Kuyang'anira Battery ya Substation: Kuzindikira Zolakwa Zoyambirira, Kuchita Zotetezeka, ndi Kuphatikiza Kosavuta

Malo ochepera amakono amadalira makina a batri a DC kuti agwiritse ntchito ma relay oteteza, zowononga madera, zida za SCADA, njira zoyankhulirana, ndi kuyatsa kwadzidzidzi panthawi yamagetsi. Selo limodzi lofooka likalephera, kudalirika kwa chingwe chonse cha batri kumatha kusokonezedwa.

limapereka Dongosolo loyang'anira batire la substation mawonekedwe mosalekeza mumayendedwe a batri. Poyang'anira chingwe chilichonse cha batire ndi nthawi yeniyeni, zothandizira zimatha kuzindikira zizindikiro zoyamba kuwonongeka, kuchepetsa kuwunika pamanja, ndikupewa kulephera kwamagetsi kwa DC mosayembekezereka.

Chifukwa Chake Kuyang'anira Battery ya Substation Ndikofunikira

Mabatire a substation nthawi zambiri amakhala pamalipiro oyandama kwa zaka zambiri. Panthawi imeneyi, ukalamba, dzimbiri, kugwirizana kotayirira, mavuto olipira, ndi kusintha kwa kutentha kumatha kukhala popanda zizindikiro zoonekeratu.

Kuyang'ana kwakanthawi kumangopereka chithunzithunzi cha momwe batire ilili. Poyerekeza, chowunikira cha batri chapaintaneti chimagwira ntchito 24/7 ndikuzindikira kusintha kwachilendo kusanakhudze zida zofunika.

Kuwunika pafupipafupi kumathandizira zida:

• Dziwani maselo ofooka kapena omwe akuwonongeka msanga
• Pewani chitetezo cha relay ndi kulephera kwa ma circuit breaker
• Chepetsani kuchuluka kwa ntchito yoyendera pamanja
• Kupititsa patsogolo chitetezo cha ogwira ntchito ndi zida
• Kuthandizira kukonza batire motengera momwe zinthu ziliri
• Wonjezerani kudalirika kwa dongosolo la substation DC

Zowopsa Zodziwika mu Unmonitored DC Battery Systems

Kuwonongeka kwa batri nthawi zambiri kumayamba pang'onopang'ono osati kuchitika popanda chenjezo. Dongosolo lodalirika loyang'anira batire la DC limatha kuzindikira ambiri mwamavutowa kudzera mumagetsi, kukana, kutentha, ndi zomwe zikuchitika.

Zowopsa zomwe zimafala ndi:

• Kukalamba kwa batri ndi kutaya mphamvu
• Kuwonjezeka kukana kwamkati
• Kusayenda bwino kwa ma cell voltage
• Zolumikizira zotayira kapena zowonongeka
• Kutentha kwa batri kwachilendo
• Chaja kapena zoyandama-panopa zolakwika
• Ripple current ndi kusalingana kwa zingwe

Popanda kuwunika mosalekeza, izi zitha kukhala zobisika mpaka batire ikufunika panthawi yadzidzidzi.

Ni-Cd ndi VRLA Battery Monitoring

Malo amagetsi amagetsi amagwiritsa ntchito Nickel-Cadmium (Ni-Cd), Valve-Regulated Lead-Acid (VRLA), kapena mabatire a lead-acid omwe asefukira. Chemistry iliyonse imafunikira njira yoyenera yowunikira.

Ni-Cd Battery Monitoring

Kuwunika kwa batire la Ni-Cd kuyenera kuyang'ana kwambiri mphamvu yamagetsi amtundu uliwonse, momwe amapangira, kutentha, kukalamba kokhudzana ndi ma electrolyte, komanso magwiridwe antchito a zingwe. Chifukwa kusintha kwa kukana kwamkati kungakhale kocheperako poyerekeza ndi mabatire a VRLA, ma voltage a nthawi yayitali ndi ma charger ndizofunikira kwambiri.

