SMART MONITORING NETWORK FOR POWER GRIDS USING BLUETOOTH TECHNOLOGY

This paper proposes a grid impedance monitoring system for distributed power generation electronic interfaces and informs the same to authorized person via smart phones using Bluetooth technology. Thus the grid can be monitored remotely using Bluetooth. The system estimates the grid equivalent impedance, voltage source from the voltage measurements and also frequency by using different sensors performed at the point of common coupling. Simultaneously, the system evaluates the quality of the estimation, minimizing its influence on the grid and detecting islanding situations. The proposed system performance has been evaluated under experimental testing.
