Chiyambi: Kukwera kwa Balcony PV ndi Vuto la Mphamvu Yobwerera M'mbuyo
Kusintha kwa dziko lonse lapansi pankhani yochotsa mpweya woipa m'nyumba kukulimbikitsa kusintha kwamphamvu kwa nyumba: makina a photovoltaic pa khonde (PV). Kuyambira "mafakitale ang'onoang'ono" m'mabanja aku Europe mpaka misika yatsopano padziko lonse lapansi, ma PV pa khonde akupatsa mphamvu eni nyumba kuti akhale opanga mphamvu.
Komabe, kugwiritsa ntchito mwachangu kumeneku kumabweretsa vuto lalikulu laukadaulo: kusintha kwa magetsi. Pamene makina a PV apanga magetsi ambiri kuposa omwe banja limagwiritsa ntchito, magetsi ochulukirapo amatha kubwerera ku gridi ya anthu onse. Izi zingayambitse:
- Kusakhazikika kwa Gridi: Kusinthasintha kwa magetsi komwe kumasokoneza mphamvu ya m'deralo.
- Ngozi Zachitetezo: Ngozi kwa ogwira ntchito zamagetsi omwe sangayembekezere ma circuits amoyo ochokera pansi pa mtsinje.
- Kusatsatira Malamulo: Mabungwe ambiri opereka chithandizo amaletsa kapena kulanga kulowetsedwa kwa gridi kosaloledwa.
Apa ndi pomwe njira yanzeru yotetezera mphamvu ya Reverse, yomwe imayang'ana kwambiri chipangizo chowunikira bwino kwambiri monga ZigBee Power Clamp, imakhala yofunika kwambiri pa dongosolo lotetezeka, logwirizana, komanso logwira ntchito bwino.
Yankho Lofunika Kwambiri: Momwe Dongosolo Lotetezera Mphamvu Yobwerera Limagwirira Ntchito
Dongosolo loteteza mphamvu yobwerera m'mbuyo ndi kuzungulira kwanzeru.Chida cha ZigBee Power Clampamagwira ntchito ngati "maso," pomwe chipata cholumikizidwa ndi chowongolera cha inverter zimapanga "ubongo" womwe umachitapo kanthu.
Mfundo Yogwirira Ntchito Mwachidule:
- Kuwunika Nthawi Yeniyeni: Cholumikizira chamagetsi, monga chitsanzo cha PC321, chimayesa nthawi zonse komwe magetsi akuyenda komanso kukula kwa malo olumikizirana ndi gridi pogwiritsa ntchito zitsanzo zachangu kwambiri. Chimatsata magawo ofunikira monga Current (Irms), Voltage (Vrms), ndi Active Power.
- Kuzindikira: Kumazindikira nthawi yomweyo pamene mphamvu ikuyamba kuyendakuchokeranyumbatogridi.
- Chizindikiro ndi Kulamulira: Chotsekeracho chimatumiza deta iyi kudzera mu protocol ya ZigBee HA 1.2 kupita ku chipata chogwirizana ndi makina oyendetsera nyumba kapena makina oyendetsera mphamvu. Kenako makinawo amatumiza lamulo ku inverter ya PV.
- Kusintha kwa Mphamvu: Inverter imachepetsa mphamvu yake yotulutsa mphamvu kuti igwirizane ndi momwe nyumbayo imagwiritsidwira ntchito nthawi yomweyo, ndikuchotsa njira iliyonse yobwerera m'mbuyo.
Izi zimapangitsa kuti pakhale njira ya "Zero Export", kuonetsetsa kuti mphamvu zonse za dzuwa zimagwiritsidwa ntchito m'deralo.
Zinthu Zofunika Kuziganizira Mu Njira Yabwino Yowunikira
Mukasankha chipangizo chowunikira chachikulu cha mapulojekiti anu a PV a pa khonde, ganizirani zinthu zofunika kwambiri izi kutengera luso la PC321 Power Clamp.
Mafotokozedwe Aukadaulo Mwachidule:
| Mbali | Kufotokozera ndi Chifukwa Chake Kuli Kofunika |
|---|---|
| Pulogalamu Yopanda Waya | ZigBee HA 1.2 - Imathandizira kuphatikiza bwino komanso kokhazikika ndi nsanja zazikulu zoyendetsera nyumba ndi mphamvu kuti zizitha kulamulira bwino. |
| Kulondola Kolinganizidwa | < ± 1.8% ya kuwerenga - Kumapereka deta yodalirika mokwanira kuti ipange zisankho zolondola zowongolera ndikuwonetsetsa kuti palibe kutumiza kulikonse. |
| Zosinthira Zamakono (CT) | Zosankha za 75A/100A/200A, Kulondola < ± 2% - Kusinthasintha pa kukula kosiyanasiyana kwa katundu. Ma CT okhala ndi pulagi, okhala ndi mitundu amaletsa zolakwika za mawaya ndi nthawi yoyika slash. |
| Kugwirizana kwa Gawo | Makina amodzi ndi atatu - Amagwiritsidwa ntchito m'njira zosiyanasiyana m'nyumba. Kugwiritsa ntchito ma CT atatu pa gawo limodzi kumalola kuti pakhale tsatanetsatane wa katundu. |
| Magawo Oyezedwa Ofunika | Mphamvu Yamagetsi (Irms), Voltage (Vrms), Mphamvu Yogwira Ntchito & Mphamvu, Mphamvu Yogwira Ntchito & Mphamvu - Deta yonse yowunikira ndi kulamulira dongosolo lonse. |
| Kukhazikitsa ndi Kupanga | Sitima yaing'ono ya DIN-Rail (86x86x37mm) - Imasunga malo m'mabolodi ogawa. Yopepuka (435g) komanso yosavuta kuyiyika. |
Kupitilira pa Tsamba Lofotokozera:
- Chizindikiro Chodalirika: Njira yogwiritsira ntchito antenna yakunja imatsimikizira kulumikizana kwamphamvu m'malo ovuta kukhazikitsa, zomwe ndizofunikira kwambiri kuti pakhale kuzungulira kokhazikika kwa control.
