Ina magana ne game da tanadin ƙarfin batir. Jami'armu ta Jiaotong ta kasance tana yin ajiyar makamashi, daga tsarin wutar lantarki da motocin lantarki zuwa jigilar layin dogo. A yau muna magana ne game da wasu abubuwan da muke aiwatarwa a aikace-aikacen tsarin wutar lantarki.

Babban mahimman umarninmu na bincike: ɗayan shine micro-grid kuma ɗayan shine aikace-aikacen baturi. A aikace-aikacen baturi, motocin farko na lantarki da muka yi amfani da ajiyar kuzari a cikin tsarin wutar lantarki.

Dangane da batun mafi mahimmancin tanadin ƙarfin batir, batun farko shine aminci; na biyu shine tsawon rai, sannan kuma babban inganci.

Don tsarin adana makamashi, abu na farko da za a yi la’akari da shi shine aminci, sannan ingantacce. Yarda da inganci, ragin masu canzawa, da rayuwa, da kuma amfani da makamashi bayan faduwa baturin, bazai zama matsala mai rikitarwa ba a lamura da yawa.

Muna fatan cewa ta hanyar abubuwa da yawa, zamu iya magance matsalar rayuwa mai lafiya da ingantaccen aiki. Ana yin amfani da ingantaccen tsarin ajiya da tsarin tantance katin don matsayin batir a cikin motocin lantarki da tsarin sufuri na jama'a.

A halin yanzu, yin amfani da tsarin adana makamashi, masu kula da hanu da kwalaye rarrabuwar kawuna da kowa ke amfani da shi, inganta tattalin arziƙi da kwanciyar hankali na tsarin, haɓaka ƙimar mahimmancin masu haɗin tsarin, kuma suna iya zama abokantaka mai amfani da gajimare na ƙarshen zamani dandamali

Wannan tsarin tattara karfin kuzari ne. Wannan tsari mai zurfi an bayyana shi sosai a safiyar yau, kuma zamu iya cimma ingantaccen tsari na lokaci mai tsawo na tsirrai masu sarrafa wutar lantarki da microgrids ta hanyar sarrafawa da yawa.

Yanzu an sanya shi cikin madaidaicin ma'aikatar rarraba wutar lantarki mai ma'ana. Wannan shine asalin fasalin gidan majalisar rarraba wutar lantarki. Ya ƙunshi ayyuka daban-daban, kamar caji da cajin ayyuka, kariyar atomatik, da ayyukan mai amfani. Wannan daidaitaccen kayan aiki ne.

Mai kula da kumburi yana aiwatar da mahimman kayan aikin sarrafa wutar lantarki na gida, babban aikin tattara bayanai, saka idanu, ajiya, dabarun gudanar da aiwatarwa da loda. Akwai matsala a nan wanda ke buƙatar bincike mai zurfi da zurfi a kan ƙimar samammen bayanai da lokacin samin bayanan lokacin da aka ɗora bayanai. Ta wannan hanyar, ana aiwatar da nazarin bayanan batir a bangon batirin, kuma kulawar batirin ya zama abin kulawa. Yi wani aiki, a ƙarshe, yaya yawan samfuran yake, ko yaya ɗinbin ajiya yake, don bayyana cikakken halin da wannan batirin yake ciki.

Idan na tuka motar lantarki, zaku ga cewa motocin lantarki da yawa suna cikin yanayin sau da yawa yana canzawa da tsalle-tsalle. A zahiri, tanadin makamashi yana fuskantar matsala guda a cikin aikace-aikacen ajiya na makamashi. Muna fatan warware shi ta hanyar bayanai. Muna da samfurin samfurin BMS wanda ya dace.

