Electric power system
A network supplying, transferring, and using electric power.
An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example is the electrical grid that provides power to homes and industries within an extended area. The grid can be broadly divided into generators, transmission systems, and distribution systems. Smaller power systems are found in industry, hospitals, commercial buildings, and homes. The majority rely upon three-phase AC power, the standard for large-scale power transmission and distribution. Specialized power systems that do not always rely upon three-phase AC power are found in aircraft, electric rail systems, ocean liners, submarines, and automobiles.
Lore & Background
However, supply was intermittent. That same year in London, Lucien Gaulard and John Dixon Gibbs demonstrated the first transformer suitable for use in a real power system, later used in 1884 at Turin to light 40 kilometers of railway. That same year, Mikhail Dolivo-Dobrovolsky and Charles Eugene Lancelot Brown built the first long-distance high-voltage three-phase transmission line.
Reader's Guide
The electric power system is fundamental to modern civilization, enabling the supply, transfer, and use of electric power for homes, industries, and specialized applications. Its development involved key innovations: the transformer, which allowed efficient voltage transformation and long-distance AC transmission; the parallel AC distribution system, which improved reliability; and the polyphase AC induction motor, which expanded power use beyond lighting. In recent times, innovations in information and communications technology have improved load flow studies and remote control of power systems. The system's significance lies in its ability to deliver power efficiently over distances, support diverse applications, and adapt through technological evolution.
