Hardware in the Loop Protection Scheme of Compensated Transmission Lines With a Unified Power Flow Controller

This paper presents a Hardware in the Loop simulation for the detection, classification, and location of faults in transmission lines with Unified Power Flow Controller compensation. Hardware devices are proposed to demonstrate that the traveling wave concept for fault location in a Hardware in the Loop simulation is possible and replicable under laboratory conditions. The devices used are a MacBook Air M1 2020 computer to get the SIMULINK values from the local end of the transmission line, two FeelElec FY8300S generators to import the simulation data, then they send the signals to an AT91SAM3X8E microcontroller to perform the fault detection, when the cycle of the signals where the fault is obtained, they are sent to the UDOO BOLT v8 device to get the classification and location of the fault. The results obtained indicate that the error for estimating the fault distance is less than 0.71% of the total line length, and the classification efficiency is 94.18%.
