba kwambiri kuposa ma gridi wamba. Kulimbitsa mgwirizano pakati pa opanga ma inverter ndi opanga masensa kumatha kuyala maziko aukadaulo waukadaulo, potero kukhala ndi mpikisano wampikisano womwe ukukula mwachangu.

Mwachidule, poyang'anizana ndi msika womwe ukukulirakulira wa solar, mapangidwe a ma inverters a photovoltaic sayenera kungochita bwino komanso kuonetsetsa chitetezo chokwanira. Kupyolera muzochitika zamakono zamakono komanso mgwirizano wamakampani, tikhoza kuyembekezera kuwona ma inverters a photovoltaic anzeru, odalirika, komanso ogwira mtima kwambiri.
