On the 8th of August, the Power Electronics Chair celebrated another milestone in the medium-voltage laboratory construction project.
The external power station was delivered by heavy transport and placed on the foundation. It includes a room with three medium-voltage switchgear, a room with a 10kV / 10kV isolation transformer (100kVA) and a room with a 10kV / 0.4kV transformer. This was preceded by elaborate earthworks to prepare the loamy surface for the high load. Since it had to wait for a release of the ordnance clearance service and the earthworks were accompanied by a combat probe, the construction project was delayed by several months.
The next steps will be follow-up works and connection works of the transformer station.
Next week, a recooler will be placed on the roof of the station and integrated into the prepared cooling system. Then another 6 weeks are planned for connection work, followed by another 2 weeks of work for programming and acceptance.
In the best case, a transfer of the medium-voltage laboratory would therefore be realistic in the beginning / middle of October.

Bereits zum 11. Mal in Folge veranstaltete der Lehrstuhl für Leistungselektronik die Veranstaltung „Power Girls & Boys Tage“, um Schüler der 5. und 6. Klassen für technische Sachverhalte zu motivieren. Für die beliebte Veranstaltung hatten sich diesmal fast 60 Kinder beworben, so dass die 30 Teilnehmer/Innen ausgelost werden mussten. Am 26. und 27. Juli war es dann soweit, dass die Kinder kurz vor dem Start der Sommerferien an der Technischen Fakultät der Christian-Albrechts-Universität zu Kiel zu Gast waren.
Den ersten Vormittag verbrachten die Nachwuchswissenschaftler mit einer Theorieeinheit. Begonnen wurde mit einer Einführung über Strom, Spannung und Leistung. Die anschließende Erklärung über Stromkreise, Dioden und LEDs führte dazu, dass fleißig diskutiert wurde. Anschließend wurden mit den Kindern die verschiedenen Arten erneuerbarer Energien besprochen und der preisgekrönte Film „Solarenergie-Spezial“ von Armin Maiwald aus der Sendung mit der Maus gezeigt. Hierbei zeigte sich die große Motivation sowie das Interesse der Kinder, die Sachverhalte tiefgründig zu verstehen. Das dabei erworbene Wissen wurde im Anschluss praktisch angewandt, indem eine kleine Schaltung, die „TicTac-Taschenlampe“ von jedem Kind selbst zusammengebaut wurde. Zuvor gab es eine parktische Einführungs in das Löten, bei dem jedes Kind aus Widerständen seine Initialien auf eine Lochrasterplatine löten sollte.
Im nächsten Projekt wurde es schon deutlich schwieriger: Eine Platine sollte selbstständig von den Kindern komplett mit Komponenten bestückt werden und am Ende ein blinkendes Herz darstellen. Dabei mussten die Kinder den filigranen Umgang mit dem Lötkolben lernen und auch die Polarisierung der Bauelemente beachten.
Die erworbenen Kenntnisse über die Solarzelle konnten am zweiten Tag in der Praxis angewendet werden, indem von jedem Kind eine selbstgebaute kleine Windmühle gebastelt wurde, deren Motor durch eine Photovoltaikzelle angetrieben wird.
Überraschenderweise waren die Power Kids so begeistert dabei, dass von der Möglichkeit zum Spielen in der Pause von der großen Mehrheit kein Gebrauch gemacht und stattdessen lieber weiter gearbeitet wurde. „Teilweise mussten wir die Kinder mehrfach deutlich bitten eine Trinkpause einzulegen, damit bei den hochsommerlichen Temperaturen von 33 Grad niemand umkippt“, schmunzelt Organisator Max Lutz vom Lehrstuhl für Leistungselektronik.
Um das Spielerische jedoch nicht vollkommen außen vor zu lassen, wurde im letzten Projekt ein elektrischer Draht gebaut, den die Kinder komplett selbst entwerfen und formen durften.
Insgesamt freuen wir uns über die positive Resonanz der Kinder und ihrer Eltern, die uns während aber auch im Anschluss an die Veranstaltung per Mail erreichte. Zurück in die Schule wollte nach zwei Tagen niemand.
Ein großes Dankeschön geht in diesem Jahr an die Sponsoren WEB-Andresen, SH Netz, Nord Electronic Drivesystems, FT Cap, Siemens sowie den Förderverein der Technischen Fakultät, die die Aktion durch Finanz- oder Sachspenden unterstützen. Diesen Dank möchten wir insbesondere im Namen der Kinder und ihrer Eltern aussprechen.

