    KoMoM entwickelt Konzepte zur sicheren Inbetriebnahme, erweiterten Nutzung und umfassenden Überwachung modularer Hochspannungs-Mehrpunktstromrichter z.B. für ein Multiterminal-DC-Transportnetz. Dazu werden innovative Mess-, Analyse- und Regelungsverfahren mit moderner Rechnertechnik, leistungsfähigen programmierbaren Logikbausteinen und neuesten Zeitreihenmodellen verknüpft. Messungen unter Einbeziehung eines vorhandenen, derzeit einzigartigen, Multiterminal-DC-Transportnetz-Versuchsstandes dienen der Verifikation. Der Versuchsstand besteht aus vier Mehrpunktstromrichtern auf Basis von Vollbrückenmodulen in den Stromrichterzweigen und beherrscht DC-Kurzschlüsse im geregelten Betrieb. Er entstammt einem Projekt mit der Firma Amprion und emuliert die erste im Netzentwicklungsplan vorgesehene Hochspannungs-Gleichstrom-Übertragungsstrecke (HGÜ) „Ultranet“ (Amprion, TransnetBW).

    Kurzschlussbeherrschung und -abschaltung im geregelten Betrieb erfordern hochgenaue DC-fähige Strommesstechnik auf Höchstspannungsniveau. Mess- und Regelungskonzepte hierfür werden im Projekt erarbeitet bzw. adaptiert.

    Dynamische Wirk- und Blindleistungsstellung sowie Oberschwingungskompensation sind höchst relevante Netzdienstleistungen. Realisierungskonzepte, Möglichkeiten und Grenzen werden erarbeitet und erforscht. Auch die Interaktion von Stromrichtern und deren Regelung ist für stabilen Betrieb entscheidend. Das Projekt erarbeitet Beschreibungen für Stromrichter in unterschiedlichen Spannungsebenen, kombiniert diese mit einer geeigneten stromrichternahen Regelung und einer Anlagencharakteristik und leitet daraus Möglichkeiten und Grenzen des Zusammenspiels von Stromrichtern im Netz ab.

    Die komplexe Stromrichtertopologie und die herausfordernde Mess- und Regelungstechnik stellen höchste Anforderungen an Inbetriebnahmekonzepte – heutige Methoden sind nicht wirtschaftlich und risikoreich. Erweiterte, spezielle Hardware-In-The-Loop (HIL)-Verfahren zur Vorabverifikation werden erarbeitet.

    Die Komplexität drückt sich auch in einer Vielzahl von Messgrößen aus: An realen Anlagen fallen mehrere tausend Messdaten mehrere hundert Mal pro Sekunde an und sind zu bewerten. Dieses „Big Data“-Problem wird mit Blick auf Zustandsmonitoring und Ereignisarchivierung durch eine neuartige Ausrichtung aktueller Methoden der Zeitreihenanalyse angegangen.

    Projektabschluss: 09/2020

    WindOptTool- Development of an expert system for the analysis, the assessment and the optimization of the grid integration of wind-power plants



    Windopttool Förderlogos Klein

    How can wind farms be developed optimally despite the enormous technical complexity? The institute EneSys of the Ruhr-University of Bochum (RUB) and the company Avasition GmbH are dealing with this question within the joint research project "WindOptTool".

    As one major part of the German "Energiewende", the importance of the usage of wind power is increasing continuously. Wind-power plants with higher power rating and larger wind farms are realized to achieve a sustainable power supply. In this scope, an adequate and smart asset design and planning is indispensable. Due to the rising grid-integration requirements and diverse other impacts like e.g. the stochastic wind appearance and the interactions between wind-power plants, adequate design and planning is more and more challenging.

