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 ...

Observation and Distinction. Representing Information in Infinite Games [PDF]

open access: yes, 2020
We compare two approaches for modelling imperfect information in infinite games by using finite-state automata. The first, more standard approach views information as the result of an observation process driven by a sequential Mealy machine. In contrast,

Influence of frequency on the synchronous electrical machine parameters

open access: yesVestnik MGTU, 2018
The current and moment of resistance to rotation of the inductive synchronous electric machine under inductive load have been considered. For a synchronous machine with an inductive load, Theorem 1 is valid: the current amplitude in the inductive load of

Position estimation delays in signal injection-based sensorless PMSM drives [PDF]

open access: yes, 2012
The causes of position estimation delays and their effects on the sensorless control of permanent magnet synchronous motor drives are investigated. The position of a permanent magnet synchronous machine is estimated via the injection of high frequency ...
