Non integer order systems are used to model diffusion in conductive parts of electrical machines as they lead to more compact and knowledge models but also to improve their precision. Nevertheless, non integer order models have been established under linear conditions. It is than interesting to study the influence of saturation on such model parameters. In… (More)
This work presents a new approach to model the dynamic behaviour of supercapacitors using half-order systems. The new model is determined in the frequency domain but a Matlab model can be use in simulating the voltage response and energy efficiency e,g. for automotive power.
— This paper aims at proving the application of the fault location method based on the Electromagnetic Time Reversal (EMTR) to multi-terminal HVDC (MTDC) networks. In particular, the paper integrates the EMTR fault location technique with the protection scheme recently proposed within the EU project TWENTIES. Further, in view of the peculiarity of the fast… (More)
The fractional order systems has been used successfully to model in frequency domain the development of induced currents in electric machines, especially in the dampers or massive parts of large synchronous machines. The objective of this work consists in extending the field of application of fractional order models for small signal stability studies of an… (More)
The recent evolution of aircraft power networks makes new design study necessary for solving key issues such as optimal efficiency, reliability, adaptability and performances. Indeed, DC power systems are subject to strong dynamic interactions between the source and the loads. In this paper, the need for a new design method of the power network is… (More)
Improving the braking energy recovery efficiency in light rail systems can reduce their energy consumption. In order to compare and quantify contribution of different technologies with respect to traditional light rail systems, a quasi-static decoupled load flow modelling of a power supply network with AC-DC converters has been developed by the authors. It… (More)
