The article describes a new approach to the reliability–exploitation analysis of the critical information and communications technology (ICT) system power supply. A classic approach based on statistical indicators and a new one founded on uncertainty modelling based on the rough set method is presented. The main advantage of the uncertainty modelling approach is the simplification of the calculations and the fact that, unlike statistical analysis, uncertainty modelling does not require complete information on the used data sets. An extensive study of world publications was carried out, proving that this is an entirely innovative approach to solving the problem of reliability and exploitation analysis. Calculations, analyses and syntheses are also exhibited in a specific example. A sample of the ICT system power supply was simulated, and the simulation results are shown. The simulations were prepared by one of the co-authors for the purposes of this article.

“…As it has been mentioned before, it is vital to apply redundant power supplies. For this reason, standby power supplies are introduced next to the main ones [17][18][19][20]. Most frequently, these are generating sets or renewable sources of energy (PV systems, wind turbines).…”

This article describes the issues related to the analysis of the reliability-exploitation of power supply systems in transport telematics devices (PSSs in TTDs). This paper characterizes solutions, which are applied in supply systems, and describes a PSS in a TTD from a main source and a standby one. This enables determining the dependencies denoting the probabilities of the system staying in full ability state, safety threat state, and safety unreliability state. A quality analysis of the PSS in TTD was conducted, and the indicator value of the supply continuity quality was evaluated. This indicator allows the demonstration of continuity quality of power supply (CQoPS) dependency on many quality dimensions, not just reliability. An example demonstrates the calculation of CQoPS factor for both the main and the standby power supply, employing three observations, each influencing the quality. The presented considerations in the field of quality and reliability-exploitation modeling of a PSS can be applied as well in other public utility facilities (including those classified as critical infrastructure). The character of functions performed by critical infrastructure facilities demands an operating continuity of these systems at an appropriate level. The co-first authors of the article once again address the issue of determining CQoPS factor, this time on the basis of modeling using mathematical evidence. TTD is an example in this article, because the presented methods can be used in any kind of system, especially in the power source of critical systems.

“…The application of backup power sources was presented in the publication [6,19]. At the same time, special attention was paid to the emergency power supply systems, such as uninterruptible power supply (UPS), generators, and also environmentally friendly solutions in the form of solar panels or power generators propelled by the force of the wind.…”

The Aspect of Power Supply in Exploitation of Transport Telematics Systems

2019

View full text Add to dashboard Cite

Transport telematics systems operate under various operational conditions. As elements, which are responsible, among others, for the transport process safety, they should maintain their usability. One of the key problems is to ensure the power supply continuity in the transport telematics systems. In order to provide it, relevant power supply systems are used. The state of unfitness of power supply constitutes a failure in the system operation, the result of which can be downtime in operation of the entire transport telematics system or its part. The article carried out a reliability and operation analysis of the power supply system, which consists of three independent energy sources. The relationships, which allow to specify the probabilities of the system’s staying in the distinguished states, were determined.
