Pamene Energy Management System ikulephera kupereka chidziwitso chodalirika, vuto silimakhala nthawi zonse pa mapulogalamu.
Mu mapulojekiti ambiri, vuto lenileni limayambira pa mulingo wa mita.
Ngati choyezera mphamvu sichingathe kupereka kulumikizana kokhazikika, deta yolondola ya nthawi yeniyeni, kapena magawo oyenera amagetsi, nsanja ya EMS idzangowonetsa chidziwitso chosakwanira kapena chochedwa. Pa nyumba zamalonda, mafakitale, makina a dzuwa a PV, ndi mapulojekiti osungira mphamvu, kusankha koyeneramita yamagetsi ya modbusChifukwa chake ndi chisankho chofunikira kwambiri chaukadaulo.
Chida chabwino sichiyenera kungoyesa momwe mphamvu imagwiritsidwira ntchito. Chiyeneranso kuthandizira kukhazikitsa koyenera, kulankhulana modalirika ndi owongolera kapena ma seva, ndikupereka deta yofunikira pakusanthula mphamvu, kudzipangira zokha, kupereka malipoti, ndi kukonza makina.
Chifukwa Chake Modbus Ikufunikabe mu Mapulojekiti a EMS
Modbus ikugwiritsidwabe ntchito kwambiri pakuwongolera mphamvu chifukwa ndi yosavuta, yotseguka, komanso yothandizidwa ndi nsanja zambiri za EMS, BMS, PLC, ndi SCADA.
Kwa ogwirizanitsa makina, izi ndizofunikira chifukwa nthawi zambiri deta ya mphamvu imafunika kusonkhanitsidwa kuchokera ku zipangizo zosiyanasiyana m'zipinda zamagetsi, malo opangira zinthu, makina a dzuwa, ndi zida zamakanika. Chida choyezera chomwe chimathandizira Modbus chingaphatikizidwe mu zomangamanga zomwe zilipo popanda kukakamiza pulojekitiyi kudalira nsanja imodzi yotsekedwa ya mitambo.
Mu mapulojekiti ambiri a EMS, njira ziwiri za Modbus nthawi zambiri zimaganiziridwa:
Modbus RTU pa RS485nthawi zambiri imagwiritsidwa ntchito polumikizirana ndi mafakitale pogwiritsa ntchito waya. Ndi yoyenera kugwiritsa ntchito maukonde okhazikika am'deralo, mawaya akutali, komanso kufufuza pogwiritsa ntchito olamulira.
Modbus TCPimagwiritsidwa ntchito pa maukonde a IP. Nthawi zambiri zimakhala zosavuta kulumikizana ndi ma seva, zipata, ma dashboard, ndi nsanja zamagetsi zapaintaneti zakomweko.
Pa mapulojekiti ambiri amakono, yankho labwino kwambiri si kusankha imodzi yokha. Chida chosinthasintha chomwe chimathandizira Modbus TCP ndi Modbus RTU chimapatsa ophatikiza dongosolo zosankha zambiri panthawi yogwiritsa ntchito.
Yang'anani Kachitidwe ka Magetsi Choyamba
Musanayerekezere zinthu za pulogalamu, tsimikizirani malo amagetsi.
Pulojekiti ya EMS ingaphatikizepo:
- Machitidwe a gawo limodzi
- Machitidwe ogawanika
- Makina a waya anayi a magawo atatu
- Makina a PV a dzuwa
- Machitidwe osungira mphamvu
- Mitundu yosiyanasiyana yamalonda kapena mafakitale
Ngati mita ikuthandizira kasinthidwe kamodzi kokha ka magetsi, ikhoza kuchepetsa kutumizidwa kwa magetsi mtsogolo. Kwa ogulitsa, ogwirizana ndi OEM, ndi ophatikiza makina, kugwiritsa ntchito nsanja imodzi ya mita m'mitundu yosiyanasiyana ya mapulojekiti kungachepetse zovuta zomwe zili m'sitolo ndikupangitsa kukonzekera kukhazikitsa kukhala kosavuta.