VRLA Battery Monitoring

Kuwunika kwa batri la VRLA nthawi zambiri kumayang'ana kwambiri mphamvu yamagetsi, kukana kwamkati, kutentha, kuyitanitsa pakali pano, komanso kuwonongeka kwa mphamvu. Kuchulukirachulukira kwamphamvu kwamkati kumatha kupereka chenjezo loyambirira la kukalamba kwa batri komanso kuchepa kwa kuthekera kosunga zosunga zobwezeretsera.

Njira yosinthira yowunikira batire yosinthika iyenera kuthandizira mabatire a Ni-Cd, VRLA, VLA, ndi lithiamu papulatifomu imodzi.

Kodi Battery ya Substation iyenera kuyeza chiyani?

Dongosolo logwira ntchito liyenera kuyang'anira ma cell onse ndi chingwe chonse cha batri. Zofunikira kwambiri ndizotsatirazi.

Ma cell Voltage

Kuwunika kosalekeza kwa ma cell voltage kumazindikira ma cell ofooka, kuchulukira, kutsika pang'ono, komanso kusalinganiza kwamagetsi. Ngakhale kupatuka pang'ono kungasonyeze vuto lomwe likukulirakulira.

Kutentha kwa Battery

Kutentha kwambiri kumathandizira kukalamba kwa batri, pomwe kutentha kosafanana kumatha kuwonetsa mpweya wabwino, zovuta zolipiritsa, kapena ma cell opanda pake. Ma alarm a nthawi yeniyeni amathandizira kupewa kuwonongeka kwa kutentha.

Kukaniza Kwamkati

Kukana kwamkati ndi chimodzi mwa zizindikiro zothandiza kwambiri za kuwonongeka kwa batri. Kuwunika kwamayendedwe kumatha kuwulula ukalamba nthawi yayitali kutayika kwa mphamvu kusanawonekere pakuyesa kutulutsa.

String Voltage ndi Current

Mpweya wamagetsi, magetsi oyandama, magetsi opangira / kutulutsa, ndi ma ripple current amapereka chidziwitso chofunikira chokhudza momwe ma charger amagwirira ntchito komanso momwe batire ilili.

Terminal ndi Connection Condition

Malo otayirira kapena ochita dzimbiri angayambitse kutsika kwa magetsi ndi kutentha komweko. Kuzindikira kusagwirizana kosagwirizana kumathandizira magulu okonza kukonza mavutowa asanakhale zoopsa zachitetezo.

Kuphatikiza ndi SCADA ndi Substation Automation

Zothandizira nthawi zambiri zimafunikira deta ya batri kuti ipezeke kudzera mu SCADA, EMS, DCS, kapena nsanja zoyang'anira maukonde. Dongosolo lamakono loyang'anira mabatire pazothandizira liyenera kuthandizira njira zolumikizirana zamafakitale.

Zosankha zophatikiza zodziwika bwino ndi izi:

• Modbus RTU
• Modbus TCP/IP
• Chithunzi cha SNMP
• IEC 61850
• REST API

Kuwunika kwa batri la IEC 61850 ndikofunikira kwambiri pamagawo a digito chifukwa kumathandizira kulumikizana ndi zida zanzeru zamagetsi ndi makina opangira makina.

Mfundo zazikuluzikulu za Kutumiza Kwadongosolo

Musanasankhe makina owunikira ma batire a kagawo kakang'ono, mainjiniya akuyenera kutsimikizira izi:

• Battery chemistry ndi nominal cell voltage
• Chiwerengero cha ma cell ndi zingwe za batri
• Charger ndi DC dongosolo kasinthidwe
• Zofunika kuwunika magawo
• RS485, Ethernet, CHIKWANGWANI, kapena 4G kuyankhulana kupezeka
• SCADA, EMS, DCS, kapena IEC 61850 zofunika kuphatikiza
• Malo oyika m'nyumba kapena kunja
• Imelo, SMS, ndi alamu yapulatifomu

Zowunikira zowunikira ziyenera kuyikidwa popanda kusokoneza magwiridwe antchito a batri nthawi zonse ngati kuli kotheka. Njira zoyendetsera chingwe, kutsekereza, kuyanjana kwamagetsi, komanso njira zotetezera magetsi ziyeneranso kuganiziridwa.

