A Brazilian PMU-WAMS pilot project: A methodology for PMU site selection
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The stability of interconnected large power systems — like the Brazilian National Grid (SIN) — is directly compromised by weakly or not damped low frequency oscillations and transitory oscillations, these latter originated from large contingencies.

PMUs [phasor measurement unit]
IEEE Potentials, 1994In the spring of 1993, a major new 500 kV transmission line was put in service in Northern California. Test engineers initiated a series of artificial short-circuit faults to test the line installation. As an experiment, the steady-state and transient responses of the power system were recorded.

Taxonomy of PMU Placement Methodologies
IEEE Transactions on Power Systems, 2012Utilization of phasor measurement units (PMUs) in the monitoring, protection and control of power systems has become increasingly important in recent years. The aim of the optimal PMU placement (OPP) problem is to provide the minimal PMU installations to ensure full observability of the power system. Several methods, based on mathematical and heuristic

Reliability-Based Incremental PMU Placement
IEEE Transactions on Power Systems, 2014This paper presents a new reliability-based incremental phasor measurement unit (PMU) placement method via an enumeration-based integer linear programming optimization approach. By evaluating the proposed reliability indices for node and system observability, incremental PMUs are sequentially placed on the locations where the reliability of entire ...

Transmission line identification using PMUs
2011 10th International Conference on Environment and Electrical Engineering, 2011The paper is devoted to the identification of transmission lines from synchronized measurements of current and voltage phasors provided by the phasor measurement units (PMUs). The series and shunt line parameters are recursively estimated using the extended Kalman filter (EKF).

PMU Based System Protection Scheme
2014 IEEE Electrical Power and Energy Conference, 2014Phasor Measurement Units (PMUs) are being widely installed in modern power systems worldwide. The most important advantage of PMUs is their capability to provide fast, reliable and synchronized real-time measurements of different system parameters. This characteristic leads to an essential role of PMUs in real-time monitoring, advanced power system ...

Security breaches as PMU deviation
Proceedings of the Second Asia-Pacific Workshop on Systems, 2011This paper considers and validates the applicability of leveraging pervasively-available performance counters for detecting and reasoning about security breaches. Our key observation is that many security breaches, which typically cause abnormal control flow, usually incur precisely identifiable deviation in performance samples captured by processors ...
