J{\"u}lich durchgef{\"u}hrtes Forschungsprojekt „Blitzschutz f{\"u}r netz-autarke Hybridanlagen" machte es m{\"o}glich, sich mit dem Blitzschutz speziell solcher Anlagen n{\"a}her zu besch{\"a}ftigen. Vermehrt bekannt gewordene Schadensf{\"a}lle an nicht netz-gekoppelten Hybridanlagen waren der Ausl{\"o}ser, den Schutz zu {\"u}berdenken. Definiertes Ziel war es, f{\"u}r netz-autarke energietechnische Anlagen ein Konzept zum Schutz vor Blitzeinwirkungen zu erstellen. Diese Anlagen bestehen {\"u}blicherweise aus einer oder mehreren Photovoltaikanlagen, ggf. auch Solarthermieanlagen und einem oder mehreren kleineren Windgeneratoren (sie werden deshalb auch als Hybridanlagen bezeichnet). Zur Erh{\"o}hung der Versorgungssicherheit kann noch ein Dieselaggregat dazukommen. Hybridanlagen werden vor allem in Gebieten mit sehr schlechter {\"o}ffentlicher Energieversorgung eingesetzt, d.h. insbesondere in relativ d{\"u}nn bewohnten Gebieten und in Entwicklungsl{\"a}ndern. Dem Blitzschutz von Hybridanlagen kommt dabei eine steigende Bedeutung zu. Besonderes Augenmerk in dem genannten Forschungsprojekt sollte dabei auf die technisch/wirtschaftliche Ausgewogenheit des Schutzes gelegt werden: • die Schutzmaßnahmen sollen nur in solchen F{\"a}llen eingesetzt werden, wo dies als Ergebnis von Risikoanalysen sinnvoll erscheint; • f{\"u}r typische netz-autarke Hybridanlagen sollen die Schutzmaßnahmen ohne deutliche Verteuerung realisierbar sein (es soll also kein absoluter Schutz realisiert werden; ggf. soll lediglich der auftretende Schaden soweit m{\"o}glich minimiert werden). Dazu wurde in einem ersten Schritt zun{\"a}chst eine Aufnahme des Iststandes einiger typischer netz-autarker Hybridanlagen und deren einzelnen Komponenten durchgef{\"u}hrt. Aufgrund dessen wurde eine umfassende Risikoanalyse zur Blitzbedrohung dieser Anlagen auf der Basis von VDE V 0185 Teil 2:2002-11 [1] erstellt. Die Ergebnisse m{\"u}ndeten in ein technisch/wirtschaftlich ausgewogenes Konzept f{\"u}r den Anlagen- Blitzschutz (d.h. insbesondere dem Schutz vor direkten Blitzeinschl{\"a}gen und deren unmittelbaren Auswirkungen) nach VDE V 0185 Teil 3:2002-11 [2] und f{\"u}r den Elektronik-Blitzschutz (d.h. f{\"u}r den Schutz vor {\"U}berspannungen durch direkte, insbesondere aber auch indirekte Blitzeinschl{\"a}ge) nach VDE V 0185 Teil 4:2002-11 [3]. Aufgrund der gesammelten Ergebnisse konnten dabei allgemeine Empfehlungen f{\"u}r den {\"A}ußeren und Inneren Blitzschutz von regenerativen Energieerzeugungssystemen erstellt werden. Diese sollen in Schulungen einm{\"u}nden, die f{\"u}r Hersteller und Betreiber von Hybridanlagen angeboten werden. Durch die Anwendung wird der Schutz der Anlagen vor Blitzeinwirkung und elektromagnetischen St{\"o}rungen verbessert, was sich in einer reduzierten Ausfallwahrscheinlichkeit bzw. erh{\"o}hten Verf{\"u}gbarkeit wiederspiegelt. An einigen ausgew{\"a}hlten Anlagen werden mit Hilfe der im Projekt involvierten Industriepartner die Schutzmaßnahmen realisiert. Hierbei entstanden den Eigent{\"u}mern bzw. Betreibern der Anlagen keine Kosten. In diesem Beitrag werden beispielhaft drei Anlagenprojekte detailliert gezeigt.

The objective of this study was to experimentally determine the additional shielding effectiveness of a second reinforcement layer compared to a single-layer grid. To this end, simulated structures were set up in the high current laboratory. The structures consisted of cubic cages of 2 m side length with one or with two reinforcement grids, respectively. The structures were exposed to direct lightning currents representing the variety of anticipated lightning current waveforms.

