  • Availability Comparison of Various Power Substation Automation Architectures
    IEEE Transactions on Power Delivery, 2013
    Co-Authors: Hamze Hajian-hoseinabadi
    Abstract:

    This study aims at quantitatively assessing the availability indices of various Substation Automation systems. In order to illustrate the proposed technique, first, nine types of Substation Automation architectures are reviewed. The reliability block diagrams of various Substation Automation architectures are then developed. Subsequently, comparative studies are performed to demonstrate the most reliable architectures in comparison with the others. The results obtained by the proposed approach show the impact of repair on availability indices of the Automation system. Finally, different sensitivity analyses are conducted for all architectures, where the impact of varying availability of all components on reliability indices of the Automation system is illustrated.

  • Reliability and component importance analysis of Substation Automation systems
    International Journal of Electrical Power & Energy Systems, 2013
    Co-Authors: Hamze Hajian-hoseinabadi
    Abstract:

    Abstract This paper aims to present a comprehensive technique to quantitatively assess the reliability of Substation Automation systems. The technique is based on the tie-sets methodology. In order to demonstrate the application of the proposed technique, a variety of Substation Automation architectures is first introduced. The associated reliability block diagrams as well as the exact system reliability are then given. The impacts and the degree of importance of various components on the reliability of Substation Automation systems are presented. Two suitable measures of importance are selected. The first is the Birnbaum’s measure used to determine the bottleneck of the system reliability. The second measure uses criticality importance to diagnose failures and generating repair or inspection checklists.

  • Efficient Planning of Substation Automation System Cables
    Integration of AI and OR Techniques in Constraint Programming for Combinatorial Optimization Problems, 2011
    Co-Authors: Thanikesavan Sivanthi, Jan Poland
    Abstract:

    The manual selection and assignment of appropriate cables to the interconnections between the devices of a Substation Automation system is a major cost factor in Substation Automation system design. This paper discusses about the modeling of the Substation Automation system cable planning as an integer linear optimization problem to generate an efficient cable plan for Substation Automation systems.
