A Robust Scheme for Coherency Detection in Power Systems
This paper presents an approach for online generator coherency identification based on windowed dynamic time warping (DTW). Generator rotor speed deviations measured by phasor measurement units (PMUs) are used as input data to compute a DTW ...

Experience in implementing the algorithm for emergency control system of unloading in case of overload in terms of power based on synchrophasor angle [PDF]
An algorithm for automatic unloading during a power overload is described. It is based on measurement of the phase angle between voltages on the Tyumen - Ural power transmission line, which is determined by information from phasor measurement units.

Measurement accuracy verification of phasor measurement unit with dynamic phasor estimation
Power systems that are highly loaded, especially by a stochastic supply of renewables and the presence of storages, require dynamic measurements for their optimal control. Phasor measurement units (PMUs) can be used to capture electrical parameters of a power system.
