Real time recovery of fault tolerant processing elements

15th DASC. AIAA/IEEE Digital Avionics Systems Conference, 1997
A critical problem in the design of ultra-reliable fault tolerant systems is that of how to bring a redundant member back on-line, after a transient fault, without degrading critical real-time functions. Recovery from transients is imperative to maintain necessary system reliability in the face of transient errors which have been estimated to occur at ...

Early Warning and Inhibition of HVDC Subsequent Commutation Failure During Recovery Process Under Grid Fault

IEEE Transactions on Power Delivery, 2021
Initiation of ac fault may lead to the commutation failure, and the high-voltage direct current (HVDC) system is still confronted with the risk of subsequent commutation failure (SCF) during recovery process prior to the fault clearance. In this paper, the mechanism of subsequent commutation failure is investigated through the analysis of controller ...

Operators' Monitoring Patterns and Fault Recovery in the Supervisory Control of a Semi-Automatic Process

Proceedings of the Human Factors Society Annual Meeting, 1992
Although technological innovations have changed the role of operators from active participants to supervisors of semiautomatic processes, an understanding of the cognitive demands of supervisory control has not kept pace. In particular, little is known about when, and how well, operators might intervene and switch control from automatic to manual ...

Fault diagnosis and recovery in MEMS inertial navigation system using information filters and Gaussian processes

22nd Mediterranean Conference on Control and Automation, 2014
An integrated navigation system (INS) on a vehicle platform such as a quadrotor UAV is an example of a multisensor system, wherein data streams coming from different sensors are combined to bring about improved situational awareness. This paper examines the implementation of two related approaches to distributed estimation and fault diagnosis in a ...

Development and Application of Response Curve Library for Asymmetric Fault Recovery Process of Intermittent Power Generation Equipment

2020 12th IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2020
Facing the challenges of global energy resources, environmental pollution and so on, Large-scale development and utilization of clean energy is imperative. Clean energy has a strong intermittent characteristics, The simulation analysis of the faults and the recovery process of this kind of equipment also need to be carried out in large numbers.

Analysis of Fault Recovery Process in Distribution Networks with the Integration of Soft Open Point

After a fault occurs in the distribution network, the real-time balance between power supply and load demand must be met. Load can be restored through upper sources and the nearby power supply of distributed generators. Therefore, it is necessary to construct the power transmission path between each node, namely transmission matrix.

A Battery Energy Storage Based Methodology to Accelerate Post-Fault Voltage and Frequency Recovery Process in Microgrid

2018 IEEE International WIE Conference on Electrical and Computer Engineering (WIECON-ECE), 2018
Due to high penetration of renewable energy into the electrical power system in recent years it has become a challenge to make the smart grid robust in terms of voltage deviation and frequency fluctuation. To mitigate these issues, proper selection of energy storage system (ESS) is becoming an essential part of future grid design.