Ichi ndichifukwa chake mita ya Modbus yokhala ndi machitidwe ambiri nthawi zambiri imakhala yothandiza kwambiri kuposa mita yopangidwira malo amodzi okha olumikizira mawaya okhazikika.
Kukhazikitsa Chida cha CT N'kofunika Kwambiri pa Ntchito Zokonzanso Zinthu
M'nyumba zambiri zomwe zilipo, kuzimitsa magetsi kapena kuyikanso mawaya ogawa magetsi n'kovuta.
Apa ndi pamenemita ya mphamvu ya ct clampimakhala yamtengo wapatali.
M'malo moyika mphamvu yonse yonyamula katundu mwachindunji kudzera mu mita, ma CT clamp mita amayesa mphamvu kudzera mu ma transformer akunja. Njira imeneyi ndi yothandiza kwambiri pamapulojekiti owunikira mphamvu chifukwa imatha kuchepetsa kusokonezeka kwa kukhazikitsa ndikuthandizira kugwiritsa ntchito mphamvu zambiri.
Pa nyumba zamalonda, mafakitale, masukulu, mahotela, ndi mapulojekiti okonzanso magetsi pogwiritsa ntchito mphamvu ya dzuwa, kuyeza magetsi pogwiritsa ntchito CT nthawi zambiri kumakhala kothandiza kuposa kuyeza magetsi pogwiritsa ntchito njira yolumikizirana mwachindunji.
Posankha mita yoyezera CT, onani:
- Ma CT current ratings othandizidwa
- Chiwerengero cha zinthu zomwe zimalowa mu CT
- Kulondola kwamtundu
- Kutalika kwa chingwe
- Njira yokhazikitsira
- Kaya mitayo imathandizira kuyang'anira kutumiza/kutumiza kunja
Mwachitsanzo, pulojekiti ya magawo atatu nthawi zambiri imafuna ma CT inputs atatu. Mapulojekiti osungira mphamvu ndi dzuwa angafunikenso kuyang'aniridwa mbali zonse ziwiri kuti amvetsetse momwe amagwiritsidwira ntchito komanso momwe amapangira.
Chifukwa Chake RS485 Ikadali Yothandiza
Ngakhale kuti Ethernet ndi WiFi ndizofala masiku ano, RS485 ikadali yofunika kwambiri m'mafakitale ndi machitidwe oyendetsera mphamvu.
Wodalirikamita ya mphamvu ya rs485Ndi yothandiza pamene polojekitiyi ikufuna kulumikizana ndi waya, kufufuza kokhazikika kwa anthu am'deralo, kapena kuphatikiza ndi owongolera ndi zipata zamafakitale.
RS485 ndi yoyenera kwambiri pa:
- Kuphatikiza kwa PLC
- Kuvota kwa olamulira am'deralo
- Mapanelo odzichitira okha a mafakitale
- Kulankhulana kwa inverter ya dzuwa
- Kulankhulana kwa waya patali
- Masamba omwe kulankhulana opanda zingwe sikukondedwa
Pa mapulojekiti a EMS, RS485 si yakale. Nthawi zambiri ndiyo njira yokhazikika komanso yodziwikiratu.
Musayang'ane kWh yokha
Deta yoyambira ya kWh ndi yothandiza, koma nsanja zamakono za EMS nthawi zambiri zimafuna zambiri.
Chiyeso champhamvu cha mphamvu cha Modbus chiyenera kupereka:
- Voteji
- Zamakono
- Kuchuluka kwa nthawi
- Mphamvu yamagetsi
- Mphamvu yogwira ntchito
- Mphamvu yogwira ntchito
- Mphamvu yooneka
- Deta ya mphamvu yotumiza/kutumiza kunja
Mphamvu yogwira ntchito komanso mphamvu yooneka bwino ndi yothandiza kwambiri pakuwunika mphamvu zamabizinesi ndi mafakitale. Zimathandiza mainjiniya kumvetsetsa osati kuchuluka kwa magetsi omwe akugwiritsidwa ntchito, komanso momwe katundu wamagetsi amagwirira ntchito bwino.