Bari inyi magana game da tanadin makamashi mai sassauci. Kowa ya ce zan iya yin shi sau 6,000, kuma ana iya amfani da shi sau dubu a cikin mota. Yana da wuya a faɗi. Kuna iya taimaka masa azaman tsarin adana makamashi, kuna da'awar sau 5,000. Nawa ne amfanin amfani, saboda batirin da kanta yana da babbar matsala, raguwar batirin ba shi da matsala yayin aiwatar da koma bayan tattalin arziki, kowane batir yana raguwa daban, kuma bambanci tsakanin raka'oin guda ɗaya yana ƙara zama daidai da rashin daidaituwa na mai samarwa. Rashin batirin kuma daban. Wane irin ƙarfi ne wannan rukunin batirin zai yi amfani da kuzarin kuma yana samuwa? Wannan matsala ce da ke buƙatar bincike mai zurfi. Misali, lokacin da motocin lantarki ke amfani da su a halin yanzu, ana amfani dasu daga 10 zuwa 90%, kuma koma bayan tattalin arziki na iya amfani da kashi 60% zuwa 70% zuwa wani yanayi, wanda hakan babban kalubale ne ga ajiyar makamashi.

Shin za mu iya amfani da rukunin masu bin doka ta lalace don sasantawa, yaya girman zaɓin da ya dace don samun kyakkyawan aiki da ingantaccen aiki, muna fatan haɗuwa da shi bisa ga dokar lalacewar baturi, reshe 20 kamar yadda kumburi ya ke ya fi dacewa ko 40 sun fi dacewa, wanda ke sanya daidaito tsakanin inganci da lantarki. Don haka za mu yi wani abu game da tanadin makamashi mai ɗorewa, wanda kuma shine aikinmu don yin wannan abin. Tabbas, akwai kyakkyawan wuri don amfani dashi a cikin cascades. Ina tsammanin yin amfani da cascade yana da wasu darajar a cikin shekaru biyu da suka gabata, amma yana da mahimmanci a yi amfani da shi a nan gaba, amma kuma tunani game da ingancin caji da caji, da zarar farashin batirin ya faɗi, akwai wasu matsaloli tare da cascading. Rashin daidaituwa na iya warware manyan matsaloli. Wani nau'in babban modular ya rage farashin tsarin gaba ɗaya. Babban wanda zai iya inganta yawan amfani.

Kamar batirin da aka yi amfani da shi a cikin mota shekaru uku bayan haka, raguwa ba ƙasa da 8% ba, kuma yawan amfani shine kawai 60%. Saboda bambancinsa ne. Idan kayi saiti na amfani da kashi 5, zaku iya samun kashi 70%, wanda zai iya inganta yawan amfani. Aurawar igiyoyin baturi tare kuma zasu iya inganta amfanin baturi. Bayan an kiyaye, tanadin makamashi ya karu da kashi 33%.

 

Idan aka kalli wannan misalin, bayan daidaitawa, ana iya ninka shi da kashi 7%, bayan an daidaita kungiyar, Na karu da kashi 3.5%, kuma daidaituwa na iya karuwa da kashi 7%. Rungume masu sassauƙa na iya kawo fa'ida. A zahiri, dalilin raguwar masana'antun masana'antu daban-daban. Wajibi ne a san abin da wannan rukunin batirin zai zama ko abin da rarraba sigogi zai kasance, sannan kuma sai ku yi niyya mai kyau.

Wannan makirci ne wanda aka ɗauka, module ɗin yana da cikakken iko mai cin gashin kansa na yanzu, wanda bai dace da aikace-aikacen wutar lantarki ba.

Partangare na ikon module ɗin ana sarrafa shi da kansa. Wannan da'irar ta dace da matsakaici da kuma ƙarfin lantarki da kuma maimaitawa. Wannan shine maganin ajiyar batir na MMC wanda ya dace da babban ƙarfin lantarki da babban iko.

Hakanan game da yanayin nazarin baturi. A koyaushe ina cewa karfin batirin bai yi daidai ba, raguwa ba shi da tushe, tsufa batirin bai dace ba, kuma iyawar da karfin juriya yana ragu sosai. Yin amfani da wannan siga don rarrabewa, ƙari da kuke amfani dashi shine iyawa da juriya na ciki. Idan kana son samun hanyar kiyaye daidaito, kana buqatar bambance bambancen SOC na kowane batir, yadda zaka tantance SOC na wannan kwayar, sannan kuma zaka iya cewa yadda wannan batirin yake bai dace da kuma yadda iyakar karfin zai iya zama . Yaya za a sami SOC guda ta hanyar riƙe baturi ta hanyar SOC? Hanya ta yanzu ita ce sanya BMS akan tsarin batirin kuma kimanta wannan SOC akan layi a cikin ainihin lokaci. Muna son bayyana shi ta wata hanyar. Muna fatan gudanar da bayanan samfur zuwa bango. Muna bincika baturin SOC da baturin ta hanyar bayanan baya. DonH, inganta batirin a wannan tushen. Sabili da haka, muna fatan cewa bayanan batirin mota, ba manyan bayanai ba, shine matattarar bayanai. Ta hanyar koyon injin da ma'adanan ƙasa, ana fadada ƙimar kimar SOH, kuma an ba da dabarun gudanarwa don cikakken caji da zubar da tsarin baturi gwargwadon sakamakon ƙididdigar.

