MONITORING AND CONTROLLING OF ELECTRICAL LOADS FROM THE SUBSTATION BY USING ZIGBEE TECHNOLOGY

This paper proposes an innovative design to develop a system to monitor and control various electrical loads from the substation. The design generally consists of two units, one in the substation unit, called as transmitter unit, and another one is the Main station called as controlling and receiving unit. The transmitter unit is where the power is monitored continuously by PIC (Peripheral Interface Controller) microcontroller. Zigbee is used for transmitting the signals that are obtained. The controlling unit in the main station receives the transmitted signals by means of zigbee receiver and displays in the laptop and reacts in accordance to the received signal.