Ma Alamu Anzeru ndi Kukonzekera Kwamtsogolo

Dongosolo la akatswiri liyenera kupereka zambiri kuposa zomwe zidapangidwa. Ma alarm amitundu ingapo, zomwe zikuchitika m'mbiri, komanso malipoti odzipangira okha amathandiza mainjiniya kumvetsetsa kuti ndi selo liti lomwe silili bwino, likuwonongeka mwachangu bwanji, komanso nthawi yomwe akufunika kukonza.

Zothandiza zikuphatikizapo:

• Ma alarm anthawi yeniyeni ndi zingwe
• Kusanthula kwamagetsi, kutentha, ndi kukana
• Chizindikiritso cha maselo ofooka
• Chidule cha thanzi la batri
• Mbiri ya ma alarm ndi malipoti okonza
• Kuwongolera kwamawebusayiti ambiri

Izi zimathandizira kuti zida zogwiritsira ntchito zisunthike kuchoka m'malo omwe zidakonzedweratu kupita ku kukonza motengera momwe zilili, kuchepetsa kuyendera malo osafunikira komanso ndalama zosinthira mabatire.

DFUN Substation Battery Monitoring Solution

DFUN imapereka yankho lathunthu loyang'anira mabatire am'malo amagetsi, ma netiweki otumizira ndi kugawa, malo opangira magetsi, zida zamafakitale, ndi magetsi ongowonjezedwanso.

Mafunso Ofunsidwa Kawirikawiri

Kodi makina owunikira batire angayikidwe popanda kuzimitsa kagawo kakang'ono?

M'mapulojekiti ambiri, njira yowunikira ikhoza kukhazikitsidwa ndikuchepetsa kusokoneza ntchito zomwe zilipo kale. Mapulani oyika akuyenera kutsatira njira zotetezera magetsi pa malo.

Kodi makina amodzi angayang'anire mabatire onse a Ni-Cd ndi VRLA?

Inde. Pulatifomu yaukadaulo yowunikira batire imatha kuthandizira ma chemistries angapo, kuphatikiza Ni-Cd, VRLA, VLA, ndi mabatire a lithiamu.

Kodi kuyang'anira batire pa intaneti kumalowetsa kuyesa mphamvu?

Ayi. Kuyang'anira pa intaneti kumapereka chenjezo losalekeza, pomwe kuyezetsa mphamvu kwanthawi ndi nthawi kumatsimikizira kuchuluka kwa zosunga zobwezeretsera ndi nthawi yothamanga. Kugwiritsa ntchito zonsezi kumapereka chidziwitso chokwanira chaumoyo wa batri.

Kodi dongosololi limachepetsa bwanji ma alarm abodza?

Mipata yosinthika, kuchedwa kwa ma alarm, zidziwitso zamagawo angapo, ndi kusanthula zochitika zimathandizira kusiyanitsa kuwonongeka kwenikweni ndi kusinthasintha kwakanthawi.

Pemphani Pempho Laling'ono Loyang'anira Battery

Kuti mupereke yankho loyenera, chonde perekani mtundu wa batri, mphamvu yamagetsi, chiwerengero cha maselo ndi zingwe, njira yolankhulirana, SCADA yomwe ilipo kapena nsanja yodzipangira, zofunikira za alamu, ndi malo oyikapo.

Lumikizanani ndi DFUN kuti mukambirane za projekiti yanu ndikulandila dongosolo loyang'anira batire laling'ono.
