An electrical grid is a large, interconnected network for delivering electricity from suppliers to consumers. It consists of three main components: power generating plants, transmission lines, and transformers that reduce voltage for final delivery. It is crucial to an electrical power grid to constantly monitor, enhance and optimize Energy Management in a secure and timely manner. Selecting the right Communications solution to use in the Energy Management process is a key factor in successfully running any electrical grid.
Tadiran solutions for electric power grids comprise a fault tolerant and resilient real-time communications systems network for power dispatchers. This network allows dispatchers to communicate with peers at the district, regional, and substation levels. The mission-critical communications network is built with multiple levels of redundancy and network flow algorithms to insure that all calls get to their destination. In extreme load conditions in the network, calls are routed to destinations using a dynamic look ahead routing mechanism and by predefined priority rules (priority preemption).
Depending on the location and hierarchy in the network, dispatchers are equipped with dispatch consoles ranging from special feature phones at the low end up to specialized touch screen terminals at the high end. The dispatch console allows the dispatcher to communicate with one or more dispatchers (pre-defined or ad hoc conferences) with a click of a button. Dispatchers can also view live feeds from critical nodes in the network (manned/unmanned) using Pan-Tilt-Zoom controlled CCTV cameras directly from the dispatch console. All the calls in the dispatch system are recorded and can be stored for future analysis and review.
