Smart grid plays a vital role to protect electrical load and utilities among electrical power consumers due to its wide range of advantages which in turn made up its growing demand in current world. Mostly, electrical loads are venerable to fault current in the system results in sudden failure of expensive loads which is needed to be detached for safety reason. Therefore, this paper mainly focuses on designing the circuit in generating a fictitious fault current and its detection through WiMAX communication so as to detach the load from power generation unit using Matlab Simulink. In order for transmission of fault or trip current through wireless communication system, a WiMAX transceiver IEEE STD 802.16d has been designed, implemented and optimized for trip current transmission and receiption to certain distant places circuit breakers located in different HV and LV distribution system. Moreover, an automatic back-up system has been proposed to provide an uninterruptable power to the utilities/load during when the fault current occurs. Finally, the simulation result shows a successful transmission and detection of fault signal along with its impact in load end is evaluated for overall performance of the designed system.
