Integral Sensor Fault Detection and Isolation for Railway Traction Drive
(MDPI AG, 2018)
Due to the increasing importance of reliability and availability of electric traction drives in Railway applications, early detection of faults has become an important key for Railway traction drive manufacturers. Sensor ...
DC-Link Voltage and Catenary Current Sensors Fault Reconstruction for Railway Traction Drives
(MDPI AG, 2018)
Due to the importance of sensors in control strategy and safety, early detection of faults in sensors has become a key point to improve the availability of railway traction drives. The presented sensor fault reconstruction ...
Hardware-in-the-loop performance analysis of a railway traction system under sensor faults
(IET, 2019)
Fault mode and effects analysis (FMEA) has been used during decades for analysing the effects of faults in different applications. Initially, FMEA based on risk priority numbers provided information about the effects in ...
Model driven Hardware-in-the-Loop Fault analysis of railway traction systems
(IEEE, 2017)
Classical Dependability Analysis techniques, such as Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis, have been used during the last decades to demonstrate the reliability, availability, maintainability ...
Automatic detection test of current sensor faults for induction motor drives at standstill
(IEEE, 2016)
This paper proposes an automatic detection test of gain faults in current sensors. An offline test is applied when the machine is not operating. The designed test operates at standstill without being necessary to disconnect ...
DC-link sensor Fault Detection and isolation for railway traction electric drives
(IEEE, 2017)
This article presents the design and the implementation of a fault detection and isolation strategy for sensors in variable speed drives. Electric drives use several current and voltage sensors for control and protection. ...
