Evaluation of Time-Critical Communications for IEC 61850-Substation Network Architecture

Ahmed Altaher, Jean-Marc Thiriet
2015 arXiv   pre-print
Present-day developments, in electrical power transmission and distribution, require considerations of the status quo. In other meaning, international regulations enforce increasing of reliability and reducing of environment impact, correspondingly they motivate developing of dependable systems. Power grids especially intelligent (smart grids) ones become industrial solutions that follow standardized development. The International standardization, in the field of power transmission and

The rise of dedicated standards for SAS (Substation Automation Systems) communications, such as the leading International Electro-technical Commission standard IEC 61850, enforces modern technological trends in this field. Within this standard, a constraint of low ETE (End-to-End) latency should be respected, and time-critical status transmission must be achieved. This experimental study emphasis on IEC 61850 SAS communication standard, e.g. IEC 61850 GOOSE (Generic Object Oriented Substation Events), to implement an investigational method to determine the protection communication delay. This method observes GOOSE behaviour by adopting monitoring and analysis capabilities. It is observed by using network test equipment, i.e. SPAN (Switch Port Analyser) and TAP (Test Access Point) devices, with on-the-shelf available hardware and software solutions.

A Framework for the Reliability Evaluation of Networked Control Systems

Rony Ghostine, Jean-Marc Thiriet, Jean-François Aubry, Michel Robert
2008 IFAC Proceedings Volumes  
this paper presents a framework to enable the analysis of the influence of the transmission faults on the reliability of a networked control system (NCS). The approach is composed of two parts: a modelling part in which all the basic components of a networked control system are modelled and a simulation part in which simulation is done on the models to evaluate the reliability. Due to external perturbations transmission faults may occur on the medium decreasing network quality of service and

The results show that our framework is an effective way for the reliability evaluation of networked control systems (Copyright IFAC 2008).

Variable delays and message losses: Influence on the reliability of a control loop

Rony Ghostine, Jean-Marc Thiriet, Jean-François Aubry
2011 Reliability Engineering & System Safety  
Today, new technologies (distributed systems, networks communication) are more and more integrated for applications needing to fit real-time and critical constraints. It means that we require more and more to integrate these new technology-based components in systems or sub-systems dedicated to safety or dealing with a high level of criticality. Control systems are generally evaluated as a function of required performances (overshoot, rising time, response time) under the condition to respect a
more » ... stability condition. Reliability evaluation of such systems is not trivial, because generally classical methods do not take into account time and dynamic properties which are the bases of control systems. The methodology proposed in this paper deals with an approach for the dependability evaluation of control systems, based on Monte-Carlo simulation, giving a contribution to the integration of automatic control and dependability constraints.

Glucose administration before exercise modulates catecholaminergic responses in glycogen-depleted subjects. J. Appl. Physiol. 82(1): 248-256, 1997.-In glycogen-depleted subjects (GD) a nonlinear increase in epinephrine (Epi) and norepinephrine (NE) parallels blood lactate (La) during graded exercise. The effect of glucose (Glc) supplementation and route of administration on these relationships was studied in 26 GD athletes who were randomly assigned to receive 1.3 g/kg Glc by slow intravenous

Performance and La were similar among the three groups in normal glycogen (NG) or GD conditions. However, slightly improved performances were observed in GD compared with NG and were associated with a shift to the right in La curves. Blood Glc concentrations were higher in IV and PO before exercise, but they rapidly decreased to lowest levels in IV, gradually decreased over time in PO, and remained stable in Asp or NG. Insulin concentrations were highest in IV and lowest in Asp and NG at onset of exercise, rapidly decreasing in IV and PO although remaining at higher levels than in Asp or NG. In contrast, higher serum levels of free fatty acids were measured during exercise in Asp with no significant differences in glucagon or glycerol among the three groups. Free and sulfated NE increases were smaller in IV than in PO and Asp on exhaustion. In contrast, free and conjugated Epi were most increased in IV, with smallest increases in Asp. Dopamine levels were most increased in IV at exhaustion. We conclude that the changes of Epi and NE concentrations, associated with the activation of glucoregulatory mechanisms, including hyperinsulinemia, display different magnitude and time courses during exercise in GD subjects who receive oral vs. intravenous load of Glc before exercise. We speculate that the magnitude of insulin surge after acutely increased Glc before exercise in GD subjects may exert dissociative effects on adrenal-dependent glycogenolysis and on sympathetic responses.

Zeashan Hameed Khan, Denis Genon Catalot, Jean Marc Thiriet
2009 2009 Fifth International Conference on Wireless and Mobile Communications  
This paper describes a hierarchical wireless network architecture for real time remote coordination and monitoring in distributed applications. The problem of defining a communication architecture keeping in view the constraints imposed by control and monitoring tasks requires a co-design approach. The present framework takes into account the available infrastructure to satisfy the requirements of end to end delay and quality of service for time critical applications communicating over network.

Selection for non-specific adhesion is a driver of FimH evolution increasing Escherichia coli biofilm capacity [article]

Mari YOSHIDA, Stanislas THIRIET-RUPERT, Leonie MAYER, Christophe BELOIN, Jean-Marc GHIGO
2021 bioRxiv   pre-print
Bacterial interactions with surfaces rely on the coordinated expression and interplay of surface exposed adhesion factors. However, how bacteria dynamically modulate their vast repertoire of adhesins to achieve surface colonization is not yet well-understood. We used experimental evolution and positive selection for improved adhesion to investigate how an initially poorly adherent Escherichia coli strain increased its adhesion capacities to abiotic surfaces. We showed that all identified

While most of these fimH mutants showed reduced mannose-binding ability, they all displayed enhanced binding to abiotic surfaces, indicating a trade-off between FimH-mediated specific and non-specific adhesion properties. Several of the identified mutations were already reported in FimH lectin domain of pathogenic and environmental E. coli, suggesting that, beyond patho-adaptation, FimH microevolution favoring non-specific surface adhesion could constitute a selective advantage for natural E. coli isolates. Consistently, although E. coli deleted for the fim operon still evolves an increased adhesion capacity, mutants selected in the ∆fim background are outcompeted by fimH mutants revealing clonal interference for adhesion. Our study therefore provides insights into the plasticity of E. coli adhesion potential and shows that evolution of type 1 fimbriae is a major driver of the adaptation of natural E. coli to colonization.
