3.8.3 System Network Reliability Implementation


To add reliability and optimize the SCADA system network
topology layout as mentioned previously,two methodswereused:Dual
Linksthat areused as a backup line, and Redundant Paths, in which the
following points weretaken into consideration:



  1. Each station has at least two links to other stations.

  2. Links lengths depend on cables lengths calculated previously.

  3. Building tree-ring network topology.
    Figure 3. 11 illustrates reliability added in order to build a reliable
    and robust topology, where white dots links represent dual links, and red
    links represent redundant cables.
