A Power Hardware in the Loop (FHIL) platform implementation for performing real time simulations of electric systems is proposed. The test bench consists of a FSS'®E real time power flow calculation in combination with a controlled grid emulator. Experimental results are presented to demonstrate the performance of the platform.
The simulation of transmission and distribution grids comes with a trade-off between the number of modeled components and the modeling depth on the one hand and the simulation speed on the other hand. An example system of a grid converter of a 2 MW full scale converter system is used to show a step-by-step model order reduction. Starting from a detailed switched model the order reduction is shown...
In present work is carried out modelling of single transistor parallel ZVS DC-DC converter. Main advantage of power circuit is direct work in steady mode. Thus, that allows avoiding a starting procedure and guarantees reliable operation in significant major change in load occur. The model is realised with Matlab. Computer simulations and experiments in lab model are performed by which the model is...
Some modelling methods and associated tools are presented in this paper to efficiently and accurately simulate the electromagnetic behaviour of power electronic structures. Moreover, as engineers have to face new challenges, the synergy between simulation tools is illustrated as a possible solution for addressing this "multiphysic" topic. The article is also pictured of several application...
The paper presents the topology and functioning of the model-based laboratory system to study the power electronic converters structure and execution and to evaluate their different duty modes of operation. Detailed description of the models of ac/dc, dc/ac, ac/ac and dc/dc virtual power converters and their auxiliary circuits are given.

A free SPICE version allowing general circuit simulation is used teaching power electronics. There is no lock on the circuit size, stabile and user friendly operation is experienced. A collection of transformer, converter and drive system models are implemented to investigate the usability of the programme in high power electronics.
This paper presents a comprehensive assessment of small-signal stability for a ldquomore-electricrdquo aircraft power system consisting of a synchronous variable-frequency generator which supplies several power electronic controlled loads via an 18-pulse autotransformer rectifier unit (ATRU) for AC-DC conversion. Functional models for key power system components and loads are derived. Numerical tools...
The problem of electric drive design concerns the multi-criteria non-linear problems having a number of solutions. In daily practice the search of optimum solution bases a great deal on the designer intuition and experience. Therefore, multiple obtained results have a low degree of equipment use, unwarranted complexity, or excessive cost. Proposed approach is devoted to implementation of the novel...
