Abstract:
The increase in renewable generation in the grid has brought new challenges for the protection systems currently installed in distribution and transmission networks. Among these challenges is the potential misoperation of the faulted phase selection logic currently implemented in many commercial protection relays. This article presents a Faulted Phase Selec-tion (FPS) algorithm based on incremental line-to-line voltages. Considering the advantages of IEC 61850 standard, the algorithm is implemented in a computer-based system using C++ code. The FPS operation is tested in Hardware-in-the-Loop (HiL) mode using a Real Time Digital Simulator (RTDS). Different fault conditions are considered during the test, varying fault type, resistance, and location. Furthermore, evolving faults are also included in the tests. From the study, it is concluded that the proposed algorithm operates correctly in all the analyzed scenarios.
