Transient Stability Prediction based on Synchronized Phasor Measurements and Controlled Islanding
… PMUs data. It predicts transient stability using apparent impedance trajectories obtained from PMUs, decision trees, and FLDSD method. This method enables to find out the strategic locations for PMUs installation in the power system to rapidly predict transient stability. From the simulations …

Next-generation, phasor-based distance relay with fault-path resistance immunity
… lines. A distance relay calculates the apparent impedance between the relay location and the fault location, and uses this value to determine the approximate location of the fault. Traditional distance relays, however, are plagued with problems caused by faults through a resistance. The …

A novel backup protection scheme for hybrid AC/DC power systems
… protection. The protection scheme relies on the apparent impedance measured at the AC "side" of the MVDC link to detect faults on the DC system. It can be readily implemented on existing distance protection relays with no changes to existing measuring equipment. An overview of the literature in …

ESTIMATING LOCATIONS OF SHUNT FAULTS ON DISTRIBUTION LINES
… line shunt faults has been to measure the apparent impedance to the fault from a line terminal and convert the reactive component of the impedance to the line length. Several methods, that use the fundamental frequency voltages and currents measured at one or both line terminals, for …

A New Special Protection Scheme for Power System Controlled Separation
A new power system controlled separation scheme is proposed to prevent the propagation of cascading failures across a transmission network should it undergoes a major disturbance, thereby reducing the possibility of a large-scale blackout. This scheme is developed based on a set of conjectures, …

PMU-Driven Fault Location in Distribution Systems with DERs: Impedance-Based and Multi-Agent System Strategies
… in fault detection, particularly for high-impedance faults (HIFs). These complexities highlight the necessity of accurate fault location techniques to support efficient repair dispatch, minimize outage impacts, and maintain overall grid reliability. This research aims to enhance system …
