Reliability of the information transmission system and the information processing system has a great effect on the reliability of the centralized supervisory control system in power systems. The reliability of the centralized supervisory control system in terms of the expected information loss and the mean time between system failures (MTSF) has been discussed previously. Here a reliability design method of the centralized supervisory control system using these two reliability indices is proposed considering the following two problems: assigning redundancy so as to minimize the expected information loss subject to cost constraints; and assigning redundancy so as to minimize the cost subject to MTSF constraints. The two problems are formulated to a 0 to 1 type integer linear program. Numerical examples are given. It is shown that the number of constraints and the number of variables can be reduced greatly by limiting the extent of redundancy to duplication. The results obtained by the two algorithms coincide with each other.
