Sida loogu rakibo Mitirrada Korontada-ka-hortagga-reverse (Zero-Dhoofinta) ee Nidaamyada PV - Hage Dhamaystiran

Hordhac

Sida korsashada sawir-qaadista (PV) ay dardargelinayso, mashaariic badan ayaa soo food saartayshuruudaha dhoofinta eber. Tas-hiilaadka inta badan waxa ay mamnuucaan tamarta cadceedda ee xad dhaafka ah in ay dib ugu soo laabato shabkada, gaar ahaan aagagga leh transformers buuxa, lahaanshaha aan caddayn ee xuquuqaha isku xidhka shabakada, ama xeerarka tayada tayada adag. Hagahan waxa uu sharxayaa sida loo rakiboka-hortagga (eber-dhoofin) mitir koronto, xalalka asaasiga ah ee la heli karo, iyo habeynta saxda ah ee cabbirrada nidaamka PV kala duwan iyo codsiyada.

1. Tixgelinta Muhiimka ah Kahor Rakibaadda

Xaaladaha qasabka ah ee dhoofinta eber

• Dheefta beddelka: Marka transformers-ka maxaliga ahi ay ku shaqaynayaan awood sare, awooda rogan waxay sababi kartaa culays xad dhaaf ah, jaban, ama qalab la'aan.

• Is-isticmaalka oo kaliya (wax dhoofinta xad-dhaaf ah lama oggola)Mashruucyada aan lahayn ogolaanshaha quudinta xadhkaha goosashada waa in ay cunaan dhammaan tamarta laga dhaliyo gudaha.

• Ilaalinta tayada awooddaAwoodda rogaal celiska ah ayaa laga yaabaa inay soo bandhigto qaybaha DC, iswaafajinta, ama culaysyada aan dheeli tirnayn, hoos u dhigida tayada xadhkaha.

Liiska hubinta Rakibaadda ka hor

• Ku habboonaanta aaladda: Hubi in awoodda mitirka lagu qiimeeyay ay la mid tahay cabbirka nidaamka PV (hal-waji ≤8kW, saddex-waji>8kW). Hubi isgaadhsiinta beddelka (RS485 ama wax u dhigma).

• Deegaanka: Ku rakibida bannaanka, u diyaari xeryo aan cimiladu lahayn. Nidaamyada rogrogayaasha badan, u qorshee fiilooyinka baska RS485 ama xog-ururinta xogta Ethernet.

• U hoggaansanaanta iyo badbaadada: Xaqiiji barta isku xirka shabakada ee utility, oo hubi in baaxadda culeysku uu la mid yahay jiilka PV ee la filayo.

2. Xuddunta Xalka Zero-Dhoofinta

Xalka 1: Xadaynta Awoodda iyada oo loo marayo Xakamaynta Inverter

• Mabda'a: Mitirka smart wuxuu cabbiraa jihada wakhtiga-dhabta ah. Marka la ogaado socodka rogaal celiska ah, mitirku wuxuu la xidhiidhaa RS485 (ama hab-maamuusyada kale) ee rookaha, kaas oo yareynaya awoodda wax soo saarka ilaa dhoofinta = 0.

• Isticmaal kiisaska: Aagagga is beddelka-isku-dhafan, mashaariicda is-isticmaalka oo leh culeysyo deggan.

• Faa'iidooyinka: Fudud, qiimo jaban, jawaab degdeg ah, looma baahna kaydinta.

Xalka 2: Nuugista Xamuulka ama Isku-dhafka Kaydka Tamarta

• Mabda'a: Mitirku wuxuu ilaaliyaa hadda meesha isku xirka grid. Halkii la xadidi lahaa soosaarka rogaha, awooda xad dhaafka ah waxaa loo weeciyaa habka kaydinta ama qashinka lagu daadiyo (tusaale, kuleyliyaha, qalabka warshadaha).

• Isticmaal kiisaskaMashruucyo leh culeysyo kala duwan, ama halka sareynta jiilka PV ay tahay mudnaanta.

• Faa'iidooyinkaDib-u-celinta waxay ku sii jiraan qaabka MPPT, tamarta lama lumin, nidaamka sare ee ROI.

3. Muuqaallada Rakibaadda ee Cabbirka Nidaamka

Nidaamyada Hal-rogayaasha ah (≤100 kW)

• Habaynta: 1 inverter + 1 mitir laba jiho ah.