Die Nutzung der Bewehrung ist dabei grunds{\"a}tzlich gleichermaßen bei Neubauten wie auch bei Ert{\"u}chtigungen m{\"o}glich und sinnvoll. So stellt die Nutzung der Bewehrung beispielsweise im Bereich von Großkraftwerken eine wesentliche Ert{\"u}chtigungsmaßnahme f{\"u}r den Blitzschutz elektrischer und elektronischer Einrichtungen dar: - Einerseits wird der Blitzschutz-Potentialausgleich durch den Anschluss metallener Einrichtungen wie Elektronik-Schr{\"a}nke, Kabeltrag-Konstruktionen, Rohrleitungen, etc. an die Bewehrung deutlich verbessert. - Andererseits kann bei gr{\"o}ßeren Geb{\"a}uden die elektromagnetische Schirmwirkung durch die elektrische {\"U}berbr{\"u}ckung von vorhandenen Dehnfugen bei Stahlbetonbauten optimiert werden. Diese Dehnfugen sind teilweise nur unzureichend {\"u}berbr{\"u}ckt, so dass bei Blitzeinschlag in das betreffende oder ein benachbartes Geb{\"a}ude an Kabelstrecken, die {\"u}ber die Dehnfuge hinwegf{\"u}hren, rel. hohe Spannungen induziert werden k{\"o}nnen [2, 3]. Die sich um das gesamte Geb{\"a}ude herumziehende oder zwischen zwei Geb{\"a}uden befindliche Dehnfuge muss deshalb im Abstand von maximal einigen Metern {\"u}berbr{\"u}ckt werden.

Der Blitzschutz von netz-autarken Hybridanlagen ist ein bislang noch vergleichsweise unzureichend bearbeitetes Fachgebiet. F{\"u}r große Windenergie-Anlagen (WEA) wurde in den letzten Jahren eine Zahl von FuE-Projekten durchgef{\"u}hrt, zum Großteil finanziert durch die {\"o}ffentliche Hand, zum kleineren Teil auch durch die Industrie, d.h. die WEAHersteller. Dabei wurden bestehende Defizite im Design der WEA festgestellt und Maßnahmen vorgeschlagen, die vor den mechanischen Zerst{\"o}rungen insbesondere des Rotors und vor den St{\"o}rungen und Zerst{\"o}rungen an den elektrischen / elektronischen Systemen der WEA weitgehend Schutz bieten [1, 2, 3]. Der Stand-der- Normung ist im Entwurf DIN VDE 0127 Teil 24 „Blitzschutz f{\"u}r Windenergieanlagen" (dt. {\"U}bersetzung des internationalen Drafts IEC 61400-24 „Wind turbine generator systems; Part 24: Lightning Protection") dokumentiert [4]. Die Maßnahmen sind allerdings insbesondere f{\"u}r gr{\"o}ßere WEA vorgesehen; im Falle kleinerer WEA lassen sie sich nur bedingt umsetzen. Trotzdem sind auch kleinere WEA rel. stark blitzeinschlaggef{\"a}hrdet, wenn sie auf einer Bergkuppe o.{\"a}. platziert werden. F{\"u}r solche kleinere WEA, wie sie bei Hybridanlagen {\"u}blicherweise Verwendung finden, m{\"u}ssen die Blitzschutzmaßnahmen aus der DIN VDE 0127 Teil 24 angepasst werden. F{\"u}r PV- und ST-Anlagen ist eine entsprechende Blitzschutz-Norm noch nicht in Sicht. Hier ist vor allem der Schutz gegen direkte Blitzeinschl{\"a}ge in die Anlage bzw. die Geb{\"a}ude noch nicht ausreichend beachtet. Blitzfangeinrichtungen sind oft nicht vorgesehen. In aller Regel hat man dabei bisher eine Ausf{\"u}hrungsform des Blitzschutzes realisiert, die prim{\"a}r einen Ferneinschlag ber{\"u}cksichtigt und die dabei entstehenden induzierten, rel. energieschwachen {\"U}berspannungen durch schw{\"a}chere Schutzelemente wie R{\"u}ckstromdioden, Bypassdioden und zum Teil thermisch {\"u}berwachte Varistoren begrenzt [5, 6, 7]. Diese Schutzelemente k{\"o}nnen allerdings bei Naheinschl{\"a}gen bzw. Direkteinschl{\"a}gen {\"u}berlastet und damit zerst{\"o}rt werden. Dar{\"u}ber hinaus k{\"o}nnen Nahoder Direkteinschl{\"a}ge auch zur Schw{\"a}chung der elektrischen Festigkeit der PVModulisolierung f{\"u}hren. Die Folge davon sind lokale extreme W{\"a}rmeentwicklungen, die sogar ein Schmelzen von Glas (sekund{\"a}rer Langzeiteffekt) hervorrufen k{\"o}nnten.

