A cikin tsire-tsire na PV, hanyoyin sadarwar fiber suna da alhakin watsa bayanan aiki daga kowane inverter zuwa tsarin sa ido na tsakiya. Idan hanyar haɗin fiber ta katse, tsarin sa ido ba zai iya samun bayanan inverter ba - ma'ana ƙungiyar ayyukan shuka ta PV ba za su iya sanin wanne inverter ke da matsala ba, menene fitarwar wutar lantarki, ko kuma yadda ya dace ya zama al'ada. Don injin PV 100MW tare da yuwuwar ɗaruruwan inverter, idan duk hanyoyin haɗin fiber sun katse, ƙungiyar ayyukan dole ne su warware matsalar inverter ta inverter, akan farashi mai yawa.
Hanyoyin haɗin fiber shuka na PV suna fuskantar ƙalubale na musamman na muhalli. Na farko: yawan zafin jiki na yanayi - tsire-tsire na PV yawanci ana gina su a wurare masu buɗewa, tare da yanayin zafi na ƙasa na rani ya wuce 60 ° C, kuma fiber yana haɓaka tsufa a yanayin zafi. Na biyu: UV fallasa - polyester buffer Layer na fiber ragewa a karkashin UV radiation, haddasa fiber embrittlement. Na uku: Tauna dabba - ramukan igiyoyi da fiber na sama a cikin tsire-tsire na PV sune manufa mai kyau ga rodents. Na hudu: iska da yashi - a cikin hamada da tsire-tsire na gobi PV, iska da yashi na iya kawar da zaren waje.
Don haka, yakamata a haɗa gwajin fiber shuka PV a cikin tsarin kulawa na yau da kullun. A lokacin karɓar sabon shuka, gwada kowace hanyar haɗin fiber ta watsa wutar lantarki, karɓar wuta, da asarar haɗin haɗin gwiwa. Yayin sabis, gwada ƙarfin haɗin gwiwa mai mahimmanci da asarar kwata. Bayan kuskure, yi amfani da tushen hasken ja don gano wurin hutun farko, sannan yi amfani da OPM don tabbatar da gyara.
Tsarin ƙaddamar da tsarin PV shine taga mai mahimmanci don gwajin fiber. A wannan mataki, duk hanyoyin haɗin fiber sababbi ne, kuma bayanan gwaji na iya zama 'tushen lafiya' - ana iya kwatanta sakamakon gwajin nan gaba da wannan tushe.
Daidaitaccen aikin ƙaddamar da aikin shine kamar haka. Mataki na daya: shirye-shiryen gwaji kafin gwaji. Tabbatar da tsawon zangon OPM 档位 yayi daidai da tsawon tsarin (yawanci 1310nm ko 1550nm); duba tsaftar ƙarshen fuskar fiber; tabbatar da nau'in adaftar ya dace da ƙirar fiber. Mataki na biyu: gwajin watsa-gefe. Haɗa OPM zuwa gefen watsa fiber (yawanci fitarwa na maɓalli ko na'urar gani) kuma karanta ikon watsawa. Mataki na uku: gwajin-gefen karɓa. Haɗa OPM zuwa gefen karɓar fiber (yawanci shigar da wani canji ko tsarin gani) kuma karanta ikon karɓar. Mataki na hudu: lissafin asarar haɗin haɗin gwiwa. Karɓar ƙarancin wutar lantarki yana daidai da asarar hanyar haɗin gwiwa. Mataki na biyar: tabbatar da hasken ja. Canja zuwa yanayin haske ja kuma duba hanyar fiber don hutu. Mataki na shida: Yi rikodin duk bayanai, adana su azaman tushe.
A lokacin ƙaddamarwa, mataki mai sauƙi wanda ba a manta da shi ba shine gwada duk abubuwan da ake buƙata. Firam ɗin rarraba fiber a cikin shuke-shuken PV yawanci suna da filaye masu amfani - waɗannan ƙila ba sa aiki da farko amma ana iya buƙata a nan gaba. Idan an sami kayan fiber ɗin da aka samu karye lokacin da ake buƙata daga baya, farashin magance matsalar zai yi nisa fiye da gwada shi a yanzu.
A gwajin filin shuka na PV, wuraren aiki da yawa na iya inganta inganci da daidaito sosai. Na farko: 'tsabta kafin gwaji.' Kurar fuskar fiber na ƙarshe shine mafi yawan sanadin sakamakon gwajin da ba na al'ada ba. Kafin kowane gwaji, duba ƙarshen fuska tare da ruwan tabarau mai girma; idan datti, tsaftace tare da sandar tsaftace fiber da barasa mara kyau. Wannan mataki mai sauƙi yana guje wa adadi mai yawa na rashin ganewar asali.