• Booska mitirka: Inta u dhaxaysa wax soo saarka AC inverter iyo jabiyaha ugu weyn. Waa in aan rar kale lagu xidhin inta u dhaxaysa.

• Dalabka xargaha: PV rogayaasha → Transformers hadda (haddii la isticmaalo) → Mitir korantada smart → Jabiyaha ugu weyn

• macquul: Mitirku waxa uu cabbiraa jihada iyo awoodda, ka bacdi inverter-ku waxa uu hagaajiyaa wax soo saarka si uu u dhigmo culayska.

• Faa'iidada: Xadhkaha fudud, kharash yar, jawaab degdeg ah.

Nidaamyada is beddelka badan (> 100 kW)

• Habaynta: rogayaal badan + 1 mitir koronto smart + 1 xog ururiye.

• Booska mitirka: Marka la eego barta isku xirka shabakadaha guud (dhammaan wax soo saarka rogaha oo la isku daray).

• Xadhkaha goosashada: Wax soo saarka beddelka → Busbar → mitirka laba jiho → xog-ururinta → jabiyaha ugu weyn → Koronto/Loads.

• macquul: Xoog-ururinta xogta ayaa ururisa xogta mitirka oo u qaybisa amarada mid kasta oo rogrogay si siman.

• Faa'iidada: La cabbiri karo, kantarool dhexe, jaangooyooyin cabbir dabacsan.

4. Rakibaadda Noocyo Mashruuc oo kala duwan

Is-isticmaalka Kaliya Mashaariicda

• Shuruudaha: Lama oggola dhoofinta xadhkaha goosashada

• Booska mitirka: Inta u dhaxaysa wax soo saarka AC inverter iyo load jebiya maxalliga ah. Ma jiro dareemaha isku xirka shabakadaha la isticmaalo

• Hubi: Tijaabi hoos jiil buuxa oo aan lahayn wax rar ah - inverter waa inuu hoos u dhigaa tamarta eber.

Mashaariicda Saturation Transformer

• Shuruudaha: Xidhiidhka khadka waa la oggol yahay, laakiin dib u celi awoodda si adag waa mamnuuc.

• Booska mitirkaInta u dhaxaysa wax-soo-saarka inverter-ka iyo isku-xidhka isku xirka.

• macquul: Haddii korontadu dib loo ogaado, beddelaadaha ayaa xaddidaya wax soo saarka; kayd ahaan, jabiyayaashu way go'i karaan si ay uga fogaadaan diiqad beddelka.

Is-isticmaalka Dhaqanka + Mashaariicda Dhoofinta Xariirka

• ShuruudahaDhoofinta waa la oggol yahay, laakiin xaddidan.

• Habaynta mitirka: Mitirka ka-hortagga rogaal-celinta ayaa si taxane ah loogu rakibay mitirka biilasha ee labada jiho.

• macquul: Mitirka-ka-hortagga ayaa ka hortagaya dhoofinta; Kaliya haddii ay dhacdo guuldarro ayaa mitirka utility-ga ayaa diiwaan gelisa soo gelidda.

5. FAQs

Q1: Miyuu mitirku laftiisa joojiyaa socodka gadaasha?
Maya. Mitirku wuxuu cabbiraa jihada korantada oo ka warbixisa. Qalabeeyaha ama kontaroolaha ayaa fulinaya ficilka.

Q2: Sidee ugu dhakhsaha badan ee nidaamku uga falcelin karaa?
Caadi ahaan 1-2 ilbidhiqsi gudahood, taas oo ku xidhan xawaaraha isgaadhsiinta iyo qalabka rogaha.

Q3: Maxaa dhacaya inta lagu jiro cilladda shabakadu?
Isgaarsiinta maxalliga ah (RS485 ama kontoroolka tooska ah) waxay hubisaa ilaalinta joogtada ah xitaa internet la'aan.

Q4: Mitirradani ma ku shaqayn karaan nidaamyada weji-kala-qaybsan (120/240V)?
Haa, moodooyin gaar ah ayaa loo qaabeeyey in ay wax ka qabtaan isku xidhka wejiga kala qaybsan ee laga isticmaalo Waqooyiga Ameerika.
