Details regarding Phasor Measurement Unit (PMU) infrastructure installed in the New Zealand (NZ) transmission grid are presented. Currently, Phasor data are being used for model validation and monitoring network oscillations. Mathematical formulation of an Extended Complex Kalman Filter technique, a technique for oscillation monitoring, is proposed and its performance is assessed using real-disturbance...
International developments in phasor applications have demonstrated the potential of using phasor measurements to enhance network visibility. Most of these operational experiences are primarily for a large transmission grid or for a network connected to one. The motivation of this panel paper is to share New Zealand's experience and thus, provide a contrasting insight of Phasor development infrastructure...
The potential of parallel processing architecture is evaluated for power oscillation monitoring. In the emerging smart grid architecture using Wide Area Monitoring System (WAMS), data collected from Phasor Measurement Units (PMU) in remote locations are transmitted in real-time to the control center. The power system network oscillatory dynamic behavior can then be extracted online using modern signal...
Wide area monitoring system (WAMS) using phasor measurement units (PMU) is being implemented for online oscillation monitoring using Prony analysis. However sampling at inappropriate intervals, though satisfying Nyquist-Shannon criterion, can still cause the Prony analysis to inaccurately estimate damping factors and oscillating frequencies. Hence, this paper investigates possible ways for checking...
