High-voltage switchgear stations consist of numerous components, actuators, censors, and a quite complex distributed computing system. On different hierarchical levels, there are several types of embedded computing systems: The PISAs (process interface for sensors and actuators), VME racks for control and protection, bus administrators, and star coupler modules. A failure in the power delivery leads to enormous costs. Minimizing the down-time-related costs must be combined with the objectives to keep maintenance costs down and not to exaggerate the initial investment costs. This article presents a general approach to this combined optimization problem applied successfully to the case of high-voltage switchgear stations.