    This is where the project "WindOptTool" comes into play. An expert system is designed in which the knowhow for all relevant components of wind farms is bundled. Based on the features of the expert system, possible critical interactions of subsystems can be identified in an early project phase. Optimization suggestions concerning the design and dimensioning of the different components can cope the identified problems. Thus, the planned and designed assets are getting more efficient, more reliant and, with this, more economically viable.
    Within the joint research project, the institute for Power Systems Technology and Power Mechatronics of the RUB and the company Avasition GmbH are participating partners. The project kick-off took place at the RUB under the direction of the project coordinator Prof. Dr.-Ing. Constantinos Sourkounis on Dezember the 19th 2016. The project volume is greater than one million euro and the project duration is three years.

    The joint research project is funded by the European Union and the federal state of North Rhine-Westphalia within the scope of the European Regional Development Fund (ERDF) 2014-2020 "Investing in our Future".

    Membership in the competence center for hydraulic machinery of the Ruhr-University Bochum


    The Institute for Energy Systems and Power Mechatronics is a member of the competence center hydraulic machinery, a research network of the Ruhr-University Bochum. As part of this membership, EneSys is doing research with the drive system and the control of hydraulic machinery.

    The operation of pumps is characterized by sophisticated thermal and chemical environments. This concerns the pumped medium because this can have a temperature above 100 ° C and aggressive chemical substances, on the other hand, the environmental conditions of the installation are often out of spec. Nevertheless, a reliable and efficient operation must be guaranteed. In addition to the efficiency further boundary conditions have to be considered as a low-noise operation and extreme demands on the part of the supply mains. Among these, dynamically changing, conditions the design and interpretation of an efficient and cost-effective drive unit a technical challenge.

    The general research in the field of drive technology for pump is driven by the optimization of the subsystems in the static nominal operating ranges. The optimization refers not only to increase efficiency but reflects the tension between efficiency, reliability and cost, which includes aspects such as manufacturability, reduction of required sensors etc..

    As part of the KHS an integrated research approach is followed. The optimization and increased efficiency of the overall system is paramount. These subsystems are optimized to account for interactions with each other in the overall system and respect to the overall objectives. The overall objectives are optimized.
    In the project plan optimization potential in the area of the drive system are explored. They are over the entire operating range, in particular also the partial load operation is identified. Approaches to achieve a cost-optimal utilization of these potentials in compliance with the above requirements, yet safe operation under unsafe conditions.

    High-precision current sensor with a novel modulation method

    The focus of this project is to develop a highly accurate current sensor with a novel modulation method. The ASIC 'IHM-A-1500'will be used as the measurement unit from the Company Isabellenhütte. This chip uses the measured voltage drop over a shunt for the current measurement. The resolution of the measured current is 16 bits. This 16-bit value is coded by means of a modulation unit into a special PWM signal, where the pulse width and the period are variable. The method for encoding the signal is called as F-PWM. Because of the simple digitization of the measured signal, it can be demodulated with each microcontroller-based measurement unit.

    Das Pro­jekt hat das Ziel, In­be­trieb­nah­men von SPS-ge­steu­er­ten In­dus­trie­an­la­gen zu op­ti­mie­ren. Im Rah­men des Pro­jek­tes wird eine Soft­ware zur Hard­ware-in-the-lo­op-Prü­fung von SPS-Steue­rungs­sys­te­men ent­wi­ckelt. Die zu steu­ern­de An­la­ge wird in einer Si­mu­la­ti­ons­um­ge­bung nach­ge­bil­det und mit dem zu prü­fen­den SPS-Sys­tem ver­bun­den. So kann das SPS-Sys­tem auf kor­rek­te Funk­tio­na­li­tät ge­prüft wer­den schon bevor die An­la­ge fer­tig ge­stellt ist. Es kön­nen ge­zielt Si­cher­heits­funk­tio­nen ge­tes­tet und eva­lu­iert wer­den, die sonst eine Schä­di­gung oder Zer­stö­rung der An­la­ge zur Folge hät­ten. Dies spart Zeit und Kos­ten für die In­be­trieb­nah­me, au­ßer­dem ist die Feh­ler­su­che und –be­he­bung leicht durch­zu­füh­ren. Das Si­mu­la­ti­ons­sys­tem ist frei kon­fi­gu­rier­bar und kann so an an­de­re An­la­gen­ty­pen an­ge­passt wer­den.