- Kuzindikira Zomwe Zikuchitika: Kutha kuyang'anira magawo monga Reactive Power kungathandize kuzindikira thanzi la makina onse komanso mtundu wa mphamvu.
Mafunso Ofunsidwa Kawirikawiri (FAQ) kwa Akatswiri
Q1: Dongosolo langa limagwiritsa ntchito Wi-Fi, osati ZigBee. Kodi ndingagwiritsebe ntchito izi?
Yankho: PC321 idapangidwira chilengedwe cha ZigBee, chomwe chimapereka netiweki yokhazikika komanso yotsika ya maukonde yoyenera kugwiritsa ntchito poyang'anira zinthu monga kuteteza mphamvu kumbuyo. Kuphatikiza kumachitika kudzera pachipata chogwirizana ndi ZigBee, chomwe nthawi zambiri chimatha kutumiza deta ku nsanja yanu yamtambo.
Q2: Kodi dongosololi limalumikizana bwanji ndi inverter ya PV kuti liziwongolera?
A: Chotsekera chamagetsi chokha sichilamulira inverter mwachindunji. Chimapereka deta yofunika kwambiri nthawi yeniyeni kwa wowongolera logic (yomwe ingakhale gawo la chipata chodziyimira payokha cha nyumba kapena makina odziyimira pawokha oyendetsera mphamvu). Wowongolera uyu, akalandira chizindikiro cha "kubwerera kwa mphamvu" kuchokera ku chotsekera, amatumiza lamulo loyenera la "curtail" kapena "reduce output" ku inverter kudzera mu mawonekedwe ake othandizira (monga Modbus, HTTP API, dry contact).
Q3: Kodi kulondolako ndikokwanira kuti pakhale kulipira kovomerezeka kwa magetsi?
A: Ayi. Chipangizochi chapangidwa kuti chizigwiritsidwa ntchito poyang'anira ndi kulamulira mphamvu, osati polipira zinthu zofunika. Kulondola kwake kwakukulu (<±1.8%) n'kwabwino kwambiri pa mfundo zoyendetsera komanso kupereka deta yodalirika kwambiri yogwiritsira ntchito kwa wogwiritsa ntchito, koma chilibe ziphaso zovomerezeka za MID kapena ANSI C12.1 zofunika poyesa ndalama zovomerezeka.
Q4: Kodi njira yokhazikitsira yachizolowezi ndi iti?
A:
- Kuyika: Mangani chipangizo chachikulu pa DIN rail mu bolodi logawa.
- Kukhazikitsa CT: Yatsani makina. Ikani ma CT okhala ndi mitundu yosiyanasiyana kuzungulira mizere yayikulu yoperekera magetsi.
- Kulumikiza kwa Volti: Lumikizani chipangizocho ku voltage ya mzere.
- Kuphatikiza Netiweki: Gwirizanitsani chipangizocho ndi chipata chanu cha ZigBee kuti muphatikize deta ndikukhazikitsa njira yowongolera.
Gwirizanani ndi Katswiri mu Smart Power Metering ndi PV Solutions
Kwa ogwirizanitsa ndi ogulitsa makina, kusankha mnzanu woyenera waukadaulo ndikofunikira kwambiri monga kusankha zigawo zoyenera. Ukatswiri pa kuyeza kwanzeru komanso kumvetsetsa bwino momwe ma photovoltaic amagwiritsidwira ntchito ndizofunikira kwambiri pakuwonetsetsa kuti polojekiti ikuyenda bwino komanso kuti makinawo akhale odalirika kwa nthawi yayitali.
Owon ndi wopanga waluso kwambiri pankhani ya njira zamakono zoyezera magetsi, kuphatikizapo PG321 Power Clamp. Zipangizo zathu zimapangidwa kuti zipereke deta yolondola komanso yeniyeni yofunikira popanga njira zolimba zotetezera magetsi, kuthandiza anzathu kuthana ndi mavuto aukadaulo ndikupereka njira zamagetsi zovomerezeka komanso zogwira ntchito bwino pamsika.
Kuti mufufuze momwe njira zapadera zowunikira mphamvu za Owon zingapangire maziko a zopereka zanu za PV pa khonde, tikukupemphani kuti mulumikizane ndi gulu lathu lazogulitsa zaukadaulo kuti mudziwe zambiri komanso thandizo logwirizanitsa.
