Test of voltage fault on wind turbine on ValsnesetThis winter NOWITECH conducted a controlled field experiment of voltage dips affecting a 2.5 MW Enercon wind turbine at Valsneset, using the DipLab facility. Wind speeds around 15 m/s ensured that the wind turbine was operating close to rated power. A number of voltage dips were imposed using the mobile test facility without significantly affecting the rest of the grid, and detailed electrical measurements were made and stored for later analysis. This experiment was a follow-up of a previous test in March 2014 in low wind conditions. The Enercon turbine has a full converter interface to the grid and is able to operate through such voltage faults, something this experiment confirmed. Although this was as expected, the detailed measurements, both on the electrical and mechanical sides are important for validation of simulation models. This is an on-going research activity that will continue in the summer and autumn of 2015. Contact: Harald Svendsen |

International Collaboration for Floating Wind InnovationA major international collaborative project involving 12 partners from eight countries and worth €7.3 million is set to drive forward development of the next generation of floating wind substructures. The European Horizon2020-funded programme LIFES50+, led by Norway’s MARINTEK (and involving Politechnico de Milano, DTU, Ramboll, ORE Catapult, Universität Stuttgart, Iberdrola I&C, Ideol, DNV GL, Tecnalia, Insitut de Recerca en Energia Catalunya and Dr.Techn. Olav Olsen), will run for 40 months and will focus on proving the innovative technology that is being developed for floating substructures for 10MW wind turbines at water depths greater than 50m.

Prof. Dr. Hans-Gerd Busmann from Fraunhofer has held a residency for three months at NOWITECH, where he has been collaborating with John Olav Tande and Thomas Welte. - The most important advice I could offer to Norwegian wind power enthusiasts would be that all the consequences for the entire energy system must be studied before large wind farms are erected. By doing so, you will eliminate delays and added costs that we experienced as a fresh ‘green energy nation,’ says a German wind power professor. The experienced German wind power expert Hans-Gerd Busman has completed a three-month guest stay with SINTEF Energy Research. The backdrop to his visit is the heavy investments made by Norway in knowledge and technology development for offshore wind power - largely through the NOWITECH and NORCOWE research centres for environmentally friendly energy.

Norway-Japan Energy Science Week gikk av stabelen i Tokyo siste uka i mai og representanter for forskningsinstitusjoner, myndigheter og universiteter fra hele Norge var representert. Målet med Energy Science Week var å utforske måter å øke samarbeidet mellom Norge og Japan innen FoU, høyere utdanning og i næringslivet/industrien.
På timeplanen var møter med japanske forskningsmyndigheter, konferanser, mottakelser, befaringer og bilaterale møter. Arrangementet var planlagt i et tett samarbeid mellom Norges Forskningsråd, Innovasjon Norge, Den norske ambassaden i Tokyo og de norske forskningsmiljøene. SINTEF var sterkt involvert og hadde ansvaret for flere sesjoner.

- Hvis huset ditt brenner, kan ikke brannfolk krangle om de skal slukke med vann, pulver, vanntåke eller halon. Alle slukkemidler trengs. Det samme gjelder for klimaet, skriver John Olav Tande og Nils Røkke i SINTEF i en kronikk i Adressa 17.06.2015. Read more. |
Denne kronikken var først på trykk i Dagens Næringsliv 11.06.2015 Massiv overgang til elbiler vil være en gavepakke for et kraft-Norge som åpenbart sliter med å finne vindkraftkunder. Paradoksalt nok ble nyheten om Statkrafts nei til midt-norske vindparker sluppet i ei uke som var full av støy rundt Norges elbil-satsing. Tradisjonelt har mange tenkt at vindturbinene må være på plass …

48 norske forskningsinstitutter mottar statlig basisfinansiering. SINTEF Energi AS er et av disse instituttene. Basisfinansieringen brukes til aktiviteter som bidrar til langsiktig kunnskapsutvikling og er med på å utvikle fremtidens forskningsområder. Her er et eksempel på et prosjekt som er finansiert gjennom basisfinansieringen: NanoHX
Bloggere: Eskil Aursand, Magnus Aashammer Gjennestad, Karl Yngve Lervåg, Halvor Lund
Vi på SINTEF Energi jobber for tida med et konsept der vi vil bedre kjøling av transformatorer ved hjelp av magnetiske nanopartikler.
Hvorfor det?
Jo, dette kan gjøre blant annet offshore vindmøller og subseafabrikker rimeligere å bygge, mer robuste og enklere å vedlikeholde.
