Abstract

This paper focuses on a novel method for successive approximation register analog to digital converter control in synchronized phasor measurement units (PMUs). To compensate for the sampling time error caused by the division remainder between the desirable sampling rate and the oscillator frequency, a variable sampling interval control method is presented by interlacing two integers under a proposed criterion. The frequency of the onboard oscillator is monitored in real-time using the pulse per second (PPS) timing reference from global positioning system. The sampling control is adaptively adjusted each second according to the latest estimated oscillator frequency. The “saw tooth” in phasor angle error and DC offset and spikes in frequency error can be effectively eliminated by applying the proposed method. The simulation and experiment results validate the effectiveness and accuracy of the proposed method, which is believed to be able to greatly improve the performance of PPS-disciplined synchronous sampling methods in PMUs.

A two-phase investment model for optimal allocation of phasor measurement units considering transmission switching

Journal Article Mousavian, Seyedamirabbas ; Valenzuela, Jorge ; Wang, Jianhui - Electric Power Systems Research

Ensuring the reliability of an electrical power system requires a wide-area monitoring and full observability of the state variables. Phasor measurement units (PMUs) collect in real time synchronized phasors of voltages and currents which are used for the observability of the power grid. Due to the considerable cost of installing PMUs, it is not possible to equip all buses with PMUs. In this paper, we propose an integer linear programming model to determine the optimal PMU placement plan in two investment phases. In the first phase, PMUs are installed to achieve full observability of the power grid whereas additional PMUsmore »« less

Synchronized phasor measurements and the ``SYNCHROPHASOR`` standard

Conference Phadke, A G

Synchronized phasor measurements have become a practical proposition only during the last few years. As such, their potential for use in power system applications has not yet been fully realized. Anticipating that this technology is about to take off, the Power System Relaying Committee of the IEEE has developed a standard which defines the interface between the Global Positioning System (GPS) and the Phasor Measuring Unit (PMU), and for the communication link between the PMUs and a remote site. The standard (SYNCHROPHASOR) will be published during 1996, and should facilitate the widespread application of this emerging technology. The standard definesmore »« less
Initial Results in Using a Self-Coherence Method for Detecting Sustained Oscillations

Journal Article Zhou, Ning ; Dagle, Jeffery E. - IEEE Transactions on Power Systems, 30(1):522-530

This paper develops a self-coherence method for detecting sustained oscillations using phasor measurement unit (PMU) data. Sustained oscillations decrease system performance and introduce potential reliability issues. Timely detection of the oscillations at an early stage provides the opportunity for taking remedial reaction. Using high-speed time-synchronized PMU data, this paper details a self-coherence method for detecting sustained oscillation, even when the oscillation amplitude is lower than ambient noise. Simulation and field measurement data are used to evaluate the proposed method’s performance. It is shown that the proposed method can detect sustained oscillations and estimate oscillation frequencies with a low signal-to-noise ratio.more »« less

PMU Data Integrity Evaluation through Analytics on a Virtual Test-Bed

Conference Olama, Mohammed M. ; Shankar, Mallikarjun

Power systems are rapidly becoming populated by phasor measurement units (PMUs) in ever increasing numbers. PMUs are critical components of today s energy management systems, designed to enable near real-time wide area monitoring and control of the electric power system. They are able to measure highly accurate bus voltage phasors as well as branch current phasors incident to the buses at which PMUs are equipped. Synchrophasor data is used for applications varying from state estimation, islanding control, identifying outages, voltage stability detection and correction, disturbance recording, and others. However, PMU-measured readings may suffer from errors due to meter biases ormore »« less
Application of phasor measurements and partial energy analysis in stabilizing large disturbances

Journal Article Stanton, S E ; Slivinsky, C ; Martin, K ; ... - IEEE Transactions on Power Systems

Precise time-synchronized phasor measurements are available to us today from the Phasor Measurement Unit (PMU). One of the most promising uses of the PMU is for during-transient control applications. The work reported in this paper investigated the ability of synchronized Phase Angle Measurements to identify impending instabilities through real time measurements, and to trigger remedial actions in time to prevent major power system outages. At question was feasibility and how many additional Megawatts could be transferred when using the PMU to arm existing during-transient controllers. The Partial Energy Function is defined and explained symbolically in terms of Kimbark`s equal areamore »« less
