This paper proposes an approach based on trajectory sensitivity analysis (TSA) to find most suitable placement of series compensators in the power system. The main objective is to maximize the benefit of these devices in order to enhance the rotor angle stability. This approach is formulated as a two-stage problem, whose first-stage describes prior to fault occurrence and whose second-stage rep...

Detection and prevention of faults in overhead electric lines is critical for the reliability availability electricity supply. The disadvantages conventional methods range from cumbersome installations to costly maintenance lack adaptability hazards human operators. Thus, transmission inspections based on unmanned aerial vehicles (UAV) have been attracting attention researchers since their ince...

considering that once-through benson boiler is one of the most crucial equipment of a thermal power plant, occurrence of any fault in its different parts can lead to decrease of the performance of system, and even may cause system damage and endanger the human life. in this paper, due to the high complexity of the system's dynamic equations, we utilized data-based method for diagnosing the faul...

In this paper, a novel method is presented for detection and classification of the faultyphase/region in the stator winding of synchronous generators on the basis of the resulting harmoniccomponents that appear in the terminal voltage waveforms. Analytical results obtained through DecisionTree (DT) show that the internal faults are not only detectable but also they can be classified andthe rela...

This paper presents a new selective and non-directional protection method to detect ground faults in neutral isolated power systems. The new proposed method is based on the comparison of the rms value of the residual current of all the lines connected to a bus, and it is able to determine the line with ground defect. Additionally, this method can be used for the protection of secondary substati...

The increased accuracy of the faults’ location is a very actual request of the power grids’ operation and management, reason to develop new and as precise as possible techniques for the estimation of the shortcircuits’ location. The actual fault locating techniques use algorithms based on power frequency quantities or on traveling waves principles, both categories of such fault locators being d...

This paper describes a method of identifying a set of crosstalk-induced delay faults which may need to be tested in synchronous sequential circuits. In this process, the false crosstalk-induced delay faults that need not (and/or can not) be tested in synchronous sequential circuits are also identify. Our method classifies the pairs of aggressor and victim lines, using topological information an...

As wildfires in the United States are becoming more frequent and severe, mitigating risk of wildfire ignitions from power line faults is an increasingly crucial effort. Long-term ignition prevention strategies, especially converting overhead lines to underground cables, expensive. Thus, it important prioritize upgrades on that will reduce most. However, since so many factors contribute risk, di...
