Mashandiro anoita Dynamic Anti-Reverse Power Flow muResidential Solar Systems: Chidzidzo cheSystem Architecture

Nhanganyaya: Kubva padzidziso kuenda kuReal-World Anti-Reverse Power Flow Control

Mushure mekunzwisisa misimboti iri shurehapana kutumira kunze kwenyikauyekudzikamisa simba rinoshanduka, vagadziri vazhinji vemasystem vachiri kutarisana nemubvunzo unoshanda:

Sisitimu yemagetsi inodzivirira kudzoserwa kumashure inoshanda sei mukuisa simba rezuva remumba?

Muchokwadi, kufamba kwesimba rinodzivirira kudzoserwa kumashure hakugone kuitwa nemudziyo mumwe chete. Zvinodamagadzirirwo ehurongwa hwakarongekazvinosanganisira kuyera, kutaurirana, uye kudzora. Pasina dhizaini yesystem yakajeka, kunyangwe ma inverter akagadzirwa zvakanaka anogona kutadza kudzivirira kuburitswa kwegrid isina kurongerwa pasi pemamiriro ezvinhu anochinja-chinja ekutakura.

Chinyorwa chino chinopachidzidzo chemazuva ekugara chakajairika, ichitsanangura kuti kudzora simba rinorwisa kudzoserwa shure kunoshanda sei padanho resisitimu uye kuti seiKuyerwa kwesimba remagetsi panguva chaiyo panzvimbo yekubatanidza grid kwakakosha.

Mamiriro Ezvinhu Akajairika Ekugara Anoda Kudzora Kusadzokera Kumashure

Funga nezveimba yemhuri imwe chete ine zvinhu zvinotevera:

• Sisitimu yezuva yePV padenga

• Inverter yakabatana negrid

• Mitoro yemumba ine kuchinja-chinja kwakawanda

• Mitemo yemagetsi inorambidza kutengeswa kwemagetsi kunze kwenyika

Muzviitiko zvakadaro, kushandiswa kwemagetsi mumba kunogona kudzikira kamwe kamwe—semuenzaniso, kana midziyo yemagetsi yadzima—ukuwo kugadzirwa kwemagetsi ePV kuchiramba kwakakwira. Pasina simba rinochinja-chinja, simba rakawandisa richadzokera mugrid mukati memasekonzi.

Kudzivirira izvi kunodamhinduro dzinoramba dzichienderera mberi uye mhinduro dzinokurumidza, kwete static configuration.

Ongororo yeMagadzirirwo eSisitimu: Zvikamu Zvikuru

Sisitimu yemagetsi inorwisa kudzoserwa shure inowanzo kuve nezvikamu zvina zvinoshanda:

1. Grid Kuyera Rutivi

2. Chikamu chekutaurirana

3. Ronga Rondedzero Yezvinhu

4. Simba Rokugadzirisa Rutivi

Chikamu chimwe nechimwe chine basa rakakosha mukuchengetedza kutevedzera mitemo uye kugadzikana kwehurongwa.

Chikamu 1: Kuyerwa kweSimba reGridhi Munguva Yechokwadi

Pahwaro hwehurongwa ndipo panekuyerwa kwenguva chaiyo panzvimbo yekubatanidza kwakajairika (PCC).

Chiyero chemagetsi chakangwara chakaiswa pagrid connection chinogara chichiyera:

• Simba rinopinzwa kunze kwenyika

• Simba rinotumirwa kunze kwenyika

• Kutungamira kwesimba remagetsi

Chiyero ichi chinofanira kunge chiri:

• Zvakarurama

• Kuenderera mberi

• Kukurumidza zvakakwana kuratidza shanduko dzemutoro

Pasina data iri, sisitimu haigone kuona kana kuyerera kwesimba rekudzokera shure kuri kuitika.

Chikamu chechipiri: Kutaurirana Pakati peMeter neControl System

Ruzivo rwekuyera runofanira kutumirwa kune system yekudzora pasina kunonoka kushoma.

Nzira dzakajairika dzekutaurirana dzinosanganisira:

• WiFikune network dzekugara

• MQTTyekubatanidzwa nehurongwa hwekutonga simba

• Zigbeeyezvivakwa zvepagedhi remunharaunda

Kutaurirana kwakasimba kunoita kuti mhinduro yesimba isvike pakudzora panguva chaiyo.

Chikamu 3: Kudzora Pfungwa uye Kugadzira Sarudzo

Sisitimu yekudzora—inoshandiswa mu inverter controller kana sisitimu yekutarisira simba—inoramba ichiongorora mhinduro yesimba regrid.

