Phasors representing positive sequence voltages and currents ih a power network are the most important parameters i n several monitoring, control, and protection functions i n interconnected electric power networks. Recent advances in computer relaying have led to very efficient and accurate phasor measurement systems. When the phasors to be measured are separated by hundrea of miles, i t becom...

BabelFish (BF) is a real-time data mediator for development and fast prototyping of synchrophasor applications. BF is compliant with the synchrophasor data transmission IEEE Std C37.118.2-2011. BF establishes a TCP/IP connection with any Phasor Measurement Unit (PMU) or Phasor Data Concentrator (PDC) stream and parses the IEEE Std C37.118.2-2011 frames in real-time to provide access to raw nume...

Voltage instability is a crucial issue in the secure operation of power grids. Several methods for voltage stability assessment were presented. Some of them are highly computationally intensive, while others are reported not to work properly under all circumstances. This paper proposes a new methodology based on the generator equivalent circuit model (GECM) and the phasor measurement unit (PMU)...

Modern power system requires advanced and intelligent sensors-based protection such as a Phasor Measurement Unit that can provide faster, accurate, real-time data acquisition. The aim is to allow accurate action-based performance for analysts in monitoring the transmission lines so rapid actions be taken during abnormal circumstances before blackout occurs. Among different algorithms, this stud...

The Phasor Measurement Unit (PMU) is considered to be one of the most important measuring devices in the future of power system. The difference comes from its unique ability to provide synchronized phasor measurements of voltages and currents from widely dispersed locations in an electric power grid called synchrophasor technology .In SCADA system, the measured quantities remain constant during...

This paper deals with an improved use of phasor measurements. In particular, the paper focuses on the development of a technique for estimation of generator rotor angle and speed, based on phasor measurement units, for transient stability assessment and control in real-time. Two multilayered feed-forward artificial neural networks are used for this purpose. One for the estimation of rotor angle...

The objective of this paper is to find numerical bounds on the performances of algorithms for the placements of phasor measurement units (PMUs) in the power grid. Given noisy measurements and knowledge of the state correlation matrix, we use a linear minimum mean squared error estimator as the state estimator to formulate the PMU placement problem as an integer programming problem. Finding the ...
