The widespread application of phasor measurement units has improved grid operational reliability. However, this increased the risk cyber threats such as false data injection attack that mislead time-critical measurements, which may lead to incorrect operator actions. While a single action might not result in cascading failure, series actions impacting critical lines and transformers, combined w...

The practical implementation of phasor measurement unit (PMU)-based fault location in high-voltage overhead lines presents a number difficulties including the significant impact DC components current wave-form and residual magnetization transformer. Synchrophasor technology was only meant to capture steady states electromechanical transients. issues mentioned above indicate need for changes syn...

Traditional power system dynamic models are very complex due to the intricacy of power system networks and can be inaccurate for control because of the amount of details needed and the fact that the grid topology changes all the time. With the fast deployment of a large number of phasor measurement units (PMUs) in the transmission network, a purely measurement-based model for dynamics estimatio...

The electrical quantities of future power networks are expected to exhibit strong fluctuations caused by dynamic bidirectional energy flows transferred from/to a multitude of “prosumers”. Such variations have to be accurately measured in real-time either for efficient power distribution or for safety and protection purposes. This task can be accomplished by the Phasor Measurement Units (PMUs), ...

Recent advances on synchro phasor measurement along with its regulation by the Operador Nacional do Sistema – ONS brought access to high resolution data rates up one sample per cycle. Electrical power system current, voltage, phase and frequency are collected through Phasor Measurement Units-PMUs stored in Data Concentrators PDCs. Such high-resolution favours new algorithms applications towards...
