An 8 mm-band two-dimensional Synthetic Aperture Interferometric Radiometer (SAIR) called BHU-2D has been developed by Electromagnetics Engineering Laboratory of Beihang University. The radiometer could obtain images in real-time benefiting from the adoption of a 1 bit/2 level FPGA-based correlator array. The correlator array requires a group of Power Measurement Units (PMUs) to denormalize the ...

This paper presents a novel algorithm for recovering missing data of phasor measurement units (PMUs). Due to the low-rank property of PMU data, missing measurement recovery can be formulated as a low-rank matrix-completion problem. Based on maximum-margin matrix factorization, we propose an efficient algorithm based on alternating direction method of multipliers (ADMM) for solving the matrix co...

This paper presents a procedure by which new PMU locations can be systematically determined in order to render an observable system. The procedure is then extended to account for cases of loss of a single phasor measurement unit (PMU). Buses with zero and non-zero injections, and branches with power flow measurements are also accounted for in this generalized procedure. Several cases involving ...

This paper presents a tri-objective Optimal Phasor Measurement Units (PMUs) Placement (OPP) strategy that is focused on the minimization of i) total number PMU channels, ii) maximum state estimation uncertainty based only high-rate data and iii) sensitivity to line parameter tolerances. The proposed formulation keeps into account system observability with without contingencies due single-line f...

Micro-phasor measurement units (µPMUs) with a micro-second resolution and milli-degree accuracy capability are expected to play an important role in improving the state estimation distribution network increasing penetration of distributed generations. Therefore, this paper investigates problem how place limited number µPMUs improve accuracy. Combined pseudo-measurements supervisory control data...

Abstract Large-scale power grid observability is still a challenge because of deteriorating infrastructure and the incorporation renewable energy sources. A smart that makes use cutting-edge technology, such as phasor measurement unit (PMU), an excellent option for monitoring bringing networks up to speed with latest information. Latterly, considerable investment required deployment locations h...

Abstract: Data from phasor measurement units (PMUs) may be exploited to provide steady state information to the applications which require it. As PMU measurements may contain errors and missing data, the paper presents the application of a Kalman Filter technique for real-time data processing. PMU data captures the power system’s response at different time-scales, which are generated by differe...

ue to the expansion of power systems there is a challenge of real time monitoring and control by placing important parameters at various points for efficient functioning of the power system. There can be drastic changes during hourly load fluctuations, component outages, or network switching. In such conditions, the inclusion of predicted values could degrade the power system state estimation h...