Pa ntchito zosungira mphamvu ya dzuwa ndi magetsi, kuyang'anira mbali zonse ziwiri ndikofunikira. EMS kapena nsanja ya inverter iyenera kudziwa ngati magetsi akutumizidwa kuchokera ku gridi kapena akutumizidwa kuchokera pamalopo.
Ganizirani za EMS, BMS, SCADA ndi Private Cloud Integration
Chida choyezera chomwe chimagwiritsidwa ntchito mu mapulojekiti a EMS sichiyenera kuweruzidwa ndi pulogalamu yake yam'manja yokha.
Pa mapulojekiti a B2B, kusinthasintha kophatikizana ndikofunikira kwambiri.
Kutengera ndi polojekitiyi, mita ingafunike kulankhulana ndi:
- Mapulatifomu a EMS
- Mapulatifomu a BMS
- Machitidwe a SCADA
- Olamulira a PLC
- Ma inverter a dzuwa
- Oyang'anira kusungira mphamvu
- Ma seva achinsinsi amtambo
- Ma dashboard am'deralo
Ichi ndichifukwa chake ma protocol olumikizirana monga Modbus RTU, Modbus TCP, MQTT, ndi HTTP angakhale othandiza. Amalola ophatikiza dongosolo kusankha ngati deta iyenera kuwerengedwa kwanuko, kutumizidwa ku seva yachinsinsi, kapena kulumikizidwa ku nsanja yayikulu yoyang'anira mphamvu.
Kumene PC4713 Ikugwirizana
Pa mapulojekiti omwe amafunikira kulumikizana kwa Modbus, kulumikizana kwa RS485, ndi kuwunika kozikidwa pa CT clamp, zinthu mongaOWON PC4713-W-485Zapangidwira EMS, BMS, solar PV, ndi ntchito zowunikira mphamvu zamafakitale.
PC4713-W-485 imathandizira kulumikizana kwa WiFi ndi RS485. Kulumikizana kwake kwa WiFi kumathandiza HTTP, MQTT, ndi Modbus TCP, pomwe doko la RS485 limathandizira Modbus RTU. Imathandizanso kuyang'anira nthawi yeniyeni ya voltage, current, power factor, frequency, active power, reactive power, visual power, ndi bidirectional energy flow.
Izi zimapangitsa kuti ikhale yoyenera mapulojekiti omwe deta ya mphamvu iyenera kusonkhanitsidwa ndi nsanja ya EMS, seva yakomweko, chowongolera cha inverter, kapena makina odziyimira pawokha a mafakitale.
Kwa ophatikiza dongosolo omwe akufuna njira yowonjezeramita yamagetsi ya modbus, nsanja yochokera ku CT yokhala ndi chithandizo cha RS485 ndi Modbus TCP ingachepetse chiopsezo chophatikizana ndikuwonjezera kusinthasintha kwa kuyika kwa nthawi yayitali.
Maganizo Omaliza
Kusankha chipangizo choyezera mphamvu cha Modbus kuti chigwirizane ndi EMS sikutanthauza kungopeza chipangizo chomwe chimagwira ntchito ndi Modbus.
Funso labwino ndi lakuti:
Kodi mitayi ingapereke deta yolondola, kulankhulana kodalirika, kukhazikitsa kosinthasintha, ndi magawo okwanira amagetsi a polojekitiyi?
Pa nyumba zamalonda, makina a PV a dzuwa, malo opangira mafakitale, ndi mapulojekiti osungira mphamvu, chisankho chabwino nthawi zambiri chimakhala mita yomwe imathandizira Modbus TCP, Modbus RTU, kulumikizana kwa RS485, kuyeza CT clamp, ndi kuyang'anira mphamvu mbali zonse ziwiri.
Kuphatikiza kumeneko kumapatsa ophatikiza a EMS kusinthasintha komwe amafunikira kuti apange njira zowunikira mphamvu zodalirika, zokulirapo, komanso zokonzeka mtsogolo.
