Power distribution feeders contains many laterals, sub-laterals, different number of circuit line, load taps, balanced and unbalanced load, different type of lines (cable or overhead), different cross-sections and numerous distribution transformers with different capacities. Moreover, the voltage and current are measured only at the beginning of the feeder. Thus, fault location is very complex....
Power system protection at transmission and distribution levels based on overcurrent relays is essential based on their properties such as detection, stability, high speed, backup and error correction accuracy. Since distributed generation sources are connected to the power grid, they not only increase the short circuit level of the grid, but also disrupt the set point of main and backup relays...
the well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. a new model that was previously proposed by the authors that combines a mass with a pulley (mp) is shown to simulat...
