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

Synchronous machine performance under geomagnetic disturbances
High 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.

Two‐dimensional analytical model for double field excitation synchronous machines
IET Generation, Transmission & Distribution, 2021 This paper examines a two‐dimensional analytical magnetic model presented for double excitation synchronous machines (DESMs). DESMs employ both permanent magnets (PMs) and excitation coils (ECs), and therefore they offer the advantages of permanent ...
