Power systems are now controlled by a wide-area monitoring and control system (WAMS), which continuously measures and registers status vector values and is synchronised by signals from the uniform time system. The local information network is an important component of this system, and its dependability is crucial to the successful operation of WAMS. The said dependability can be evaluated by breaking it down into components. These are hardware or technical reliability related to failure (destruction) of transmission channel elements or communication line integrity, traffic reliability determined by time loss or data distortion without failure of a transmission channel element, software reliability related to errors in the development of exchange execution programmes, and resilience against an external deliberate impact on the transmitted information. This research examines the first three dependability components of an information network, calculating the total value and estimating the contribution of each component. The final component (resistance to an external deliberate action) has been discussed in a large number of studies, hence it is not addressed in this paper.
