Uma Uhlelo Lokuphathwa Kwamandla luhluleka ukuletha ulwazi oluthembekile, inkinga akuyona njalo isofthiwe.
Emaphrojekthini amaningi, inkinga yangempela iqala ezingeni lemitha.
Uma imitha yamandla ingakwazi ukunikeza ukuxhumana okuzinzile, idatha yesikhathi sangempela enembile, noma imingcele kagesi efanele, ipulatifomu ye-EMS izobonisa kuphela ulwazi olungaphelele noma olubambezelekile. Kwezakhiwo zezentengiselwano, izikhungo zezimboni, izinhlelo ze-PV zelanga, kanye namaphrojekthi okugcina amandla, ukukhetha okulungileimitha yamandla ye-modbusngakho-ke kuyisinqumo esibalulekile sobunjiniyela.
Imitha enhle akufanele nje ilinganise ukusetshenziswa kwamandla kuphela. Kufanele futhi isekele ukufakwa okungokoqobo, ixhumane ngokuthembekile nabalawuli noma amaseva, futhi inikeze idatha edingekayo yokuhlaziywa kwamandla, ukuzenzekela, ukubika, kanye nokwenza ngcono uhlelo.
Kungani iModbus Isabalulekile Kumaphrojekthi E-EMS
I-Modbus isasetshenziswa kabanzi ekuphathweni kwamandla ngoba ilula, ivulekile, futhi isekelwa amapulatifomu amaningi e-EMS, BMS, PLC, kanye ne-SCADA.
Kwabahlanganisi bezinhlelo, lokhu kubalulekile ngoba idatha yamandla ivame ukudingwa ukuqoqwa kumadivayisi ahlukene kuwo wonke amakamelo kagesi, izindawo zokukhiqiza, izinhlelo zelanga, kanye nemishini yemishini. Imitha esekela iModbus ingafakwa engqalasizinda ekhona ngaphandle kokuphoqa iphrojekthi ukuthi incike epulatifomu eyodwa yamafu evaliwe.
Kumaphrojekthi amaningi e-EMS, izinketho ezimbili ze-Modbus zivame ukucatshangelwa:
I-Modbus RTU ngaphezulu kwe-RS485ivame ukusetshenziselwa ukuxhumana kwezimboni okunezintambo. Ifaneleka ekuxhumaneni kwendawo okuzinzile, ukuxhumanisa izintambo ibanga elide, kanye nokuhlola okusekelwe kumlawuli.
I-Modbus TCPisetshenziswa ngamanethiwekhi e-IP. Ngokuvamile kulula ukuxhumana namaseva, amasango, amadeshibhodi, kanye namapulatifomu wamandla asekelwe kunethiwekhi yendawo.
Kumaphrojekthi amaningi esimanje, ikhambi elingcono kakhulu akusikho ukukhetha elilodwa kuphela. Imitha eguquguqukayo esekela i-Modbus TCP kanye ne-Modbus RTU inikeza abahlanganisi bezinhlelo izinketho eziningi ngesikhathi sokufakwa.
Hlola Uhlelo Lukagesi Kuqala
Ngaphambi kokuqhathanisa izici zesofthiwe, qinisekisa indawo kagesi.
Iphrojekthi ye-EMS ingabandakanya:
- Izinhlelo zesigaba esisodwa
- Izinhlelo zesigaba esihlukanisiwe
- Izinhlelo zezintambo ezine zesigaba ezintathu
- Izinhlelo ze-PV zelanga
- Izinhlelo zokugcina amandla
- Imithwalo exubile yezentengiselwano noma yezimboni
Uma imitha isekela ukucushwa kukagesi okukodwa kuphela, ingase ikhawulele ukuthunyelwa kwesikhathi esizayo. Kwabasabalalisi, ozakwethu be-OEM, kanye nabahlanganisi bezinhlelo, ukusebenzisa ipulatifomu yemitha eyodwa kuzo zonke izinhlobo zephrojekthi kunganciphisa ubunzima bempahla futhi kwenze ukuhlela ukufakwa kube lula.
