Is er et stort problem for vindm\u00f8ller i nordlige egne og koster millioner af euro \u00e5rligt. Et nyt forskningsprojekt skal udvikle autonome droner, der selv kan lokalisere is p\u00e5 m\u00f8llevinger. M\u00e5let er langt mere energioptimerede vindm\u00f8ller samt mulighed for vindm\u00f8llerplaceringer l\u00e6ngere nordp\u00e5.<\/strong><\/p>\n\n\n\n

Et nyt forskningsprojekt p\u00e5 Aarhus Universitet sigter efter at udvikle intelligente, autonome droner, der selv kan flyve ud, scanne, detektere og afrapportere, n\u00e5r der udvikler sig is p\u00e5 vingerne af vindm\u00f8ller i b\u00e5de sm\u00e5 og store vindm\u00f8lleparker.<\/p>\n\n\n\n

Projektet er st\u00f8ttet af Danmarks Frie Forskningsfond med 2,8 mio. kr. og ledes af lektor Erdal Kayacan fra Aarhus Universitet, Institut for Elektro og Computerteknologi. Projektet udf\u00f8res i samarbejde med Vestas.<\/p>\n\n\n\n

\u201dDet er satans sv\u00e6rt at detektere is p\u00e5 m\u00f8llevinger, prim\u00e6rt fordi is er gennemsigtigt. Men med projektet fors\u00f8ger vi os med flere forskellige indbyggede sensorsystemer p\u00e5 dronerne. Samtidig udvikler vi en AI-styret algoritme, der ved hj\u00e6lp af avanceret billedgenkendelse kan se forskel p\u00e5 m\u00f8llevinger med og uden isbel\u00e6gninger,\u201d siger han.<\/p>\n\n\n\n

Til-isning af m\u00f8llevingerne er i dag et signifikant problem. N\u00e5r vinteren s\u00e6tter ind og kulden breder sig, g\u00e5r det nemlig i h\u00f8j grad ud over vindm\u00f8llers energiproduktion, hvis der dannes is p\u00e5 vingerne. Isen kan reducere vindm\u00f8lleparkers \u00e5rlige energiproduktion med helt op til 80 pct.<\/p>\n\n\n\n

Is reducerer ikke kun vingenes aerodynamiske effektivitet, men \u00f8ger ogs\u00e5 belastningen og kan skabe uhensigtsm\u00e6ssige mekaniske vibrationer ved uj\u00e6vn til-isning. Sv\u00e6re forhold kan endda tvinge vindparker til nedlukning, hvilket kan koste vindenergi-industrien milliarder.<\/p>\n\n\n\n

\u201dDet er et stort problem for vindm\u00f8lleparker. Derfor opvarmer man i dag vingerne, men man g\u00f8r det blindt, for man kan ikke se, hvor til-isningen foreg\u00e5r. Dette projekt g\u00e5r ud p\u00e5 at udpege n\u00f8jagtigt hvilke vindm\u00f8ller, der er is p\u00e5, og hvor p\u00e5 m\u00f8llevingerne, isen er. Derefter kan man opvarme udelukkende lokalt, hvilket kan spare megen energi og dermed optimere driften,\u201d siger lektoren.<\/p>\n\n\n\n

Emre Yildiz, som er Simulation and Strategy Specialist hos Vestas, tilf\u00f8jer:<\/p>\n\n\n\n

“Med dette strategiske samarbejde sigter vi efter at l\u00e6gge grundlaget for st\u00f8rre ydelse fra turbinerne, l\u00e6ngere m\u00f8llelevetid og markedsudvidelse i koldere klimaer.”<\/p>\n\n\n\n

Ud over at spare p\u00e5 energi til un\u00f8dvendig opvarmning af m\u00f8llevinger regner forskerholdet med, at projektet vil g\u00f8re det muligt at udvide mulighederne for brug af vindenergi til mere nordlige egne end i dag. Eftersom vedvarende energi er n\u00f8dvendig for at efterkomme ambitionerne i Paris-aftalen, er det afg\u00f8rende at finde nye, levedygtige steder, selv i kolde klimaomr\u00e5der, til ny gr\u00f8n energiproduktion.<\/p>\n\n\n\n

“Projektet har s\u00e6rlig opm\u00e6rksomhed og st\u00f8tte fra Vestas-ledelsen og f\u00f8rer forh\u00e5bentlig til yderligere forsknings- og udviklingssamarbejde,” siger Emre Yildiz.<\/p>\n\n\n\n

Projektet skal teste droner med forskellige sensorer, herunder RGB-kameraer, termiske kameraer, LIDAR og ultralyd mv. Ideen er at finde den bedste kombination af forskellige teknologier og AI-algoritmer.<\/p>\n\n\n\n

\u201dVi regner med at kunne foretage den f\u00f8rste test p\u00e5 en off-shore vindm\u00f8lle til n\u00e6ste vinter, men f\u00f8rst skal vi regne p\u00e5 systemet og modellere os frem til den rette l\u00f8sning,\u201d siger Erdal Kayacan, som regner med, at et succesfuldt resultat kan have betydelig indvirkning p\u00e5 vindkraftindustrien som helhed.<\/p>\n\n\n\n

Projektet g\u00e5r under navnet \u2019Detecting Ice Using Artificial Intelligence-based Techniques\u2019 (DISTINCT) og starter til januar 2023.<\/p>\n\n\n\n
