Our Mini-Substation Monitoring System is a self-contained unit providing substation monitoring and wireless communications that is designed to be easily installed or integrated into power substations. The core of the device is comprised of a microcontroller, and a current sensor mounted on a printed circuit board. In addition, a relay is also incorporated into the device to serve as a breaker should a fault condition occur. The fault conditions will be predetermined by the consumer and designed to meet the requirements of the application. The system also consists of a small liquid crystal display (LCD) so real-time conditions of the substation can be observed. The exterior of the housing contain's a light emitting diode (LED). This will be automatically activated at an indication of trouble with the system. The single LED could also be upgraded to a cluster of LED’s which would be visible from a much greater distance, however for purposes of the prototype demonstration, the system will only utilize a single LED. Information collected from the current sensor is sent via an integrated wireless device to a transceiver connected to a nearby laptop computer. The laptop computer contains a graphical user interface that displays information collected from the substation monitor’s sensors. The software also is capable of developing trend data for easy identification of high and low usage times and condition trends. Once a fault condition is relayed to the user interface, the computer alterts the user.
