SENSORS FOR POWER DISTRIBUTION NETWORK AND ELECTRICAL GRID MONITORING SYSTEM ASSOCIATED THEREWITH

摘要

A network of sensors is associated with a power distribution network. Sensors are positioned at each connecting line in the vicinity of each node of the power distribution network. The sensors regularly report the following measured data to the central processing unit: a geographical position of each sensor, direction of the energy flow relative to the nearest node; and value of RMS current synchronously measured over the entire network and averaged over chosen averaging period. The central processing unit includes an arrangement for receiving the measured data and using this data for constructing and updating a graph and a state of the power distribution network.

1. A network of sensors associated with a power distribution network, said network of sensors, comprising:
sensors positioned at each connecting line in the vicinity of each node of said power distribution network, said sensors regularly reporting a measured data to a central processing unit, said reported measured data comprising: a geographical position of each said sensor; a direction of energy flow relative to the nearest node, and a value of Root Mean Square (RMS) current synchronously measured over the entire network and averaged over chosen averaging period; and said central processing unit including an arrangement for receiving said measured data and applying said data for constructing and updating a graph and the state of said power distribution network.
