SCADA systems constitute the nervous systems of Power grids. They rely on SCADA communication links which are dependent upon Telco networks and represent one of the major channels of mutual propagation of disturbances and adverse events between Power grids and Telco networks. Power grids and Telco networks have a heavy impact on daily life and are typically referred as Critical Infrastructures (CIs), since their correct operation is essential for the everyday life of our modern society. Dependent (bi)directional relationships and reciprocal influences among CIs are named (inter)dependencies. CIs interdependencies are largely due to increased CI reliance on Information and Communication Technology (ICT). In this paper, we refer to the Fault Isolation and System Reconfiguration (FISR) service of a SCADA system. FISR detects and isolates faults in Power distribution grid and then reconfigures the grid in order to supply again isolated power customers. In delivering FISR service, SCADA system, Telco network and Power grid are interdependent and act as a whole heterogeneous network. Focusing on FISR service, we compute dependability indicators (such as source-destination connectivity and reliability) and performance indicators (such as packet round trip time, node throughput and packet dynamical paths). Both indicators impact FISR response time which in turn impact the QoS to power grid customers. © 2012 Taylor & Francis Group.
