Smart Power Grid


The electrical grid is an interconnected system of power plants, power lines,
wires, etc. moving and delivering electricity from power plants to end users. Also
referred to as a transmission and distribution (T&D) network, today’s grid faces
challenges to keep pace with the modern digital economy and information age, which
require higher load demands, uninterruptible power supplies, and other high-quality,
high-value services. Micro Controller is placed at intervals to detect the power usage
as well as the power consumption at that point. All these controllers are connected
together & information like voltage & current consumed is then sent serially to a
central computer. If there is a problem in one area then that area can be cut off
temporarily from the central computer. Moreover parameters such as transmission
power loss, power consumption during different time of the day & power theft can
also be detected.Each sensing unit will consists of a current transformer for sensing
the current, whose o/p is given to ADC the digital data from the ADC is read by the
controller, the controller(8951/8952) is connected to the central computer using
DS75176 which is used for multipoint communication. The sensing unit also
contains relays which are used to divert power or cut off power in specific area.
