The paper proposes a novel multi-area state estimator based on wide area measurements where only boundary buses are considered in the coordination level. The power injection measurements are not used during the coordination level reducing the number of states and therefore size of the problem. Instead, a set of pseudo-measurements are included whenever a power injection measurement is available...

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...

Phasor measurement units (PMUs) are important devices for protection, monitoring, and control of modern power systems. Unlike the supervisory data acquisition (SCADA) system which only measure magnitude, PMUs can provide a set synchronized phasor measurements with high sampling rate accuracy less than one second, better monitoring especially during outages. Since costly devices, operator is not...

This paper proposes a SUGPDS model based on Detection and Isolation algorithm smart sensors, namely micro phasor measurement unit, sensing switching device, data concentrator, ZigBee technology, etc. for the identification, classification, isolation of various fault occurs in underground power cable distribution system. The proposed is quick tool supervising, managing, controlling faults issues...

This article presents a study on real-time testing of synchrophasor-based “wide-area monitoring system’s applications (WAMS application).” Considering the growing demand monitoring, protection, and control (WAMPAC)” applications, systematic methodology is formulated delineated in diagrams. The diagrams propose several stages through which an application needs to be assessed (sequentially) for i...

-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...

State estimation is the foundation of any control and decision making in power networks. The first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. This paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...

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. ...