Yingakho imitha ye-Modbus enezinhlelo eziningi ivame ukuba wusizo kakhulu kunemitha eyenzelwe indawo eyodwa kuphela yokuxhuma izintambo.
Ukufakwa Kwezikhonkwane Ze-CT Kubalulekile Emisebenzini Yokuvuselela
Ezakhiweni eziningi ezikhona, ukuvala ugesi noma ukufaka kabusha amaphaneli okusabalalisa kunzima.
Yilapho i-imitha yamandla e-ct clampiba yigugu.
Esikhundleni sokubeka ugesi ogcwele ngqo ngemitha, amamitha e-CT clamp alinganisa ugesi ngokusebenzisa ama-transformer angaphandle. Le ndlela iwusizo kakhulu kumaphrojekthi okuqapha amandla okuvuselela ngoba inganciphisa ukuphazamiseka kokufakwa futhi isekele izinhlelo zokusebenza zamandla aphezulu.
Ezakhiweni zezentengiselwano, emafektri, ezikoleni, emahhotela, kanye namaphrojekthi okulungisa kabusha amandla elanga, ukulinganisa okusekelwe ku-CT kuvame ukuba usizo kakhulu kunokulinganisa okuxhunywe ngqo.
Uma ukhetha imitha ye-CT clamp, hlola:
- Izilinganiso zamanje ze-CT ezisekelwayo
- Inani lezinto ezifakwayo ze-CT
- Ububanzi bokunemba
- Ubude bekhebula
- Indlela yokufaka
- Ukuthi imitha iyakusekela yini ukuqapha ukungenisa/ukuthumela ngaphandle
Isibonelo, iphrojekthi yezigaba ezintathu ngokuvamile idinga okokufaka kwe-CT okufika kathathu. Amaphrojekthi okugcina amandla elanga nawo angadinga nokuqapha izinhlangothi zombili ukuze kuqondwe kokubili ukusetshenziswa kanye nokukhiqizwa kwawo.
Kungani i-RS485 isasebenza
Nakuba i-Ethernet ne-WiFi zivame kakhulu namuhla, i-RS485 isabalulekile ezinhlelweni zokuphathwa kwezimboni kanye namandla.
Okuthembekileimitha yamandla ye-rs485kuyasiza lapho iphrojekthi idinga ukuxhumana okunezintambo, ukuvota kwendawo okuzinzile, noma ukuhlanganiswa nabalawuli kanye namasango ezimboni.
I-RS485 ifaneleka kakhulu ku:
- Ukuhlanganiswa kwe-PLC
- Ukuvota kwabalawuli bendawo
- Amaphaneli ezenzakalelayo zezimboni
- Ukuxhumana kwe-inverter yelanga
- Ukuxhumana ngentambo okude
- Amasayithi lapho ukuxhumana okungenantambo kungathandwa khona
Kumaphrojekthi e-EMS, i-RS485 ayiphelelwe yisikhathi. Ngokuvamile iyindlela ezinzile kakhulu futhi ebikezelwayo.
Ungabheki i-kWh kuphela
Idatha eyisisekelo ye-kWh iwusizo, kodwa amapulatifomu e-EMS anamuhla avame ukudinga okwengeziwe.
Imitha yamandla enamandla yeModbus kufanele ihlinzeke:
- I-voltage
- Okwamanje
- Imvamisa
- Isici samandla
- Amandla asebenzayo
- Amandla okusabela
- Amandla abonakalayo
- Idatha yamandla yokungenisa/ukuthumela ngaphandle
Amandla asebenzayo kanye namandla abonakalayo awusizo kakhulu ekuhlaziyweni kwamandla ezentengiselwano kanye nezimboni. Asiza onjiniyela ukuqonda hhayi nje kuphela ukuthi kusetshenziswa ugesi ongakanani, kodwa nokuthi imithwalo kagesi isebenza kahle kangakanani.
