Presenter: Panos Kotsampopoulos, National Technical University of Athens (NTUA)
Abstract: PHIL and CHIL simulation is proving to be an efficient tool for research, testing and education. Best experiences of using HIL simulation at the National Technical University of Athens (NTUA) are presented focusing on power electronic converters and smart grid controllers. First, the proposed procedure, stages and topologies for the testing of power electronic converters are shown, related to battery inverter development and testing, FACTS testing, microgrid control and interactions between DER and OLTC. The second part deals with the HIL testing of smart grid controllers, including the testing of a coordinated voltage controller in a combined CHIL and PHIL setup, the adaptive protection testing via HIL simulation and the testing of a distributed control scheme based on Multi-Agent Systems. The last part of the presentation explains the benefits of using PHIL simulation as an advanced method for hands-on and experiential laboratory education.

Presenter: Robert Dimitrovski, Friedrich-Alexander University Erlangen-Nürnberg (FAU)
Abstract: All turbine-shaft models used in EMT-type simulation software present an implementation of the spring-mass damper system. In most cases, the spring-mass based model of the turbine-generator shaft is sufficiently accurate to predict the torsional frequencies with a high degree of precision for the significant modes. The parameters of the spring-mass system are the moments of inertia, the spring constants, and the damping of the masses. While the first two parameters are generally well known, the prediction of the damping is very difficult, and it is often found to differ from the measured values by a factor of two to five. On the other hand, the measured damping provided by the manufacturers is often in modal form, which cannot be used in the spring-mass model in a physically meaningful manner.
For better correlation between field measurements and simulation results in studies related to the investigation of torsional interactions between power electronic devices and conventional turbine-generator units, the existing multi-mass model in RSCAD (CBuilder) is further developed to allow the insertion of modal damping. The accuracy of the enhanced model is verified against a benchmark model in PSS NETOMAC. The developed model can be used for HIL testing of various control systems in the context of subsynchronous or supersynchronous torsional interactions.
Bio: Robert Dimitrovski (M’15) received the Dipl.-Ing. degree from Ss. Cyril and Methodius University, Skopje, Macedonia in 2009 and the M.Sc. degree in electrical power engineering from Brandenburg University of Technology, Cottbus, Germany, in 2011.