Pfungwa dzakajairika dzinosanganisira:

• Kana kuendesa kunze kwenyika > 0 W → deredza kubuda kwePV

• Kana kuendesa kunze > chiyero → bvumira PV kuwedzera

• Isa zvinyoro nyoro kudzivirira kuzunguzika

Pfungwa iyi inoramba ichienderera mberi, ichiumbasisitimu yekudzora yakavharika.

Chikamu chechina: Kugadziriswa kwePV Output

Zvichibva pasarudzo dzekudzora, inverter inogadzirisa simba rePV rinobuda:

• Kuderedza kugadzirwa panguva yekuremerwa kwakaderera

• Kuwedzera kwezvinobuda kana zvinodiwa nemhuri zvichikwira

• Kuchengetedza kuyerera kwesimba regrid pazero kana kuti pedyo nezero

Kusiyana nemagadzirirwo ekusatumira zvinhu kunze kwenyika asingachinji, nzira iyi inobvumira sisitimu kupindura mamiriro ezvinhu chaiwo.

Pakakodzera Meter yesimba rakangwara: Basa rePC321

Mukuvaka uku,PC321mita yesimba yakangwarainoshanda sechibatiso chekuyera chehurongwa hwese.

PC321 inopa zvinotevera:

• Kuyerwa kwegrid inopinzwa uye inotengeswa kunze kwenyika panguva chaiyo

• Kugadziriswa kwedata nekukurumidza kwakakodzera marobho ekudzora ane simba

• Kutaurirana kuburikidza neWiFi, MQTT, kana Zigbee

• Nguva yekupindura inokwanisa kutsigirakugadziriswa kwesimba remasekonzi maviri

Nekupa mhinduro chaiyo yemagetsi egrid, PC321 inoita kuti sisitimu yekudzora ikwanise kudzora kubuda kwePV nemazvo—ichidzivirira kuyerera kwemagetsi kubva pakudzokera shure pasina kuderedza kugadzirwa kwezuva zvisina kufanira.

Chinokosha ndechekuti PC321 haiite control ye inverter pachayo. Asi, inoita kuti inverter ishande.inogonesa kudzora kwakavimbika nekupa data rekuyera iro sarudzo dzese dzepamusoro dzinovimba naro.

Nei Kutengesa Zvinhu Zvisingachinji Kuchiwanzokundikana Mudzimba Chaidzo

Munzvimbo dzekugara chaidzo, kuchinja kwemitoro hakugone kufungidzirwa:

• Midziyo inobatidzwa nekudzima

• Macharger emagetsi anotanga kamwe kamwe

• Mapombi ekupisa uye magadzirirwo eHVAC system

Magadzirirwo e "static inverter-based zero-export" haagone kupindura nekukurumidza kuzviitiko izvi. Mhedzisiro yacho ndeiyi:

• Kutumira kunze kwegrid kwenguva pfupi

• Kuderedzwa kwakanyanya kwePV

Kudzora kwakasimba, kunobva pamita kunopa mhinduro yakagadzikana uye inoshanda.

Kufunga Nezvekushandiswa Kwenzvimbo Dzekugara Dzinodzivirira Kudzokera Kumashure

Paunenge uchigadzira sisitimu yemagetsi inoshandura simba inodzivirira kudzoserwa shure, funga nezve:

• Nzvimbo yekuisa mita paPCC

• Kuvimbika kwekutaurirana pakati pemidziyo

• Nguva yekupindura kwe loop yekudzora

• Kuenderana nemapuratifomu e inverter kana EMS

Magadzirirwo akagadzirwa zvakanaka anovimbisa kutevedzera mitemo pasina kukanganisa kushandiswa kwesimba.

Mhedziso: Zvivakwa Zvinokosha Kupfuura Zvishandiso Zvega

Kudzora kuyerera kwesimba kunopesana nekudzokera shurehazvigoneke nekumisa kugadzirwa kwezuva. Izvi zvinokonzerwa nemagadzirirwo ehurongwa akarongeka zvakanakauko kuyera, kutaurirana, uye kudzora zvinoshanda pamwe chete panguva chaiyo.

Sezvo masisitimu ePV ekugara achiwedzera kushanda,Mamita emagetsi akangwara ari pagrid interface ave chinhu chakakoshanzira dzinoshanda dzekudzivirira kutenderera kwesimba remagetsi.

Kune mapurojekiti ezuva ekugara anoda kudzora kutengesa kunze kwenyika nemazvo, kunzwisisa magadzirirwo esisitimu ndiyo nhanho yekutanga yekuisa magetsi munzvimbo dzakagadzikana uye dzinoenderana nezvinodiwa.
