Smart Energy Auditing using GSM and Fuzzy Logic Controller based Power Quality Management

A Majority of the current metering infrastructure lacks state-of-the-art security and smartness of the digitalized world. Recently GSM based Smart Energy meters have been implemented on a moderate scale. However they do not facilitate user control of the loads remotely or further processing of the Smart Energy data for power theft or quality. In the case of Power quality, Fuzzy Logic Controller provides an intriguing alternative for control of the OLTC. In our paper, a comprehensive model of Smart Energy Auditing and Load Management has been implemented, operated by a dedicated Android Application. A cohesive solution to theft detection has been proposed for on-site as well as line tampering detection. Furthermore, voltage fluctuation has been proposed to be eliminated using an AVC relay and OLTC transformer with the incorporation of an FLC. The former is carried using an Energy meter, a GSM module and an 8051 microcontroller. The functions can be controlled from a mobile application that handles the cost management, load control as well as alerts the customer regarding the same remotely. The latter is simulated using MATLAB Simulink. We observe the different cases of power fluctuation and the corresponding tap changes of the OLTC. Thus, the problems of peak loading, power quality and power theft are solved.
