This paper presents an FPGA-based (field-programmable gate array) real-time digital simulator for power systems and power electronics applications. The proposed approach integrates the Modified Nodal Analysis (MNA) method, the Fixed Admittance Matrix Nodal Method (FAMNM) and multi-conductor transmission line modeling capabilities. In particular, the MNA is(More)
The paper presents a new method based on the Electromagnetic Time-Reversal (EMTR) for locating faults in power systems. The applicability of the EMTR to electromagnetic transients associated with traveling waves in transmission lines originated by the fault is theoretically demonstrated. A new fault location technique is then proposed and illustrated for a(More)
— 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)
—Installation of small generators in distribution networks has been increased recently due to its various benefits. One of the important issues related to these distributed generators is the effect of system faults on their transient stability. Due to the low inertia constant of the small-scale generators and the slow operation of the distribution networks'(More)
