Item Design and implementation of an overcurrent digital relay(2018) Medjber, Brahim; Benmouffok, Youcef; Metidji, Brahim (Supervisor)A model based design approach has been applied in this thesis for the development of an overcurrent protection relay, having both the instantaneous characteristics and the inverse time current characteristics as per IEEE standard C-37.112-1996. (ANSI 50, 51). This approach highly accelerates and simplifies the design. MATLAB Simulink has been used for the development of the model and Simulink HDL coder has been used to generate the VHDL code. The code generation is supported by keeping certain constraints like fixed point data type in the design during system development. This generated code is used for verification and implementation of the designed model. The digital simulation of the generated codes and test bench has been performed on ModelSim Digital Simulator. In this work, a hardware platform for power line communications was implemented to be used with the relay and give it a communicative functionality. This allows the relay to coordinate its decisions with its adjacent peers enhancing its selectivity.Item Design and implementation of an overcurrent digital relay(2018) Medjber, Brahim; Benmouffok, Youcef; Metidji, Brahim (Supervisor)A model based design approach has been applied in this thesis for the development of an overcurrent protection relay, having both the instantaneous characteristics and the inverse time current characteristics as per IEEE standard C-37.112-1996.
