LUVLED III – Optimierung eines Kühlkonzeptes zur Aktivluftkühlung eines Hochleistungs-UV-LED-Moduls
(2012)
Within the project SLOBATCO (Slovak-Bavarian Telescope Collaboration)
the Astronomical Institute of the Slovak Academy of Sciences and Aschaffenburg University of Applied Sciences collaborate in the development
and commissioning of scientific instrumentation for the new Ø1.3 m astronomical
telescope at the Skalnaté Pleso observatory. The joint project is funded by
the Bavarian Academic Center for Central, Eastern and Southeastern Europe
(BAYHOST). Planned technical work packages are targeting the filter wheel
software for the VIS camera, additional IR filters, and an upgrade of the mirror
coating facility by additional sputtering equipment.
The electric power supply of astronomical observatories has to manage a conflict of
interest: Observatories are situated at remote locations, they have a high consumption
of electric power while measuring electric signals as sensitively as possible.
Within the project SLOBATCO, the question did arise, to what extent observatories
have to rely on adequate power quality, for example, the perfectly sinusoidal shape
of supply voltage and current, to ensure safe operation and accurate measurement
results. International power quality standards are put in perspective with requirement
specifications for observatories. This contribution describes themotivation, the
underlying mechanisms that lead to issues, comments on the challenge in power systems
engineering, proposes the instrumentation and installation, and interprets the
first results. Experimental results clearly motivate the need for further measurement
campaigns, as power-quality-related problems are common. A summary is provided
together with an outlook and a motivation for future measurement campaigns.
