| Summary: | This document presents the implementation and design of virtual directional overcurrent relays (DOCR) by using a soft real-time platform validating selectivity, sensibility, and speed of the system protections. As a key contribution, the implemented system involves transient configurations due to a difference in the breaker trip time that lead to problems of selectivity in the system when relay settings are not properly. For the last, it was developed in Typhoon HIL a DOCR model where his operation times are calculated by using inverse curves and the power flow direction through phase-quadrature measures. In the same manner, it was implemented an electric power system taking into account three-phase transmission lines couplings, transients topologies, pre-fault conditions, symmetric fault currents, and the possibility to add in the system a current transformer. This was developed using a 150 [kV] interconnected system power with 8 nodes, 7 transmission lines and 14 directional overcurrent relays (Function 67). As a result, through oscillographic and digital outputs is possible to determine operation times of relays associated with a fault and appreciate if their operation is selective. As a novel in this project, are integrated a total of fourteen simultaneous virtual relays, which allows to analyze adequate coordination of protective relays of the complete system. |
