“…For example, the spectral tools generally requires a constant sampling rate at which signal is sampled, e.g. for frequency estimation of power oscillations [3]. Also, this sampling/data rate should be constant throughout in the retrieved signal, to intact the precision in monitoring results.…”

“…[28], the monitoring illustrated here, is in real-time, which requires the 'PUPO-SADF' software-toolchain. To this end, the default function "SADF_run" was edited so that the SADF could plot the retrieved signals in real-time also plot the real-time MSC estimate and segmented-MSC estimate [3] between two signals, as can be seen in Fig. 6.…”

This article develops and demonstrates the software toolchain for real-time testing of synchrophasor based algorithms. Real-time testing procedure being the need of smart grid, requires to be hassle-free and easily accessible to the researchers. The developed software toolchain combines both MATLAB and opensource software. The toolchain requires recorded phasor measurement unit (PMU) or phasor data concentrator (PDC) signals, which are then played-back in real-time in the same computer using local sockets. The data is replayed using transmission control protocol/internet protocol (TCP/IP) sockets and the IEEE C37.111-2013 data transfer standard. The data is then retrieved and processed in real-time by any synchrophasor based algorithm in MATLAB. The toolchain is demonstrated with two examples, one that shows the main functionality by testing the connection with a PMU/PDC and another testing of a wide-area forced oscillation (FO) monitoring algorithm.

“…Ψ is just one index among several indices required to govern overall performance. For example, the application developed in [29] for oscillation monitoring utilized a mode decomposition technique, and thus, it will give low Ψ due to the heavy computation burden involved in comparison to a simple power spectral density (PSD) operation. On the other hand, the application developed by authors of [29] would give better oscillation detection results subjected to mode mixing problems [29].…”

This article presents a study on real-time testing of synchrophasor-based “wide-area monitoring system’s applications (WAMS application).” Considering the growing demand of real-time testing of “wide-area monitoring, protection, and control (WAMPAC)” applications, a systematic real-time testing methodology is formulated and delineated in diagrams. The diagrams propose several stages through which an application needs to be assessed (sequentially) for its acceptance prior to implementation into a production system. However, only one stage is demonstrated in this article which comprises the use of a prototyping software toolchain and whose potential is assessed as sufficient for preliminary real-time testing (PRTT) of WAMS applications. The software toolchain is composed of two components: the MATLAB software for application prototyping and other open-source software that allows ingesting prerecorded phasor measurement unit (PMU) signals. With this software toolchain, a PRTT study is presented for two WAMS applications: “testing of the PMU/phasor data concentrator (PDC)” and “testing of wide-area forced oscillation (FO) monitoring application.”

“…An equivalent power system model in the frequency domain considering noisy PMU data and uncertain generator parameters is developed in [21] and a numerical procedure based on Bayesian framework is adopted to identify the source of FO. Reference [22] proposes a double stage mode decomposition technique, while [23] discusses an unknown input observer (UIO) based method to locate the source of FO. Initially, the linearized power system model considering the unknown oscillation sources from a prime mover, excitation system etc.…”

Large interconnected power systems are usually subjected to natural oscillation (NO) and forced oscillation (FO). NO occurs due to system transient response and is characterized by several oscillation modes, while FO occurs due to external perturbations driving generation sources. Compared to NO, FO is considered a more severe threat to the safe and reliable operation of power systems. Therefore, it is important to locate the source of FO so corrective actions can be taken to ensure stable power system operation. In this paper, a novel approach based on two-step signal processing is proposed to characterize FO in terms of its frequency components, duration, nature, and the location of the source. Data recorded by the Phasor Measurement Units (PMUs) in a Wide Area Monitoring System (WAMS) is utilized for analysis. As PMU data usually contains white noise and appears as multi-frequency oscillatory signal, the first step is to de-noise the raw PMU data by decomposing it into a series of intrinsic mode functions (IMF) using Improved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (ICEEMDAN) technique. The most appropriate IMF containing the vital information is selected using the correlation technique. The second step involves various signal processing and statistical analysis tools such as segmented Power Spectrum Density (PSD), excess kurtosis, cross PSD etc. to achieve the desired objectives. The analysis performed on the simulated two-area four-machine system, reduced WECC-179 bus 29 machine system, and the real-time power system PMU data set from ISO New England, demonstrates the accuracy of the proposed method. The proposed approach is independent of complex network topologies and their characteristics, and is also robust against measurement noise usually contained in PMU data.