"KielFlex" soll das Stromnetz intelligent steuern
Kiel im Jahr 2035: Die meisten Menschen in der Stadt haben ihre Autos mit Verbrennungsmotoren inzwischen gegen ein Fahrzeug mit Elektroantrieb ausgetauscht. Kurierdienste und Pendler setzen auf Elektrofahrräder oder elektrisch betriebene Kleinfahrzeuge, und die Kieler Verkehrsgesellschaft schickt ausschließlich vollelektrische Busse auf die Straßen. Und auch viele Unternehmen, wie zum Beispiel die Kieler Stadtwerke, haben ihre Fahrzeugflotte inzwischen komplett elektrifiziert. Sogar die meisten Kreuzfahrtschiffe, die im Kieler Seehafen anlegen, schalten ihre Dieselmotoren ab und nutzen das Landstromangebot.
Stromversorger stehen vor großen Herausforderungen
So oder so ähnlich wird sich die Mobilität in Kiel in den nächsten Jahren entwickeln. Da sind sich viele Experten sicher: Vor allem die Diskussion über Stickoxide, Feinstaub und Diesel-Fahrverbote wird den Verbrennungsmotor nach und nach verdrängen und dem Elektroantrieb den Weg bereiten. Diese Revolution der Mobilität stellt aber vor allem die Stromversorger vor neue Herausforderungen. Statt an die Tankstelle müssen die E-Fahrzeuge an die Steckdose - doch die vorhandenen Stromnetze reichen dafür nicht aus. read more

So erklärten die Stadtwerke Kiel am Montag ihre Absichten für das Projekt, dessen Bandbreite wirkmächtig erscheint: Die Christian-Albrechts-Universität Kiel, das Energieunternehmen ABB AG Mannheim, das Fraunhofer-Institut in Magdeburg, die Landeshauptstadt und ihre Unternehmen Kieler Verkehrsgesellschaft (KVG), Seehafen sowie Stadtwerke wollen an einem Strang ziehen, um ein "intelligentes und flexibles Stromnetz" zu erstellen, so die Erklärung.
Binnen zwei Jahren will das Projekt Kielflex Antworten liefern: "Wir wollen das Kieler Stromnetz noch flexibler steuern und darüber Wege finden, die neuen Lasten intelligent in die bestehenden Netze zu integrieren", sagt Henning Schröer, Abteilungsleiter in der Stadtwerke-Netzgesellschaft. Ein Teil der Lösungen sollen kleine Speicher in Ladestationen sowie "Dämpfungslasten" sein.
Im Mittelpunkt steht auch CAU-Professor Marco Liserre: "In Kiel haben wir in den letzten Jahren die Kompetenzen und Netzwerke aufgebaut, um die Forschung an und den Transfer von Energielösungen entscheidend voranzutreiben", sagt der Inhaber des Lehrstuhls für Leistungselektronik. Zunächst soll das flexible Stromnetz im Labor der Technischen Fakultät erprobt werden – anschließend werde ein Stadtquartier definiert, um Kielflex real zu testen.
Dort werden Ladesäulen extrem ausgebaut, ohne aufwendig neue Leitungen zu verlegen. Trotz notwendigen Ausbaus sollen verhältnismäßig wenige Baustellen notwendig werden. Und überhaupt: Das 6,5-Millionen-Euro-Projekt Kielflex soll bis 2020 an bis zu 200 strategisch günstigen Stellen neue Ladepunkte positionieren. Auf eine Mindestzahl wollen sich die Stadtwerke auf Nachfrage allerdings nicht festlegen.
Die Ladestationen der Stadtwerke in Kiel finden Sie hier. Außerdem bieten der Branchenverband BDEW sowie die Bundesnetzagentur Übersichten.

On 22 October Prof. Dr. Liserre received the 2018 Mittelmann Achievement Award in recognition of his attainment in development of power electronic systems for distributed generation and power quality improvement.
The award was given during the banquet of the 2018 IECON in Washington. Congratulations!
Dr. Liserre received the M.Sc. and Ph.D. degrees in Electrical Engineering from the Bari Polytechnic, Italy in 1998 and 2002, respectively. Since then he had been Associate Professor at Bari Polytechnic and from 2012 Professor in reliable power electronics at Aalborg University, Denmark. From 2013 he is Full Professor and holds the Chair of Power Electronics at Kiel University (Germany), where he leads a team of more than 20 researchers with cooperation of 20 companies. The team publishes 60 papers every year, 20 of them are in major journals in the field of power electronics and power systems.
Dr. Liserre’s research interests are in the field of power electronics with specific focus on distributed generation and renewable energy systems, smart grid technologies and reliability. In this field, he has published over 350 technical papers (more than 110 of them in international peer-reviewed journals) and a book on Grid Converters for Photovoltaic and Wind Power Systems, IEEE Press-Wiley, which was translated in Chinese. He is listed in ISI Thomson report “The world’s most influential scientific minds” from 2014.
Dr. Liserre started in 1999 to focus on grid-connected converters addressing power quality and stability problems which became very popular research topics. From 2003, he focussed research on the power converters for photovoltaic and wind turbine systems with particular emphasis on the control issues, publishing an article, which was for several years among the most downloaded from the IEEE Explore.
In 2010, he joined the Center for Reliable Power Electronics in Aalborg, Denmark, as Professor with managerial responsibility, devoting his attention especially to the methods to increase the lifetime of the power converters by controlling their thermal stress.
He was awarded in 2013 with an ERC Consolidator Grant for the project “The Highly Efficient And Reliable smart Transformer (HEART), a new Heart for the Electric Distribution System” and in 2018 with the ERC Proof of Concept Grant U-HEART. The European Excellence Grants are highly reputed grants in Europe. The project was a great success and it did impulse to research on reliability improvements in power electronics through active thermal control, introducing the concept of power routing in modular power converters e.g. uneven share of power among cells to unload devices with higher consumed lifetime. The project did also focus on multi-winding isolated dc/dc converters and it did demonstrate several control capabilities of the Smart Transformer in the electric grid. In this direction a large Project “LV Engine”, led by a large distributed system operator in Scotland will test Smart Transformers in the field to demonstrate the potential of the technology definitively revamping the interest of power electronics company in the field. The Project has also originated a three days Course for PhD Students and Researchers from Industry which is held annually in February.

