This paper deals with a new scheme for coupling phasor-mode and electromagnetic transients simulations. In each simulation, an iteratively updated linear equivalent is used to represent the effect of the subsystem treated by the other simulation. Time interpolation and phasor extraction methods adapted to this scheme are presented and compared to existing methods. Finally, simulation results obtained with a 74-bus test system are reported.

Hybrid simulations combining phasor-mode and electromagnetic transients models aim at taking advantage of computational speed of the former and accuracy of the latter. For simulation accuracy, a relaxation process is used, which consists of iterating between both models. The convergence properties of this relaxation process are investigated. The speed of convergence is assessed when the variables exchanged at the interface between both models are respectively pure voltage/current sources, Norton/Thévenin equivalents, or a combination of them. Iteratively updated Norton/Thévenin equivalents are shown to drastically reduce the number of relaxation iterations. [less ▲]

Abstract--- A new multi-rate technique is proposed to combine fundamental-frequency simulation (typical of stability studies) with electromagnetic transients simulation. The objective of this hybrid approach is to obtain more accurate simulations than with the fundamental-frequency approximation, while saving computing time by applying the detailed model to a subsystem only, in some neighbourhood of the disturbance. It also allows to remove some limitations of fundamental-frequency simulation, such as the difficulty of simulating unbalanced faults. A relaxation technique is used to iterate between both models with simple interfacing. Preliminary results obtained with a 74-bus test system are presented, together with a comparison with full electromagnetic transients simulation. [less ▲]

Power Electronics education at the University of Liège exhibits a particular feature, in that a person from industry is directly involved in the teaching of the introductory Power Electronics course since academic year 2007-2008. Together with him, we teach this subject making use of a project-oriented method. After two years of this experience, it is now of great interest to analyze the main benefits of this method for the students, the teaching team at the University and the company involved in the teaching process. In this paper we present through an example the method that is being used. We mention some interesting technical problems encountered by the students during their project work. We also present the evolution of the method from the first year of application in 2007-2008 to the forthcoming third year in 2009-2010. [less ▲]

For the first time during year 2007-2008, a complete design of a DC/DC converter, based on specifications only, was asked to the students following the basic Power Electronics course at University of Liège. This very realistic pedagogical way of teaching helped the students to be autonomous, to learn project and team work. [less ▲]