These damages (total number approx. 74000 cases), registered by five German insurance companies in 2005 and 2006, were adviced by customers as caused by lightning overvoltages. With the use of stochastical methods it is possible, to reasses the collected data and to distinguish between cases, which are with high probability caused by lightning overvoltages, and those, which are not. If there was an indication for a direct strike, this case was excluded, so the focus was only on indirect lightning flashes, i.e. only flashes to ground near the structure and flashes to or nearby an incoming service line were investigated. The data from the field contain the location of damaged apparatus (residence of the policy holder) and the distances of the nearest cloud-to-ground stroke to the location of the damage registered by the German lightning location network BLIDS at the date of damage. The statistical data along with some complementary numerical simulations allow to verify the correspondence of the Standards rules used for IEC 62305-2 with the field data and to define some correction needs. The results could lead to a better understanding whether a damage reported to an insurance company is really caused by indirect lightning, or not.}, subject = {Blitzschutz}, language = {en} } @inproceedings{KernBeierlZischank2009, author = {Kern, Alexander and Beierl, Ottmar and Zischank, Wolfgang}, title = {Calculation of the separation distance according to IEC 62305-3: 2006-10 - Remarks for the application and simplified methods}, year = {2009}, abstract = {[Paper of the X International Symposium on Lightning Protection 9th - 13th November, 2009 - Curitiba, Brazil. 6 pages] The international standard IEC 62305-3, published in 2006, requires as an integral part of the lightning protection system (LPS) the consideration of a separation distance between the conductors of the LPS and metal and electrical installations inside the structure to be protected. IEC 62305-3 gives two different methods for this calculation: a standard, simplified approach and a more detailed approach, which differ especially regarding the treatment of the current sharing effect on the LPS conductors. Hence, different results for the separation distance are possible, leading to some discrepancies in the use of the standard. The standard approach defined in the main part (Clause 6.3) and in Annex C of the standard in some cases may lead to a severe oversizing of the required separation distance. The detailed approach described in Annex E naturally gives more correct results. However, a calculation of the current sharing amongst all parts of the air-termination and downconductor network is necessary, in many cases requiring the use of network analysis programs. In this paper simplified methods for the assessment of the current sharing are presented, which are easy to use as well as sufficiently adequate.}, subject = {Blitzschutz}, language = {de} } @inproceedings{BehrensFrentzelKern2009, author = {Behrens, J{\"o}rg and Frentzel, Ralf and Kern, Alexander}, title = {Simulation der transienten Spannungsverl{\"a}ufe im Eigenbedarfsnetz eines Großkraftwerks bei einem kraftwerksnahen Blitzeinschlag in die Hochspannungs-Freileitung}, isbn = {978-3-8007-3197-8}, year = {2009}, abstract = {8.

However, in complex structures such as nuclear power plants, the safety or the risk depends also on the components associated with a system. The classical fault tree analysis gives an overall view of the failure and contains several subsystems to the main event, however, the interactions in the subsystems are not well represented. In order to represent the interaction of the components, a method suggested by Cimellaro et al. (2006) using multidimensional performance limit state functions to obtain the system fragility curves is adopted. This approach gives the possibility of deriving the cumulative fragility taking into account the interaction of the response of different components. In this paper, this approach is used to evaluate seismic risk of a representative electrical building infrastructure, including the component, of a nuclear power plant. A simplified model of the structure, with nonlinear material behavior is employed for the analysis in Abaqus©. The input variables considered are the material parameters, boundary conditions and the seismic input. The variability of the seismic input is obtained from selected ground motion time histories of spectrum compatible synthetic ccelerograms. Unlike the usual Monte Carlo methods used for the probabilistic analysis of the structure, a computationally effective response surface method is used. This method reduces the computational effort of the calculations by reducing the required number of samples.}, language = {en} } @inproceedings{MilijašŠakićMarinkovićetal.2021, author = {Milijaš, Aleksa and Šakić, Bogdan and Marinković, Marko and Butenweg, Christoph}, title = {Experimental investigation of behaviour of masonry infilled RC frames under out-of-plane loading}, series = {Proceedings of COMPDYN 2021}, booktitle = {Proceedings of COMPDYN 2021}, editor = {Papadrakakis, Manolis and Fragiadakis, Michalis}, publisher = {National Technical University of Athens}, address = {Athen}, isbn = {978-618-85072-5-8}, issn = {2623-3347}, doi = {10.7712/120121.8528.18914}, pages = {829 -- 846}, year = {2021}, abstract = {Masonry infills are commonly used as exterior or interior walls in reinforced concrete (RC) frame structures and they can be encountered all over the world, including earthquake prone regions.