Na biyu: 'gwada duka zaruruwa.' A cikin hanyar haɗin fiber, yawanci akwai zaruruwa guda biyu - ɗaya don watsawa (Tx), ɗaya don karɓa (Rx). Asarar hanyar haɗin gwiwa na iya bambanta tsakanin su biyun. Gwaji ɗaya kawai da zana ƙarshe na iya rasa matsaloli tare da ɗayan. Hanyar da ta dace ita ce gwada duka biyu kuma kwatanta bambancin asarar. Idan bambance-bambancen ya wuce 3dB, fiber ɗaya na iya samun lankwasawa, murƙushewa, ko batutuwan ƙarewa.
Na uku: 'yi rikodin yanayin yanayi.' Asarar fiber ya dogara da zafin jiki - kowane canjin 10°C na iya canza asarar fiber ta kusan 0.1dB/km. Ba tare da yin rikodin yanayin yanayi ba yayin gwaji, bincike na gaba ba zai iya tantance ko canje-canjen asara yana nuna tsufa na fiber ko bambancin zafin jiki ba.
Na hudu: 'alama mahaɗin da ba na al'ada ba.' Bayan gwaji, yi alama duk hanyoyin haɗin gwiwa tare da asarar da ta wuce 1.5 × ƙimar ƙira, ɗaukar wuraren da ba na al'ada ba, kuma bin su. Kada ku lura da su a kan takarda kawai - loda hotuna zuwa tsarin sarrafa injiniya don tabbatar da cewa bayanan ba su ɓace ba.
Na biyar: 'kwatanta lokaci-lokaci.' Bayan kowace gwaji, kwatanta bayanan yanzu tare da bayanan gwajin baya. Idan asarar hanyar haɗin yanar gizo ta tashi sosai a cikin ɗan gajeren lokaci (wuta 3dB), yana iya yin lankwasawa, murƙushewa, ko ƙarewar tsufa, kuma yakamata a shirya matsala.
Na shida: 'gwajin kayayyakin zaruruwa lokaci-lokaci.' Zaɓuɓɓukan da za a yi amfani da su, ko da yake ba su aiki a halin yanzu, ya kamata a gwada su kowane watanni shida - don tabbatar da cewa sun shirya lokacin da ake bukata.
Babban dalilin gwajin fiber shine don jagorantar yanke shawarar ayyuka. Bayanan gwaji ba su da ƙima har sai an canza su zuwa aikin ayyuka. Saboda haka, rufe madauki daga bayanan gwaji zuwa yanke shawara na aiki shine ainihin tsarin kula da fiber.
Kulawar fiber ɗin da aka sarrafa bayanai ya haɗa da yadudduka uku. Layer daya shine ' faɗakarwar bakin kofa' - lokacin da asarar hanyar haɗin yanar gizo ta wuce matakin da aka saita, tsarin ta atomatik yana faɗakar da ƙungiyar aiki don shirya matsala. Layer na biyu shine 'bincike na al'ada' - ta hanyar kwatanta bayanan tarihi, gano hanyoyin haɗin kai tare da hauhawar hauhawar asarar da ba a saba gani ba da jadawalin kiyayewa a gaba. Layer uku shine 'kyarwar tsinkaya' - ta hanyar dacewa da yanayin asara-da-lokaci, tsinkaya ragowar rayuwar hanyar haɗin gwiwa da jadawalin maye gurbin kafin gazawar.
Don cimma waɗannan matakan uku, ana buƙatar cikakken tarihin lafiyar fiber. Kowace ma'ajiya ta hanyar haɗin yanar gizo ta haɗa da: lambar hanyar haɗin gwiwa, farawa da ƙarshen wurare, nau'in fiber, tsayin tsayi, asarar ƙira, bayanan gwajin tarihi (kwanatin, watsa wutar lantarki, karɓar wuta, asarar haɗin gwiwa, zafin yanayi), bayanan rashin daidaituwa, da sakamakon ƙuduri. Yi amfani da ƙwararrun software na sarrafa fiber gwajin don sarrafa wannan bayanan - Excel ya dace da ƙananan ma'auni (dubun hanyoyin haɗin gwiwa), yayin da software na sarrafa ƙwararru ya dace da ma'auni mafi girma (daruruwan zuwa dubunnan hanyoyin haɗin gwiwa).
Ga ƙungiyoyin injiniya na PV, kafa ƙa'idodin gwajin fiber daga farkon aikin - kar a jira har sai isar da aikin zuwa补课. Tushen kiwon lafiya na fiber da aka kafa yayin lokacin ƙaddamar da tsarin suna aiki azaman ma'auni na ayyuka na shekaru goma masu zuwa. Ba tare da tushe ba, bayanan gwaji na gaba ya rasa ma'anar kwatanta.
Ga masu siye, lokacin zabar kayan gwajin fiber, kar a kwatanta farashin sayayya na farko kadai.
