Compliance Analysis of PMU Algorithms and Devices for Wide-Area Stabilizing Control of Large Power Systems
TLDR
In this article, two different frequency-adaptive approaches for class-P and -M compliance to ensure operation over a wide frequency range were considered. And the authors concluded that a class-M PMU is unsatisfactory for wide-area stabilizing control, unless its performance is improved during the fault period.Abstract:
For the first time, IEEE Std. C37.118.1-2011 now provides metrics for PMU dynamic performance in terms of classes P and M filter designs. This paper attempts to determine whether fulfilling these requirements makes the PMU inherently well suited for stability control applications such as wide-area power system stabilizers (PSSs). In this aim, we considered two different frequency-adaptive approaches for class-P and -M compliance to ensure operation over a wide frequency range. The first is based on a finite-impulse response (FIR) with no overshoot in either the phase or the amplitude step responses, while the second is Kalman filter-based (EKF), which allows for a more refined out-of-band interference rejection at the cost of a phase step response with overshoot. These two approaches are benchmarked against Hydro-Quebec`s existing PSS requirements and the conclusion is that the total vector error-based response time is not indicative of the phase lag within the frequency band of interest, nor of the 3-dB bandwidth under sinusoidal amplitude/frequency modulation phenomena, which are key criteria when specifying PSS PMUs. Using simulated and field-recorded network fault responses, we also show that a class-M PMU is unsatisfactory for wide-area stabilizing control, unless its performance is improved during the fault period, which is not covered by Std. C37.118.1-2011.read more

Wide Frequency Range Adaptive Phasor and Frequency PMU Algorithms
TL;DR: It turned out that FIR PMUs are best for meeting Std C37-118-1 metrics but they are outperformed by EKF under changing harmonics, and test results on three recent commercial PMU models further confirm that PMU algorithms meeting standard C 37- 118-1 can behave quite differently under dynamic conditions.