The analysis of such building aggregates is very challenging and modelling guidelines missing. Advances in the development of analysis methods have been impeded by the lack of experimental data on the seismic response of such aggregates. The SERA project AIMS (Seismic Testing of Adjacent Interacting Masonry Structures) provides such experimental data by testing an aggregate of two buildings under two horizontal components of dynamic excitation. With the aim to advance the modelling of unreinforced masonry aggregates, a blind prediction competition is organized before the experimental campaign.

Many institutions and enterprises, specifically in commerce, have already tried to establish sustainable diversity management concepts, in order to increase the diversity of their workforce in addition to establishing a corporate culture of openness. Alongside the creation of a working place where different experiences and skills are valued equally, the entrepreneurial intention is to transfer diversity into economically relevant advantages. Taking into account the potential of diversity in research and innovation processes, the project "Diversity- and Innovation Management" was incorporated within a large interdisciplinary research Cluster. The project's purpose was to study the context between diversity and innovation in research associations and to later develop a customised management concept into an interdisciplinary research Cluster on integrative production technology with full integration. The challenge of such research associations lays in an organisational structure which is often described as being decentralised. Researchers coming from different academic disciplines, while having diverse habits, conduct research on large scientific issues and challenges. In addition, these researchers are socialised in different institutions and university chairs. Theses differences in leadership styles, business cultures and organisational strategies, follow into their research team work. Taking a closer look into the management of human resources suggests that decentral organised recruitment processes, as well as allocation of human resources, lead to a lacking overview in regard to missing competencies, perspectives and backgrounds in research networks. These circumstances are comparable to big corporate groups. While developing a management concept for research associations, these characteristics must be considered. To ensure this, the project follows a human-centred approach, which considers top-down, as well as bottom-up perspectives. This paper presents the applied mixed-method approach in the scientific issue described above. In the frame of the Cluster of Excellence "Integrative Production Technology for High-Wage Countries" research results based on quantitative, as well as qualitative studies, were presented as an application example. This paper provides a new perspective on the innovation and diversity context.

A PV field can supply the power for the HT HP, thus effectively storing the PV power as thermal energy. Besides cost-efficiently storing energy from the PV field, the power block efficiency of the overall system is improved due to the higher steam parameters. This paper presents a technical assessment of Brayton cycle heat pumps to be integrated in hybrid PV-CSP power plants. As a first step, a theoretical analysis was carried out to find the most suitable working fluid. The analysis included the fluids Air, Argon (Ar), Nitrogen (N2) and Carbon dioxide (CO2). N2 has been chosen as the optimal working fluid for the system. After the selection of the ideal working medium, different concepts for the arrangement of a HT HP in a PV-CSP hybrid power plant were developed and simulated in EBSILON®Professional.

By intelligently combining Photovoltaics (PV) systems with CSP, a further cost reduction of solar power plants is expected, as well as an increase in dispatchability and flexibility of power generation. PV-powered Resistance Heaters (RH) can be deployed to raise the temperature of the molten salt hot storage from 385 °C up to 565 °C in a Parabolic Trough Collector (PTC) plant. To avoid freezing and decomposition of molten salt, the temperature distribution in the electrical resistance heater is investigated in the present study. For this purpose, a RH has been modeled and CFD simulations have been performed. The simulation results show that the hottest regions occur on the electric rod surface behind the last baffle. A technical optimization was performed by adjusting three parameters: Shell-baffle clearance, electric rod-baffle clearance and number of baffles. After the technical optimization was carried out, the temperature difference between the maximum temperature and the average outlet temperature of the salt is within the acceptable limits, thus critical salt decomposition has been avoided.
