Controlling and Monitoring of Electric Feeders Using GSM Network Technology
Abstract
The application of computer interfaced controlling devices is increasingly rapidly in modern age. Analogous wired systems are substituted by computer interfaced system alternatives in growingnumber of industries. Such control systems had been developed with complex and critical high-end stuffs. In this paper, we developed an automated system that controls the switching of electric feeder power supply featuring the existing GSM technology. The target is tooperate the device according to a preset sequence of on-off mode for three feeders after a particular time interval and to monitor the running condition. The device sends short message updating the status of every action. It also warns the consumers about load shedding using GSM module via sending message. Controlling the gate pulse of a MOSFET that operates the relay, it executes on-off operation of the circuit breaker of the respective feeders. Since GSM technology is used worldwide for communication, third world countries that are still struggling to meet the power demand can use this technology to operate and monitor the condition of power distribution. To operate the GSM device, AT command of GSM location operation for SIM900 is used. This paper targets to improve the power distribution system in developing countries like India, Bangladesh, Nepal where powercrisis and load shedding is quite a common phenomenon.
