Fiber - Optic Loop Network With Active Nodes For An Electrical Power Plant

subject

description

This paper presents a fiber optic loop network for a measurement and control system of an electric power plant. The network consists of the central computer terminal, the set of specially distributed digital FO links and local station installed at the important power facilities. The well-known FO link advantages contribUte to high reliability and safety of work of the system. The operation of the loop network, treated as an autonomous one, is controlled by a microcomputer system. Transmission protocols and the cooperation with the local station are also described. The proposed loop network model is illustrated with an example of the laboratory - scale system.
