Synchronized phasor measurement systems are being widely used around the world and have become essential elements in evolution of operation large electrical power (EPS). These systems, called Phasor Measurement Units (PMUs), capable recording communicating dynamic data from EPSs a synchronized way by GPS with high sampling rate, generate huge set that, among many applications, has capacity to d...

The conventional power system is going through a paradigm change towards smart grid, incorporating technological innovations for sensing, communicating, applying intelligence and exercising control through feedback. Recently, phasor measurement units (PMUs) have been used extensively for the purpose of sensing and communication. In many system planning studies, planners experience conflicts whi...

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. ...

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)...

The application of the Phasor Measurement Unit (PMU) in power system is expanding day by since it provides a higher reliability through fast symmetrically monitoring and protection assists controlling systems. For systems, islanding significant event due to its hazardous consequences. To detect events, several schemes have been previously proposed but inappropriate threshold setting, computatio...

Loss-of-mains protection is an important component of the protection systems of embedded generation. The role of loss-of-mains is to disconnect the embedded generator from the utility grid in the event that connection to utility dispatched generation is lost. This is necessary for a number of reasons, including the safety of personnel during fault restoration and the protection of plant against...

Due to the high penetration of renewable energy sources, such as photovoltaic panels and wind turbines, in addition use different electric power supplies grid, there are major disturbances forms waves. These variations must be monitored controlled for efficient management transmission distribution electrical energy, safety, protection systems. Nowadays, Phasor Measurement Unit (PMU) technology ...

Recent work on complex networks compared the topological and electrical structures of the power grid, taking into account the underlying physical laws that govern the electrical connectivity between various components in the network. A distance metric, namely, resistance distance was introduced to provide a more comprehensive description of interconnections in power systems compared with the to...
