Application of optical fiber connections in low voltage distribution network management systems

The paper discusses technological solutions that are applied to organize communication among technical devices in an electrical substation. Design and operation of presently used supervision and control systems are based on various communication solutions. Ever growing standards concerning the required quantity of data and their transmission rate induce a search for new solutions. The paper presents new concepts of data exchange standards based on optical fiber networks and an equipment that can be applied to develop SCADA systems using that technology.
An example of a physical communication model has been used to present a configuration of devices that form a frame of the network and remote control elements that use it.
