A structured collection of tools for engineering resilience and a research approach to improve the resilience of a power grid are described in this paper. The collection is organized by a two-dimensional array formed from typologies of power grid components and business processes. These two dimensions provide physical and operational outlooks, respectively, for a power grid. The approach for resilience research is based on building a simulation model of a power grid which utilizes a resilience assessment equation to assess baseline resilience to a hazards’ profile, then iteratively selects a subset of tools from the collection, and introduces these as interventions in the power grid simulation model. Calculating the difference in resilience associated with each subset supports multicriteria decision-making to find the most convenient subset of interventions for a power grid and hazards’ profile. Resilience is an emergent quality of a power grid system, and therefore resilience research and interventions must be system-driven. This paper outlines further research required prior to the practical application of this approach.

“…In recent years, with the increasing demands on electric power supply, it is very important to enhance the safety of power transmission line. Hence, considerable efforts have been made by different researchers to investigate the behaviour of power transmission towers under different loading and environmental conditions [1][2][3][4][5][6]. In some countries, such as China, many power transmission towers have to pass across coal mining areas.…”

In this paper, two 1:2 scaled substructure models for a typical 110 kV transmission tower were designed and fabricated. The scaled tower substructure models were tested subjected to the stretching movements of horizontal ground surface under different wind load conditions. The wind speeds were assumed to be 15 m/s and 30 m/s, respectively in this study. The deformations of the tested tower models and the stresses and strains within the different members of the tower were fully measured. A large amount of the comprehensive test data was generated. Also a FE model using ANSYS was developed and validated by the test data. The research indicated that wind load has a significant unfavourable influence on the resistance of the transmission tower subjected to the ground surface deformation. Also the research showed that it is possible to use the FE model for the analysis and design of power transmission towers under ground surface movements.

In this paper, a 1:5 scaled tower model for a typical 220 kV single-circuit power transmission tower with hybrid slab foundation has been designed and tested. The scaled tower model was tested under the movement of horizontal ground surface stretching with normal working loading conditions. One of the main objectives of this research is to investigate the stability of the power transmission tower subjected to horizontal ground movement by using hybrid slab foundation. The deformations of the tested tower model and stresses and strains within the different structural members of the tower and the reinforced concrete slab of the foundation have been fully measured. A large mount comprehensive test data has been generated. The research clearly indicated that compared to the isolated tower leg's foundation the proposed hybrid slab foundation has very good resistance, in terms of truss members' deformations and stresses, to the ground movement.
