This paper proposes an accurate fault location method for underground power cable in power distribution systems. The cable is modelled using PSCAD EMTP simulation tool. The cable core as well as sheath and various grounding modes were considered in the cable modelling. The algorithm uses voltage and current measurements recorded at the terminal where the fault locator is placed. The simulation studies...
This paper introduces a fault localization algorithm for 66/132 kV electric power sub-transmission lines. The fault locator utilizes voltage and current phasors from Disturbance Fault Recorders (DFR) at sending end terminal of the transmission line. The proposed method has been proved for accuracy under different system as well as fault conditions using EMTP/PSCAD simulations. Further, the algorithm...
This paper proposes a new efficient and accurate fault location technique for modern distribution systems with integrated Distributed Energy Resources (DER).The algorithm requires only the voltage and current phasor information from source end of the system in case of a fault event. The main advantage is that it does not require any measurements from the Distribution Generation (DG) node, since it...
Wide Area Monitoring Systems (WAMS) have recently become a prominent technology that helps in improving the visibility and situational awareness of the power grid. This technology employs Phasor Measurement Units (PMU) widely and extensively, and they are synchronized using a global positioning system clock to provide time-synchronized voltage and current phasors at the points of employment. This...
This paper presents an extensive fault location algorithm for in an electrical energy distribution system. The algorithm requires phasor information comprising of voltage and current data from one end of the system in case of a fault event in an electrical distribution system. This algorithm can be used online or offline using the data stored in Digital Fault Recorder (DFR). The proposed fault location...
