Ilo PV plant ko, fiber communication link ko rej eddo in jilkinlok melele ko jen kajjojo inverter ñan central monitoring system eo. Elañe juon fiber link ej bōjrak, monitoring system eo ejjab maroñ bōk melele ko jen inverter eo — melelein bwe PV plant operations team eo ejjab maroñ in jelā ewi inverter eo ewōr an jorrāān, ta joñan kajoor eo ej walok, ak elañe efficiency eo ej jimwe.

PV Plant Fiber Links: Etke rej aorōk jen am lemnok

Ilo PV plant ko, fiber communication link ko rej eddo in jilkinlok melele ko jen kajjojo inverter ñan central monitoring system eo. Elañe juon fiber link ej bōjrak, monitoring system eo ejjab maroñ bōk melele ko jen inverter eo — melelein bwe PV plant operations team eo ejjab maroñ in jelā ewi inverter eo ewōr an jorrāān, ta joñan kajoor eo ej walok, ak elañe efficiency eo ej jimwe. Ñan juon 100MW PV plant eo ewōr buki inverter ko ie, elañe aolep fiber link ko rej bōjrak, tiim in jerbal eo ej aikuj in kōmman bwe en wor inverter kin inverter, ilo juon wōnan eo elap.

PV plant fiber links rej jelmae apan ko reoktak jen don. Mokta: joñan bwil im molo eo elap — PV plant ko rej kalek ilo jikin ko rebin, im joñan bwil im molo in bwidej ilo summer ej laplok jen 60°C, im fiber ej kōmman bwe en mõkaj an rūttolok ilo joñan bwil im molo ko reutiej. Kein karuo: UV exposure — polyester buffer layer in fiber ej jorrāān iumwin UV radiation, im kōmman an fiber eo rup. Kein kajilu: menin mour ko rej mōñā — cable trench ko im fiber ko ilo PV plant ko rej jikin ko remman ñan rodents ko. Kein kajilu: kōto im bok — ilo āne jemaden im gobi PV plant ko, kōto im bok remaroñ kōmman bwe en rup kilin fiber eo.

Kin menin, test in fiber in PV plant ej aikuj in bed ilo karōk in kōjparok eo. Ilo ien bōk menin eddek ko rekãl, mālejjone kajjojo fiber link ko rej maroñ in jilkinlok, maroñ in bōk, im jako in link ko. Ilo ien jerbal, test kajoor in link eo elap tokjen im joñan an jako kajjojo quarter. Elikin juon jorrāān, kōjerbal meram eo emera ñan pukōt jikin eo ear jorrāān mokta, innem kōjerbal OPM eo ñan lale bwe en emman.

Fiber Testing Workflow ilo ien jerbal in PV System

Iien jinoe PV system ej juon ien eo elap tokjen ñan test fiber. Ilo ien in, aolep fiber link ko rej kab jino, im data in test ko remaroñ jerbal einwot juon 'health baseline' — tokjen test ko ilju jeklaj remaroñ keidi ibben baseline in.

Wāween jerbal in kōmman jerbal ej einwot in. Bun̄tōn eo juon: kōppopo m̧okta jān test eo. Kamool bwe OPM wavelength档位 ej ekkar ñan wavelength eo an system eo (ekkā an 1310nm ak 1550nm); lale erreo eo an fiber end-face; lale bwe kain adapter eo ej ekkar ñan fiber interface eo. Bun̄tōn eo kein karuo: mālijjon̄ in transmit-side. Kobaik OPM eo ñan jikin eo an fiber eo (ekkā an output eo an juon switch ak optical module) im riiti kajoor in transmit eo. Bun̄tōn kein kajilu: mālijjon̄ in bōk-side. Kobaik OPM eo ñan jikin bōk fiber eo (ekkā an bar juon switch ak optical module) im riiti kajoor in bōk eo. Bun̄tōn eo kein kajilu: kalōk link eo ej jako. Kajoor in bōk jolok kajoor in jilkinlok ej joñan wōt an jako link eo. Bun̄tōn eo kein ka ļalem: kam̧ool kōn meram eo emera. Oktak ñan red light mode im lale ial in fiber eo ñan an rup. Bun̄tōn eo kein kajiljilimjuon: rekoote aolep data ko, likūt āinwōt baseline eo.

Ilo ien kōmman jerbal, juon men eo ejjab lukkun alikar ej test aolep spare fiber ko. Fiber distribution frame ko ilo PV plant ko ekkã air wõr air fiber ko jet — men kein remaroñ jab jerbal ilo jinoin ak remaroñ aikuj ilo ilju jeklaj. Elañe juon fiber ej rup ñe ej aikuj tokelik, wōnāān ñan kōmman jorrāān enaj laplok jen am test e kiõ.

Lalem jikin jerbal ko ñan mālijjon ilo jikin kallib

Ilo PV plant field testing, elōn jikin jerbal ko remaroñ lukkun kōkōmanmanlok jerbal im jimwe. Mokta: 'karreo mokta jen am test.' Fiber end-face dust ej un eo elaptata an walok tokjen test ko rejjab jimwe. Mokta jen kajjojo test, lale jemlokin mejān kin juon magnifying lens; elañe ettoon, karreo kin juon kein karreo im alcohol eo ejelok dren ie. Bun̄tōn in epidodo ej bōbrae elōn̄ bōd in kōmeļeļe ko.

Kein karuo: 'māllejoñ fiber ko ruo.' Ilo juon fiber link, ewōr ruo fiber ko — juon ñan transmit (Tx), juon ñan bōk (Rx). Link loss emaron oktak ikõtan men kein ruo. Test juon wōt im bōk jemlok ko emaron likjab in walok abañ ko ibben eo juon. Wāween eo ejimwe ej ñan test erro jimor im keidi oktak in jorren eo. Elañe oktak eo ej laplok jen 3dB, juon fiber emaron wor an jorrāān, rup, ak jemlok.

Kein kajilu: 'rekoote joñan bwil im molo in mejatoto.' Jako in fiber ej pedped wōt ioon joñan bwil im molo — kajjojo 10°C oktak emaron ukōt jako in fiber kin enañin 0.1dB/km. Ilo an ejelok rekoot in joñan bwil im molo ilo ien test eo, etale ko tokelik rejjab maroñ in kwalok elañe oktak ko ilo jako rej kwalok kin an rittolok fiber ak oktak in joñan bwil im molo.
