Transition Theory in Operation of Electrical Installations

In the operation of electrical installations, risk assessment evaluates hazards and conflicts. A kinematics analogy for analyzing the risk of “collisions” offers a new approach for operational procedures and allows the introduction of a “transition” theory for intersections. The architecture of electrical installations can be designed in increasing complexity related to its exigencies, taking actions on multiple sources and on the configuration. Analogies between the operation of highway intersections of multiple traffic lanes and the operation of nodes of electrical power systems are proposed as offering an equivalent well-known way for examining constraints in the transitions, for facilitating the understanding of the mathematical description, and for suggesting new approaches and new methodologies for solutions. Automatic transfer switches also assisted by engine generators and UPSs are available as basic equipment to support transitions. This paper describes the special configuration of the node “double two,” constituted by two automatic transfer switches connectible in parallel.
