An Architecture-Based Framework for Reliability Analysis of ICT for Power Systems
2011 (English)In: Power and Energy Society General Meeting, 2011 IEEE, 2011Conference paper (Refereed)
This paper presents an architecture based framework for reliability analysis of ICT systems for power system protection, monitoring and control. The analysis framework applies Probabilistic Relational Models (PRMs) - providing a combination of entity-relationship diagrams together with a probabilistic analysis engine of Bayesian networks. Moreover, the framework allows modeling and analysis of the relations between the ICT and the power system, including both physical and logical relations. Three architectural scenarios are presented onto which the analysis framework is applied. By using component failure rates gathered from various sources each scenario is analyzed based on the probability of successful operation. Calculations are preformed using Bayesian networks and contrasted with the application of Reliability Block Diagrams. The outcome verifies the successful use of PRMs for reliability analysis of ICT systems for power system protection, monitoring and control architecture.
