In order to improve the efficiency and safety of the grid, monitoring and automating the system became mandatory. In Indian grids, the line parameters are not monitored continuously which results in conditions such as blackouts, overloading of the power system elements, such conditions can be avoided by timely monitoring the parameters and taking necessary actions to avert the future intolerable conditions on the line. This paper proposes an architecture for monitoring smart grid using wireless sensor network (WSN) technology. A miniature smart grid prototype and sensing module is designed and implemented to collect the line parameters like current, voltage and frequency. Using WSN technology, the collected parameters are communicated to a central monitoring unit at periodic intervals.
