Turn-to-turn fault protection technique for synchronous machines without additional voltage transformers [PDF]

open access: yes, 2017
This paper presents a novel protection technique for the detection of inter-turn faults in synchronous machines. It is based on the calculation of voltage in the stator windings from the usual phases and neutral voltage, typically available in ...

Start-up of virtual synchronous machine: methods and experimental comparison [PDF]

open access: yes, 2018
A modern grid is smarter mainly in the advance in information and communication technologies, while the power processing mechanism does not make a big difference.

Modular nonblocking verification using conflict equivalence [PDF]

open access: yes, 2006
This paper proposes a modular approach to verifying whether a large discrete event system is nonconflicting. The new approach avoids computing the synchronous product of a large set of finite-state machines.

Synchronous machine performance under geomagnetic disturbances

open access: yesHigh Voltage, 2021
Geomagnetic disturbances (GMDs) are known to disturb power system equipment performance. The danger is associated with geomagnetically induced currents (GICs) occurring at the Earth's surface during GMD.

Polychronous Interpretation of Synoptic, a Domain Specific Modeling Language for Embedded Flight-Software [PDF]

open access: yes, 2009
The SPaCIFY project, which aims at bringing advances in MDE to the satellite flight software industry, advocates a top-down approach built on a domain-specific modeling language named Synoptic.

Investigation of the stator inductances of the expanded Park model and an approach on parameter identification using the evolution strategy

open access: yesArchives of Electrical Engineering, 2016
Commonly, the Park model is used to calculate transients or steady-state operations of synchronous machines. The expanded Park theory derives the Park equations from the phase-domain model of the synchronous machine by the use of transformations. Thereby,
