Methodology for Modeling and Implementation in Hardware-in-the-loop of Fuses and Overcurrent Protections

This paper presents the results obtained of the simulation and implementation in hardware in the loop of fuses and overcurrent protections. First, the steps developed for construct the different blocks in MATLAB/SIMULINK considering the details for the curve approximation in the fuses are presented. Consequently, their implementation using the Dspace 1104 and TI 280F337S boards are presented, describing the characteristics of the signals measurement and the construction of the tripping module and interconnection of all the components of the test grid. Finally, the results obtained in simulation and those obtained whit the hardware in the loop system are compared.
