The phasor measurement unit (PMU) commonly implements enhanced discrete Fourier transformation (EDFT) to compensate leakage and signal discontinuity errors at offnominal frequencies. However, EDFT results in a high total vector error (TVE) at large offnominal frequency and worsens with harmonics in power signals. Although the sample value adjustment (SVA) technique addressed such demerits, it generates...
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 adaptive Power System Stabilizer (PSS) tuning method for damping inter-area oscillation is presented in this paper. The primary focus is to adaptively improve the observability of the PSS reflecting the changing operating conditions in order to achieve effective damping towards Inter-Area oscillations. The proposed design approach is considered to be an indirect approach since the PSS parameters...
