FP4-NNE-THERMIE C, Variable speed technology for low heat hydropower systems

Objective: Aim is to modify two small hydropower plants to variable speed operation in order to increase annual energy output by improved part load efficiency and design flow. A 100 kW vertical axis Francis turbine (Kaltenburg, DE) and a new 18 kW waterwheel (Bettborn, LU) will be modified to variable speed operation by use of a AC-AC converter. There will be installed a movable free-overfall weir at the waterwheel. By an expected increase of the electricity production in the range of 10 to 20 per cent , the aim is to proof viability of improving existing low head hydro sites with this technology. Especially low head sites have high variation of head and flow. Variable speed technology allows the system to operate at maximum efficiency for a wide range of hydraulic conditions. Modern power electronics replaces complex mechanical control systems with a high need for maintenance. In wind energy, variable speed technology has already proven its advantages compared to other mechanical technologies. General Information: Unlike earlier approaches with a combination of double regulated turbines and variable speed in a new installation, in this project the combination of a Francis turbine (respectively a water wheel) in existing plants together with a frequency converter will be used to increase part load efficiency and design flow of the system. Only the new IGBT controlled converters which are now used in wind energy as well as in motive power industry appliances can guarantee a reliable variable speed operation of a normal asynchronous generator. The combination of the movable weir and variable speed operation of the water wheel will allow to optimise the power output of the plant under all conditions. The use of an IGBT converter makes it possible to compensate reactive power to improve the mains performance. Due to detailed theoretical analysis and according to the positive experience with variable speed operation in wind energy and motive power technology, the expected increase of the annual power output of the two plants is in the range of 10 to 20 per cent of the actual value. This will reduce the specific cost of the electricity by the same range. For the actual payback tariffs of many European countries, this will increase the number of feasible low head sites. The top water level control by variation of turbine speed (and so flow) will be demonstrated to show a simple, reliable and energy saving alternative to the old hydraulic systems, which are still installed in many sites. The success of the variable speed system in this plants will open a big European SME market for cheap technological improvement of small hydropower plants and low head sites. The monitored performance of the plants data will be stored in a data logger with a modem, to allow automatic down-loading from a server-PC via modem. ...

Sentinel-5P TROPOMI - Aerosol Optical Depth (AOD), Level 3 - Global

Aerosol optical depth (AOD) as derived from TROPOMI observations. AOD describes the attenuation of the transmitted radiant power by the absence of aerosols. Attenuation can be caused by absorption and/or scattering. AOD is the primary parameter to evaluate the impact of aerosols on weather and climate. Daily AOD observations are binned onto a regular latitude-longitude grid. The TROPOMI instrument onboard the Copernicus SENTINEL-5 Precursor satellite is a nadir-viewing, imaging spectrometer that provides global measurements of atmospheric properties and constituents on a daily basis. It is contributing to monitoring air quality and climate, providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the top of atmosphere solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum. The operational trace gas products generated at DLR on behave ESA are: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4), together with clouds and aerosol properties. This product is created in the scope of the project INPULS. It develops (a) innovative retrieval algorithms and processors for the generation of value-added products from the atmospheric Copernicus missions Sentinel-5 Precursor, Sentinel-4, and Sentinel-5, (b) cloud-based (re)processing systems, (c) improved data discovery and access technologies as well as server-side analytics for the users, and (d) data visualization services.

Entwicklung einer Prüfinfrastruktur zur normativen Validierung dynamischer Vorgänge von netzbildenden dezentrale Erzeugungsanlagen, Teilvorhaben HBRS:Entwicklung und Laborprüfung von Prüfsequenzen für ein Prüf- und Testsystem zur Validierung von netzbildenden Anlagen

