Maloperation of conventional relays is becoming prevalent due to ever increase in complexity of conventional power grids. They are dominant during power system contingencies like power swing, load encroachment, voltage instability, unbalanced loading, etc. In these situations, adaptive supervised wide-area backup protection (ASWABP) plays a major role in enhancing the power system reliability. ...

Characterization of spatial and temporal changes in the dynamic patterns of a nonstationary process is a problem of great theoretical and practical importance. On-line monitoring of largescale power systems by means of time-synchronized Phasor Measurement Units PMUs provides the opportunity to analyze and characterize inter-system oscillations. Wide-area measurement sets, however, are often rel...

Large power system disturbances and their consequences, represent a challenging problem for the power industry and especially for the network system operators, the ones who are responsible for the network operation at large, its security and reliability. This fact has reinforced interest in the new generation of monitoring systems with the aim to gain if possible a precise and maximum knowledge...

We study the communication network of an on-campus active distribution network (ADN) that comprises phasor measurement units (PMUs) connected to medium-voltage transformers. Within stringent time delays and with minimal loss the PMUs periodically transfer fresh measurements through a phasor data concentrator (PDC) to a centralized electrical network state estimator (control point). Due to stric...

Monitoring of a power system is essential for maintaining it in secure operating condition. Electric distribution management (DMS) should possess monitoring mechanism addressing the entire conditions system. Distribution System State Estimation (DSSE) an integral building block DMS. Because new technologies integrated into system, opportunities, problems and challenges related to control are be...

Abstract – This paper proposes a PMU (Phasor Measurement Unit) based power oscillation detection system. The phasor angles at domestic 100V power outlets are collected to the server PC through internet, and the power oscillations and their various parameters are detected from the phasor angles. PMUs and servers are installed to Japanese 60Hz system, which is a large-scale longitudinal power sys...

-After two decades of phasor network deployment, phasor measurements are now available at many major substations and power plants. The North American SynchroPhasor Initiative (NASPI), supported by the US Department of Energy and the North American Electric Reliability Corporation (NERC), provides a forum to facilitate cultivating the efforts in phasor technology in North America and globally. P...

Safe operation and reliability of the electrical power systems necessitate full observability of the power grid. Phasor measurement units (PMUs) are the state-of-the-art intelligent devices that collect synchronized phasors of voltages and currents in real time. It is not economically justifiable to install PMUs at all buses of the power grid. Hence, designing the PMUs network and determining t...

Owing to the technological advancement in communication areas, presently, the security and the reliability of operating power system is very much possible on real-time platform. Phasor measurement units (PMUs) are based on these advance communication technology and are one of the most important equipment for electric utility, now a days, helpful in maintaining a healthy operating power system. ...

In this paper, the modeling for a complete scenario of a proposed wide area measurement system (WAMS) based on synchronized phasor measurement units (PMUs) technology with the access of a broadband communication capability is presented. The purpose is to increase the overall system efficiency and reliability for all power stages via significant dependence on WAMS as distributed intelligence age...