Bayan bayanan sun zo, akwai wani fa'idodi, zan iya yin gargadin farko game da lafiyar lafiyar batir. Wutar batir har yanzu tana faruwa akai-akai, kuma dole ne a amintar da tsarin kiyaye kuzari. Muna fatan yin cikakken bayanin lokaci da matsakaita da dogon lokacin gargadi ta hanyar bayanan bayanan asali, nemo hanyoyin gajeriyar hanya da dogon zango don haɗarin haɗari, kuma a ƙarshe inganta aminci da amincin tsarin duka.

Ta hanyar wannan, zan iya cimma fannoni da yawa a cikin babban sikelin, ɗayan shine don ƙara yawan amfani da makamashi na tsarin, na biyu shine don ƙara rayuwar batir, na uku shine tabbatar da aminci, kuma wannan tsarin adana makamashi na iya yin aiki da dogaro .

Nawa bayanan bayanan da nake buƙata don lodawa don biyan buƙatata? Ina buƙatar samun ƙaramin batirin da ya dace da yanayin batirin. Wadannan bayanan zasu iya tallafawa bincike a baya, bayanan bazai iya yin girma da yawa ba, adadi mai yawa a zahiri ya kasance babba ne ga dukkan hanyar sadarwa. Da yawa na milise seconds, kuna ɗaukar wutar lantarki da halin yanzu na kowane batir, wanda ba zai yiwu ba lokacin da kuka wuce shi a bango. Mun sami wata hanya yanzu, zamu iya fada muku, menene yakamata yakamata su zama, menene bayanan halayyar da kuke buƙatar wucewa kawai Muna matsa waɗannan bayanan, sannan kuma mu wuce zuwa cibiyar sadarwa. Tsarin aikin baturi shine millisecond ɗaya, wanda ya isa ya dace da bukatun kimantawar baturi. Bayanan bayananmu suna da yawa, kaɗan.

Lastarshe na ƙarshe, muna faɗi BMS, farashin ajiyar kuzari ya zama mafi mahimmanci fiye da farashin batir. Idan ka ƙara duk ayyukan zuwa cikin BMS, baza ku iya rage farashin wannan BMS ba. Tun da za a iya aiko da bayanai, za a iya samun dandamali mai zurfin bincike a bayana. Zan iya sauƙaƙa shi a gaban. Akwai kawai samfurin samfurori ko kariya mai sauƙi a gaban. Yi ƙididdigar SOC mai sauƙin sauƙi, ana aika sauran bayanai daga bango, wannan shine abin da muke yi yanzu, ƙididdigar jihohi da samammen samfuran BMS da ke ƙasa, mun ƙaddamar da mai kula da adana kuɗin wutar lantarki, kuma a ƙarshe wuce zuwa cibiyar sadarwa, makamashi. ajiya Mai kula da kumburi zai sami wani algorithm, abubuwan da ke gaba shine gano asali da daidaitawa. Ana yin lissafin karshe a hanyar sadarwar bango. Wannan shine tsarin tsarin gaba daya.

Bari muyi la'akari da inganci da saukin sauyin yanayin murfin ƙasa, wanda yake shine daidaitawa, ƙaramar wutar lantarki da kuma mallakar daidaituwa ga mallakar yanzu. Mai kula da kumburin kumburin kumburi yana gaya wa masu zuwa yadda ake mu'amala da shi, gami da SOC ana yi anan, kuma tushen yana aiki kuma. Wannan shi ne kaifin firikwensin, sashin sarrafa baturi, da kuma mai kula da hancin kaɗaici waɗanda muke aiki a yanzu, wanda ke rage farashin tanadin makamashi.
