20.500.12556/RUL-155115 Precise PMU-based localization and classification of short-circuit faults in power distribution systems Knowing the exact location of a short-circuit fault in a power distribution system (PDS) is essential for rapid restoration of service to customers and has a direct impact on the operational costs and reliability of the system. In this paper a phasor measurement unit (PMU) based method for fault localization and classification is presented. By introducing the concept of a virtual bus, the exact fault location on the line is determined rather than just a bus closest to the fault. Moreover, after determining the fault location, a generic fault model (GFM) is introduced to classify the type of fault by solving a minimization problem, which also provides fault impedances as a result. These can then be further used to determine if the fault occurred on the lateral instead of the main feeder without using additional PMU at the end of that lateral. The effectiveness of the proposed approach is verified by simulating various fault scenarios in two test systems based on real PDSs using a real-time digital simulator. In addition, a sensitivity analysis of the method is performed for different noise levels in the input parameters to verify its applicability to the real system. fault classification fault localization phasor measurement unit PMU location awareness circuit faults impedance fault location monitoring power system reliability telekomunikacije natančna lokalizacija PMU napake kratkega stika true false true Angleški jezik Slovenski jezik Članek v reviji 2024-03-20 15:35:54 2024-03-20 15:35:56 2024-03-21 04:07:10 0000-00-00 00:00:00 2023 0 0 Str. 3262–3273 no. 5 Vol. 38 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.39 1937-4208 10.1109/TPWRD.2023.3268767 150009603 Precise_PMU-Based_Localization_and_Classification_of_Short-Circuit_Faults_in_Power_Distribution_Systems.pdf Precise_PMU-Based_Localization_and_Classification_of_Short-Circuit_Faults_in_Power_Distribution_Systems.pdf 1 D1725C17CFC3FBBB03033C6434C18523 250a4872f1903388e0a6638d03b03f85626e780715cd2a199e1b73f891271a0e 294e12f0-e6c8-11ee-8d8c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181899 https://ieeexplore.ieee.org/document/10106028 0 15d5f903-e6c8-11ee-8d8c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181898 Fakulteta za elektrotehniko 0 0 0