Das Teilvorhaben der H-BRS legt ihren Fokus auf die Entwicklung von Prüfsequenzen zur normativen Validierung dynamischer Vorgänge von netzbildenden Erzeugungsanlagen und die Laborprüfung der Prüfsequenzen. Hierfür sollen zunächst die Anforderungen an das Interface des Echtzeitsystems, beim Betrieb von netzbildenden Anlagen (NBAs), im Hinblick auf Stabilität, Genauigkeit und Grenzen analysiert werden. Darauf aufbauend werden Prüfsequenzen für eine Power Hardware-in-the-Loop (P-HiL) Umgebung entwickelt. Außerdem soll ein automatischer Testablauf, zum Abfahren der Prüfsequenzen und zur Automatisierung des Prüfsystems erstellt werden. Vor der Anwendung auf dem Gesamtsystem soll eine Vorvalidierung im kleinen Maßstab durchgeführt werden. Dazu werden die Anforderungen an das Gesamtsystem übernommen und ein Aufbau mit geringeren Leistungen und den entwickelten Benchmarknetzen vorbereitet. Die automatisierten Prüfsequenzen werden dann mit dem Konsortium geteilt, um den Gesamtaufbau zu realisieren. Ein weiteres Arbeitspaket befasst sich mit der dynamischen Verstärkereinheit. Hier soll ein Konzept zur Weiterentwicklung der Hardware erstellt werden. Das Konzept wird theoretisch untersucht und dann beim Aufbau des Hybridverstärkers umgesetzt. Für die Leistungsimpedanz wird die Hardwareentwicklung der Ansteuerung durch die H-BRS durchgeführt. Nach der Übergabe an das IEE wird die Auslegung der Regelung und der Laboraufbau zur Validierung begleitet. Zuletzt wird in Zusammenarbeit mit den anderen Projektpartnern die Labordemonstration des Gesamtsystems durchgeführt. Dabei wird die Interoperabilität der Stromrichter mit netzbildenden Eigenschaften untersucht und die Testsequenzen werden ausgewertet.

Quantification of the influence of current use fungicides and climate change on allochthonous Organic MATer decomposition in streams (QUANTOMAT)

The decomposition of terrestrial organic material such as leaf litter represents a fundamental ecosystem function in streams that delivers energy for local and downstream food webs. Although agriculture dominates most regions in Europe and fungicides are applied widely, effects of currently used fungicides on the aquatic decomposer community and consequently the leaf decomposition rate are largely unknown. Also potential compensation of such hypothesised adverse effects due to nutrients or higher average water temperatures associated with climate change are not considered. Moreover, climate change is predicted to alter the community of aquatic decomposers and an open question is, whether this alteration impacts the leaf decomposition rate. The current projects follows a tripartite design to answer these research questions. Firstly, a field study in a vine growing region where fungicides are applied in large amounts will be conducted to whether there is a dose-response relationship between the exposure to fungicides and the leaf decomposition rate. Secondly, experiments in artificial streams with field communities will be carried out to assess potential compensatory mechanisms of nutrients and temperature for effects of fungicides. Thirdly, field experiments with communities exhibiting a gradient of taxa sensitive to climate change will be used to investigate potential climate-related effects on the leaf decomposition rate.

Mineralogical, geochemical, microbiological and thermodynamic data from a deep hydrothermally altered profile of a semi-arid environment (Chilean Coastal Cordillera)

This data publication is supplementary to a study on microbial weathering of Fe-bearing minerals in the deep biosphere of a semi-arid environment (Chile). The dataset contains mineralogical, geochemical, microbiological and thermodynamic data of an 87 m deep drill core profile located in the Chilean Coastal Cordillera (Santa Gracia (SG)). The drilling campaign was conducted in March-April 2019 as part of the German Science Foundation (DFG) priority research program SPP 1803 “EarthShape: Earth Surface Shaping by Biota”. The project focused on how microorganisms contribute to mineral weathering and thus shape Earth´s surface. Aim of the drilling campaign was to recover the continuous weathering profile from surface to weathering front and to pinpoint as well as disentangle weathering processes at depth. For this purpose, extractable Fe pools, water-extractable organic carbon and nitrate, energy yields of Fe redox reactions, in situ microbial Fe(III) reduction, microbial Fe(III) reduction extent in microcosms, as well as community compositions of in situ and microcosms derived 16S rRNA gene amplicon sequence variants (ASVs) were determined.
