Iyadoo horumarinta degdega ah ee warshadaha sawir-qaadista, awoodda la rakibay ayaa sii kordheysa.Meelaha qaarkood, awoodda la rakibay ayaa buuxsantay, iyo nidaamyada cusub ee qoraxda lagu rakibay ma awoodaan inay ku iibiyaan koronto internetka.Shirkadaha grid waxay u baahan yihiin in ku xidhidhiyahaNidaamyada PVla dhisay mustaqbalka ha noqdaan nidaamyo koronto oo aan dib u soconayn.
Waa maxay Counterflow?
Waa maxay isbeddelka hadda?Nidaamka PV, tamarta korantada waxaa guud ahaan laga keenaa shabagga ilaa culeyska, kaas oo loo yaqaan hadda hore.Marka nidaamka PV la rakibo, haddii awoodda nidaamka PV ay ka weyn tahay awoodda culeyska maxalliga ah, awoodda aan la isticmaalin ayaa loo diraa shabkada.Maadaama jihada hadda socota ay ka soo horjeedo kan hadda jira, tan waxaa loo yaqaan 'reverse current'.Mitirka laba-jidka ah ee ku xidhan xadhkaha goostay, awooda hore waa awooda laga keenay shabkada ilaa culayska, awooda rogantuna waa awooda laga keenay nidaamka PV ilaa xadhkaha.Nadaamka PV dhabarka lagu shubo macneheedu waa in awooda uu dhaliyo PV loo isticmaali karo rarka gudaha oo kaliya oo aan loo dhoofin karin shabkada.
Marka rookaha PV u beddelo dhibcaha DC ee ay abuureen cutubyada PV awood AC, waxaa jira qaybo ka mid ah DC iyo iswaafajinta, dheelitir la'aanta hadda jirta iyo hubanti la'aanta awoodda wax soo saarka.Marka korantada la dhaliyo lagu shubo shabkada dadweynaha, waxay u keenaysaa wasakh iswaafajin ah shabkada, taas oo si fudud u sababi karta in korantada shabkada ay isbeddesho oo ay liidato.Haddii ay jiraan ilo-koronto oo badan oo sidan oo kale ah oo ku quudinaya korantada shabkada, tayada korontadu aad bay u hoos u dhacaysaa.Sidaa darteed, nidaamka koronto-dhaliyaha noocan ah ee sawir-qaadista waa in lagu qalabeeyaa aaladaha ilaalinta beddelka ee hadda jira si looga hortago dhacdada hadda socota.
Sidee looga hortegi karaa rogaal celiska hadda?
Dib-u-celintamabda'a shaqada ee hadda: Ku rakib alid ku ahmitirka hadda ama dareemayaasha hadda ee barta isku xirka shabagga.Marka ay ogaato qulqulka hadda socda ee shabkada, waxa ay u dirtaa ishaareeyaha isgaadhsiinta 485, inverter-ku waxa uu yareeyaa awoodda wax-soo-saarka ilaa uu hadda wax-soo-saarku noqonayaa eber.Tani waxay xaqiijinaysaalid ku ahshaqada hadda.Marka loo eego heerarka tamarta kala duwan ee nidaamka, nidaamka PV waxaa loo qaybin karaa hal-wajilid ku ahnidaamka hadda jira iyo saddex wejilid ku ahnidaamka hadda jira.
Sida loo doortolid ku ahmitirka smart ee hadda jira?
Marka korontadda PV ay ka weyn tahay baahida culeyska, awoodda gadaal ayaa la soo saarayaa.Waxaan u baahanahay mitir si aan u ogaano oo aan u go'aamino wax soo saarka tamarta firfircoon ee rookaha, ka dibna mitirku wuxuu soo diraa calaamad isagoo isticmaalaya isgaadhsiinta RS485 si uu ula falgalo xogta inverter si loo habeeyo awoodda wax soo saarka ee inverter si loo dheellitiro awoodda wax soo saarka iyo korontada.
Saxsanaanta: Dooro mitir caqli-gal ah oo si sax ah u cabbiraya isticmaalka koronto ee taban iyo togan.Waa inay ahaataa mid aad sax u ah si loo xaqiijiyo biilasha saxda ah iyo la socodka.
Waafaqid: Hubi in mitirka smart uu ku habboon yahay nidaamkaaga korantada iyo shuruudaha tamarta.Waa inay si aan kala go 'lahayn ula shaqeyso kaabayaashaaga jira oo ay awood u yeelato inay ku xidho nidaamka cabbiraadda tamarta.
Hab-maamuuska isgaarsiinta: Hubi in mitirka smart uu taageeray borotokoolka isgaarsiinta ee ku habboon shabakada tamarta.Nidaamyada caadiga ah waa Modbus, DLMS/COSEM iyo Zigbee.
Maamulka xogta: Tixgeli awoodaha maaraynta xogta ee mitirka smart.Waa inay haysataa meel kaydin ku filan iyo awooda lagu wareejinayo xogta hab dhexe oo biilasha iyo falanqaynta ah.Raadi mitiro bixiya sirta xogta iyo gudbinta sugan.