Ngezinhlelo zokusebenza ze-solar PV kanye nesitoreji samandla, ukuqapha okuqondiswayo nakho kubalulekile. I-EMS noma ipulatifomu ye-inverter idinga ukwazi ukuthi ugesi ungeniswa kusuka kugridi noma uthunyelwa kusuka endaweni.
Cabanga nge-EMS, i-BMS, i-SCADA kanye nokuhlanganiswa kwamafu okuyimfihlo
Imitha esetshenziswa kumaphrojekthi e-EMS akufanele yahlulelwe kuphela ngohlelo lwayo lokusebenza lweselula.
Kumaphrojekthi e-B2B, ukuguquguquka kokuhlanganiswa kubaluleke kakhulu.
Kuye ngephrojekthi, imitha kungadingeka ixhumane nalokhu:
- Amapulatifomu e-EMS
- Amapulatifomu e-BMS
- Izinhlelo ze-SCADA
- Izilawuli ze-PLC
- Ama-inverter elanga
- Izilawuli zokugcina amandla
- Amaseva efu ayimfihlo
- Amadeshibhodi endawo
Yingakho izinqubo zokuxhumana ezifana ne-Modbus RTU, i-Modbus TCP, i-MQTT, kanye ne-HTTP zingaba usizo. Zivumela abahlanganisi bezinhlelo ukuthi banqume ukuthi idatha kufanele ifundwe endaweni, ithunyelwe kuseva yangasese, noma ixhunywe kwipulatifomu enkulu yokuphathwa kwamandla.
Lapho i-PC4713 ifanela khona
Kumaphrojekthi adinga ukuxhumana kwe-Modbus, ukuxhumana kwe-RS485, kanye nokuqapha okusekelwe ku-CT clamp, imikhiqizo efana ne-I-OWON PC4713-W-485zenzelwe izinhlelo zokusebenza zokuqapha amandla ezimboni ze-EMS, BMS, solar PV kanye nezimboni.
I-PC4713-W-485 isekela ukuxhumana kwe-WiFi kanye ne-RS485. Ukuxhumana kwayo kwe-WiFi kusekela i-HTTP, i-MQTT, kanye ne-Modbus TCP, kuyilapho i-RS485 port isekela i-Modbus RTU. Iphinde isekele ukuqapha kwe-voltage, i-current, i-power factor, imvamisa, amandla asebenzayo, amandla asabelayo, amandla abonakalayo, kanye nokugeleza kwamandla okuya ohlangothini ngalunye.
Lokhu kwenza kube kuhle kumaphrojekthi lapho idatha yamandla kufanele iqoqwe yipulatifomu ye-EMS, iseva yendawo, isilawuli se-inverter, noma uhlelo lokuzenzakalela kwezimboni.
Kwabahlanganisi bezinhlelo abafuna i-scalableimitha yamandla ye-modbus, ipulatifomu esekelwe ku-CT enokusekelwa kwe-RS485 kanye ne-Modbus TCP inganciphisa ubungozi bokuhlanganiswa futhi ithuthukise ukuguquguquka kokusetshenziswa kwesikhathi eside.
Imicabango Yokugcina
Ukukhetha imitha yamandla ye-Modbus yokuhlanganiswa kwe-EMS akukhona nje ukuthola idivayisi esekela i-Modbus.
Umbuzo ongcono uthi:
Ingabe imitha inganikeza idatha enembile, ukuxhumana okuthembekile, ukufakwa okuguquguqukayo, kanye nemingcele kagesi eyanele yephrojekthi?
Ezakhiweni zezentengiselwano, izinhlelo ze-solar PV, izikhungo zezimboni, kanye namaphrojekthi okugcina amandla, ukukhetha okungcono kakhulu ngokuvamile imitha esekela i-Modbus TCP, i-Modbus RTU, ukuxhumana kwe-RS485, ukulinganiswa kwe-CT clamp, kanye nokuqapha amandla okubheka izinhlangothi zombili.
Leyo nhlanganisela inikeza abahlanganisi be-EMS ukuguquguquka abakudingayo ukwakha izinhlelo zokuqapha amandla ezithembekile, ezikwazi ukulinganiswa, nezilungele ikusasa.