Prof. Lorenz and Prof. Liserre at the PE: Region Seminar held at CAU, Kiel, Germany
Abstract: Electric machine design paradigms have been dramatically changed by the need to meet the demands for minimizing losses and smooth torque control during driving cycles with widely vary loads and speeds. Simultaneously, new drive control paradigms systematically out-perform industry standard field oriented control (FOC) and simultaneously solve several classical problems with FOC. In addition, the internet of things is opening expansive opportunities for motor drives. This presentation with focus on these disruptive changes in the paradigms for electric machines and electrical drives and explore the opportunities for innovation that these technologies provide.

Abstract: Photovoltaic technology continues to increase its share in the global energy market, with an exceptionally fast growth in the last few decades reaching a cumulative capacity of 227 GW by the end of 2015, with a predicted extra 50GW of new installations for 2016. Residential PV systems are a key element in the success story of PV rooftop installations and large utility scale plants share about 50% of new installations today. ENTSO_E forecasts that by 2025 European power generation will have over 50% renewable, where solar will be expected to have a major role. If we combine the solar increase with even more wind penetration, then this will require a much more flexible system in order to make the best use of renewable energy sources when they are available. By making the best use of cheap renewable electricity when it is available, storage can make the energy system more cost-effective. By adapting to demand and limiting the possibility of peak pricing, storage will also have a balancing effect on prices throughout the day. If solar is combined with storage then this will act as a bridging technology between the electricity, heating and cooling as well as transport sectors. Besides the rapidly developing battery storage capacity, the electrification of the transport sector and the use of electricity for heat purposes allow for an integrated approach of the energy system. This will provide new opportunities for European consumers and businesses, whilst potentially offering a variety of services to grid operators.

Abstract: The fault diagnosis of electrical machines has been the subject of intensive research for several decades. Being able to detect or predict incipient faults before they impair the ability of the machines to function properly is a very welcome feature in industrial environments, where unscheduled downtime can cause production and financial loss.
Electrical machine faults include electrical stator faults, electrical rotor faults, eccentricity, bearing faults. Diagnostic techniques for the detection of such faults in electrical machines are reviewed, and their effectivity is assessed in different operating conditions, including closed-loop inverter-fed operation. Furthermore, the impact of wide-bandgap devices is discussed and prognostic techniques are reviewed, with particular focus on aerospace applications.

Bei den „Power Girls & Power Boys Tagen“ am 18. und 19. Juli in der Technischen Fakultät der Christian-Albrechts-Universität zu Kiel (CAU) war Fingerspitzengefühl gefragt. Schülerinnen und Schüler der fünften und sechsten Klassen aus Kiel und dem Umland stellten ihr Können unter Beweis. Getreu dem Motto „Ausprobieren und Selbermachen“ erhielten die jungen Nachwuchstalente bereits zum achten Mal spannende Einblicke in Technik, Energiegewinnung und Elektronik. Angeleitet wurden sie von wissenschaftlichen Mitarbeiterinnen und Mitarbeitern des Fachbereichs Leistungselektronik.
Die Kinder verkabelten zum Beispiel Handtaschenlampen, bauten solarbetriebene Windenergieanlagen und löteten Herzen aus LED-Leuchten. Unter den 27 Schülerinnen und Schülern war Enrico von der Peter-Ustinov-Schule in Eckernförde einer der schnellsten Tüftler. „In der Schule haben wir sowas noch nicht gemacht“, berichtete der Zwölfjährige. Er sei ebenso wie sein Tischnachbar Felix Lewe (11) von der Gemeinschaftsschule Hassee begeisterter Hobby-Elektrotechniker. Auch bei den Mädchen waren Interesse und Konzentration groß. Der wissenschaftliche Mitarbeiter Stefan Walz freute sich über die rege Teilnahme an dem Projekt und die gute Zusammenarbeit mit den teilnehmenden Schulen: „Die Schülerinnen und Schüler werden dafür anlässlich von Projekttagen extra vom Unterricht freigestellt.“ Die selbstgebauten Geräte konnten die „Power Girls“ und „Power Boys“ am Ende mit nach Hause nehmen. Die Handtaschenlampen sorgen sicher noch weit über die lang ersehnten Sommerferien hinaus für die eine oder andere Erleuchtung.
Die „Power Girls und Power Boys Tage“ werden vom Fachbereich Leistungselektronik veranstaltet und von der Firma Jungheinrich und der Gesellschaft für Energie und Klimaschutz Schleswig-Holstein (EKSH) unterstützt.
