The detection and localization of faults plays a huge role in every electric power system, be it transmission network (TN) or distribution (DN), as ensures quick restoration thus enhances the system’s reliability availability. In this paper, framework that supports phasor measurement unit (PMU)-based fault is presented. Besides making process detecting, localizing reporting to control center fu...

Abstract The power system stability and reliability are stimulated by the faults on transmission line. Many researchers have explored performance of under various kinds faults. Specifically, arrival expeditious effective data acquisition systems with high rate sampling has set down foundation for successful real-time monitoring. Using LabVIEW system’s National Instruments (NI), virtual been dev...

Timely remote activation of frequency response, provided by converter-based generation, can improve the damping very low-frequency (VLF) oscillations. The research presented is based on both power system models and actual data from phasor measurement units (PMU) Irish system. performance active control (APC) investigated, variations in wind speed, droop, time lag resource capacity demonstrate t...

In this paper, the load response-based equivalent model is proposed to develop a more sturdy method for transmission capability estimation of power grid. Based on real-time phasor measurement unit (PMU) measurements, grid modelled as multi-port based coupled single-port models. The associated critical branch in identified and modified by shaping factor construct model. According modification, d...

The smart grid will be a power grid more “aware” of its operating state and having the ability to self-heal. These features may be incorporated into the grid by implementing a phasor measurement units based wide area measurement system. Such a system will help in better real time monitoring and control of the grid. However, the wide area measurement system is subject to challenges with respect ...

Phasor Measurement Units (PMUs) are starting to see increased deployment, enabling accurate measurement of power grid electrical properties to determine system health. Due to the costs associated with PMU acquisition and maintenance, it is practically important to place the minimum number of PMUs in order to achieve system complete observability. In this paper, we consider a variety of optimiza...

Modern power systems are rapidly transitioning towards a fully digital substation paradigm. Based on the IEC 61850, common communication protocol between different intelligent electronic devices (IEDs) promises significant enhancement in terms of efficiency and interoperability. In this context, synchronization represents crucial aspect as it allows us to rigorously compare measurements taken a...

This thesis proposes a method to analyze power system stability by utilizing PMU measurements. As the current power system is operated close to its limits, stability is of high concern for both operators and customers. The implementation of phasor measurement units across the power system allows for accurate and fast stability monitoring and analysis. To address the application of PMU measureme...

Phasor measurement units (PMUs) deployed to monitor the state of an electrical grid need to be patched from time to time to prevent attacks that exploit vulnerabilities in the software. Applying some of these patches requires a PMU reboot, which takes the PMU offline for some time. If the PMU placement provides enough redundancy, it is possible to patch a set of PMUs at a time while maintaining...
