Daga Yadda da Hanyar da Kyau da Kawo Tushen Farkon Tsakiyar Kasa?

Yadda na Yanzu ta Daidaito Masu Mafi Inganci a Karkashin Fadada Tsakiyar Zane

Tana da yawan tsarin daidaito masu mafi inganci a karkashin fadada tsakiyar zane a cikin hanyoyi da ba suka samun damar (kamar hanyoyin looped da open-loop), yanayin damar da take taka (kamar ungrounded, arc-suppression coil grounded, da low-resistance grounded systems), yaɗuwar shekaru na kashi da kabel ko sabbin shiga-kabel wiring, da kuma abubuwan fadada mai gaskiya (kamar fadada rayukansu, tree flashovers, wire breakages, da personal electric shocks).

Kategoriyoyi na Fadada Tsakiyar Zane

Abubuwan fadada a cikin grid na nishadance sun haɗa da metallic grounding, lightning discharge grounding, tree branch grounding, resistance grounding, da poor insulation grounding. Sun haɗa da sasheƙu na arc grounding, kamar short-gap discharge arcs, long-gap discharge arcs, da intermittent arcs. Wasu alamomin fadada da ke faruwa daga cikin abubuwan fadada sun ce ta ɗauke da tsari da yawa.

Aiki na Teknologi na Iyakokin Fadada Tsakiyar Zane

• Teknologi na arc-suppression compensation da iyakokin personal electric shock

• Iyakokin overvoltage

• Zabbar hanyar da mutanen da ke fadada, zaɓi lokacin da ke fadada, da kuma ƙarfafar lokacin da ke fadada

• Relay protection: Iyakokin fadada

• Feeder automation: Iyakokin fadada da jirgin bayanin kashi

Matsalolin Fadada Tsakiyar Zane

• Yanayin damar da take taka

• Yanayin damar: Tsawon damar

• Yanayin hanyoyi: Overhead lines, cable lines, da hybrid overhead-cable lines

• Yanayin lokaci da lokacin da ke fadada

Gaskiya na Alamomin Fadada Tsakiyar Zane

• Karamin kudaden damar da ya fi ƙeƙa; kudaden damar na resonant grounding ya fi ƙeƙa da 10 A.

• Kudaden damar na arc-suppression coil ya yi amfani da zero-sequence current na hanyar da ke fadada ɗaya ɗaya da yawa da hanyoyi da ba suka fadada ba, a kan yadda ake gano.

• Fadada da ta yi damar tsakanin lokaci; kusan fadada sun haɗa da fadada da ta yi damar tsakanin lokaci.

• Kasa mai yawa da fadada da kudaden damar mai yawa (kudaden damar da yake da 1,000 ohms), wanda ya shafi kusan 5%. Hata a kan low-resistance grounding, ita ce mai zurfi a ƙirƙira fadada da kudaden damar mai yawa.

• Sauran dalilai na fadada electric shock a cikin distribution network: ① Annabi ta gama da karamin kudaden damar ko ta gama da karamin kudaden damar da take aiki; ② Kudaden damar ta sauke zuwa ƙasa. Duka electric shock da kudaden damar ta sauke zuwa ƙasa sun haɗa da kudaden damar mai yawa. Saboda haka, iyakokin electric shock a cikin distribution networks tana iya kasance munaɗar iyakokin fadada da kudaden damar mai yawa.

Hanyoyin Ƙarfafar Lokacin da Ke Fadada Tsakiyar Zane

Yana da hanyoyi uku, da kowane uku na 20 hanyoyi ƙanan, don ƙarfafa lokacin da ke fadada tsakiyar zane:

Artificial intelligence (AI) tana cikin teknologiyoyi masu zamani. Tana yi amfani da tushen al'umma a kan mutanen, hayawayen, ko kuma mazauna, don bincike alamomin da suke faru, kuma tana hallar masu matsaloli a nan. Idan an yi amfani da computer computing, zai iya sauya karfin aiki, kuma tana iya hallar cikin sistema masu gaskiya kamar grid na nishadance.

• Expert Database: Tana yi amfani da database don taimaka da ilimi da tajammi.

• Artificial Neural Network: Tana yi amfani da tushen neuron na mutanen don hallar masu matsaloli, kuma tana iya hallar cikin sistema masu gaskiya.

• Ant Colony Optimization: Tana yi amfani da tushen hayawayen ant don ƙarfafa masu matsaloli, kamar traveling salesman problem.

• Genetic Algorithm: Tana yi amfani da tushen darasi na hayawayen don samun ƙarfin da ya fi ƙeƙa ko kuma ƙarfin da ya fi ƙeƙa.

• Petri Net: Tana yi amfani da tushen takamardukan komponanta a cikin sistema, kuma tana taimaka a taka tushen da suke faruwa a kan lokutan da suka faruwa.

• Rough Set Theory: Tana yi amfani da cikakken bayanai don taimaka a taka tushen da suke faruwa a cikin sistema.

Daga cikin hanyoyin AI, akwai kowane da ya fi ƙeƙa a cikin littattafan, amma akwai kowane da ya yi amfani a kan zamanin yanzu. Amma, AI tana nuna muhimmancinsa a cikin zamanin yanzu.
